four. Mineral Wool (Rockwool)
Mineral wool is prized for its hearth resistance and sound insulation Houses. It’s specifically suited to buildings where hearth codes are stringent or where sound reduction is significant, which include industrial plants or hospitals.
In addition it performs effectively under large-temperature problems and provides all-natural vapour permeability, helping avoid trapped humidity.
five. Spray Polyurethane Foam (SPF)
SPF insulation generates a seamless, monolithic layer that adheres on to the roof deck. It offers excellent air sealing, moisture defense, and thermal resistance.
-
lowers air leakage and heat transfer.
-
functions as equally insulation and waterproofing in a single application.
nonetheless, it requires skilled applicators and strict climatic conditions for the duration of installation, which often can have an effect on project scheduling.
Flat Roof Insulation design and style methods
helpful insulation isn’t almost substance choice — it’s regarding how Every single layer interacts inside the roofing assembly. Canadian business roofs commonly use a person of these three layout programs:
one. typical Roof System
-
Insulation is mounted underneath the water-resistant membrane.
-
The membrane is thoroughly exposed to The weather, which can minimize its lifespan if not properly shielded.
-
suited to properties that prioritize insulation Value-performance about rooftop accessibility.
two. Inverted Roof method (guarded Membrane Roof or PMR)
-
The waterproof membrane lies beneath the insulation, guarding it from temperature fluctuations and UV publicity.
-
Ideal for Canada’s Severe climates and for roofs which include pavers, terraces, or mechanical walkways.
-
makes use of dense, dampness-resistant insulation like XPS.
3. Hybrid Roof technique
