In addition it performs nicely underneath higher-temperature circumstances and presents organic vapour permeability, supporting reduce trapped dampness.
5. Spray Polyurethane Foam (SPF)
SPF insulation generates a seamless, monolithic layer that adheres straight to the roof deck. it provides outstanding air sealing, dampness safety, and thermal resistance.
-
lowers air leakage and warmth transfer.
-
Acts as each insulation and waterproofing in one software.
having said that, it requires skilled applicators and strict climatic conditions throughout installation, which may influence undertaking scheduling.
Flat Roof Insulation style and design ways
Effective insulation isn’t almost product collection — it’s about how Every single layer interacts in the roofing assembly. Canadian business roofs commonly use a person of these 3 style and design techniques:
1. traditional Roof System
-
Insulation is put in under the water resistant membrane.
-
The membrane is absolutely subjected to The weather, that may lower its lifespan Otherwise effectively guarded.
-
appropriate for structures that prioritize insulation Price tag-efficiency above rooftop accessibility.
two. Inverted Roof procedure (secured Membrane Roof or PMR)
-
The waterproof membrane lies beneath the insulation, safeguarding it from temperature fluctuations and UV publicity.
-
