SPF insulation generates a seamless, monolithic layer that adheres straight to the roof deck. it provides exceptional air sealing, humidity protection, and thermal resistance.

Reduces air leakage and warmth transfer.
functions as both equally insulation and waterproofing in a single application.

even so, it needs competent applicators and strict weather conditions for the duration of installation, which may have an effect on venture scheduling.

Flat Roof Insulation layout Approaches

Effective insulation isn’t pretty much substance variety — it’s about how Every layer interacts within the roofing assembly. Canadian commercial roofs typically use just one of such three design and style units:

1. traditional Roof program

Insulation is put in under the waterproof membrane.
The membrane is entirely exposed to the elements, which may reduce its lifespan if not appropriately shielded.
appropriate for properties that prioritize insulation cost-effectiveness about rooftop accessibility.

two. Inverted Roof method (Protected Membrane Roof or PMR)

The water-resistant membrane lies beneath the insulation, safeguarding it from temperature fluctuations and UV exposure.
perfect for Canada’s Excessive climates and for roofs which include pavers, terraces, or mechanical walkways.
