SPF insulation generates a seamless, monolithic layer that adheres directly to the roof deck. It offers outstanding air sealing, dampness defense, and thermal resistance.
-
minimizes air leakage and warmth transfer.
-
functions as equally insulation and waterproofing in one application.
However, it needs competent applicators and strict weather conditions through installation, which can affect venture scheduling.
Flat Roof Insulation layout methods
powerful insulation isn’t pretty much content choice — it’s about how Just about every layer interacts throughout the roofing assembly. Canadian industrial roofs typically use just one of these three structure units:
one. standard Roof process
-
Insulation is installed below the water-resistant membrane.
-
The membrane is totally exposed to The weather, that may minimize its lifespan Otherwise properly guarded.
-
Suitable for structures that prioritize insulation Expense-performance about rooftop accessibility.
2. Inverted Roof method (Protected Membrane Roof or PMR)
-
The watertight membrane lies beneath the insulation, defending it from temperature fluctuations and UV exposure.
-
perfect for Canada’s Severe climates and for roofs that come with pavers, terraces, or mechanical walkways.
-
Uses dense, moisture-resistant insulation like XPS.
3. Hybrid Roof process
-
