SPSenvirowall’s Journey to BOPAS Accreditation


PSenvirowall, a UK leading supplier of external wall insulation, render and facades, has secured BOPAS

(Buildoffsite Property Assurance Scheme) accreditation for its innovative, rain screen cladding, RendaClad for the new build and offsite construction industry. RendaClad was developed for applying a non-structural and seamless rendered rain screen system to a timber-framed substrate. It replaces the need to build a structural masonry outer leaf that is finished with

low-performance cementitious renders. RendaClad is a full facade system made up

of many carefully selected components which have been rigorously tested and as an entire system makes up one of a very few BBA approved systems of its type which provides the reassurance that it will perform over the long term. The system ensures a fully ventilated and

drained cavity is maintained within the wall structure, meeting the requirements of the NHBC and TRADA. The system can be

applied to any wall structure, lightweight steel frame or masonry construction. SPSenvirowall is delighted that RendaClad

is the first and currently only proprietary solution which has undergone the rigorous BOPAS accreditation process designed to give lenders and surveyors the assurance of the building materials utilised within a development. This has provided confidence to the market that the innovative concept has a minimum life expectancy of 60-years. This accreditation will allow SPSenvirowall

to deliver its RendaClad system to offsite and modular developments, enabling the supply of a greater range of projects while providing the assurance required to satisfy mortgage lenders and their surveyors, meaning that the RendaClad system will last for a minimum of two mortgage cycles With the challenges brought by the

government to build 250,000 homes per year, the demand for innovative or non-traditional methods of construction to replace poor quality and conventionally constructed homes has never been greater. BOPAS accreditation assures lenders,

funders, valuers and purchasers that homes built from non-traditional means will be durable and deliver the quality required by the industry.
