Pro Clima Aerosana Visconn Fibre
Pro Clima Aerosana Visconn Fibre
Fibre reinforced airtight liquid membrane
Fibre reinforced liquid airtight sealant for sealing where the gaps, at critical junctions or between building components, are upto 20mm wide.
Use it on
Brickwork, blockwork, concrete, timber, wood based panels (including wood-wool boards), sheathing and cement particle boards.
Aerosana Visconn Fibre is a flexible liquid-applied fibre-reinforced air barrier for use as a gap filling sealant. It is suitable for sealing gaps of up to 20mm in width to form an elastic robust vapour retarding seal.
Where to use it
Aerosana Visconn Fibre can be used at critical junctions such as: wall to ceiling, wall to floor as well as connection between building components. It can be used when the gaps are up to 20mm in width. Perfect for where gaps are too wide be sealed with Aerosana Visconn; which is only suitable for gaps of up to 3mm.
Commonly used on masonry brick and block builds to fill gaps, cracks or missing areas of mortar joints and at junctions to window and door reveals.
What it does
Visconn Fibre offers a robust long-term flexible seal that can be paint applied to fill gaps of up to 20mm in width. It is an easy-to-use, quick and cost effective alternative to taping, and can be combined with the complete range of Pro Clima airtight tapes and grommets (once it has fully dried).
It is applied by brush in a thick fibrous blue coating and turns black once dried, forming a flexible seal which fills gaps of up to 20mm in width.
How it works
The thick fibre- reinforced liquid of Visconn Fibre works by filling gaps and cracks and eliminates any unwanted air leakage. It is an ideal solution for common tolerance gaps around windows and doors rather than using expanding foam sealants. It creates a long-term flexible seal on the airtight connections of various substrates.
Why we love it
Aerosana Visconn is an excellent versatile connection sealant that can be used in a variety of junctions and hard to access areas or where application of tapes membranes or other sealants would prove too cumbersome.

Key Technical Data
How to Install
The condition of the substrate needs to be reviewed prior to the application of the Visconn Fibre. Some areas of gaps and larger cracks may require additional coats during application. If the substrate is rough or friable and unstable in any way, this area needs to be made good.
All surfaces should be clean, dry and any flaky unstable material brushed off and wiped clean or cleaned using compressed air. Visconn Fibre should not be applied in areas where water repellent grease or silicones have been applied. Application to frozen surfaces is not possible, use only in temperatures of above 5 degree Celsius.
Ensure the product is thoroughly stirred before use.
Once Visconn Fibre has been applied and allowed to dry; it can be integrated into plaster or standard Aerosana Visconn to ensure a continuous, fully airtight, robust and flexible long term airtight solution around these openings.
Hints and Tips
When filling gaps, guide the brush flat across the crack so that the gap becomes completely filled.
It can be used as alternative to Contega Solido SL tape to seal around window and door frames, as it seals gaps of up to 20mm, a common width between window/doors and the surrounding masonry reveals.
