IMG_9637 (1)Original Crittall windows have been replaced and upgraded on the main street frontage of one of Leeds’ most historic quarters.

Briggate is a pedestrianised principal shopping street in the city centre containing many historic buildings including, tucked away from view in Lamberts Yard, the only remaining Elizabethan timber framed property in the City dating back to circa 1600.

The walkway leading to that heritage enclave passes through No. 162 Briggate, a 1950’s vintage commercial and residential block where Think Architecture has installed replacement Crittall steel windows.

“No.162 had original Crittalls and, as with all the buildings around Lamberts Yard, things were in various appalling states,” said Simon Smithson, director of Pudsey, West Yorkshire-based, Think Architecture.

The original single glazed windows in the three-storey no.162 were replaced with double glazed lookalike Homelight windows. The building now houses new apartments and a ground-floor commercial premises.

“I have to say,” added Mr Smithson, “ that the Crittall windows are a wonderful system. Several years ago we did a job and used what was described as a ‘Crittall-like’ system. Well, that was very disappointing whereas the Crittall system is a great system, so well made.”

Orbit Housing’s Fordham House in Stratford-upon-Avon aims to raise the bar for rented accommodation. Although initially a social housing provider, Orbit now refers to itself as a “developing housing association”, and Fordham House is designed for private rental by key workers in the town.

Fordham House Orbit Homes 30-10-17 (31)The 82-apartment block provides enhanced protection against noise, a superior maintenance and repair strategy and additional facilities such as secure internal bike storage rooms. Much of the budget for these above-and-beyond features has come from the specification of Modus PVC-U windows from Eurocell in place of the aluminium frames originally specified.

The result was a significant reduction in costs, with no compromise on building design and performance. Despite the building being located on the busiest road in Stratford, residents have been satisfied with the noise suppression provided. Confirmation of the Fordham House project quality came with major award wins in the 2019 Inside Housing Development Awards – Best Build for Rent Development and RICS Residential Property of the year (West Midlands).

Fordham House was also awarded Residential Property of the Year at the Royal Institute of Chartered Surveyors (RICS) awards, West Midlands in 2019.

Constructed from dense concrete blocks with hollowcore flooring, the three- and four-storey building is clad in a mixture of curtain walling and green wall – sections of planted walls which will be automatically fed and irrigated. The Modus windows, supplied and installed by Unique Window Systems, are tilt-and-turn so that they can be cleaned internally, avoiding the potential hazard and traffic issues of accessing them from the elevations by the two busy roads.

Picture 1With many tenants expected to come from expanding local hospitals, acoustic improvements were high on the menu of potential value enhancing features. Orbit has beefed up the acoustic barriers between floors with a layer of insulation and screed with suspended ceilings added to the deep hollow concrete slab. It has also added fitted blinds within the reveals of the windows to provide an additional noise cushion for shift workers who need to sleep during the day.

BBA-certified to function satisfactorily for more than 35 years, the Modus range achieves a U-value of 1.2 W/m² using 4/20/4 mm sealed double-glazed units. This effective thermal performance is due to the 75mm six-chamber profile system used in the Modus system that also enables the range to achieve a U-value of 0.7 by installing triple-glazed units.

This led to Modus becoming one of the very first systems to achieve the BFRC Window Energy Rating (WER) of A++. This is only awarded to windows with an energy index value equal to or greater than +20; and Modus A++ designs include casement, reversible and tilt and turn.

Additional budget gained from savings on the window costs has also gone into upgrading the flooring material. Ceramic wood-effect flooring has replaced lino to provide a longer life and hence lower maintenance costs and down-time for Orbit.

A re-think of the building’s layout produced space for a substantial ‘spares room’ which will house items such as cookers and kitchen units. With all the apartments kitted out identically, this will enable faster repairs and reduce the time required to spruce up homes between tenancies.

BILCO Service Stair with Type L-50TB Roof Hatch

Are you choosing the right roof access hatch and ladder for your project?

Building Products Index Ltd Access Hatches, access solutions Leave a Comment

View the Bilco entry on BPindex

Visit the Bilco website

Whether you are working on a commercial or residential project, there are a number of factors that must be addressed when deciding on a roof access hatch and accompanying ladder to ensure its safe and compliant application for the entire lifecycle of the building.

 Here Tony Stevens, Technical Estimator at Bilco UK, explores the main areas that should be taken into consideration. 

  • Purpose for access

BILCO Service Stair with Type L-50TB Roof Hatch copyWhether  for the education, healthcare, leisure or commercial sectors, roof access hatches are required to provide permanent and secure access to the roof area. In order to make sure you’re choosing the correct system to meet your project’s unique requirements, you must first identify the main reason for requiring access to the roof.

Is it purely for maintenance reasons? Or will a safe means of access also be required for the regular installation or removal of equipment from the roof?

Here you should also identify what tools and equipment will need to be transferred through the access hatch, or whether it will just be the individual that is conducting the necessary work.

  • Frequency and product specification

Once you have established your reason for requiring safe access to the roof, you will then be able to make an informed choice regarding which roof access hatch and corresponding ladder system is best suited to meet the needs of your project.

The first considerations that must be addressed when specifying a ladder to gain roof access is where the ladder will be mounted and the requirement of any additional safety elements to ensure the continued safety of the individual when using the system. If a ladder is to be mounted externally to gain access to a roof, it must be fitted with a safety cage and guard rail to ensure safe and secure access.

Bilco S-50T Roof Access Hatch installed at Brentwood Community HospitalFor a small roof access hatch, such as the Bilco E-50TB, which has internal dimensions of 915mm x 915mm, a fixed vertical ladder should be chosen. This type of ladder is also the most suitable option for projects where space is limited.

In this instance, a retractable ladder would not be recommended, as the ladder angle would hinder easy access as an individual moved closer to the hatch. However, retractable ladders are ideal for use in areas including schools and hospitals where the roof hatch is larger, at around 1500 mm in size and the floor area must be kept clear at all times.

To ensure easy and safe access, a minimum head clearance of 120mm is required, whilst the maximum single climb should be no more than three metres, in accordance with BS4211-7.2.

If access to the roof is required on a regular basis for professionals that will have to transfer tools and equipment through the hatch, a Fixed Staircase Roof Access Hatch, also known as a Service Stair Roof Access Hatch, should be specified with a Companionway Ladder or a Fixed Staircase. The companionway ladder is a 75 degree angled, rigid ladder, which provides permanent access to a roof hatch of up to 2440mm.

It should here be noted that the roof hatch must be sufficient to maintain a head clearance of 2000mm, as detailed in Building Regulations Part K.

When specifying a retractable ladder, it is essential that you know the height of the space between the ceiling and the roof, more commonly known as the roof void. This is to ensure the ladder box liner will fit inside the space once retracted. Calculating the height of the floor to the underside of the roof access hatch should also be done at the initial stages to ensure the ladder isn’t too short or long.

Regardless of the size of the roof access hatch, the system should be operated easily and safely with one hand, in accordance with the requirements outlined within the Manual Handling Regulations, enabling the individual to maintain three points of contact with the fixed ladder.

During the installation process, the ladder must be positioned opposite the hinge to ensure safe and unobstructed access.

  • Bespoke requirements

To ensure the criteria is successfully met, consideration should be given to the wider options available for both the roof access hatch and corresponding ladder.

ladder-wcage-video-screenshot copyFor example, ladders that are supplied with relevant fire ratings and available with vertical backboards that include steps and a handrail for enhanced safety and security should also be considered to meet relevant building regulations.

Increased access opening sizes or double leaf configurations should also be explored where access is required for larger items of equipment or tools. Motorised options also allow the individual to safely maintain contact with the ladder when entering or exiting the hatch.

Regardless of the project type, all installations should be subject to individual Risk Assessments. Comprehensive training should also be provided for all professionals, supported by Method Statements regarding safe and correct use of the access solutions installed.

Rundum Meir garage doors

A unique garage door fit for one of Scotland’s ‘homes of the year’

Tom Manley_RM_Trager_Glasgow_Low Res2Contemporary architecture is continuously pushing the boundaries and redefining the purpose of familiar building elements, including the garage door as the unique TrägerHAUS dwelling near Glasgow demonstrates.

The award-winning property by architects HAUS Collective features an elegant, completely bespoke side sliding sectional garage door designed, manufactured and installed by Rundum Meir. This distinctive feature on the house’s outward facing elevation, is one of the first elements that greets anyone visiting the property, which is why it was important to ensure its design and quality is fitting for an ultra-high specification house.

The TrägerHAUS was a finalist in the BBC’s 2020 Scotland’s Home of the Year awards. During their visit, the competition’s judges described the house as “a really well-made building” and, during a discussion on the property’s appearance on arrival, one judge commented how “it is difficult to make something look that neat with so few materials.”

Tom Manley_RM_Trager_Glasgow_Low Res3But it is not only the BBC Home of the Year judges who have been drawn to the TrägerHAUS. The ambitious contemporary residence, which extends to approximately 3,750 square feet, was also named as one of the top 100 houses in Scotland since 2000 by the Royal Incorporation of Architects in Scotland (RIAS).

Built on the periphery of the Upper Whitecraigs Conservation Area on a plot that slopes down from a main thoroughfare, the TrägerHAUS sits comfortably in its residential context being relatively unassuming – disguising its more dramatic architecture at the rear.

Whilst the scale and main volume of the house may not be apparent at street level, this does not detract from the visual appeal of the property as a result of careful consideration of the materials for the home’s outward-looking elevation and main entrance.

Tom Manley_RM_Trager_Low Res_4Key to this was the decision to utilise an elegant Rundum Meir side sliding sectional garage door. The door’s manufacture in Siberian Larch ensures consistency with property’s other timber cladding elements which perfectly complement the Caithness stone masonry. Fully automated for ease of opening and closing, the garage door operates with the smoothness and reliability that reflects the level of quality which runs through the whole building.

As with all Rundum Meir garage doors, this side sectional door was bespoke manufactured by its team of skilled craftsmen and women in Germany. As each door is made to order in numerous types of timber, including Nordic Spruce, Superior Spruce, Larch, Hemlock, Oak and Sapele, any architectural specification can be easily accommodated. This provides the freedom to design the external envelope to incorporate an interesting garage door feature that makes a significant contribution to delivering on the client’s aesthetic ambitions.

Rundum Meir side sliding sectional garage doors features panels suspended from a top track, which slot perfectly into either a traditional U-channel with drainage facilities, or a surface mounted T-bar at the foot of the door. Constructed with a double skin timber insulation and fittings which require little maintenance, the doors offer exceptional stability and durability, conforming to all relevant building standards including BS EN 13241 Part 1 Industrial, commercial and garage doors and gates for total peace of mind.

Radmat non-combustible insulation

Do you need non-combustible insulation on flat roof and balcony upstands?

Building Products Index Ltd Insulation Leave a Comment

View the Radmat entry on BPindex

Visit the Radmat website

This is a question worthy of the QI TV show, and one that would definitely get Alan Davies the famous Klaxon and flashing lights because the obvious answers of yes or no would both be incorrect.

ProTherm XPS-X-300RockFace-A2-UpstandAt present, based on the current wording in Approved Document B fire safety, the only clear YES answer is where the roof upstand is against habitable space ‘on a relevant building’, then you must use non-combustible insulation. Whether non-combustible insulation is required for parapet walls, rooflight kerbs, upstands etc. is not clear in Approved Document B fire safety, and is one area where it is hoped that the long-awaited response to the Ministry of Housing Communities & Local Government (MHCLG) consultation on Regulation 7 will provide clarity.

In the meantime, the major flat roofing industry Trade Associations have come together to produce a guidance document based on the understanding of the current regulations and the ‘direction of travel’ indicated by MHCLG.  The guidance within the document is endorsed by the NHBC.

NFRC/LRWA/SPRA Guidance Document

This new document, published in mid-June 2021, clarifies that a combustible insulation board can be used on any flat roof upstand, but it:

  1. cannot extend more than 150mm above the roof finish/walking surface
  2. cannot be thicker than 60mm
  3. cannot span across a compartment wall line
  4. cannot be against habitable space

If any one of these requirements is not met then the insulation must be non-combustible i.e., suitable variants of FOAMGLAS or Rockwool that meet Reaction to Fire Class A1 or A2-s1, d0 to BS EN 13501-1.

RockFace A2 Product high resThe Guidance Document also highlights that all upstands on balconies (‘waterproofing’ over air rather than over heated space) are classified as part of a ‘Specified attachment’, and therefore all upstand insulation board must be non-combustible.
But how will this knowledge transfer to the real world of on-site construction, or the purchasing office? Will the installers be provided with the knowledge to understand where they can use combustible insulation and where they cannot? Will they know where the compartment wall lines are when waterproofing a roof or terrace?

BPI Upstand Detail

Whilst you can use combustible insulation within the legal requirements of Approved Document B, wouldn’t it be simpler to standardise all your flat roof specifications so that all the upstand insulation is non-combustible? This would avoid any confusion on site, avoid any risk of error and avoid any risk of having to pay for the removal and replacement of the incorrect insulation board.

Also, don’t forget to specify the vertical insulation from deck/vcl level upwards so as to provide a fire break between the combustible insulation running across the roof and the external wall.

Jenny Smith-Andrews, Head of Marketing at aircrete specialist H+H UK Ltd outlines the sustainability arguments for masonry buildings

Caddington Woods LUTON Nov 2020 11H+H has always seen itself as a manufacturer that supports sustainable building – but over time, the definition of the term and priorities for the building industry have shifted. It is good therefore to see some consensus emerging on the objectives for sustainability and how each industry can meet them. H+H supports the principles set out in the UN Sustainability goals and is committed to supporting this agenda.

Reducing carbon

Church Farm Rode -50-EditThe first, and increasingly urgent, priority is to reduce carbon emissions. When it comes to housebuilding that means a focus on reducing the energy demand of our homes. Home heating alone contributes around 19% of the total CO2 produced in England each year so it is logical that building regulations and the Future Homes Standard are looking to increase further the thermal efficiency of new buildings.

Aircrete has a part to play in this agenda. With its inherent thermal efficiency and very effective airtightness, the material has always been a good choice for energy efficient homes. In fact, H+H was involved well over a decade ago in the development of prototype zero carbon homes.

Cameron Close Passivhaus copyMore recently, aircrete has been used as the foundation of low energy homes for social housing schemes where fuel costs are a primary concern and Passivhaus designs offer a practical solution.

When it comes to revisions to Building Regulations Part L, aircrete is well suited to the newer, more stringent standards and a familiar cavity wall construction will meet all the revisions currently planned.

Operational zero carbon is only one part of the story, however, and attention is increasingly focused on embodied carbon. Moving to net zero manufacturing is challenging and requires the whole supply chain to be working to the same goal.

pollington blocks and wind turbineH+H has published its roadmap to zero carbon, outlining a journey that will decarbonise its manufacturing and transport processes. However, even in this objective there can be a degree of interpretation and different measurement techniques.

Our response is to use robust lifecycle analysis methods including all the manufacturing, in use and post-use phases of construction. It is essential to develop commonly agreed standards for calculation to provide a level playing field and ensure that all manufacturers are basing their claims on equivalent data sets.

In its planned journey to zero carbon by 2050, H+H is relying on science-based targets to provide a benchmark against which to measure progress.

A Sustainable future

Low carbon construction is the focus at the moment, but at the same time, lifespan and resilience of new homes must form part of a sustainability strategy.

There is little point in reducing manufacturing carbon if the resulting building only lasts for a few decades and then needs to be entirely replaced. There is an increasingly significant school of thought suggesting that the most sustainable building is one that will last a very, very long time.

Coping with extreme weather conditions

And during its lifetime, the building will need to withstand the extremes of a changing climate. In its June 2021 Assessment of UK Climate Risk, the Committee for Climate change cited overheating and flooding as the two most significant risks for the housing sector.

H+H would point to the 150-year lifespan, inherent resilience and thermal mass characteristics of aircrete to further support its position as a material with a secure future in modern, sustainable housing.

Main newsletter imageKnauf Dry Screed Flooring Systems are ideal for a wide range of projects and have multiple benefits compared to traditional wet screed. They are lighter, fast to traffic and suitable for modern construction methods (MMC).

The dry screed boards are up to 75% lighter than traditional wet screed, which is in part due to them being significantly thinner. This makes Knauf’s dry screed flooring systems ideal for retrofit and refurbishment projects, as the thinner boards maximise floor to ceiling height.

Image 4As the name suggests, dry screed flooring requires no protracted drying time. This means the systems are ready for foot traffic within 24 hours, much faster than the 2–7 day wait for wet screed systems to dry. This also allows for follow on trades to begin work much sooner, therefore having the potential to reduce overall build time.

24 April 2013: Knauf flooring being laid at Elliott Modular in Bridlington. Picture: Sean Spencer/Hull News & Pictures 01482 210267/07976 433960 www.hullnews.co.uk   sean@hullnews.co.uk

If underfloor heating is being installed on the project, the Knauf boards are particularly beneficial. The low thermal resistance and high thermal conductivity of our boards assist in improving response times whether you are heating or cooling the floor, thus reducing energy consumption.

The sustainability credentials don’t end there either. No water is required during installation and, due to their being lightweight, less substantial concrete or steel substructures and reduced foundations are needed to install the boards. This all translates to the conservation of valuable resources.

The Knauf range includes Knauf Brio, Brio WF, GIFAfloor HUGO and GIFAfloor FHB.

Image 3 CopyKnauf Brio is a medium density floor panel that is installed onto a solid floor, although this can be either an existing solid subfloor or in a floating construction. Knauf Brio is 43% more thermally efficient than chipboard when used in conjunction with underfloor heating systems.

Knauf Brio WF is a dry screed floor panel backed with wood-fibre to provide excellent acoustic performance and sound reduction which help to effectively reduce noise transmission.

Knauf GIFAfloor HUGO is a medium density gypsum fibre panel engineered with tongue and groove edges for ease of installation.

Image 2 CopyKnauf GIFAfloor FHB is a high density dry screed panel able to span between joists and pedestals due to its structural spanning capabilities. Being a hollow flooring system and having high thermal conductivity makes GIFAfloor panels ideal for underfloor heating systems.

The products come in the form of interlocking panels for improved robustness and making them easier to lay. They can also be covered with a range of finishes, including ceramic or natural stone tiles.

All Knauf flooring systems are precision engineered from the highest-quality gypsum fibreboard to create strong monolithic floor structures. To find out more, please visit https://www.knauf.co.uk/systems-and-products/dry-screed-flooring
