ONDULINE UNDERTILE SYSTEM - CONSTRUCTION BENEFITS:

Reduced roof pitch

Allow tiles to be fixed bellow manufacturer’s minimum pitch by providing assured secondary weathering below the primary roof covering.

Immediate weather protection

ONDULINE UNDERTILE SYSTEM is quick to install, requires no special equipment or skills, and provides immediate weather protection to the building prior to fixing tiles.

Ventilation

The corrugation of the undertile sheets supply ventilation space above the sheet into the batten cavity, and below into the roof space. This significantly enhances roof ventilation.

Moisture protection

With the battens and fixing positioned above moisture flow line in the base of corrugations, excellent moisture control is achieved in the batten cavity.

Thermal insulation

The provision of an ONDULINE UNDERTILE SYSTEM deck in practice significantly improves the thermal performance of the roof structure.

Sound insulation (27%)

The ONDULINE UNDERTILE SYSTEM provides a 27% reduction in sound penetration through the roof covering.

Protection

ONDULINE UNDERTILE SYSTEM significantly reduces the risk of expensive consequential damage to the building and interior as a result of damage to the roof through storms or vandalism.
