-
cuts down air leakage and heat transfer.
-
functions as both of those insulation and waterproofing in a single software.
even so, it necessitates competent applicators and demanding weather conditions all through set up, which may have an effect on project scheduling.
Flat Roof Insulation layout strategies
helpful insulation isn’t pretty much material range — it’s regarding how Just about every layer interacts within the roofing assembly. Canadian professional roofs usually use 1 of those 3 style and design systems:
one. Conventional Roof technique
-
Insulation is installed below the water-proof membrane.
-
The membrane is fully subjected to The weather, which might reduce its lifespan Otherwise effectively shielded.
-
appropriate for structures that prioritize insulation Price tag-effectiveness around rooftop accessibility.
two. Inverted Roof process (Protected Membrane Roof or PMR)
-
The water-proof membrane lies beneath the insulation, preserving it from temperature fluctuations and UV exposure.
-
Ideal for Canada’s extreme climates and for roofs which include pavers, terraces, or mechanical walkways.
-
makes use of dense, dampness-resistant insulation like XPS.
3. Hybrid Roof process
