Mineral wool is prized for its fire resistance and audio insulation Attributes. It’s notably suited to structures wherever hearth codes are stringent or the place sounds reduction is important, such as industrial crops or hospitals.
Furthermore, it performs nicely below substantial-temperature situations and presents natural vapour permeability, assisting reduce trapped humidity.
5. Spray Polyurethane Foam (SPF)
SPF insulation generates a seamless, monolithic layer that adheres straight to the roof deck. it provides fantastic air sealing, dampness protection, and thermal resistance.
-
lowers air leakage and warmth transfer.
-
functions as both of those insulation and waterproofing in a single software.
even so, it necessitates proficient applicators and stringent climatic conditions for the duration of set up, which often can affect venture scheduling.
Flat Roof Insulation style techniques
efficient insulation isn’t almost content variety — it’s regarding how each layer interacts throughout the roofing assembly. Canadian professional roofs typically use one particular of such three design and style programs:
one. typical Roof process
-
Insulation is installed beneath the waterproof membrane.
-
The membrane is absolutely exposed to the elements, which may reduce its lifespan Otherwise correctly safeguarded.
-
Suitable for structures that prioritize insulation cost-performance more than rooftop accessibility.
two. Inverted Roof procedure (secured Membrane Roof or PMR)
-
The water-proof membrane lies beneath the insulation, protecting it from temperature fluctuations and UV exposure.
-
Ideal for Canada’s Severe climates and for roofs that include pavers, terraces, or mechanical walkways.
-
Uses dense, humidity-resistant insulation like XPS.
