TB4030 Celotex 30mm PIR Insulation Board Applications

With low emissivity foil facings, TB4030 is manufactured from rigid polyisocyanurate (PIR) using a blend of blowing agents that have zero ozone depletion potential (zero ODP) and low global warming potential (GWP). Specifically designed to eliminate thermal bridges, (as the 'TB' in its title states), TB4030 is suitable for roof, floor, and wall applications in new buildings or refurbishment projects, giving improved thermal insulation performance within cavity air spaces. Its thermal conductivity of 0.022w W/mK makes it the ideal solution for insulation in 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. 

Celotex TB4030 can be used in the following construction types:

• Ground Floor - Concrete Slab (perimeter upstand)
• Ground Floor - Beam and Block (perimeter upstand)
• Ground Floor - Suspended Timber Joists (perimeter upstand)
• Ground Floor - Upgrading Existing Concrete Slab (perimeter upstand)
• External Wall - Timber Frame Internal Linings
• External Wall - Masonry Cavity Internal Linings
• External Wall - Solid Masonry Internal Linings
• Pitched Roof - Below Timber Rafters
• Pitched Roof - Above Timber Rafters

Celotex TB4030 Specifications

Celotex TB4030 multi-purpose insulation board is your one-stop solution when it comes to overcoming thermal bridging. Celotex 30mm TB4030 boards were developed as a simple solution to overcome localised thermal bridges by providing a continuous layer of rigid polyisocyanurate PIR insulation within the building structure. 

Let's have a look at the specs:

• Excellent thermal conductivity of 0.022w W/mK
• Low emissivity foil facing provides improved thermal performance in sealed cavity air spaces
• Complies with UK Building Regulations with better U-values and thinner solutions
• Zero Global Warming Potential (GWP) and Zero Ozone Depleting Potential (ODP)
• Easy to install
• BBA certified - Celotex TB4030 has been assessed by the BBA as fit for use in defined roof, wall and floor applications if installed, used and maintained as set out in the certificate
• Achieves a BRE Green Guide Rating of A, which can assist in demonstrating environmental performance in your BREEAM assessments
• Lightweight 2400 x 1200mm boards

About Celotex

Celotex is a leading British manufacturer of 30mm 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 TB4030 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.

30mm Celotex TB4030 Insulation Storage & Handling

As they are super light and portable, 30mm Celotex TB4030 boards can also be handled and transported easily; making them a doddle to install. If you need to store 30mm Celotex TB4030 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.
