4. Mineral Wool (Rockwool)
Mineral wool is prized for its fire resistance and sound insulation Homes. It’s especially suited to properties where fire codes are stringent or exactly where sound reduction is important, for instance industrial crops or hospitals.
In addition, it performs very well underneath large-temperature ailments and supplies natural vapour permeability, serving to avoid trapped humidity.
five. Spray Polyurethane Foam (SPF)
SPF insulation creates a seamless, monolithic layer that adheres straight to the roof deck. It offers superb air sealing, humidity protection, and thermal resistance.
-
lessens air leakage and heat transfer.
-
Acts as both insulation and waterproofing in one software.
However, it involves skilled applicators and rigid climatic conditions during set up, which may affect venture scheduling.
Flat Roof Insulation layout ways
powerful insulation isn’t just about substance variety — it’s regarding how Every layer interacts in the roofing assembly. Canadian commercial roofs normally use one of such 3 design systems:
1. regular Roof procedure
-
Insulation is set up underneath the watertight membrane.
-
The membrane is absolutely exposed to The weather, which might lower its lifespan if not correctly secured.
-
Suitable for properties that prioritize insulation Expense-performance more than rooftop accessibility.
2. Inverted Roof System (guarded Membrane Roof or PMR)
-
The watertight membrane lies beneath the insulation, guarding it from temperature fluctuations and UV publicity.
-
Ideal for Canada’s Intense climates and for roofs that come with pavers, terraces, or mechanical walkways.
-
makes use of dense, moisture-resistant insulation like XPS.
three. Hybrid Roof method
-
