Showcasing the best in external wall insulation

The INCA Awards highlight the top projects using EWI, with the latest winners including a Hindu temple, student housing and concession pods at Lord’s

INCA, the Insulated Render and Cladding Association, is celebrating its 40th year and is now established as the leading organisation representing the external wall insulation (EWI) industry.

The recent INCA Awards showcased the industry’s best projects completed in the previous 12 months.

These three projects demonstrate the variety of schemes carried out in the new-build and refurbishment sectors, providing architects with a full range of innovative finishes to choose from:

Winner of New Build Scheme with a Render Finish 2021: Anoopam Mission in Uxbridge, west London

The architect and client specified Dryvit’s Outsulation system combined with a limestone texture finish, selected for its long-term durability, energy efficiency and adaptability.

An important consideration was the finished aesthetics of the building with the client wishing to echo the features of an Indian temple.

Careful consideration was necessary to ensure the EWI system achieved the desired U-value of 0.24 W/m2K, while emulating the natural stone effect within a traditional place of worship.

Using preformed insulation shapes, the approved installer worked to the Dryvit specification, achieving a serene building for members of Anoopam Mission.

Winner of New Build Project with a Brick Finish 2021: Howard Gardens student accommodation, Cardiff

The £20 million development near the city centre has 390 bedrooms across four and five-storey apartment blocks and a focal point 11-storey building with its courtyard surround. 

System designer SPSenvirowall was invited to propose an external wall insulation system fixed to a hybrid steel frame and SFS project. The selected system was Wall System 1, installed by INCA member Build-Therm Services.

Across 3,000m2 of external facade, 150mm mineral wool insulation was used, with SPSenvirowall SpeedySlip flexible bricks creating the superior, consistent finish.

Flexible brick slips are an ideal solution for developments like this one with limited space. They have an A2-s1,d0 fire-rated classification in accordance with BS EN13501-1 for external cladding.

Winner of Architectural Design 2021: Edrich and Compton stands, Lord’s Cricket Ground, London

EWi system designer Alsecco chose the Ecomin 400 to address design the challenges of this prestigious scheme. The system was applied to the external facades of the concession pods on the new stands.

The design incorporates fluted white ceramic tiles that create a striking approach to the spectator stands, practice nets and playing area. The ceramic walls of the new stands, positioned either side of the media centre, needed to completely match the curvature of the white roofs.

The structural steel framing (SFS) system was faceted so the roof lines had to provide the datum for the exterior walls. Using string lines ensured exact positioning.

Lamella mineral wool boards were used to convert the faceted cement particle sheathing boards into a smooth curve. The completed Ecomin 400 system curves to complement the white roof coverings and architectural ironmongery, contrasting with the grey flashings and wall panels.

EWI is a technology employing insulation boards fixed to the sheathing layer of new-build schemes built with steel framing or with a concrete frame with SSF infill or to masonry walls in a refurbishment setting.

Beyond these common construction types, other less prominent building methods, such as timber frame, insulated concrete formwork and offsite construction, can also benefit from the use of EWI.

Systems are finished with high-grade decorative coatings or brick slip finishes.

INCA is inviting any architects involved in a scheme using EWI to contact the system designer or installer to consider submitting entries for next year’s awards.
