The primary function of SWS INSIDE products is to improve the overall airtightness of the window or door connection joint. There are multiple products within the SWS range that help improve airtightness and vapour retardance of connections. Prevent uncontrolled air flows from the outside and create a vapour barrier to slow down the infiltration of internal moisture into the functional layer.
Liquid membranes are a liquid-based coating that cures to form a rubber-like waterproof and airtight membrane over connection joints. Soudatight LQ and Soudatight SP are high performance product, part of the SWS system. These specialist liquid applied membranes are ideal for internal use to achieve airtightness of any joint or connection. The Soudatight product range consists of multiple pack formats, ensuring suitability for any size of project or application type (e.g. spray or brush applied).
Soudatight LQ is a fibre-reinforced polymer membrane that forms an air- and vapour-tight elastic layer after drying. Easily applied with a brush on most mineral substrates, it fills cracks up to 5 mm. Once dry, it can be painted or plastered. The black version changes from blue to black when dry, while the white version remains unchanged.
Soudatight SP is a sprayable airtight liquid membrane for fast, economical application on large surfaces and connections (floor to wall, wall to ceiling, etc.). It forms an elastic, air- and vapour-tight membrane after drying, providing a solid base for paint or plaster. Apply with professional airless spraying tools for optimal results, and combine with Soudatight LQ for best performance.
Multi-functional joint sealing tapes for making airtight connections between vapour barrier foils and all types of building substrates. Soudal’s SWS window tapes offer versions for both internal and external use, with the option of self-adhesive backing for connecting to the building envelope. The SWS inside tape range consists of two options, with a standard and extra version.
Airtight, damp-proof membrane for interior window-to-wall joints, plasterable on both sides. Self-adhesive on the window side with a butylene strip for initial bonding. Use Soudafoil 330D or 360H for full surface bonding.
Airtight, damp-proof membrane for interior window-to-wall joints, plasterable on both sides. Self-adhesive on the window side with a butylene strip for initial bonding. Full surface adhesive layer on the reverse side for connecting the tape to the building envelope.
Pre-compressed tapes are foam-based tapes that are rolled up and compressed, designed to expand upon application into a joint or gap. This expansion creates an airtight, weather resistant and well-insulated seal between the window frame and the building envelope. Soudal offers a comprehensive range of joint sealing tapes in various dimensions and specification.
Soudaband PRO MF1 is a premium multifunctional joint sealing tape meeting DIN 18542:2020 MF1 standards. It provides a complete SWS sealing system in one product: driving rain-tight up to 1050 Pa outside, good thermal and acoustic insulation in the middle, and airtight inside of the joint. Ideal for durable, long-lasting external joinery seals.
A sealant is a substance used in construction to seal joints between building materials, such as window and door connections. Sealants are an important part of the building envelope, with a wide diversity of sealants available on the market, each with very specific charateristics and properties. As a leading expert in sealants, Soudal can always offer the right product for any application.
