Timbertex Airtight Control Barrier protects the construction from condensation caused by diffusion. It ensures a controlled and regulated diffusion of water vapour through the thermal insulation. Like all of Isocell's membranes products it is extremely durable. Due to its strength it can be used as a retaining airtight membrane for blown in insulation. Air-Sealing with: Airstop Flex Adhesive Tape, Airstop Adhesive Tape, Airstop Sealant Sprint. Please follow our product guidelines.

A moisture-variable vapour barrier for use in the air-tight layer. The functional membrane changes its diffusion resistance depending on the current humidity. During the winter months room atmosphere is generally dryer. The sd-value of the vapour barrier increases. This process results in the penetration of only a little water vapour into the construction and/or into the insulation. In summer, when there is sufficient solar insulation, the relative humidity behind the membrane is higher as a result of reverse diffusion. The water molecules are stored in the membrane. The sd-value sinks, causing more water vapour to escape from the construction and into the rooms and the building element becomes dryer.

Airstop Diva Forte Variable/Intelligent Membrane. Airstop Diva Forte reacts to ambient humidity. During the winter months the pores of the membrane decrease in size, preventing hot, moist, heated air from passing through the membrane into the insulation, therefore ensuring the effectiveness of the insulation and protecting your structure from damage due to excessive moisture. During the summer months (drying-out months), due to ambient humidity and temperatures, the pores of the membrane increase in size, therefore allowing any potential moisture within the structure, to dry back out towards the inside of the dwelling, hence preventing possible mould and rot within the structure. This process is crucial for exterior elements which are non-vapour diffusing or restrict the drying out of moisture to the exterior, such as felt-torched or water proofed flat roofs, pitched roofs with asphalt shingles, and green roofs. The variable vapour permeability of Airstop Diva ranges from 0.2 to 20, offering the highest protection against moisture related damages on the market.Air-Sealing with: Airstop Flex Adhesive Tape, Airstop Adhesive Tape, Airstop Sealant Sprint.

A transparent vapour barrier for the airtight layer in roof and wall constructions. In general FH Fleece Vapour Barrier is suitable for use in building components that are non-vapour retardant on the outside. Air-Sealing with: Airstop Flex Adhesive Tape, Airstop Adhesive Tape, Airstop Sealant Sprint.

AIRSTOP 1500 Vapour Barrier is an extremely tear-resistant vapour barrier for use in the air-tight and vapour-tight layer in roof an wall constructions. When professionally installed it can prevent the ingress of vapour into the construction even where there is very high moisture load. Air-Sealing with: Airstop Flex Adhesive Tape, Airstop Adhesive Tape, Airstop Sealant Sprint.

A transparent, extremely tear-resistant vapour barrier and airtight layer for wall, roof and ceiling constructions. Easy to handle, its extreme tear resistance allows it to be used in environments that may require additional strength. Its transparency allows easy application as well as identification of fixing points such as rafters, steelwork for following on trades. Air-Sealing with: Airstop Flex Adhesive Tape, Airstop Adhesive Tape, Airstop Sealant Sprint.

Öko-Natur is a fabric-reinforced paper vapour barrier and air-tight membrane for roof, wall and ceilings that are vapour permeable towards the outside. The fixed Sd value ensures a regulated release of vapour through the barrier, ensuring the effectiveness of the insulation whilst protecting your structure from damage due to excessive moisture, therefore preventing possible mould and rot. This is an environmentally friendly recyclable fabric reinforced membrane, ideal for eco-friendly builds. Air-Sealing with: Airstop Flex Adhesive Tape, Airstop Adhesive Tape, Airstop Sealant Sprint. Regulates moisture

Used as a vapour barrier and airtight layer on wall and roof constructions. High tear resistance due to its integrated fabric mesh reinforcement.

Airstop VAP Vapour barrier is a quality vapour barrier sheeting and airtight layer of flame-retardant polyethylene for non-vapour retardant roof, wall and ceiling constructions. Air-Sealing with: Airstop Flex Adhesive Tape, Airstop Adhesive Tape, Airstop Sealant Sprint.
