cuts down air leakage and warmth transfer.
-
functions as the two insulation and waterproofing in a single software.
However, it requires skilled applicators and stringent climatic conditions all through installation, which might have an impact on task scheduling.
Flat Roof Insulation Design strategies
helpful insulation isn’t just about substance selection — it’s regarding how Each and every layer interacts throughout the roofing assembly. Canadian professional roofs typically use a person of these three style and design devices:
one. standard Roof method
-
Insulation is installed beneath the water-proof membrane.
-
The membrane is totally exposed to the elements, which can cut down its lifespan if not appropriately safeguarded.
-
well suited for properties that prioritize insulation cost-effectiveness more than rooftop accessibility.
two. Inverted Roof procedure (secured Membrane Roof or PMR)
-
The water resistant membrane lies beneath the insulation, preserving it from temperature fluctuations and UV exposure.
-
perfect for Canada’s Excessive climates and for roofs that come with pavers, terraces, or mechanical walkways.
-
Uses dense, moisture-resistant insulation like XPS.
3. Hybrid Roof process
-
