Product Description

Our entry grade synthetic 3-layer laminate utilising a microporous breathable polymer. For use as an ultra-low-cost roof underlay and as a high quality wall-cladding on timber frame constructions.

Novia Ultra is an entry-grade, versatile, dual approved and ultra-low cost breather membrane for use in pitched cold and warm roofs, and insulated wall applications. The material meets EN 13859-1 for pitched roofing and EN 13859-2 for walls. The product has good water resistance, high breathability, and is lightweight and easy to handle. Novia Ultra is coloured light-grey on one side and white on the other, but with no text or images on either side, except a 150mm overlap line. For higher specification applications, please refer to Novia Black or Novia Reflex breather membranes.

Novia Ultra has been introduced to comply with new mandatory CE marking requirements, introduced under the 2013 Construction Products Regulations. Under this new European directive, all products covered by a current hEN must comply with the new standard. Third party accreditation alone is no longer suitable. All breathable membrane products manufactured after the implementation date in July 2013 must conform to the new CPR standard.

Installation guide

Walls: Fix the membrane to the wall structure; ensure upper layers overlap lower layers. Work from the bottom moving upwards and ensuring there are minimum overlaps of 100 mm on the horizontal joints. Do not begin a vertical lap joint within 300mm of a corner, and vertical laps should be at least 150 mm. Ensure the bottom timber is also protected by an overlap. Fix at suitable intervals with galvanised nails, stainless staples or similar fixings that will be permanent.

Do not leave the membrane unnecessarily exposed to weathering as high winds, excessive UV etc. may cause damage over time. If you must leave the membrane exposed for extended periods of time, consider the use of suitable temporary protection materials.

Roofs: Novia Ultra can be installed within both warm and cold roofs. On insulated warm roofs the membrane may be placed directly onto the insulation. Novia Ultra can also be used in conventional cold roof applications. Novia Ultra is unsuitable for fully boarded roof applications.

Fix the membrane to the roof structure; ensure upper layers overlap lower layers. Work from the bottom moving upwards and ensure there are minimum overlaps as shown below.
