It also performs very well underneath high-temperature ailments and supplies all-natural vapour permeability, serving to reduce trapped humidity.
five. Spray Polyurethane Foam (SPF)
SPF insulation generates a seamless, monolithic layer that adheres straight to the roof deck. it provides excellent air sealing, humidity protection, and thermal resistance.
-
lowers air leakage and warmth transfer.
-
functions as the two insulation and waterproofing in a single application.
However, it necessitates qualified applicators and rigorous weather conditions through set up, which often can have an effect on project scheduling.
Flat Roof Insulation structure ways
productive insulation isn’t nearly material choice — it’s regarding how Each individual layer interacts throughout the roofing assembly. Canadian industrial roofs generally use one particular of these three design and style units:
one. Conventional Roof program
-
Insulation is mounted beneath the waterproof membrane.
-
The membrane is fully exposed to the elements, which might cut down its lifespan if not thoroughly shielded.
-
ideal for buildings that prioritize insulation Price-effectiveness over rooftop accessibility.
2. Inverted Roof process (secured Membrane Roof or PMR)
-
The water-resistant membrane lies beneath the insulation, safeguarding it from temperature fluctuations and UV exposure.
-
perfect for Canada’s Excessive climates and for roofs which include pavers, terraces, or mechanical walkways.
-
Uses dense, humidity-resistant insulation like XPS.
three. Hybrid Roof process
-
