Viking Halley-P NO FLAME

Viking Halley-P NO FLAME is a self-adhered two-layer membrane system — the newest member to Viking Roofspec's bituminous membrane category. 

Manufactured by General Membrane sPA who produce Viking's torch-on membranes, the Halley-P NO FLAME employs a special bitumen and adhesive resin mixture that allows the membrane layers to be installed without the use of a propane gas torch. Halley-P NO FLAME is a hybrid of two compounds: a plasticised APP bitumen mixed with a rubberised SBS one. The 'NO FLAME' aspect comes from the lower surface and the selvedge edges consisting of an elastomeric pressure-sensitive adhesive. This membrane system’s quality is highlighted by two indicators: its low temperature flexibility (-25°C) and the adhesive’s compatibility to a wide range of substrates. The adhesive’s properties facilitate installation in a wide range of climatic conditions.

•Subject to specific structural and weathertightness design situated in wind pressures up to a maximum design differential ultimate limit state (ULS) of 6 kPa: and,

•With substrates of plywood or suspended concrete slab


Limitations on Use

Viking Halley-P NO FLAME has been designed to be installed in any climate zone due to its hybrid blend of APP and SBS modified bitumen compounds.

The system must be installed by a Viking Roofspec Trained and Approved Installer.
