Onduline launches the only UK waterproofing system guaranteed at a 10o pitch

Onduline, the light weight roofing systems and water-proofing specialist, is delighted to announce the launch of its new and unique under roof system, ISOLINE^® LOW LINE - the only system in the UK to be BRE tested and BBA Accredited to as low as 10^o.

Designed specifically for use on low pitch roofs, this lightweight bituminous

underlay sheeting has been rigorously tested and is proven to be at least three times less likely to leak compared to a traditional tile system.

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.

Not only does this help 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 or large roofing projects, greatly enhancing the aesthetic quality of a property.

Ardit Strica, Technical Manager for Onduline Building Products, said: “We’re delighted to be launching ISOLINE^® LOW LINE, it’s exciting as it is the only under roofing system in the UK that can be used on a pitch as low as 10^o, which is huge for the construction industry.

“Maximising ease of use for the installer was also a key priority for us with the design of this system, with the smaller corrugations of the sheet not only adding rigidity and strength, they also allow for easier fixing and greater compatibility with mechanical fixings for solar panels, which will be key over the coming years.”

Easy to carry, handle and fix, the non-slippery sheets are simple to cut with vertical overlaps embossed into the sheet. This makes installation even quicker and easier as it takes away the need to measure and it also removes confusion when it comes to knowing how much to overlap.

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.

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.
