Mineral wool is prized for its hearth resistance and audio insulation properties. It’s notably fitted to buildings exactly where fireplace codes are stringent or where sounds reduction is vital, which include industrial crops or hospitals.
In addition, it performs properly underneath substantial-temperature problems and presents purely natural vapour permeability, aiding reduce trapped humidity.
five. Spray Polyurethane Foam (SPF)
SPF insulation creates a seamless, monolithic layer that adheres straight to the roof deck. it provides outstanding air sealing, humidity protection, and thermal resistance.
-
lowers air leakage and heat transfer.
-
functions as both of those insulation and waterproofing in a single application.
However, it involves qualified applicators and rigorous climatic conditions throughout set up, that may affect job scheduling.
Flat Roof Insulation design and style methods
helpful insulation isn’t nearly substance variety — it’s regarding how Every single layer interacts in the roofing assembly. Canadian professional roofs generally use just one of those three design programs:
1. regular Roof program
-
Insulation is put in beneath the waterproof membrane.
-
The membrane is absolutely subjected to the elements, which could cut down its lifespan Otherwise appropriately safeguarded.
-
Suitable for buildings that prioritize insulation Expense-effectiveness in excess of rooftop accessibility.
two. Inverted Roof method (guarded Membrane Roof or PMR)
-
The water resistant membrane lies beneath the insulation, guarding it from temperature fluctuations and UV exposure.
-
Ideal for Canada’s extreme climates and for roofs that come with pavers, terraces, or mechanical walkways.
-
works by using dense, moisture-resistant insulation like XPS.
3. Hybrid Roof process
