- Polystyrene (EPS and XPS): Lightweight synthetic materials with high thermal resistance. EPS is used for walls and below-ground applications, while XPS is more durable and suitable for roofing and foundation insulation.
- Polyurethane (PUR and PIR): Foam-based insulation with exceptional thermal resistance. PUR is more rigid and dense, while PIR is less flammable and has a higher R-value.
Insulation Types
Insulation is available in various forms, each with its own advantages:
- Batts and Rolls: Flexible and easily installed, ideal for walls and attics.
- Loose-Fill: Poured into cavities or blown into place, providing excellent coverage and filling irregular spaces.
- Rigid Boards: Sturdy and self-supporting, used for roofing, walls, and under-slab applications.
- Spray Foam: Applied as a liquid that expands and hardens, creating an air-tight seal and providing excellent insulation and soundproofing.
Installation and Roof Systems
When it comes to roof insulation, the method of installation and the type of roof system play crucial roles in ensuring optimal performance.
Installation Methods:
- Mechanically Fastened: Insulation boards or rolls are attached to the roof deck using fasteners such as screws or nails. Ideal for flat roofs with significant foot traffic or load-bearing requirements.
- Adhesive: Insulation is glued to the roof deck using specialized adhesives. Suitable for low-slope roofs or where fasteners may puncture the membrane.
- Loose-fill or Spray Foam: Loose-fill insulation (e.g., cellulose, fiberglass) or spray foam is applied in a continuous layer over the roof deck. Provides good coverage and conforms to irregular surfaces.
Flat Roof Types:
- Built-Up Roof (BUR): Multiple layers of asphalt felt and bitumen are applied to create a waterproof membrane. Provides longevity and durability.
- Modified Bitumen Roof (MBR): Similar to BUR, but with a polymer-modified asphalt layer. Offers enhanced flexibility and weather resistance.
- Single-Ply Membrane Roof (PVC, TPO): A single layer of synthetic sheeting (PVC or TPO) is installed over the roof deck. Lightweight and highly reflective, reducing energy costs.
- Metal Roof: Metal panels are installed over the roof deck. Fire-resistant and durable, but may require additional insulation to maintain thermal comfort.
- Green Roof: A vegetated layer is installed over the insulation, providing stormwater management, insulation, and aesthetic benefits.
The choice of installation method and roof system depends on factors such as roof slope, load requirements, budget, and desired performance. Consulting with a qualified roofing contractor is highly recommended to determine the most appropriate approach for your specific needs.
