Vitaseal 600 Expanding Foam Tape,use the drop-down menu's to select the gap size you need to fill and then the widths available for that size.

We can cut any gap size tape to almost any width on a 3 - 5 day delivery time please call for pricing.

Vitaseal 600 is a BBA certified expanding foam tape used for sealing gaps around windows, it can also be used to seal other construction gaps 

Vitaseal sealing system expands to perfectly fill these voids with 600P a minimum water tightness, airtightness, thermal and acoustic insulation properties.

Ideal for passive and energy-efficient development and window refitting. At high compressions, the Vitaseal tape is also airtight. At lower compressions, the tape offers a storm-proof weather seal, thermal barrier, acoustic barrier and dust and insect seals. Vitaseal is also recognised for its flame retardancy.

Vitaseal 600 is supplied precompressed by 85%.  


Price is per roll

Vitaseal 600 expanding joint sealing tape is recommended for use in more extreme weather applications (tested to DIN 52453 Watertight Against Driving Rain) and is fully resistant to UV.

This expanding foam tape is supplied in rolls, pre-compressed to approximately 85%.

Vitaseal 600  will expand from its compressed state to fill a gap once unwound and applied. The decompression takes an average of three hours in ambient temperatures, and longer in colder conditions. Tapes are described by three numbers the first is the tape width e.g. 20mm the second two numbers e.g 7-12mm indicate the inclusive gap size at which the tape will be held under sufficient compression (hence the name compression tape) to perform to its maximum fulfilling all three of the possible functions as explained below.

It is ideally suited for closing gaps between window frames and aperatures during installation to create a perfect primary or secondary seal either vertically or horizontally between brick, concrete, stone and insulation panels as well as to metal cladding systems, curtain walling and skylights.

Compression protection values from uncompressed to 75% compressed:

0%   no compression   -   Protects against the ingress of Dirt, Leaves + Insects.

30% compressed         -  Air flow, Dust + all the above values. 

50% compressed         -  Thermal loss, Acoustic transmission, + all the above values.

75% compressed         -  Driving rain, + all the above values.

Vitaseal is an open cell polyurethane foam, impregnated with chemically stabilized acrylics and backed with a high performance acrylic adhesive. It remains permanently elasticand has excellent resistance to UV, mildew and ageing and will not crack, split, bleed or dry out whilst performing throughout continuous movement cycles.

Vitaseal 600 can be painted with any water based acrylic or latex paint and being non-migratory, it is compatible with most caulking materials.

Instructions for use

  • Check whether it is possible to use joint tapes.
  • Clean edges of the joints and check that they are parallel (max. 4°).
  • Find the joint width taking into account the movements of the structure.
  • Select the appropriate joint tape.
  • Cut off the starting and end piece and add 1 cm of tape to each metre of joint.
  • Fit from bottom to top, secure the tape with wedges if necessary.
  • To regulate the delayed expansion:
  • Rolls can be warmed in winter and cooled in summer.
  • Compress strip goods mechanically down to the required compression level.
  • Affix the tape to the edge of the joint with a little back displacement (1 – 2 mm).
  • If the joint edges are wet, secure the tape every 20 cm with wedges.
  • Do not place the tape around corners – use butt joints.
  • Cross and T-shaped joints: Vertical joint overlaps horizontal joint, run the vertical joint right through.

Adhesion instructions: The self-adhesion may cause problems in very narrow joints and may be neutralised temporarily with a little water. Prefabricated concrete components and other heavy elements must be installed using the appropriate spacers.

  • Secure the tape residue with adhesive strips and store flat.
  • The expansion time and capacity depend heavily on the storage time and tape age.
  • Position the self-adhesion downwards on horizontal joints.
