Sarnafil® T 66-15 D
Sarnafil® T 66-15 D is an unreinforced multi-layer, synthetic roof waterproofing sheet based on flexible polyolefins (FPO). Sarnafil® T 66-15 D is a hot air weldable, UV-resistant roof detailing membrane.
- Resistant to permanent UV exposure
- Resistant to most common environmental influences
- Resistant to micro organisms
- Resistant to old bitumen
- Hot air welding without use of open flame
- Can be applied on either side as both surfaces have a different colour
- Recyclable (Delete if recycling facilities or recycling offerings for roofing membranes are not available in local country)

System Structure
The following products must be considered for use depending on roof design:
- Sarnafil® T Metal Sheet
- Sarnabar

Compatibility
Sarnafil® T 66-15 D may be installed on all thermal insulation types and levelling layers suitable for roofing. No additional separation layer is required. A fire protection layer maybe necessary. Sarnafil® T 66-15 D is suitable for installation directly on top of existing, cleaned, level bituminous roofing, e.g. re-roofing over old flat roofs. Colour changes in membrane surface may occur if in direct contact with bitumen. If existing roof build up needs to be removed, Sarnafil® T 66-15 D can be adhered directly on to the bituminous vapour control layer for partitioning and protection of the day work.

EQUIPMENT
Hot welding overlap seams
Electric hot air welding equipment, such as hand held manual hot air welding equipment and pressure rollers or automatic hot air welding machines with controlled hot air temperature capability of a minimum 600 °C.
Recommended type of equipment:
Manual: Leister Triac
Automatic : Sarnamatic 661/681
Semi-automatic: Leister Triac Drive
SUBSTRATE QUALITY
The substrate surface must be uniform, smooth and free of any sharp protrusions or burrs, etc. The supporting layer must be compatible to the membrane, solvent resistant, clean, dry and free of grease and dust. Metal sheets must be degreased with Sarnafil® Cleaner before adhesive is applied.
APPLICATION
Installation procedure
Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions.
Reference must be made to the Installation Instructions: Sarnafil® T roof systems.
Fixing Method
Perimeter mechanical fixing:
Sarnabar including Sarnafil® T Welding Cord which must be used to keep the membrane in place.
Adhered roof junction areas and flashings:
Sarnafil® T 66-15 D is adhered to substrate layers such as concrete, render, timber panels, metal sheets, etc. use contact adhesive Sarnacol® T 660.
Overlap seams:
Seams are hot welded using specialised hot air equipment. The effective width of welded overlaps must be a minimum of 20 mm.
Hot welding method
Overlap seams must be welded by electric hot welding equipment. Welding parameters including temperature, machine speed, air flow, pressure and machine settings must be evaluated, adapted and checked on site according to the type of equipment and the climatic conditions prior to welding.
Testing overlap seams
The seams must be mechanically tested with screw driver or steel needle to ensure the integrity/completion of the weld. Any imperfections must be rectified by hot air welding.
