Celotex CW4000 Cavity Wall Insulation Board is a polyisocyanurate (PIR) insulation solution manufactured for use in partial fill cavity walls. Comprised of a PIR core sandwiched between low emissivity foil facings on both sides, these boards have a thermal conductivity of just 0.022 W/mK. This makes them a far more effective thermal cavity solution than either rock or glass wool insulation. These cavity insulation batts fit snugly in between cavity wall ties, and are perfect for use in new builds and extensions with a masonry wall. Celotex CW4000 is a BBA certified solution and is the leading brand in the market for PIR cavity wall insulation. Sized at 1200mm x 450mm, these boards are rigid, lightweight and easy to handle and install. They are sold in wrapped plastic packs.

75mm Celotex Cavity Wall Insulation Board Product Description


For improved thermal insulation performance, look no further than Celotex CW4075. This is a partial-fill 75mm cavity wall insulation board aimed specifically at combining affordability with excellent thermal protection. It is made from PIR, which has a thermal conductivity value of 0.022 W/mK. This high performance insulation board comprises a polyisocyanurate core flanked by low emissivity foil facings on either side. The conveniently sized boards can be fitted in new build or refurbishment insulation projects.

Homeowners lose over a third of the heat in their homes through the walls. By investing in partial-fill 75mm Celotex cavity wall insulation, you can reduce your energy bills and keep your home warmer for longer.

Celotex CW4000 is British Board Approved (BBA) for use as partial fill insulation in cavity walls and complies with building regulations for improving the thermal envelope of your home. It is manufactured with a blowing agent that has zero ODP and low Global Warming Potential Potential (GWP), which makes it environmentally sound.

75mm Cavity Wall Insulation Applications

Celotex 75mm wall insulation is designed for installation in external masonry cavity walls for enhanced thermal performance. A cavity describes two external walls that are separated by an air gap. These walls are often referred to as masonry leaves.

PIR is a good choice for homeowners who want to protect their homes from the elements and prevent air movement and heat loss in vulnerable exposure zones. It is a closed-cell, water repellent insulation board. PIR insulation promises durability and excellent thermal protection, better than that of most other building materials.

These partial fill cavity batts are sized at 1200mm x 450mm to suit standard wall tie spacings and provide a closed joint with adjacent boards.

75mm Cavity Insulation PIR Core

Celotex CW4075 is comprised of a PIR core and foil facings on either side. PIR is one of the most popular insulation materials on the market because it delivers excellent thermal protection at an affordable price.

PIR has a thermal conductivity of 0.022 W/mK, making it one of the most thermally efficient insulation materials available today. Celotex CW4075 is also extremely lightweight and easy to handle. It has a fire rating of E on the Euroclass Scale, which means that it has a high contribution to fire.

75mm Wall Insulation Installation

75mm cavity wall insulation is easy to install. It is manufactured for use in cavity walls and its size of 1200mm x 450mm is specifically designed to suit standard wall tie spacings. Most people use the wall ties that hold the two skins of the masonry walls together to secure their partial-fill insulation. You should install the wall ties in the inner leaf at 450mm height.

  • Rigid partial fill cavity wall insulation
  • Aluminium composite facing on both sides
  • 0.022 W/mK thermal conductivity
  • Easy to handle and install
