In addition, it performs very well less than significant-temperature disorders and delivers purely natural vapour permeability, helping prevent trapped dampness.
five. Spray Polyurethane Foam (SPF)
SPF insulation generates a seamless, monolithic layer that adheres on to the roof deck. it provides outstanding air sealing, humidity safety, and thermal resistance.
-
cuts down air leakage and warmth transfer.
-
functions as both of those insulation and waterproofing in a single application.
even so, it involves proficient applicators and strict climatic conditions all through installation, which often can have an effect on challenge scheduling.
Flat Roof Insulation layout Approaches
powerful insulation isn’t almost material variety — it’s regarding how Every layer interacts inside the roofing assembly. Canadian business roofs usually use 1 of these 3 style methods:
1. traditional Roof program
-
Insulation is mounted under the water-resistant membrane.
-
The membrane is completely exposed to The weather, which might decrease its lifespan if not adequately safeguarded.
-
appropriate for structures that prioritize insulation Price tag-performance above rooftop accessibility.
2. Inverted Roof process (safeguarded Membrane Roof or PMR)
-
The water resistant membrane lies beneath the insulation, guarding it from temperature fluctuations and UV exposure.
-
perfect for Canada’s Serious climates and for roofs that come with pavers, terraces, or mechanical walkways.
-
works by using dense, humidity-resistant insulation like XPS.
three. Hybrid Roof procedure
-
