Insulation Boards

These insulation boards form part of our wider ceiling insulation range, covering solutions for walls, floors and suspended ceilings. Secure them using suitable insulation fixings and screws selected for the insulation board, supporting substrate and installation requirements.

Insulation boards are commonly used alongside Stud and Track Systems and MF ceiling systems to improve overall building performance.

Designed for thermal efficiency, acoustic control and fire protection, rigid insulation boards are widely used across residential, commercial and industrial projects.

✔ Improve Thermal & Acoustic Performance
High-performance rigid insulation for walls, ceilings, floors and roofing applications.

Shop Insulation Boards by Type

Common Applications

Thermal Performance

Insulation boards are designed to significantly reduce heat loss, with many PIR and rigid boards achieving very low thermal conductivity values. This helps buildings meet Part L requirements and improves overall energy efficiency.

Fire Performance

Fire performance varies depending on the insulation material and complete system specification. Stone wool boards such as Rockwool offer products with Euroclass A1 non-combustible performance, while PIR boards provide high thermal performance and may form part of tested fire-resistant systems when correctly specified and installed.

Acoustic Performance

Acoustic insulation boards, particularly stone wool products, are designed to absorb sound and reduce noise transfer, making them suitable for offices, schools, partition walls and other acoustically demanding environments.

Fixing Insulation Boards

Insulation boards may require mechanical fixings to hold them securely against timber, steel, concrete, brick or blockwork substrates. The correct fixing will depend on the insulation material, board thickness, supporting substrate and required embedment.

Browse our range of insulation fixings, screws, washers and anchors to find suitable products for compatible insulation board installations. Always check the individual fixing specification and insulation manufacturer’s guidance before installation.

Frequently Asked Questions

What are insulation boards used for?

Insulation boards are used in walls, ceilings, floors and roofs to improve thermal efficiency, reduce noise transfer and provide specified levels of fire performance.

What is the difference between Rockwool and PIR boards?

Rockwool stone wool boards are commonly selected for acoustic performance and non-combustibility, while PIR boards provide high thermal resistance from a relatively slim board thickness.

Are insulation boards suitable for ceilings?

Yes, suitable insulation boards are widely used with suspended ceilings, MF ceiling systems and other compatible ceiling constructions to improve thermal or acoustic performance.

Do insulation boards reduce noise?

Yes, particularly stone wool insulation boards, which are designed to absorb sound and help reduce noise transfer through walls, floors and ceilings.

What thickness insulation board do I need?

Common thicknesses include 50mm, 75mm and 100mm, but the correct thickness depends on the required thermal or acoustic performance and the complete construction specification.

What fixings should I use for insulation boards?

The correct insulation fixing depends on the board type and thickness, supporting substrate and required embedment. Purpose-designed insulation screws, anchors, plugs or washers may be required.

Can insulation screws be used with timber and steel?

Suitable insulation screws are available for timber and steel substrates. Always check that the selected fixing is designed for the particular substrate and provides the required embedment.
