-
Acts as both of those insulation and waterproofing in one application.
even so, it necessitates skilled applicators and demanding climatic conditions for the duration of set up, which often can affect venture scheduling.
Flat Roof Insulation design and style Approaches
Effective insulation isn’t almost materials range — it’s regarding how Every single layer interacts in the roofing assembly. Canadian professional roofs usually use one of these a few design systems:
one. traditional Roof technique
-
Insulation is set up down below the watertight membrane.
-
The membrane is absolutely subjected to the elements, which could cut down its lifespan if not effectively guarded.
-
Suitable for structures that prioritize insulation Value-performance over rooftop accessibility.
two. Inverted Roof method (Protected Membrane Roof or PMR)
-
The watertight membrane lies beneath the insulation, defending it from temperature fluctuations and UV exposure.
-
Ideal for Canada’s Excessive climates and for roofs that include pavers, terraces, or mechanical walkways.
-
utilizes dense, humidity-resistant insulation like XPS.
three. Hybrid Roof process
-
