Bituminous Roof Systems - Airtech System

When to specify...

When a high quality bitumen system is required, but  site conditions prohibit the use of hot works, Airtech is an extremely effective torch-free bitumen membrane solution using hot air welding at the laps. It can be specified in both warm and cold roof design on all normal types of deck construction and is equally suited to either new build or refurbishment projects.

 

1 Bauder KSO SN or Bauder KSO-P SN cap sheet	KSO SN. Self-adhesive elastomeric bitumen capping sheet.
2  BauderTEC KSA DUO underlayer	Self-adhesive elastomeric bitumen underlayer
3  PIR FA-TE or PIR tapered insulation (laid to falls)	Bauder PIR FA-TE insulation is a rigid urethane foam insulation faced on both sides with aluminium foil.  Bauder PIR tapered insulation provides falls to a roof instead of incorporating into structure.
4 BauderTEC KSD Mica	Tear resistant, aluminium lined self-adhesive bitumen air & vapour control layer.

Key features and benefits

Bauder Torch-Free Detailing Methods 

Our 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'
