SPF insulation produces a seamless, monolithic layer that adheres directly to the roof deck. it provides outstanding air sealing, moisture safety, and thermal resistance.
-
lessens air leakage and heat transfer.
-
functions as the two insulation and waterproofing in one application.
having said that, it necessitates proficient applicators and demanding climatic conditions throughout set up, which can influence challenge scheduling.
Flat Roof Insulation structure methods
productive insulation isn’t nearly material collection — it’s regarding how Each individual layer interacts throughout the roofing assembly. Canadian commercial roofs usually use a person of those three structure programs:
one. typical Roof program
-
Insulation is mounted underneath the water resistant membrane.
-
The membrane is entirely subjected to the elements, which often can decrease its lifespan if not effectively safeguarded.
-
ideal for buildings that prioritize insulation Charge-performance more than rooftop accessibility.
two. Inverted Roof procedure (Protected Membrane Roof or PMR)
-
The waterproof membrane lies beneath the insulation, preserving it from temperature fluctuations and UV exposure.
-
perfect for Canada’s Excessive climates and for roofs that come with pavers, terraces, or mechanical walkways.
-
employs dense, moisture-resistant insulation like XPS.
