Compatible accessories are important to ensure that a Whistler roof achieves maximum life. Fasteners and flashings should always be made from material designed to last as long as the Whistler roof. Incompatible or substandard accessories can lead to failure of one or more components.  Insulation should not be exposed where it will be continually wet and in contact with the underside of roof panels.

POLYETHYLENE FOAM 
The Super Insulation Material

Polyethylene Foam is a non - cross linked closed cell.  Polyethylene foam insulation made from the extrusion of low-density polyethylene resins.  The closed cell structure of polyethylene foam makes it heat proof,  waterproof and sound proof,  non- fibrous and chemical resistant over a long period of time.  It is the superior insulation material for buildings because it is non-toxic, lightweight, and easy to install.
