Aluthermo RoofReflex®

A revolutionary new insulating air-tight breather membrane manufactured with Novia Reflex to improve U Values

Product Overview

RoofReflex® is a hybrid roof and wall breather membrane combined with an insulation layer and CE approved to EN-13859

It offers superb performance and provides a unique set of key product characteristics which include roof and wall dual application approval, excellent soundproofing properties, up to 1.47 additional r-value and a low emissivity surface. 

There are also lower installed costs than PIR when installed in combination with mineral/glasswool.  The insulation is manufactured using hydrophobic and self-extinguishing polyester fibre and is created out of recycled material. The combined product has an E-fire rating.

RoofReflex® is highly moisture vapour open but still remains 100% air-tight. This design concept helps to keep the heat in while allowing unwanted moisture to leave the building, which saves money and creates a healthy internal living environment. By combining RoofReflex® with a suitable Vapour Control Layer (such as VC2 or VC8 Reflective for example), the internal structure of the walls and roofs is protected from condensation damage, and the U-value of the insulation maintained at an optimum level. RoofReflex also has integrated sealing tapes to quickly and easily maintain the air-tight seal at all joints.

RoofReflex®  edges can be left unsealed . The membrane is LABC and EPC approved, and does not need to be reversed in unventilated cavity applications.  RoofReflex® is also orientated to provide a cooling effect in summer, lowering air-conditioning costs, and keeping the building cooler.
