-
decreases air leakage and warmth transfer.
-
Acts as equally insulation and waterproofing in one application.
on the other hand, it needs competent applicators and rigorous climatic conditions during set up, which could influence venture scheduling.
Flat Roof Insulation Design Approaches
powerful insulation isn’t almost content collection — it’s about how Each and every layer interacts throughout the roofing assembly. Canadian business roofs generally use one particular of these 3 style and design systems:
1. typical Roof program
-
Insulation is put in underneath the water-proof membrane.
-
The membrane is thoroughly exposed to The weather, which can decrease its lifespan if not correctly secured.
-
appropriate for buildings that prioritize insulation Price-efficiency more than rooftop accessibility.
two. Inverted Roof process (shielded Membrane Roof or PMR)
-
The water resistant membrane lies beneath the insulation, defending it from temperature fluctuations and UV exposure.
-
perfect for Canada’s Intense climates and for roofs that come with pavers, terraces, or mechanical walkways.
-
employs dense, humidity-resistant insulation like XPS.
