Used in a partition wall and worked well. One of the best thinner solutions for insulation!

Thermal bridges not only bring loss of heat, but they also cause the warm air inside your home to cool down when it comes into contact with cold surfaces; resulting in dreaded condensation and moulding. Celotex TB4020 PIR Insulation 20mm is a BBA certified thermal insulation solution purposed to combat thermal-bridging in a variety of floor, wall and roof applications. The 2.4m x 1.2m boards are manufactured with a specially designed blowing agent that has zero ozone depletion potential (ODP) and low global warming potential (GWP); promising environmental kindness as well as maximum thermal efficiency with a thermal conductivity of just 0.022 W/m.K.
20mm Celotex PIR boards feature an aluminium foil composite front that improves thermal conductivity in sealed cavity air spaces. Celotex TB4020 is also equipped with a BRE Green Guide rating A, which can be used in your BREEAM assessments to show environmental performance.

Celotex TB4020 boards are comprised of a fibre-free rigid polyisocyanurate core and low-emissivity foil facings on either side, offering an excellent thermal conductivity of just 0.022 W/m.K. Specifically designed to eliminate thermal bridges, (as the 'TB' in its title states), TB4020 is suitable for roof, floor, and wall applications in new buildings or refurbishment projects. Thermal conductivity of 0.022w W/mK makes it the ideal solution for insulation.
This includes pitched roofs, flat roofs, solid masonry walls, timber frames, and steel framed systems. It can also be used in solid floor systems such as screed and concrete slab floors, and as loft insulation between timber rafters. Thermal conductivity of 0.022w W/mK makes it the ideal solution for insulation
Celotex TB4020 can be used in the following construction types:
Celotex TB4020 insulation board is one of the thinnest PIR insulation sizes available, and is particularly effective at overcoming thermal bridging. Celotex 20mm boards eliminate thermal bridges by providing a continuous layer of rigid polyisocyanurate PIR insulation within the building structure, providing long term energy savings.
Let's have a look at the specs:
BS EN is British and European Standard Specifications. With over 100 years of experience, the British Standards Institute is recognised as the UK’s National standards body.
Celotex is a leading British manufacturer of 20mm TB4000 PIR insulation. Founded in the early 1920s, the company has since evolved from a fibreboard insulation company to one that solely focuses on PIR insulation boards. The TB4020 insulation board is just one of many popular thermal insulation solutions in the Celotex product range. The Celotex TB4000 PIR insulation range consists of thicknesses: 20mm, 25mm, 30mm, and 40mm.
As they are super light and portable, 20mm Celotex TB4020 boards can also be handled and transported easily; making them a doddle to install. If you need to store 20mm Celotex TB4020 insulation boards for a while before installation, you should choose a cool, dry space.
Our rule of thumb when it comes to storage is that the boards should not be stored on the ground. Instead, pop them on a level surface and under a protective cover, just for good measure.
