minimizes air leakage and warmth transfer.
-
functions as both of those insulation and waterproofing in a single software.
even so, it requires experienced applicators and stringent weather conditions through installation, which can have an impact on project scheduling.
Flat Roof Insulation design and style techniques
helpful insulation isn’t pretty much materials variety — it’s about how Every layer interacts within the roofing assembly. Canadian commercial roofs normally use a single of these three style programs:
one. typical Roof method
-
Insulation is set up down below the water-proof membrane.
-
The membrane is completely subjected to The weather, which often can minimize its lifespan if not correctly safeguarded.
-
well suited for buildings that prioritize insulation Value-performance about rooftop accessibility.
two. Inverted Roof process (Protected Membrane Roof or PMR)
-
The water-resistant membrane lies beneath the insulation, preserving it from temperature fluctuations and UV publicity.
-
perfect for Canada’s extreme climates and for roofs that come with pavers, terraces, or mechanical walkways.
