SPF insulation makes a seamless, monolithic layer that adheres directly to the roof deck. it provides exceptional air sealing, dampness protection, and thermal resistance.
-
minimizes air leakage and heat transfer.
-
functions as both of those insulation and waterproofing in a single software.
even so, it necessitates competent applicators and rigorous weather conditions all through installation, which can impact undertaking scheduling.
Flat Roof Insulation structure ways
successful insulation isn’t just about materials variety — it’s about how Each individual layer interacts in the roofing assembly. Canadian business roofs typically use just one of such 3 style and design methods:
1. common Roof procedure
-
Insulation is put in down below the water resistant membrane.
-
The membrane is totally exposed to The weather, which often can decrease its lifespan if not correctly protected.
-
ideal for properties that prioritize insulation Expense-performance in excess of rooftop accessibility.
2. Inverted Roof program (Protected Membrane Roof or PMR)
-
The water-resistant membrane lies beneath the insulation, protecting it from temperature fluctuations and UV publicity.
