Furthermore, it performs well below superior-temperature problems and provides all-natural vapour permeability, aiding reduce trapped humidity.
five. Spray Polyurethane Foam (SPF)
SPF insulation results in a seamless, monolithic layer that adheres directly to the roof deck. It offers fantastic air sealing, moisture safety, and thermal resistance.
-
lowers air leakage and warmth transfer.
-
Acts as both equally insulation and waterproofing in one application.
nevertheless, it demands competent applicators and strict weather conditions all through set up, which may have an impact on undertaking scheduling.
Flat Roof Insulation design and style techniques
successful insulation isn’t nearly materials collection — it’s regarding how Every layer interacts in the roofing assembly. Canadian business roofs usually use just one of such three style and design devices:
one. typical Roof method
-
Insulation is installed under the water resistant membrane.
-
The membrane is fully subjected to the elements, which can minimize its lifespan if not thoroughly shielded.
-
appropriate for structures that prioritize insulation Value-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.
-
Ideal for Canada’s extreme climates and for roofs that come with pavers, terraces, or mechanical walkways.
-
works by using dense, humidity-resistant insulation like XPS.
3. Hybrid Roof method
