2 Ply Modified Bitumen - Built Up Roofing
This article provides a quick reference for our tried-and-true: one of the best, long-lasting and most durable commercial flat roofing systems available for the Northern climate.
This roof assembly is designed to be a completely 'flameless' installation - meaning no open flame is present during installation, dramatically improving safety. Instead of a torch, specialized high temperature heatguns are used to achieve the same uniform result, fusing the plies together as one monolithic membrane. The heatwelding process is a reliable technique that is quickly becoming the industry standard for most respected flat roofing systems.
The built-up roof system comprises of the following products:
Adhesive Primer
Vapour Barrier
Insulation Board
Glass Mat Support Panels
SBS Modified Bitumen BASE (Ply 1)
SBS Modified Bitumen CAP (Ply 2)
Note: The products linked above are manufactured by Soprema. Other manufacturers make similar like-kind products which may be substituted to achieve the same result - it really depends on the specific application at hand.
The system may be adhered or mechanically fastened - every application will vary.
