are available in two categories: Rigid
prefab boards of different densities
and sprayed in situ for seamless application.
Rigid roof insulation boards consist of PUR
–Polyurethane and PIR-Polyisocyanurate foam
boards laminated with different types
of facing to suit the need of the waterproofing
Sprayed polyurethane foam is
a foamed plastic material produced by mixing two
part chemical liquid – poly-isocyanurate
and polyol that is spray applied by airless spray
method to decks.
The two component mixture reacts chemically and
immediately expands when applied through specialized
equipments to form closed cell foam. Foam rises
and sets into a solid and a skin forms on the
surface providing thermal and water resistant
surface. Liquid applied protective elastomeric
paints are recommended on spray applied polyurethane
to protect from UV degradation.
