EPS offers a cost-powerful insulation Option with a very good R-value and resistance to water absorption. It’s lightweight and straightforward to handle but less dense than XPS, so it’s ideal Utilized in techniques in which weighty loading is negligible.

4. Mineral Wool (Rockwool)

Mineral wool is prized for its fire resistance and audio insulation Houses. It’s significantly fitted to structures where fire codes are stringent or in which sounds reduction is important, including industrial plants or hospitals.

Furthermore, it performs very well beneath substantial-temperature problems and offers normal vapour permeability, assisting stop trapped humidity.

5. Spray Polyurethane Foam (SPF)

SPF insulation generates a seamless, monolithic layer that adheres straight to the roof deck. it provides exceptional air sealing, moisture safety, and thermal resistance.

decreases air leakage and heat transfer.
Acts as both insulation and waterproofing in one software.

having said that, it necessitates qualified applicators and stringent climatic conditions through installation, which could have an impact on project scheduling.

Flat Roof Insulation design and style strategies

efficient insulation isn’t pretty much product range — it’s regarding how Each and every layer interacts within the roofing assembly. Canadian business roofs commonly use just one of those a few structure techniques:

one. Conventional Roof technique

Insulation is mounted under the water-proof membrane.
The membrane is entirely subjected to The weather, which may cut down its lifespan Otherwise adequately secured.
suited to structures that prioritize insulation cost-efficiency in excess of rooftop accessibility.

2. Inverted Roof technique (guarded Membrane Roof or PMR)

The water resistant membrane lies beneath the insulation, defending it from temperature fluctuations and UV exposure.
perfect for Canada’s Intense climates and for roofs that come with pavers, terraces, or mechanical walkways.
utilizes dense, dampness-resistant insulation like XPS.

three. Hybrid Roof process

Combines functions of equally typical and inverted programs.
delivers double-layer insulation for superior thermal resistance.
frequently used in significant-effectiveness or Electrical power-economical industrial properties.

Every structure calls for exact slope intending to make certain successful drainage and forestall ponding — An important factor in roof deterioration in cold and soaked locations.

important Installation concerns

Insulation general performance is dependent as much on right set up as on content high-quality. in this article’s what contractors and developing homeowners need to deal with during commercial flat roof jobs:

Vapour Barrier Placement – In colder climates, vapour barriers need to be placed on the warm aspect with the insulation to halt indoor dampness from achieving cold layers.
various levels with Staggered Joints – utilizing two or more layers of insulation with staggered seams lowers thermal bridging and air leaks.
Adhesion and Fastening – Boards could be mechanically fastened, adhered with hot asphalt or cold adhesives, or ballasted depending upon the system.
Tapered Insulation – to market h2o runoff, tapered boards are made use of to produce a Light slope towards drains.
