Mineral wool is prized for its fire resistance and seem insulation Attributes. It’s particularly suited to structures where fireplace codes are stringent or the place sound reduction is crucial, such as industrial plants or hospitals.
It also performs well less than high-temperature problems and offers purely natural vapour permeability, supporting avert trapped moisture.
5. Spray Polyurethane Foam (SPF)
SPF insulation produces a seamless, monolithic layer that adheres straight to the roof deck. it provides great air sealing, moisture defense, and thermal resistance.
-
lowers air leakage and heat transfer.
-
functions as both insulation and waterproofing in a single application.
nevertheless, it calls for expert applicators and rigid weather conditions all through set up, that may have an effect on venture scheduling.
Flat Roof Insulation style and design strategies
helpful insulation isn’t just about material selection — it’s about how Just about every layer interacts within the roofing assembly. Canadian professional roofs normally use one of those 3 structure devices:
one. regular Roof process
-
Insulation is mounted underneath the water-proof membrane.
-
The membrane is fully subjected to The weather, which can lower its lifespan if not properly protected.
-
appropriate for buildings that prioritize insulation Charge-effectiveness around rooftop accessibility.
two. Inverted Roof System (guarded Membrane Roof or PMR)
-
The waterproof membrane lies beneath the insulation, shielding it from temperature fluctuations and UV publicity.
-
Ideal for Canada’s extreme climates and for roofs that come with pavers, terraces, or mechanical walkways.
-
makes use of dense, dampness-resistant insulation like XPS.
three. Hybrid Roof process
