Rendering the exterior of a building is typically used to enhance its appearance and provide protection from weathering and rainwater.  Whilst silicone or acrylic ‘through-coloured’ render finishes may seem an economical choice, there can be subsequent problems which can quickly spoil the aesthetics of the building.

Marketed as a long-term render that is structurally sound, there are common issues that can arise which include difficulty when repairing, with repairs to damaged areas resulting in colour and texture differences, which leaves a patchwork effect.

Through coloured renders typically contain petrochemical ingredients, they look fresh when first applied, but over time the components within the render provide an organic food source for contaminants such as algae, which can significantly build up on the render surface.   Petrochemical based pigments within through coloured render are prone to fading under UV light.

KEIM, who have specialised in environmentally, eco-conscious paints since 1878, offer products that can refresh and repair these renders, to provide a protective, breathable, fade free finish which is far more resistant to the build up of algae and mould.

KEIM Soldalit-ME provides the perfect refurbishment and repair solution.

KEIM-Soldalit-ME is a highly specialised sol-silicate exterior mineral paint with photocatalytic qualities, not only is KEIM-Soldalit-ME breathable, fade free and environmentally friendly, it also actively reduces harmful gases and organic pollutants in the atmosphere.

Vanessa Fox, Commercial Manager helps to explain; ‘KEIM have been approached to assist with numerous projects where issues have arisen on through colour render, where façades have faded, where repairs are difficult to carry out, and in particular where significant issues with algae build up have occurred.’

‘By redecorating these buildings using the KEIM-Soldalit-ME system, not only can we transform the look of the façade, we protect the underlying render from the effects of UV light and we offer a surface that restricts the build-up of algae. Our paint helps to clean the air as well as offering fire resistance with a fire classification A2-s1, d0 ideal for use on all manner of projects from heritage to high-rise.’

Vanessa continues, ‘All of our products are designed to be kind to use, and kind to the environment. Our products have been in use for decades and all with proven eco credentials, they are Cradle to Cradle Certified®, and will help protect the building’s exterior from ingress of rainwater to remain fresh and vibrant for years to come.’

  • Redevelopment in Leicester transforms a derelict warehouse into new apartments.
  • The Logik 70mm chamfered system in Black Ash specified as a sustainable alternative to aluminium.
  • With a U-value of 1.2, the Logik 70mm system met the aesthetic and acoustic standards required.
  • Logik, which contains 32% recycled PVC-U, helped reduce the project’s environmental footprint.

Challenges Encountered in Redeveloping a Derelict Site

The redevelopment of a derelict warehouse, alongside the construction of three new apartment blocks in Leicester city centre, presented several significant challenges. Initially, brown aluminium was specified to align with the area’s aesthetic. However, the project’s primary goal was to transform the neglected site into modern, high-quality apartments that would contribute to the wider regeneration efforts in the city centre. In response, Nu Openings proposed the Eurocell PVC-U 70mm Logik Chamfered system in Black Ash and Syncro sliding doors as a more cost-effective and sustainable alternative to aluminium.

This specification change introduced the need for careful adherence to local planning protocols, collaboration with architects, and compliance with Building Regulations. Additionally, the derelict state of the warehouse added complexity to the project. On-site safety during the measurement of every window was paramount, and the team also had to contend with structural irregularities and environmental factors, such as the presence of pigeons.

Innovative Solutions for Modern Apartment Design

Nu Openings, contracted to install the windows and doors, worked closely with Padmore Construction and Eurocell’s Commercial team to overcome these challenges. The choice of the Logik 70mm system was driven by its exceptional thermal performance, achieving a U-value of 1.2, while offering significant cost savings compared to aluminium. Eurocell’s foiled Black Ash finish provided the ideal solution, balancing the need to match local architectural aesthetics with energy efficiency goals.

Steve Carvell from Nu Openings, who spearheaded the specification change, noted the challenge of ensuring that PVC-U could meet both the aesthetic and functional requirements of the project. Eurocell’s Technical team collaborated closely with architects, providing detailed technical drawings and support to secure planning approval, ensuring the project’s success.

Steve shared:

“Convincing the planners and architects to switch from aluminium to PVC-U wasn’t easy. It wasn’t a straight swap – we had to make sure the new material met all the aesthetic, structural, and thermal requirements.

“Eurocell’s Technical team played a crucial role in this process, providing detailed drawings and performance data to demonstrate how Logik 70mm could deliver on energy efficiency, durability, and design. The team’s expertise helped us navigate complex planning approvals and ensured that the new specifications not only met, but exceeded expectations, ultimately securing the confidence of all stakeholders involved.”

Despite the derelict state of the existing building, which required creating new structural openings for window installations and precise on-site measurements, the installation of over 220 frames has been successfully completed. The project involves more than 1,000 frames, with 90% of the installation carried out internally. This approach has minimised the need for external scaffolding, streamlining the process and reducing the impact on pedestrian safety around the site.

Delivering Cost Savings and Sustainability

Although the project is ongoing, the decision to shift from the originally specified aluminium to the Logik 70mm system has already yielded significant cost savings, while delivering high-performance, energy-efficient windows. The chosen design seamlessly integrates with the surrounding architecture, preserving the city’s identity while offering a modern, sustainable solution.

Kelly Hibbert, Head of Commercial at Eurocell, highlighted the critical role of acoustic performance in the project, with bespoke glazing solutions designed to meet rigorous noise reduction standards:

“This project extended far beyond aesthetics – the windows needed to comply with strict acoustic requirements. The successful collaboration between planners, architects, and Nu Openings enabled us to meet every aspect of the design brief, transforming a derelict site into modern, energy-efficient apartments.”

“In addition to the performance benefits that the Logik 70mm system brought to this development, Eurocell’s sustainability credentials were also a key advantage. Our products, containing an average of 32% recycled PVC-U, contribute to the construction sector’s increasing focus on environmental responsibility and the complex journey towards achieving Net Zero.”

The redevelopment of the derelict warehouse, along with the construction of three new buildings as part of this project, aligns seamlessly with the broader initiative to enhance both the functionality and aesthetics of the city.

Clement Windows Group has supplied rooflights from its Clement Conservation Rooflights range for 1-5 St Paul’s Square in Birmingham.

This historic Georgian building is home to multiple office units and a landmark venue known as The Jam House.  Opened in 1999 by Jools Holland designer and Neil Tibbat, the multi award winning venue offers live music and fine dining.

Eleven rooflights from the Clement 3, Clement 4 and Clement side hung ranges, all in a slate profile, were installed at the venue.

Richard Clews from Jubb Clews Ltd, who were the architects working on the project, said:

“1-5 St Paul’s Square is a Grade II Listed Building in Central Birmingham that was constructed in c1780 as town houses around a classic Georgian Square.

The project included repairing the traditional slate roofs and lead-lined parapet gutters.  Key design considerations included improving thermal performance and increasing the capacity of rainwater disposal to accommodate modern storm surges whilst remaining sympathetic to the traditional architectural details.  The works were funded from the planned maintenance budget.

Clement Conservation Rooflights were perfectly suited to this application.  Several of the top hung windows were used for the upper floors whilst the side hung windows were used for the roof maintenance access.”

Manufactured for either a slate or a tile profile and available in eight standard sizes, Clement Conservation Rooflights are constructed from strong mild steel sheet for extra strength, and coated in polyzinc and polyester powder paint for durability.

The rooflights comprise high performance, argon filled, 24mm insulated glass units and come with a revolutionary warm T bar system.  Available with several glazing options, including self-cleaning glass as standard, Clement’s rooflights are manufactured to EN ISO 9001 standards and rigorously tested against air, wind and rain to BS6375.  They have achieved a BFRC Window Energy Rating of A+.

Visit the Jaga website

Jaga UK’s state-of-the-art Briza Net Zero heat pump radiator has been selected to heat and cool some of the first new homes at Welborne, a new generation sustainable garden village near Fareham, Hampshire.

Designed by Buckland Group, Welborne, one of the largest new community projects in the UK, is under construction and will become a place for 15,000 people to live, work and play, consisting of connected and energy efficient homes integrated with extensive publicly accessible green space. This latest announcement reinforces Welborne’s commitment to embedding sustainable solutions throughout the development.

Jaga’s Briza S Net Zero model was chosen for its slimline, elegant design and exceptional energy performance. The compact yet powerful unit provides efficient heating and cooling via Welborne’s ambient water-source heat network – the largest of its kind in the UK.

Developed by Last Mile Heat in collaboration with Rendesco, the sustainable energy network supplies low-carbon heating, cooling, and hot water, helping to significantly reduce the community’s carbon footprint and deliver long-term energy savings for residents.

At the heart of the network is Portsmouth Water’s underground Hoads Hill Reservoir, which provides water at a stable temperature of approximately 10–12ºC. This water is pumped into each home’s heat pump system, where it is warmed to 45ºC before circulating through Jaga’s Briza Net Zero emitters. During the summer, the same system delivers cooling by channelling cooler water through the Briza Net Zero units, providing an efficient, climate-friendly alternative to air conditioning.

The initial phase of the project will supply heating and cooling to 700 new homes, along with commercial premises and community buildings, gradually expanding to serve all planned 6,000 homes and 15,000 residents. Notably, this sustainable energy network is projected to cut CO₂ emissions by 90% compared to gas boilers, saving over 272,000 tonnes of carbon in the first 25 years of operation and providing residents with ongoing energy savings. Recently, the Green Heat Network Fund awarded £2 million to support the network’s development, further reinforcing its positive impact on the environment and local community.

Phil Mangnall, Managing Director of Jaga UK, commented, “We’re incredibly proud to be part of this forward-thinking development that prioritises sustainability and energy efficiency. Our Briza Net Zero emitters are specifically designed to work seamlessly with renewable energy systems, delivering high heat output at lower flow temperatures. This means less energy is needed to heat the water from the reservoir, creating a highly efficient system. Their slimline, sleek design also complements the timeless architecture of the homes, adding both style and functionality. It’s exciting to see these emitters play a key role in the UK’s largest water-source heating and cooling network.”

In delivering this ambitious project, Jaga UK is collaborating with Welborne’s housebuilder partners, including Thakeham, Pye Homes and CG Fry. These developers are creating sustainable and high-quality homes to meet the needs of future generations. Jaga is also working closely with the developers’ chosen heat pump partners, NIBE and others, to provide a cohesive heating and cooling system for each development.

Welborne Garden Village is an ongoing development, and prospective residents will benefit from new schools, healthcare, sports and leisure facilities, along with a range of retailers, and a science and technology park. Taking a nature-led design approach, more than 50% of Welborne will be accessible green space woven throughout, and the garden village will be biodiversity positive with wildlife and natural habitats restored from previously intensively farmed agricultural land.

Construction on the first phase began in 2024, and Welborne will welcome its first residents early this year.
