SPF insulation makes a seamless, monolithic layer that adheres straight to the roof deck. It offers outstanding air sealing, dampness protection, and thermal resistance.
-
minimizes air leakage and warmth transfer.
-
Acts as equally insulation and waterproofing in one software.
having said that, it calls for competent applicators and strict weather conditions during set up, that may have an affect on venture scheduling.
Flat Roof Insulation structure strategies
successful insulation isn’t just about product range — it’s about how Every layer interacts in the roofing assembly. Canadian business roofs normally use 1 of those 3 style methods:
1. common Roof procedure
-
Insulation is put in down below the water-resistant membrane.
-
The membrane is thoroughly subjected to The weather, which could cut down its lifespan Otherwise appropriately shielded.
-
ideal for properties that prioritize insulation Value-performance more than rooftop accessibility.
two. Inverted Roof technique (Protected Membrane Roof or PMR)
-
The water-resistant membrane lies beneath the insulation, guarding it from temperature fluctuations and UV exposure.
-
Ideal for Canada’s Extraordinary climates and for roofs that come with pavers, terraces, or mechanical walkways.
-
takes advantage of dense, humidity-resistant insulation like XPS.
three. Hybrid Roof process
-
