lessens air leakage and warmth transfer.
-
functions as each insulation and waterproofing in a single software.
on the other hand, it requires proficient applicators and rigorous weather conditions during set up, that may impact project scheduling.
Flat Roof Insulation layout techniques
Effective insulation isn’t pretty much material range — it’s regarding how each layer interacts throughout the roofing assembly. Canadian industrial roofs ordinarily use just one of these 3 layout programs:
1. regular Roof System
-
Insulation is installed below the water resistant membrane.
-
The membrane is totally subjected to The weather, which might decrease its lifespan if not appropriately guarded.
-
ideal for buildings that prioritize insulation Value-performance above rooftop accessibility.
2. Inverted Roof program (Protected Membrane Roof or PMR)
-
The water-resistant membrane lies beneath the insulation, shielding it from temperature fluctuations and UV publicity.
-
Ideal for Canada’s extreme climates and for roofs that come with pavers, terraces, or mechanical walkways.
-
Uses dense, dampness-resistant insulation like XPS.
3. Hybrid Roof program
