Insulation and cover boards play a crucial role in flat and low-slope roofing build-ups. They are one of the main ways to reduce heat loss from properties, contributing to the roof's thermal performance and increasing the building’s energy efficiency.
Adhesives are widely used to bond insulation and cover board layers because they provide a strong, uniform bond. Adhesive bonding is particularly beneficial in achieving a seamless, efficient, and durable roofing system, eliminating the thermal bridging caused by the mechanical attachments.
Our insulation adhesive range has been developed specifically for securely bonding a wide range of insulation and cover boards types to various roof decks/substrates. Whether you're working with polyisocyanurate (PIR), EPS, XPS, mineral wool, or Foamglas insulation, or gypsum or cement cover boards, our adhesives create strong, reliable, and efficient bonds. Numerous application systems are available to suit need and budget, including traditional pail-applied, cartridge-applied, spray-applied, and pump-grade products.
Polyisocyanurate insulation boards are rigid foam insulation panels with excellent thermal performance. They are either faced with glass tissue or foil for additional protection.
We have a range of single-component and two-component bonding adhesives, all suitable for adhering polyisocyanurate boards, including glass tissue-faced and foil-faced (to a porous surface), and are available in multiple application systems. Our two-component adhesives are recommended for foil-to-foil bonding, as they do not rely on moisture to activate the curing process.
EPS is a rigid insulation made from expanded polystyrene beads. It is a lightweight, easy-to-handle, and cost-effective insulation option.
Our moisture-curing polyurethane adhesives and two-component adhesives are most suitable for EPS insulation, and are available as pail-applied, cartridge-applied, and spray-applied, including pressurized canister, products. The lightweight adhesive solutions prevent damage to fragile EPS boards.
XPS is a rigid, closed-cell foam insulation made from extruded polystyrene. It is known for its excellent water resistance and high compressive strength, ideal for load-bearing applications.
Our moisture-curing polyurethane adhesives and two-component adhesives are most suitable for EPS insulation, and are available as pail-applied, cartridge-applied, and spray-applied, including pressurized canister, products.
Mineral wool, also known as stone wool or rock wool, is made from molten rock fibers, offering excellent fire resistance and acoustic insulation.
Our two-component adhesives are most suited for bonding porous materials such as mineral wool insulation, due to the high foaming structure of the adhesives. Our adhesives provide high-strength adhesion without compressing the material, and maintain its fire-resistant and acoustic properties.
Foamglas is a high-performance cellular glass insulation. Made from 100% glass, it has a closed-cell structure that provides exceptional thermal insulation, moisture resistance, and fire protection.
Our two-component cartridge-applied polyurethane adhesives are most suited for bonding porous materials including Foamglas insulation, due to the high foaming structure of the adhesives.
Cover boards are rigid, durable boards installed between the insulation and the waterproofing membrane in roofing systems. They can offer improved protection, moisture resistance, and thermal efficiency. Common materials include gypsum, high-density polyisocyanurate, and cementitious boards.
Our moisture-curing polyurethane and two-component adhesives are all suitable for bonding cover boards, and are available in multiple application systems.
