minimizes air leakage and heat transfer.
-
Acts as both equally insulation and waterproofing in one application.
However, it demands experienced applicators and rigorous weather conditions for the duration of set up, which could have an affect on job scheduling.
Flat Roof Insulation Design Approaches
productive insulation isn’t almost material variety — it’s regarding how Each individual layer interacts in the roofing assembly. Canadian business roofs commonly use just one of these 3 layout methods:
1. typical Roof technique
-
Insulation is set up under the watertight membrane.
-
The membrane is completely subjected to the elements, which may reduce its lifespan if not thoroughly guarded.
-
suited to buildings that prioritize insulation Price-efficiency around rooftop accessibility.
2. Inverted Roof process (safeguarded Membrane Roof or PMR)
-
The water-resistant membrane lies beneath the insulation, shielding it from temperature fluctuations and UV publicity.
-
perfect for Canada’s extreme climates and for roofs that come with pavers, terraces, or mechanical walkways.
