EPS provides a cost-productive insulation Alternative with a great R-value and resistance to water absorption. It’s lightweight and straightforward to manage but a lot less dense than XPS, so it’s very best Utilized in techniques where by large loading is minimum.
4. Mineral Wool (Rockwool)
Mineral wool is prized for its fireplace resistance and audio insulation Homes. It’s especially suited to buildings where hearth codes are stringent or where by sounds reduction is very important, for example industrial plants or hospitals.
What's more, it performs nicely beneath substantial-temperature problems and provides pure vapour permeability, serving to stop trapped moisture.
five. Spray Polyurethane Foam (SPF)
SPF insulation creates a seamless, monolithic layer that adheres directly to the roof deck. It offers superb air sealing, humidity defense, and thermal resistance.
-
Reduces air leakage and heat transfer.
-
functions as equally insulation and waterproofing in one application.
on the other hand, it calls for experienced applicators and stringent weather conditions during installation, which may impact job scheduling.
Flat Roof Insulation structure methods
Effective insulation isn’t nearly materials choice — it’s about how Every layer interacts inside the roofing assembly. Canadian industrial roofs normally use a single of these a few style and design units:
one. standard Roof System
-
Insulation is installed under the water-resistant membrane.
-
The membrane is fully exposed to The weather, which can lessen its lifespan if not thoroughly shielded.
-
Suitable for buildings that prioritize insulation Value-efficiency more than rooftop accessibility.
two. Inverted Roof process (Protected Membrane Roof or PMR)
-
The water-resistant membrane lies beneath the insulation, shielding it from temperature fluctuations and UV publicity.
-
perfect for Canada’s Serious climates and for roofs that include pavers, terraces, or mechanical walkways.
-
Uses dense, moisture-resistant insulation like XPS.
3. Hybrid Roof System
-
Combines features of both equally conventional and inverted units.
