SPF insulation makes a seamless, monolithic layer that adheres on to the roof deck. it provides excellent air sealing, moisture safety, and thermal resistance.
-
lessens air leakage and heat transfer.
-
Acts as equally insulation and waterproofing in a single application.
even so, it involves experienced applicators and rigid weather conditions in the course of set up, that may impact job scheduling.
Flat Roof Insulation style and design techniques
successful insulation isn’t almost substance collection — it’s about how Each and every layer interacts inside the roofing assembly. Canadian industrial roofs generally use 1 of such three layout techniques:
1. standard Roof process
-
Insulation is put in under the waterproof membrane.
-
The membrane is absolutely exposed to the elements, which may decrease its lifespan if not properly safeguarded.
-
Suitable for buildings that prioritize insulation Price tag-performance above rooftop accessibility.
2. Inverted Roof technique (Protected Membrane Roof or PMR)
-
The water resistant membrane lies beneath the insulation, protecting it from temperature fluctuations and UV exposure.
-
