Celotex's PIR boards achieve BBA accreditation

The UK's leading manufacturers of PIR insulation boards, Celotex has announced that three of its products have achieved Timber Frame Accreditation from the BBA.

Celotex TB4000, GA4000 and XR4000 completed the examination process.

The BBA (British Board of Agrement) accreditation means that these insulation boards are suitable for use in timber frame construction and meet the standards expected by the National House Building Council.

With the certification, Celotex now offers the most sustainable, versatile and thickest PIR insulation yet accredited for use with this method of construction.

Owing to its environmentally friendly qualities, timber frame construction is the fastest growing building method in the UK.

Currently accounting for around 24 per cent of all builds, it is expected to grow to around 30 per cent in the next two to three years - and around 50 per cent of all social housing, where environmental legislation is more stringent.

Celotex offers the first PIR rigid insulation to have achieved an A+ rating when compared to the BRE Green Guide 2008, offering a suitable match for sustainable construction such as timber frame.

The boards offer superb thermal qualities, reducing heating needs and cutting carbon emissions, and also have low Global Warming Potential and zero Ozone Depletion Potential.

Celotex also offers versatility in timber frame construction.

The three certified products are all qualified for use in inter stud, lining and sheathing applications, or any combination of the above without the addition of mineral or glass wools.

This design flexibility is also reflected in the thickness range that Celotex is certifiably suitable for.

Accredited for use on 140mm studs, the products are also accepted for use on 200mm studs.

As Celotex is the only producer to offer 200mm thick product from stock, this enables the reduction in time and cost by applying single, rather than double, layer insulation.

The rigorous accreditation saw the three Celotex products tested on key factors such as thermal efficiency, risk of condensation, fire performance and durability.

The BBA reviews the products every three years as part of its stringent examination system.
