In addition, it performs nicely beneath substantial-temperature circumstances and supplies pure vapour permeability, encouraging reduce trapped moisture.
5. Spray Polyurethane Foam (SPF)
SPF insulation makes a seamless, monolithic layer that adheres directly to the roof deck. It offers excellent air sealing, moisture safety, and thermal resistance.
-
lowers air leakage and heat transfer.
-
Acts as both of those insulation and waterproofing in one software.
having said that, it necessitates expert applicators and stringent climatic conditions throughout set up, that may have an impact on project scheduling.
Flat Roof Insulation style and design Approaches
powerful insulation isn’t nearly materials collection — it’s regarding how Each and every layer interacts inside the roofing assembly. Canadian business roofs usually use one particular of those 3 design and style systems:
one. regular Roof technique
-
Insulation is mounted under the water-resistant membrane.
-
The membrane is absolutely subjected to the elements, that may reduce its lifespan if not appropriately shielded.
-
suited to properties that prioritize insulation Price tag-effectiveness more than rooftop accessibility.
two. Inverted Roof procedure (shielded Membrane Roof or PMR)
-
The water resistant membrane lies beneath the insulation, protecting it from temperature fluctuations and UV publicity.
-
perfect for Canada’s Extraordinary climates and for roofs which include pavers, terraces, or mechanical walkways.
