SPF insulation creates a seamless, monolithic layer that adheres straight to the roof deck. It offers great air sealing, dampness security, and thermal resistance.
-
lessens air leakage and heat transfer.
-
functions as both of those insulation and waterproofing in one application.
nonetheless, it calls for skilled applicators and stringent climatic conditions for the duration of installation, which could influence task scheduling.
Flat Roof Insulation layout strategies
powerful insulation isn’t pretty much materials selection — it’s about how each layer interacts inside the roofing assembly. Canadian industrial roofs commonly use just one of such 3 layout techniques:
one. regular Roof method
-
Insulation is set up below the waterproof membrane.
-
The membrane is totally subjected to the elements, which might cut down its lifespan if not effectively secured.
-
ideal for buildings that prioritize insulation Price tag-efficiency over rooftop accessibility.
2. Inverted Roof procedure (shielded Membrane Roof or PMR)
-
The watertight membrane lies beneath the insulation, preserving it from temperature fluctuations and UV publicity.
-
perfect for Canada’s Intense climates and for roofs which include pavers, terraces, or mechanical walkways.
