minimizes air leakage and heat transfer.
-
Acts as both of those insulation and waterproofing in a single application.
nevertheless, it involves experienced applicators and stringent weather conditions in the course of set up, which often can influence job scheduling.
Flat Roof Insulation Design strategies
successful insulation isn’t almost product range — it’s about how Every layer interacts inside the roofing assembly. Canadian commercial roofs typically use one of such 3 design and style programs:
1. traditional Roof process
-
Insulation is mounted under the water-resistant membrane.
-
The membrane is fully subjected to the elements, which might reduce its lifespan Otherwise adequately safeguarded.
-
Suitable for properties that prioritize insulation Expense-effectiveness above rooftop accessibility.
two. Inverted Roof procedure (guarded Membrane Roof or PMR)
-
The water-proof membrane lies beneath the insulation, shielding it from temperature fluctuations and UV exposure.
