In addition, it performs very well less than large-temperature situations and presents normal vapour permeability, encouraging stop trapped dampness.
5. Spray Polyurethane Foam (SPF)
SPF insulation results in a seamless, monolithic layer that adheres directly to the roof deck. It offers exceptional air sealing, moisture defense, and thermal resistance.
-
lessens air leakage and warmth transfer.
-
functions as both equally insulation and waterproofing in one software.
on the other hand, it requires skilled applicators and demanding climatic conditions for the duration of installation, which could have an impact on challenge scheduling.
Flat Roof Insulation Design techniques
productive insulation isn’t just about content selection — it’s about how Every single layer interacts within the roofing assembly. Canadian industrial roofs normally use a single of those three style and design techniques:
1. traditional Roof procedure
-
Insulation is set up below the water resistant membrane.
-
The membrane is totally subjected to The weather, which often can reduce its lifespan if not appropriately secured.
-
Suitable for structures that prioritize insulation Price tag-efficiency more than rooftop accessibility.
2. Inverted Roof program (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 Serious climates and for roofs that include pavers, terraces, or mechanical walkways.
-
Uses dense, moisture-resistant insulation like XPS.
three. Hybrid Roof System
-
Combines functions of both regular and inverted programs.
