Novia Reflex Reflective Roof and Wall Breather
Our UKCA certified, dual approved reflective breather which meets EN 13859-1 (roofs) and EN 13859-2 (walls).
Product Overview
Novia® Reflex Roof and Wall Breather is a high quality, strong, versatile, low cost reflective breather membrane for all pitched cold and warm roofs, as well as insulated wall applications. The material is UKCA certified and meets EN 13859-1 for pitched roofing and EN 13859-2 for walls. Novia® Reflex meets EN 1928 Class W1 water resistance, but still provides high breathability.
Novia® Reflex has a reflectivity of 81% (aged), which will improve the constructions U value. When correctly installed, it is possible to achieve an additional r value of up to 0.45 m²K/W in an unventilated wall cavity, or up to 0.17 m²K/W in an insulated sloping roof. Additionally, the reflective face allows the construction to remain cooler in summer and warmer in winter. Novia® Reflex has excellent tensile and nail tear strength, offering improved durability when handling on site and reducing the risk of accidental damage during installation. The product is reflective on one side, white on the reverse, with no text or images, except for a 150mm overlap line.
Novia® Reflex is suitable for use in BS 5534 wind uplift applications. Following successful tests, Novia® Reflex can be used with a ≤ 345mm batten in zones 1-2 without additional tapes, and in zones 1-5 using our Breather Membrane Lap Tape.

Installation Tips
We strongly advise the use of Novia installation tapes, even if tape is not specified for mandatory use within a particular zone under the BS 5534 wind uplift test results. The use of tapes will greatly improve the performance and overall airtightness of the roof structure. We offer a single-sided Novia® Breather Membrane Lap Tape (BMLT) for basic installations and for high specification work, where there is even greater emphasis on air-tightness, we offer the optional Novia® Double Sided Lap Tape (DSLT). For the very best standards of installation and air-tightness, we advise the use of both types of tape, which will ensure a long lasting, high quality, breathable and air-tight seal is formed.
