four. Mineral Wool (Rockwool)

Mineral wool is prized for its fire resistance and audio insulation Attributes. It’s significantly suited for buildings exactly where fireplace codes are stringent or where by sound reduction is very important, including industrial crops or hospitals.

Furthermore, it performs very well less than high-temperature situations and offers pure vapour permeability, aiding avert trapped humidity.

5. Spray Polyurethane Foam (SPF)

SPF insulation generates a seamless, monolithic layer that adheres straight to the roof deck. it provides exceptional air sealing, moisture defense, and thermal resistance.

minimizes air leakage and warmth transfer.
Acts as the two insulation and waterproofing in one application.

nonetheless, it necessitates proficient applicators and rigorous weather conditions in the course of set up, which may have an impact on job scheduling.

Flat Roof Insulation style and design techniques

productive insulation isn’t almost content collection — it’s regarding how each layer interacts in the roofing assembly. Canadian professional roofs commonly use one particular of such 3 design and style techniques:

1. common Roof process

Insulation is mounted underneath the watertight membrane.
The membrane is entirely exposed to The weather, which could minimize its lifespan Otherwise adequately shielded.
ideal for buildings that prioritize insulation Price-efficiency above rooftop accessibility.

two. Inverted Roof procedure (guarded Membrane Roof or PMR)

The water-resistant membrane lies beneath the insulation, guarding it from temperature fluctuations and UV publicity.
Ideal for Canada’s Excessive climates and for roofs which include pavers, terraces, or mechanical walkways.
employs dense, humidity-resistant insulation like XPS.

three. Hybrid Roof method
