Environmental Consideration
Contains no unbonded fire retardants like HBCD ( Hexabromocyclododecane) which has been banned in Canada and is a toxic substance of high con-
cern with the US EPA.
Highlights
Blue XPS core is 100% waterproof and remains fully functional even after partial damage- specially engineered for 100% consistency of its closed-cell
structure. The particular cell structure design ensures compression strength where it is needed, internal waterproofness and an easy cut experience.
wedi product surfaces include specially designed and manufactured fiberglass mesh, fully embedded in the coating. It won‘t break, and it offers a
structure with texture for perfect tile adhesion. The strong backing properties of the panels start with the mesh surface coating.
wedi’s foam-based products are made with extrusion agents in compliance with the Montreal Protocol, helping to reduce Global Warming Potential
(GWP). The foam-based products are made from 25% recycled content.
wedi does not compromise safety or composition and provides safe fire behavior and protection. wedi uses consistent levels of fully polymeric bonded
flame retardant (PFR) that does not release over time. wedi products meet international standards such as REACH and the UN’s Stockholm Convention
Protocols. The foam is precisely milled and cut to produce tile underlayment s urfaces with absolutely perfect dimensions. All milling waste is recycled.
wedi joint sealants are Polyisocyanates and PVC free and are zero VOC sealants.
