APPLICATION
-As a rule, DELTA®-TRELA (PLUS) is installed parallel to the eaves on adequate deck supports (timber formwork, wood-based panels, etc.). The nub structure always points upwards. -The fastening in the overlapping elements is carried out with the DELTA®-DICHTNAGEL (sealing nail).
ADVANTAGES
TESTED FIRE PROTECTION
DELTA®-TRELA (PLUS) is tested as a roofing with metal coverings made of titanium zinc which is resistant to flying sparks and radiant heat (AbP P-BWU03-I-16.3.243 MPA of the University of Stuttgart).
LOW FRICTION RESISTANCE
Due to the high density of the knobbed structure, the shares can slide without any hindrances in case of thermal changes in length.
MOISTURE CAN DIFFUSE OUT
The vapour-permeable carrier track (with an Sd value of approx. 0.02 m) ensures that residual moisture from the construction can safely dry out.
REDUCTION OF CRACKLING NOISES
The crackling noises caused by rain and hail are reduced by up to 15 dB (tested by the test certificate issued by the Scientific and Technical Building Centre in Brussels, Belgium). As a consequence, the product DELTA®-TRELA (PLUS) contributes to the increase of the living comfort.
SEPARATION LAYER, PRE-COVERING, AND DRAINAGE LAYER IN ONE
The 8 mm high tangled fibre nub mat of the track guarantees that the underside of the metal covering is separated from the substructure and moisture can be safely drained. The nub structure as a drainage layer reliably dissipates moisture by preventing corrosion (white rust formation). This ensures the longevity of the high-quality roofing.
