SPF insulation generates a seamless, monolithic layer that adheres straight to the roof deck. it provides fantastic air sealing, dampness protection, and thermal resistance.
-
Reduces air leakage and warmth transfer.
-
Acts as both of those insulation and waterproofing in one software.
nevertheless, it demands expert applicators and strict climatic conditions throughout installation, that may impact project scheduling.
Flat Roof Insulation layout methods
efficient insulation isn’t almost material range — it’s about how Each and every layer interacts throughout the roofing assembly. Canadian professional roofs usually use a person of these three layout systems:
one. Conventional Roof procedure
-
Insulation is put in underneath the water-resistant membrane.
-
The membrane is completely subjected to The weather, which can minimize its lifespan Otherwise thoroughly guarded.
-
well suited for buildings that prioritize insulation Charge-effectiveness above rooftop accessibility.
2. Inverted Roof procedure (Protected Membrane Roof or PMR)
-
The water resistant membrane lies beneath the insulation, shielding it from temperature fluctuations and UV publicity.
-
perfect for Canada’s Severe climates and for roofs that come with pavers, terraces, or mechanical walkways.
