INCA Case Study: Buckingham House, High Wycombe

Buckingham House is a new 85-home Inland Homes development in the heart of High Wycombe, completed in February 2022, it is also the latest high rise development in the South East to feature brick finish as its external façade. Underpinned with an innovative non combustible external wall insulation system, SPSenvirowall has participated in creating a fire safe and thermally efficient building for residents in High Wycombe.

The façade, installed by Stanmore on behalf of Inland Homes, combined both Cavity System 2 and SpeedySlips delivering results which are outstanding and produce an intriguing and engaging brickwork façade.
To reach the highest standard of fire safety for the external cladding, SPSenvirowall was approached to supply its Cavity System 2 solution for its A2-s1, d0 fire-rated classification in accordance with BS EN13501-1. SPSenvirowall’s Cavity System 2 consist of EuroClass A1 components which are mechanically fixed back to the inner sheathing board to create the designed cavity width when applying a secondary 12mm A1 sheathing board and 130mm mineral wool insulation, with the addition of SpeedySlips to create the attractive façade.

Flexible brick slips are frequently being chosen for external facades to improve the aesthetics of the building and are a quick and cost-effective material for the client. SpeedySlip was chosen as it is both flexible and lightweight, which measures only 4-6mm thick and can easily be fixed to basecoat renders with our ultra high flexible bonding adhesive. Furthermore, it has obtained undertaken extensive certification with a number of accreditation bodies such as BBA, KIWA and Bopas. These benefits make SpeedySlip not only suitable for cladding new structures but are increasingly being used to regenerate buildings.

The façade in part also included a topcoat of Flexisil, a combination of an acrylic base with silicone enhanced additives offering the flexibility and extensive colour choice of acrylic with the water repellency and enhanced cleansing properties of silicone. The white textured topcoat included both 3mm and 1.5mm grain size.
