External Wall Insulation (EWI) Contractor

CDL Rendering installs external wall insulation systems for new-build and retrofit commercial projects, including housing association planned works, across Milton Keynes, Buckinghamshire, Bedfordshire, Northamptonshire, Hertfordshire and Oxfordshire.

EWI for new build and retrofit

Insulated render systems to achieve specified U-values on new-build envelopes.

Fire safety and system compliance

We install only the tested system as specified — insulation type, fixings, fire breaks and render build-up — without substitution. Where building height or use requires non-combustible materials (e.g. mineral wool insulation with a suitable reaction-to-fire classification), we work to the designer's specification and the system manufacturer's documentation. Installation records support the golden-thread information the client and principal designer need. We are approved applicators for EWI Pro systems.
