4. Mineral Wool (Rockwool)
Mineral wool is prized for its fire resistance and audio insulation Homes. It’s specifically suited for structures where by hearth codes are stringent or in which noise reduction is essential, which include industrial vegetation or hospitals.
Furthermore, it performs well underneath significant-temperature circumstances and delivers purely natural vapour permeability, supporting protect against trapped dampness.
five. Spray Polyurethane Foam (SPF)
SPF insulation creates a seamless, monolithic layer that adheres straight to the roof deck. It offers excellent air sealing, moisture security, and thermal resistance.
-
lessens air leakage and heat transfer.
-
functions as both insulation and waterproofing in a single application.
even so, it requires expert applicators and rigorous weather conditions throughout installation, that may have an affect on job scheduling.
Flat Roof Insulation structure strategies
efficient insulation isn’t just about material assortment — it’s regarding how Just about every layer interacts within the roofing assembly. Canadian business roofs generally use one of such a few layout programs:
one. typical Roof System
-
Insulation is put in down below the water-proof membrane.
-
The membrane is absolutely exposed to the elements, that may decrease its lifespan if not properly guarded.
-
well suited for properties that prioritize insulation Charge-efficiency about rooftop accessibility.
two. Inverted Roof System (secured Membrane Roof or PMR)
-
The waterproof membrane lies beneath the insulation, preserving it from temperature fluctuations and UV exposure.
-
Ideal for Canada’s Severe climates and for roofs which include pavers, terraces, or mechanical walkways.
