series  FFD 
expansion roofing joint  (especially suitable to absorb transversal and vertical movements)

Material:
Special soft PVC hot bitumen-resistant, weather and ageing resistant.
Bitumen resistant as for DIN 16937

WATERTIGHT ROOFING JOINT
BOTH COMPATIBLE WITH BITUMINOUS
AND WITH PVC SHEETS



 

Profile to profile welding:

It is possible to realize welding between profiles by a normal resistance heater or by a welder (available on request). Approach the two parts to weld to 2 cm about (head to head), heat them to partial liquefaction, then approach them and keep them pressed some moment. Slight faults of welding can be obviate by lap welding with same material, hot applied by system as over indicated.

Special Properties:

  • Profile has two wings 150 mm wide, with grooved surface for secure adhesion in hot bitumen between bituminous roof layers or in PVC waterproofing sheets.
  • Easy manufacture of angles, T and cross pieces straight in yard.
  • Profile guarantees good resistant to mechanic actions.
  • Profile is right to make a "dielectric" joint
