System Airtech

Specifically developed to deliver a torch-free installation where site conditions prohibit the use of open-flame. The system combines self-adhesive membranes and hot air welding.

System Airtech achieves a CCPI mark which recognises that any claims made about it have been independently assessed across 11 clauses, providing greater clarity by offering improved product information. This gives specifiers confidence in the knowledge that they will have unambiguous information when deciding which of our systems is best for their new build or refurbishment project.

When to specify

Airtech is a fully bonded system suitable for new build and refurbishment projects with a choice of insulations for warm roof construction. The system can also be used as a two-layer overlay to an existing roof that is thermally reliable and still meets current standards.

The system uses the BauderTEC KSO range of SBS modified cap sheets with three slate mineral colour finishes and installation that embraces self-adhesive membranes and hot air welding at all detailing and laps.

Plus points

■□ Entire system features flame-free installation.
■□ Tested bond strength for adhesives.
■□ Comprehensive range of guarantee packages to fulfil cover requirements for the project (dependant on system/product selection). For more information contact our technical dept for a sample guarantee outlining cover level, terms and conditions.

Bauder Torch-Free Detailing Methods 

Safe2Torch industry initiativeOur torch-free detail design specifically delivers secure safe application techniques in the vicinity of combustible construction materials located on, or connected to, the roof such as timber substrates or upstands; abutments to cladding, roof tiles, slates or thatch; or even debris such as dry leaf material that is at risk from ignition.  The application methods meet NFRC Guidance Document 'Safe2Torch'.
