Sustainable waterproofing and insulation – The Foamglas Specification

September 8, 2021

This podium deck sits above a habitable room that required additional insulation to better deal with heat loss and potential condensation risks.


The architect requested a more sustainable option to XPS. Delta Membrane Systems Ltd Delta Glass Roof Board is a Foamglas innovation that is made from 100% recycled glass and has high compressive strength. Installed as part of a waterproofing system its a perfect alternative to the XPS insulation.


Installed correctly, the insulation raises the dew point below it so reduces the internal condensation risks, keeps the internal environment warm and therefore uses less energy to heat. Additionally the insulation forms part of the waterproofing system above to keep the deck dry.


We love keeping up to date with new technologies, especially green initiatives like this.
