4. Mineral Wool (Rockwool)
Mineral wool is prized for its fire resistance and sound insulation Homes. It’s specifically fitted to structures the place hearth codes are stringent or exactly where sounds reduction is significant, for example industrial crops or hospitals.
Furthermore, it performs very well beneath higher-temperature problems and delivers normal vapour permeability, supporting stop trapped humidity.
five. Spray Polyurethane Foam (SPF)
SPF insulation produces a seamless, monolithic layer that adheres directly to the roof deck. It offers superb air sealing, humidity protection, and thermal resistance.
-
decreases air leakage and warmth transfer.
-
functions as both equally insulation and waterproofing in a single application.
nevertheless, it demands experienced applicators and rigid weather conditions all through set up, which can impact undertaking scheduling.
Flat Roof Insulation style and design ways
helpful insulation isn’t pretty much materials collection — it’s about how each layer interacts throughout the roofing assembly. Canadian business roofs commonly use 1 of those three design and style techniques:
1. typical Roof technique
-
Insulation is mounted beneath the water-proof membrane.
-
The membrane is thoroughly subjected to the elements, which can cut down its lifespan Otherwise correctly shielded.
-
appropriate for buildings that prioritize insulation Price tag-performance over rooftop accessibility.
2. Inverted Roof method (shielded Membrane Roof or PMR)
-
The watertight membrane lies beneath the insulation, safeguarding it from temperature fluctuations and UV exposure.
-
perfect for Canada’s extreme climates and for roofs that come with pavers, terraces, or mechanical walkways.
-
makes use of dense, humidity-resistant insulation like XPS.
3. Hybrid Roof technique
