In addition it performs nicely below substantial-temperature conditions and delivers all-natural vapour permeability, supporting reduce trapped moisture.
5. Spray Polyurethane Foam (SPF)
SPF insulation makes a seamless, monolithic layer that adheres straight to the roof deck. It offers fantastic air sealing, humidity protection, and thermal resistance.
-
cuts down air leakage and warmth transfer.
-
functions as each insulation and waterproofing in one application.
However, it calls for skilled applicators and demanding climatic conditions all through set up, which often can affect venture scheduling.
Flat Roof Insulation layout Approaches
efficient insulation isn’t just about materials collection — it’s about how Every layer interacts in the roofing assembly. Canadian business roofs usually use a single of those three layout devices:
1. typical Roof procedure
-
Insulation is set up below the water-proof membrane.
-
The membrane is absolutely exposed to The weather, which can cut down its lifespan Otherwise correctly protected.
-
ideal for buildings that prioritize insulation Charge-performance in excess of rooftop accessibility.
two. Inverted Roof System (guarded Membrane Roof or PMR)
-
The watertight membrane lies beneath the insulation, shielding it from temperature fluctuations and UV exposure.
-
perfect for Canada’s Excessive climates and for roofs which include pavers, terraces, or mechanical walkways.
-
employs dense, dampness-resistant insulation like XPS.
three. Hybrid Roof method
-
