In addition it performs well below substantial-temperature ailments and delivers all-natural vapour permeability, helping avert trapped moisture.
5. Spray Polyurethane Foam (SPF)
SPF insulation generates a seamless, monolithic layer that adheres on to the roof deck. it provides excellent air sealing, humidity security, and thermal resistance.
-
cuts down air leakage and heat transfer.
-
functions as both insulation and waterproofing in one application.
However, it calls for qualified applicators and strict weather conditions all through set up, that may have an effect on task scheduling.
Flat Roof Insulation design and style techniques
powerful insulation isn’t almost product range — it’s regarding how Each individual layer interacts in the roofing assembly. Canadian business roofs generally use one of those three layout units:
1. common Roof program
-
Insulation is put in underneath the water resistant membrane.
-
The membrane is absolutely exposed to The weather, which could reduce its lifespan if not appropriately safeguarded.
-
ideal for properties that prioritize insulation Value-efficiency more than rooftop accessibility.
two. Inverted Roof procedure (safeguarded Membrane Roof or PMR)
-
The water-resistant membrane lies beneath the insulation, guarding it from temperature fluctuations and UV exposure.
-
perfect for Canada’s Severe climates and for roofs that come with pavers, terraces, or mechanical walkways.
-
makes use of dense, moisture-resistant insulation like XPS.
3. Hybrid Roof process
