-
functions as both of those insulation and waterproofing in one application.
nonetheless, it calls for skilled applicators and rigorous weather conditions in the course of installation, which might have an impact on task scheduling.
Flat Roof Insulation structure techniques
Effective insulation isn’t pretty much substance variety — it’s regarding how Just about every layer interacts in the roofing assembly. Canadian professional roofs normally use one of these 3 design units:
1. standard Roof System
-
Insulation is set up beneath the water-resistant membrane.
-
The membrane is completely exposed to The weather, which might cut down its lifespan if not effectively shielded.
-
appropriate for buildings that prioritize insulation cost-performance around rooftop accessibility.
2. Inverted Roof procedure (shielded Membrane Roof or PMR)
-
The waterproof membrane lies beneath the insulation, guarding it from temperature fluctuations and UV exposure.
-
Ideal for Canada’s Severe climates and for roofs which include pavers, terraces, or mechanical walkways.
-
makes use of dense, dampness-resistant insulation like XPS.
3. Hybrid Roof process
