EPS provides a Expense-effective insulation Answer with a very good R-value and resistance to drinking water absorption. It’s lightweight and simple to handle but considerably less dense than XPS, so it’s very best Utilized in techniques where major loading is small.

four. Mineral Wool (Rockwool)

Mineral wool is prized for its fire resistance and audio insulation Houses. It’s notably suited to buildings in which fireplace codes are stringent or exactly where sounds reduction is very important, such as industrial crops or hospitals.

Furthermore, it performs effectively beneath significant-temperature circumstances and offers organic vapour permeability, helping prevent trapped moisture.

5. Spray Polyurethane Foam (SPF)

SPF insulation results in a seamless, monolithic layer that adheres directly to the roof deck. it provides great air sealing, humidity protection, and thermal resistance.

decreases air leakage and heat transfer.
functions as equally insulation and waterproofing in a single software.

nonetheless, it requires expert applicators and stringent weather conditions all through installation, that may impact venture scheduling.

Flat Roof Insulation design and style methods

successful insulation isn’t pretty much materials range — it’s about how Each individual layer interacts throughout the roofing assembly. Canadian commercial roofs usually use a person of these 3 design and style units:

one. common Roof procedure

Insulation is put in under the watertight membrane.
The membrane is fully exposed to the elements, that may decrease its lifespan if not correctly shielded.
well suited for buildings that prioritize insulation Price-effectiveness more than rooftop accessibility.

two. Inverted Roof method (secured Membrane Roof or PMR)

The waterproof membrane lies beneath the insulation, safeguarding it from temperature fluctuations and UV exposure.
perfect for Canada’s Extraordinary climates and for roofs which include pavers, terraces, or mechanical walkways.
utilizes dense, moisture-resistant insulation like XPS.

three. Hybrid Roof procedure
