SPSEnvirowall

The British Board of Agrément (BBA) approved SPSenvirowall has supplied insulation in a mixed development of affordable homes in Bristol.

The mixed development, situated near Junction 3 of the M32 in Bristol, comprises of 59 affordable homes that were constructed with sustainable, energy saving materials. The differing aesthetic appearances throughout this mixed development meant that there were a number of substrate changes that required a variety of BBA approved SPSenvirowall render solutions and finishes.

Differences between the 59 homes included aspects such as feature curve walls and waving bulkheads, as well as interchanging colours between renders installed onto varying substrates such including: timber frame, chear concrete walls, blockwork and secondary steel frame. The contractors achieved a high quality finish by using the SPSenvirowall TS Rail and Rendaclad, which were predominantly developed for new build applications and incorporate a draining cavity, to sheathing board and render only systems.

SPSenvirowall products have been rigorously tested and used throughout UK and continental Europe for over 40 years, ensuring that they are truly tried and tested. The insulation systems not only provide a decorative uplift to old buildings, but also greatly improve the thermal efficiency of the building thus helping to cut CO2 emissions.
