-
cuts down air leakage and heat transfer.
-
functions as equally insulation and waterproofing in one software.
nonetheless, it requires experienced applicators and stringent climatic conditions during installation, that may have an impact on venture scheduling.
Flat Roof Insulation style strategies
successful insulation isn’t just about materials collection — it’s about how Each individual layer interacts inside the roofing assembly. Canadian commercial roofs normally use just one of those 3 layout systems:
1. common Roof program
-
Insulation is set up below the water-resistant membrane.
-
The membrane is fully subjected to The weather, which often can reduce its lifespan if not effectively guarded.
-
ideal for buildings that prioritize insulation Price-effectiveness over rooftop accessibility.
two. Inverted Roof procedure (safeguarded Membrane Roof or PMR)
-
The watertight membrane lies beneath the insulation, guarding it from temperature fluctuations and UV publicity.
-
Ideal for Canada’s Intense climates and for roofs which include pavers, terraces, or mechanical walkways.
-
makes use of dense, humidity-resistant insulation like XPS.
three. Hybrid Roof process
-
