What's more, it performs perfectly underneath substantial-temperature problems and provides all-natural vapour permeability, assisting prevent trapped dampness.
5. Spray Polyurethane Foam (SPF)
SPF insulation results in a seamless, monolithic layer that adheres directly to the roof deck. It offers outstanding air sealing, humidity security, and thermal resistance.
-
cuts down air leakage and warmth transfer.
-
Acts as both of those insulation and waterproofing in one application.
nonetheless, it requires qualified applicators and rigid climatic conditions through installation, that may affect venture scheduling.
Flat Roof Insulation style and design strategies
helpful insulation isn’t just about materials range — it’s about how Just about every layer interacts in the roofing assembly. Canadian business roofs typically use one particular of those three layout programs:
1. Conventional Roof technique
-
Insulation is put in down below the water resistant membrane.
-
The membrane is entirely subjected to The weather, that may reduce its lifespan Otherwise adequately protected.
-
Suitable for buildings that prioritize insulation Price tag-performance about rooftop accessibility.
two. Inverted Roof process (Protected Membrane Roof or PMR)
-
The water-resistant membrane lies beneath the insulation, shielding it from temperature fluctuations and UV exposure.
-
perfect for Canada’s Severe climates and for roofs which include pavers, terraces, or mechanical walkways.
