EPS provides a Price-helpful insulation Alternative with a fantastic R-worth and resistance to h2o absorption. It’s lightweight and straightforward to deal with but considerably less dense than XPS, so it’s very best Utilized in techniques wherever hefty loading is nominal.
4. Mineral Wool (Rockwool)
Mineral wool is prized for its fire resistance and audio insulation Qualities. It’s especially suited for structures wherever fire codes are stringent or in which sounds reduction is important, for instance industrial crops or hospitals.
In addition it performs very well underneath substantial-temperature problems and delivers organic vapour permeability, helping avert trapped dampness.
5. Spray Polyurethane Foam (SPF)
SPF insulation produces a seamless, monolithic layer that adheres on to the roof deck. It offers excellent air sealing, dampness safety, and thermal resistance.
-
decreases air leakage and heat transfer.
-
functions as each insulation and waterproofing in a single software.
on the other hand, it necessitates competent applicators and strict weather conditions for the duration of installation, that may have an affect on project scheduling.
Flat Roof Insulation style methods
helpful insulation isn’t pretty much product variety — it’s regarding how Every layer interacts within the roofing assembly. Canadian industrial roofs typically use 1 of such 3 structure devices:
one. common Roof technique
-
Insulation is set up down below the watertight membrane.
-
The membrane is completely subjected to The weather, which could cut down its lifespan Otherwise adequately protected.
-
well suited for structures that prioritize insulation Price-effectiveness above rooftop accessibility.
2. Inverted Roof System (secured Membrane Roof or PMR)
-
The water-proof membrane lies beneath the insulation, protecting it from temperature fluctuations and UV exposure.
-
perfect for Canada’s Extraordinary climates and for roofs that include pavers, terraces, or mechanical walkways.
-
utilizes dense, humidity-resistant insulation like XPS.
three. Hybrid Roof System
-
