In landscape and urban design, materials must do more than meet a specification — they must contribute to the character of a space and continue to perform over time. For over 45 years, Addagrip has supported architects, landscape designers, and contractors with resin bound surfacing solutions that balance aesthetics with long-term reliability.

Used across public realm, heritage, and high-footfall environments, Addagrip systems are trusted because they deliver consistent performance in real-world conditions. This proven track record gives specifiers confidence that surfaces will not only look right on completion, but continue to function as intended for years to come.

Resin bound surfacing offers a seamless, permeable finish that can be tailored using natural aggregates to complement a wide range of settings. As well as enhancing visual quality, permeability supports SuDS principles, helping manage surface water within the wider landscape design.

Performance remains central to specification. Durability, slip resistance, accessibility, and low maintenance are all critical considerations, particularly in public spaces. Addagrip systems are designed to meet these demands, providing smooth, consistent surfaces that support inclusive access and ease of use.

Sustainability is also a key focus, with solutions that incorporate recycled materials and support efficient drainage. Combined with long-term durability, this helps reduce the need for future intervention, contributing to more sustainable outcomes over the lifecycle of a project.

Working closely with specifiers from concept through to completion, Addagrip ensures that each system is aligned with both the design intent and performance requirements of the scheme.

Berkshire Residential Project

This Berkshire new build is the result of extensive design development and careful construction coordination, bringing together the many considerations required to deliver a refined long-term family home.

 

The house was designed by NEON Architecture, a design-led Architects practice based in Berkshire. They guided the project through each stage of the RIBA Plan of Work. Working closely with the clients, the practice developed the brief from early concept through to the delivery of a completed home. The intention from the outset was to create a long-term family house reflecting the clients’ interest in both industrial character and the proportion of Georgian architecture.

Traditional Georgian principles informed the overall composition of the building. A villa-style form is centred around a generous two-storey entrance hall, complete with a fully vaulted rooflight that allows natural light to travel deep into the interior and gives the house a strong central focus. Contemporary elements were introduced where needed to control the visual massing and maintain balance across the overall form.

A particularly distinctive part of the project is the garage, which was conceived as an integral architectural element rather than a purely functional space.

The building features a full-height curved side sliding timber solid oak door by Rundum Meir which exudes simplicity as it runs across an 8 meter opening.

Unlike conventional garage doors, this curved sliding system allows the door to follow the form of the building, maintaining clean lines across the façade while resolving a large opening in a controlled and visually integrated way.

The fully automated faceted door follows the curve of the garage wall and operates on a discrete track system that allows it to slide beautifully around the internal plan of the building. The detailing of the track enables the mechanism to remain largely unobtrusive while preserving the usable floor and ceiling space within the garage.

When opened, the door wraps neatly along the internal wall. At dusk, the lighting within the garage spills out across the rendered walls, highlighting the movement of the door as it slides aside. Rob Butcher, of Neon Architecture, describes it ‘creating an almost theatrical experience to present the client’s beautifully curated collection of influential cars’.

Catherine Wilman Interiors led the interior design, introducing considered materials, textiles and finishes to complement the architectural language of the house. The palette balances soft, robust tones with natural timber and stone, reinforcing the connection between interior and exterior.

Rundum Meir combines precision engineering with bespoke design to deliver side sliding timber garage doors tailored to each project. Systems such as this are particularly suited to architect-designed homes, large garage openings and situations where a standard up-and-over or sectional door would compromise the design intent.

Visit the Wavin website

Leading plumbing and drainage manufacturer Wavin expands its Mechanical Ventilation Heat Recovery solutions with the launch of the new Ventiza FlexPro-90, a higher-capacity semi-rigid radial duct developed to meet the increased airflow demands of modern, energy-efficient homes.

The new 90mm duct builds on the Ventiza FlexPro‑75 system introduced last year, delivering up to 45% more airflow than standard 75mm options at the same velocity levels – enabling installers to achieve required ventilation rates using fewer ducts.

The increased airflow capacity lowers the back pressure and enables MVHR units to operate at lower speeds, helping to reduce energy consumption and lower system noise for homeowners.

Supplied in continuous 50‑metre coils, the new semi-rigid radial duct reduces the number of joints required, supporting simpler installation and minimising air leakage risk.

The duct’s double‑wall construction includes an insulating air void to support improved acoustic and thermal performance, contributing to quieter operation within the home. The material also incorporates antibacterial, antifungal, and antistatic properties to help maintain air‑quality standards and reduce dust build‑up inside the system over time.

Features of the Ventiza FlexPro range include a smooth internal surface designed to reduce air resistance, and a ribbed exterior providing high mechanical strength and impact resistance suitable for on‑site conditions.

FlexPro‑90 is available now, with a full range of connectors to be introduced in May. The duct has been designed to remain compatible with existing connectors on the market, so ongoing projects can adopt the new system without delay.

Ben Perris Sales Director for Indoor Climate Solutions for Wavin said: “The launch of FlexPro‑90 is a great example of our commitment to giving installers and developers the flexibility they need to design high‑performing, future‑ready ventilation systems in action. Its increased airflow capacity supports the growing demands of modern, energy‑efficient homes, while helping installers create simpler, more efficient systems with less noise and lower energy use.”

Alongside the new Ventiza FlexPro range, Wavin’s online Ventilation System Finder supports early‑stage project design by helping built environment professionals identify the correct ducting configuration and suitable MVHR unit for their specification.

Following system selection, Wavin’s technical team works directly with developers and installers throughout design and installation, helping to ensure accurate system performance and smoother project delivery.

What is Toupret’s plasterboard finishing range?

It’s a complete system for taping and jointing, not just individual products, but a fully integrated range designed to work seamlessly together. Built with Toupret’s trademark quality and reliability, the system helps save time on site while delivering a professional finish.

The range is made up of a powder Joint Filler, a ready to use Finish Filler, an extra sticky Adhesive Scrim, a paper Joint Tape, and a reinforced Metal Corner Tape – everything needed to complete the job efficiently.

Why is Finish Filler being called a game-changer?

It addresses the biggest frustration in joint finishing: sanding time. We spent time with tapers and jointers across the country and discovered ease of sanding is the top priority for professionals, and Finish Filler sands effortlessly, meaning fewer passes and faster results.

There’s no bubbling, so no drywall sealer is required, and no priming before painting. The bucket is also designed to fit an automatic taper pump – just plunge, pump and tape.

What’s revolutionary about Joint Filler?

Alongside a standard 1-hour working time, there’s a 3-hour option. Longer working time means fewer mixes, larger batches and more jointing before stopping to clean up, saving time overall. It can also be used on painted surfaces for patch repairs.

Why choose a full system?

Reliability and convenience. Every product is designed to work together, reducing frustrations and delivering consistent, professional results.

Visit the KEIM website

Builders, home improvers, and designers add render to facades for several reasons;   to protect the structure, improve the aesthetics, and to boost energy efficiency. But if the products aren’t used effectively, or applied incorrectly, they can cause lasting problems that they were designed to overcome, such as water ingress, trapping moisture, which can lead to cracking or damp.

KEIM Mineral Paints Limited are known for their natural, environmentally friendly interior and exterior paints, but here we focus on their lesser-known range of renders; each designed for specific applications but all providing lasting durability, protection, and performance.

Why do we render?

There are several reasons why we would choose to apply render. The common reasons include;

  • Protection from the weather – water soaking, reduce damp, in wet climates
  • Improve structural durability – cover cracks, stabilise aging masonry
  • Aesthetic upgrade – modernise older properties, add colour or texture
  • Improve insulation – keep heat in during winter, lower heating bills

How KEIM is different

Typical render types available include cement, lime, acrylic, and silicone based. KEIM renders, as with all KEIM products, use natural, inorganic ingredients, reflecting the philosophy that dates to 1878, of being kind to use and kind to the environment.

Advantages of KEIM mineral renders;

  • Environmentally friendly ISO 14001
  • High vapour permeability (walls can breathe)
  • Provides durable, colour stable protection
  • Fire resistant to A1
  • UV stable
  • Increases light reflectivity
  • Available in bagged powder form

Products include

  • KEIM Uniputz 1.3 (KEIM Universal Render), multi-purpose, pre bagged mineral render, versatile, easy to apply. Extremely flexible to accommodate high degree of movement such as thermal expansion, whilst preventing the surface from crazing or cracking
  • KEIM Uniputz 0.6 version (KEIM Universal Render Fine). A ready to use product ideal for interior or exterior application using hydraulic lime, white cement with sand and mineral fibre fillers
  • KEIM NHL-KP 3.0 (KEIM Kalkputz Grob), perfect for localised patch repairs of existing lime rendered facades and lime base coat for KEIM NHL-KP 0.6
  • KEIM NHL-KP 0.6 (KEIM Kalkputz Fine), a complete thin lime coat system to be subsequently painted

Where can they be used?

  • Concealing cracks, flaking, or differences in textures
  • Ideal for renovation, historic monuments, listed buildings (KEIM Uniputz 1.3)
  • Can also be applied onto existing sound render
  • Used as a total render or for patch repairs
  • Ideal for use with KEIM’s range of interior and exterior paints

Cradle to Cradle Certified.

Alumasc Launches Skyline Rainscreen Cladding: A Refined Solution for Prestigious Facades

Alumasc Water Management Solutions (AWMS) has expanded its Skyline Architectural Aluminium offering with Skyline Rainscreen Cladding: a premium aluminium system developed to meet the aesthetic and performance demands of prestigious developments, where visual impact and long-term durability are paramount. 

Designed with architects and designers in mind, Skyline Rainscreen Cladding is CWCT tested, and engineered to combine clean, contemporary lines with robust technical performance. It elevates the architectural character of any façade; ensuring maximum weather protection and building compliance.

Designers can specify either Secret Fix Panels or Cassette Panels, each offering its own distinct visual benefits and straightforward installation methods. Panels are available in a wide range of colours and finishes, to support creative freedom on commercial, residential, leisure and mixed-use developments. 

Secret Fix Panels – Seamless Design Freedom

Skyline Secret Fix Panels are designed to deliver a flawless, uninterrupted façade aesthetic. Fixings are concealed by each subsequent panel, leaving no visible fixings. This creates a sleek, high-quality finish particularly well suited to landmark or design-led schemes. Installation can be vertical or horizontal, offering flexibility in façade composition, and enabling architects to respond creatively to building form and proportion.

The interlocking panel design incorporates discreet shadow gaps – 4mm on the shorter edges and 10mm on longer edges – adding depth to the façade without any visual clutter. Available in face widths from 300mm to 700mm, and fully customisable in size and colour, Secret Fix Panels allow equally for bold architectural statements and more understated, elegant expressions. 

Cassette Panels – strong lines and contemporary definition

For projects seeking a more pronounced architectural expression, Skyline Cassette Panels provide a striking alternative. The precision-engineered cassette system features an overlapping joint design with a bold 25mm shadow gap. Discreet colour-coded fixings are neatly located within the shadow gap, allowing for efficient installation whilst maintaining flawless clean lines.

Cassette Panels are installed in a vertical orientation only, and are available in face widths from 250mm to 750mm. Designers can combine varying panel sizes across the façade to introduce texture, scale and visual interest.  

CWCT Testing

Achieving the standard set by the Centre for Window and Cladding Technology (CWCT) involves rigorous testing for watertightness, air permeability, wind resistance and impact resistance. 

CWCT Testing is one of the industry’s most demanding assessment standards, evaluating the entire system including the panels, fixings, joints, rails, and supporting structure.

For AWMS, this testing isn’t just about compliance. It’s a commitment to specifying architects, providing them with assurance that Skyline Rainscreen Cladding is designed, engineered, and validated to perform consistently under the harshest of real-world conditions. 

Robust UK Manufacture, Efficient Installation

Both Secret Fix and Cassette Panels share comprehensive manufacturing and installation benefits. 

The range offers an extensive colour palette, including 27 standard Qualicoat-certified colours. We can also match any BS or RAL colour of choice, including anodic colours and stone-effect finishes. When powder coated, aluminium achieves a fire rating of A2-s1,d0 in accordance with BS EN 13501-1:2018, supporting compliance on demanding projects.

Manufactured entirely in the UK from 3mm-thick aluminium, Skyline Rainscreen Cladding panels are produced under ISO 9001 quality accreditation and ISO 14001 environmental management standards. Aluminium’s inherent durability offers a life expectancy of up to 40 years in rural or suburban environments and up to 25 years in industrial or marine locations, while remaining 100% recyclable.

Installation is straightforward via Skyline’s rail and bracket system, with panels typically installed from top to bottom, left to right.  Both systems are fully compatible with other Skyline elements, including fascias, soffits, copings, window surrounds and door canopies, ensuring a cohesive future-proof envelope design for today’s most ambitious architectural projects.

Technical Expertise and Support

Every Skyline project benefits from the backing of Alumasc’s technical experts, who provide detailed design guidance, bespoke CAD drawings, and on-site support from concept to completion. The Skyline technical team has contributed to the design and detailing of some of the UK’s most prestigious developments. Their collaborative approach ensures each installation is tailored precisely to the project’s needs, delivering optimal performance and the best possible architectural finish.

Building Better Social Housing with Aluminium

Building Products Index Ltd Aluminium building products Leave a Comment

Visit the Dales Fabrication website

How Dales Fabrications is Helping Deliver the UK’s Next Generation of Social Homes

The UK government’s £39 billion Social and Affordable Homes Programme aims to deliver 300,000 new homes by 2036. For housing associations, local authorities, and registered providers, however, the challenge goes beyond delivery targets.

Evolving regulations, including updates to the Decent Homes Standard, the introduction of Awaab’s Law, and new requirements to proactively manage damp and mould are raising expectations for social housing throughout a home’s entire lifecycle, not just at handover. Meanwhile, Minimum Energy Efficiency Standards (MEES) require rental homes to meet EPC Band C, where feasible, by 2030.

These changes are shifting focus toward long-term performance. The materials and systems specified at the design stage can have lasting effects. Choosing the right solutions early is crucial for creating homes that are durable, energy-efficient, and low-maintenance – while avoiding costly repairs in the future.

Aluminium in Social Housing

Aluminium is increasingly being specified across social housing projects due to its combination of durability, low maintenance requirements, and design flexibility.

Unlike timber or untreated steel, aluminium does not warp, rot, or corrode in typical UK conditions. This makes it particularly well-suited to applications exposed to the elements, where long-term reliability is essential. Its stability over time helps reduce the need for ongoing repairs – an important consideration for housing providers managing large portfolios. Additionally, its lightweight nature aids installation, making it safer, faster, and more efficient.

Practical Aluminium Solutions from Dales Fabrications

A range of aluminium systems can be integrated into social housing developments to support both durability and occupant comfort, with Dales Fabrications offering solutions across each of these key areas. These include:

  • Eaves systems – protect roof edges and manage water runoff.
  • Solar shading – reduce heat in homes, keeping residents comfortable and energy bills down.
  • Rainscreen cladding panels – create modern, durable façades that are easy to maintain.
  • Wall coping systems – protect parapets and exposed roof edges.
  • Rainwater systems – gutters and downpipes designed to control runoff and reduce the risk of damp.

Dales Fabrications’ aluminium systems are available in standard sizes or can be customised to suit specific project requirements. An extensive range of colours and finishes – including RAL, BS, metallic, and anodised options – also helps specifiers meet aesthetic and planning requirements, as well as enhancing durability.

Each project is supported by a dedicated Dales Project Manager, with CAD drawings, BIM models, NBS specifications, and early-stage technical guidance provided to assist design integration. Dales also holds professional indemnity insurance of up to £5 million, offering added reassurance, and can support installation through its Preferred Installer network with supply-and-fix options.

Building Homes that Last

Social housing is judged not only at completion but over decades of use. Materials that can withstand environmental exposure, reduce maintenance demands, and support compliance with evolving regulations are essential.

Through its range of aluminium systems and technical support, Dales Fabrications helps housing providers and specifiers deliver homes that remain safe, dry, and efficient over the long term – supporting both residents and asset performance.

About Dales Fabrications

Founded in 1977, Dales Fabrications has nearly 50 years of experience designing and manufacturing aluminium building products. Operating from their factories in Ilkeston, Derbyshire, and holding ISO 9001:2015 and ISO 14001:2015 certification, they bring proven expertise to every project.
