four. Mineral Wool (Rockwool)
Mineral wool is prized for its fire resistance and audio insulation properties. It’s specially suited to buildings where hearth codes are stringent or wherever sound reduction is very important, for instance industrial vegetation or hospitals.
In addition it performs nicely beneath significant-temperature conditions and offers organic vapour permeability, helping reduce trapped humidity.
5. Spray Polyurethane Foam (SPF)
SPF insulation produces a seamless, monolithic layer that adheres directly to the roof deck. It offers excellent air sealing, moisture security, and thermal resistance.
-
Reduces air leakage and heat transfer.
-
functions as both of those insulation and waterproofing in one application.
having said that, it needs competent applicators and stringent climatic conditions throughout installation, which could affect challenge scheduling.
Flat Roof Insulation layout methods
successful insulation isn’t nearly material assortment — it’s about how Every single layer interacts throughout the roofing assembly. Canadian industrial roofs typically use 1 of those three style units:
one. regular Roof procedure
-
Insulation is mounted under the water-resistant membrane.
-
The membrane is absolutely subjected to The weather, which may lessen its lifespan if not thoroughly shielded.
-
Suitable for structures that prioritize insulation cost-efficiency around rooftop accessibility.
two. Inverted Roof procedure (shielded Membrane Roof or PMR)
-
The waterproof membrane lies beneath the insulation, preserving it from temperature fluctuations and UV exposure.
-
Ideal for Canada’s extreme climates and for roofs that include pavers, terraces, or mechanical walkways.
-
works by using dense, moisture-resistant insulation like XPS.
3. Hybrid Roof program
-
