Acts as both equally insulation and waterproofing in one application.
having said that, it involves expert applicators and rigid weather conditions in the course of installation, which could have an impact on undertaking scheduling.
Flat Roof Insulation structure ways
helpful insulation isn’t pretty much material choice — it’s about how Each and every layer interacts within the roofing assembly. Canadian business roofs typically use just one of these three structure devices:
one. traditional Roof procedure
-
Insulation is put in beneath the water-proof membrane.
-
The membrane is fully subjected to the elements, which often can minimize its lifespan Otherwise properly safeguarded.
-
well suited for buildings that prioritize insulation cost-effectiveness over rooftop accessibility.
two. Inverted Roof procedure (secured Membrane Roof or PMR)
-
The water-proof membrane lies beneath the insulation, protecting it from temperature fluctuations and UV publicity.
-
perfect for Canada’s extreme climates and for roofs that come with pavers, terraces, or mechanical walkways.
