Novia Black Breather Membranes are designed and approved to be installed as breather membranes in both roof and wall applications by meeting EN 13859-1 and EN 13859-2. This technical datasheet download highlights the 2 standard Novia Black breather membranes in 115GSM and 146GSM weights. The 115GSM option has been tested to BS 5534 with the results and wind map available in the datasheet. Both membranes should be installed using Novia Breather Membrane Lap tape to ensure an external airtightness barrier is achieved.

Novia Black High Performance Construction Wrap is a 2.7m wide breathable membrane suitable for use in both roof and walls. The 95GSM product is a 3 layer laminate making it one of the strongest style of wall wrap breather membranes available in the construction industry. It is CE approved to both EN 13859-1 and EN 13859-2. This membrane is ideal for all frame constructions such as timber or metsec.

In this collection of technical datasheets, there are the core BS 1521 Building Papers; A1F, B1F, B2 and Polybit ( a polythene coated A1F). Novia Ltd are the UK leading supplier of BS 1521 Building Papers, supplying all varieties to a wide range of users. Each building paper has its own characteristics and uses, so ensure that you select the correct one when planning your project.

Using tapes when installing membranes is becoming increasingly important. Novia membranes should be installed using our 2-tape system throughout to ensure airtight and vapour tight installations. This catalogue of the range of Novia tapes highlights the options available to the installer. For breather membranes, our Breather Membrane Lap tape and Double Sided Adhesive Tape should be used in conjunction with each other to create an external air leakage barrier. For internal (vapour control layer) tapes, our double sided butyl tapes are available in varying widths and lengths to suit the installer, and should be finished with our metallised BOPP tape on the overlap to achieve an air and vapour tight seal.

Novia Polythene Vapour Control Layers (VCL) are highlighted in this datasheet bundle. Novia 500, 1000, and 1200 Gauge virgin polythene VCLs will each offer a different moisture resistance due to the varying thicknesses. 500G is more suitable for a residential property, whereas the 1200G is more commonly found within commercial or industrial applications. All of Novia VCLs are CE Approved to EN 13984:2013.

Novia Reflex Breather Membrane is a reflective breather membrane that is suitable for use on both roof and wall applications. The membrane is CE approved to EN 13859-1 and EN 13859-2. The membrane can improve insulation calculations by utilising the highly reflective surface within a 25mm airgap. Novia Reflex will also act as an external airtightness barrier.

Novia STRP Vapor Barrier is a reinforced polythene membrane with a flame resistant coating added. The translucent design allows easier installation to help ensure all seals and laps are completed to have an air-tight installation. Novia STRP is commonly installed in industrial and commercial properties and is CE Approved to EN 13984 as a vapour control layer.

Novia VC2 is reinforced air-tight vapour check membrane suitable for use in all insulated wall, roof and floor applications. The membrane should be fully taped when installed to prevent any air leakage which will help in making the construction more efficient without loss of heat through gaps. With a low SD value and low water vapour permeability, Novia VC2 is ideal for use as a vapour check in residential properties.

Novia® VC200 Reflective is a high performance, reflective and air-tight vapour control membrane. It is designed for use as an air leakage barrier and vapour control layer (AVCL) for use in insulated wall, roof and floor applications requiring high moisture resistance.
