BRE tested and BBA accredited sub-roof for pitch roofs as low as 10°
Designed specifically for use on low pitch roofs, this lightweight bituminous sub-roof system has been rigorously tested and proven to be at least three times less likely to leak compared to a traditoinal felt system for low pitch roofing.
With a corrugation height of just 24mm, ISOLINE® LOW LINE is fixed below the primary tile or slate roof covering, acting as the primary waterproofing layer of a roof. Thus, making roof tiles a secondary line of defence enabling the pitch of the roof to be much lower than the minimum as recommended by the tile manufacturer.
Increased ventilation
Due to the corrugations, ISOLINE® LOW LINE allows increased ventilation and airflow both above and below the sheet and tile battens positioned above the corrugations allow moisture to drain to the eaves which, with the enhanced ventilation, maintains excellent moisture control within the cavity.
Maximising living space
Also helping to meet the demand for maximising living space, as the low pitch means the roof void can be minimised, it also enables traditional tiles to be used in situations where they wouldn’t have been able to be utilised previously, such as extensions greatly enhancing the aesthetic quality of a property.
Sustainable solution
The material is also in line with the growing awareness of ‘green’ issues and the need to offer sustainable solutions as ISOLINE® LOW LINE sheets are made of a minimum 50% recycled cellulose fibres, contain no asbestos and do not release any hazardous substances
