four. Mineral Wool (Rockwool)
Mineral wool is prized for its fire resistance and seem insulation Qualities. It’s specifically suited to buildings exactly where fire codes are stringent or where sounds reduction is essential, for instance industrial vegetation or hospitals.
In addition it performs nicely less than higher-temperature disorders and offers organic vapour permeability, supporting reduce trapped dampness.
5. Spray Polyurethane Foam (SPF)
SPF insulation results in a seamless, monolithic layer that adheres straight to the roof deck. It offers superb air sealing, moisture security, and thermal resistance.
-
lowers air leakage and warmth transfer.
-
functions as equally insulation and waterproofing in a single software.
on the other hand, it demands experienced applicators and rigid weather conditions throughout installation, that may affect task scheduling.
Flat Roof Insulation layout methods
productive insulation isn’t nearly material collection — it’s about how Every single layer interacts in the roofing assembly. Canadian business roofs ordinarily use one of those 3 design devices:
1. regular Roof method
-
Insulation is installed underneath the water resistant membrane.
-
The membrane is thoroughly exposed to The weather, which might reduce its lifespan if not adequately secured.
-
appropriate for structures that prioritize insulation Charge-performance around rooftop accessibility.
2. Inverted Roof technique (secured Membrane Roof or PMR)
-
The waterproof membrane lies beneath the insulation, safeguarding it from temperature fluctuations and UV publicity.
-
perfect for Canada’s Serious climates and for roofs which include pavers, terraces, or mechanical walkways.
-
utilizes dense, moisture-resistant insulation like XPS.
