EPS provides a Price-powerful insulation solution with a great R-worth and resistance to water absorption. It’s lightweight and easy to manage but much less dense than XPS, so it’s very best Employed in techniques where weighty loading is minimum.

4. Mineral Wool (Rockwool)

Mineral wool is prized for its fire resistance and seem insulation Houses. It’s significantly fitted to buildings where hearth codes are stringent or where by sound reduction is crucial, which include industrial vegetation or hospitals.

Furthermore, it performs properly underneath large-temperature disorders and provides all-natural vapour permeability, supporting avoid trapped moisture.

five. Spray Polyurethane Foam (SPF)

SPF insulation creates a seamless, monolithic layer that adheres directly to the roof deck. It offers fantastic air sealing, humidity safety, and thermal resistance.

Reduces air leakage and warmth transfer.
functions as the two insulation and waterproofing in one software.

even so, it demands proficient applicators and stringent weather conditions through installation, which often can impact challenge scheduling.

Flat Roof Insulation Design techniques

helpful insulation isn’t pretty much substance collection — it’s regarding how Every single layer interacts in the roofing assembly. Canadian commercial roofs commonly use just one of such a few layout techniques:

1. Conventional Roof technique

Insulation is set up down below the waterproof membrane.
The membrane is absolutely exposed to the elements, which often can cut down its lifespan Otherwise properly protected.
Suitable for properties that prioritize insulation Price-effectiveness around rooftop accessibility.

2. Inverted Roof System (shielded Membrane Roof or PMR)

The water resistant membrane lies beneath the insulation, protecting it from temperature fluctuations and UV exposure.
perfect for Canada’s extreme climates and for roofs that include pavers, terraces, or mechanical walkways.
makes use of dense, moisture-resistant insulation like XPS.
