-
functions as equally insulation and waterproofing in one application.
on the other hand, it demands qualified applicators and rigorous climatic conditions in the course of set up, that may influence project scheduling.
Flat Roof Insulation style and design Approaches
successful insulation isn’t almost materials range — it’s about how Every layer interacts within the roofing assembly. Canadian industrial roofs ordinarily use one particular of these three design and style devices:
one. common Roof method
-
Insulation is mounted below the water-resistant membrane.
-
The membrane is fully exposed to The weather, which can decrease its lifespan Otherwise appropriately safeguarded.
-
suited to buildings that prioritize insulation Charge-effectiveness more than rooftop accessibility.
two. Inverted Roof technique (secured Membrane Roof or PMR)
-
The water-resistant membrane lies beneath the insulation, safeguarding it from temperature fluctuations and UV publicity.
-
perfect for Canada’s Serious climates and for roofs which include pavers, terraces, or mechanical walkways.
-
employs dense, dampness-resistant insulation like XPS.
3. Hybrid Roof procedure
-
