Wall Insulation Board TP10/TF70/TW55
Wall insulation boards are essential building materials that help keep interiors warm and energy-efficient. Most of these boards create a thermal and acoustic barrier that enhances comfort and efficiency year-round.
They are suitable for both external and internal walls, making them ideal for new builds, retrofits, and energy upgrades.
What is the wall insulation board?
A wall insulation board is a rigid or semi-rigid panel that forms a continuous thermal and acoustic barrier to reduce heat transfer and sound transmission through walls.
Commonly made from PIR, EPS, or mineral wool, wall insulation boards balance efficiency, safety, and practicality in one simple installation.
For interior upgrades, acoustic insulated plasterboard or sound proofing plasterboard provides insulation and a ready-to-finish surface. For external walls, rigid insulation boards act as the main layer in external wall insulation systems, improving the building’s envelope and weather protection.
What is wall insulation board used for?
Wall insulation boards can be fitted across various building applications to control temperature, noise, and condensation. Common uses include:
- Internal walls: Plaster insulation boards or acoustic insulated plasterboard for warmth and soundproofing.
- External walls: Fitted as external wall insulation boards under render or cladding systems for improved weather resistance and energy efficiency.
- Cavity walls: Installed as cavity wall insulation boards to prevent air leakage and thermal bridging.
- Partitions and separating walls: Used as sound insulation wall panels for improved acoustic performance.
- Loft conversions and refurbishments: To help meet Part L energy requirements in older homes.
Types of wall insulation board
We supply a complete selection of wall insulation boards tailored for every build type and performance need:
- PIR Wall Insulation Boards: High-performance boards with low thermal conductivity and strong compressive strength.
- EPS Wall Insulation Boards: Lightweight, cost-effective insulation for cavity and external wall systems.
- Mineral Wool Wall Boards: Fire-resistant and sound-absorbing. Ideal for acoustic and safety-focused applications.
- Plaster Insulation Boards: Combined rigid insulation and plasterboard for fast, dual-purpose wall lining.
- Acoustic Insulated Plasterboard: Ideal for soundproofing internal partitions and media rooms.
- External Wall Insulation Boards: Designed for use under render or rainscreen façades for enhanced energy performance.
Benefits of wall insulation board
A wall insulation board does more than keep your home warm. It transforms your space into an energy-efficient, quiet, and resilient structure. Here is what else it offers:
- Improved thermal comfort: Keeps interiors warmer in winter and cooler in summer.
- Enhanced energy efficiency: Reduces heat loss through walls, helping achieve compliance with current UK U-value requirements.
- Sound control: Sound insulation wall panels and acoustic plasterboards block unwanted noise for quieter living.
- Moisture resistance: External and cavity boards resist damp and help prevent condensation buildup. Best results when paired with vapour control layers in moisture-prone areas.
- Easy installation: Suitable for dot-and-dab fixing, mechanical fastening, or adhesive systems.
- Potential energy savings: Cuts energy costs by reducing reliance on heating and air conditioning systems.

FAQ
How to install wall insulation board?
- Step: Clean and prepare the wall surface.
- Step: Fix the boards, ensuring no gaps between them.
- Step: Apply adhesive dots or use mechanical fixings to secure each board.
- Step: Seal all joints with insulation tape.
- Step: Skim or finish with plasterboard as required.
- Step: Add a vapour control layer to minimise condensation (optional).
How do you attach insulation board to a wall?
You can attach insulation boards using strong construction adhesive, insulation fixings, or a combination of both. The direct dot-and-dab method is used primarily for plasterboard-backed options.
How to add insulation to interior walls?
The easiest way is to use internal wall insulating panels or acoustic insulated plasterboard. These are two-in-one products that combine insulation with a ready-to-finish surface. Simply fix them to internal walls, seal the joints, and skim for a seamless finish.
What is the cheapest way to insulate internal walls from inside?
Expanded Polystyrene (EPS) wall insulation boards are the most budget-friendly option. They’re light, easy to cut, and deliver solid performance at an affordable price, making them ideal for DIY or large-scale refits.
