PREMIUM ALUMINIUM BUTYL SEALING TAPE
SEAL THE GAP.
SKIP THE HEAT.
A joint needs sealing. Not a burner.
Aluminium-faced butyl tape that adheres without heat activation. Prepare the surface. Peel. Press.
50 mm WIDE 5 m / 20 m ROLLS
ILLUSTRATIVE APPLICATION01 / START AT THE WEAK POINT
A SMALL OPENING.
A BIGGER PROBLEM.
A loose overlap. An open joint. An unfinished edge. Before you cover the detail, find where water can travel — and make sure the base is sound.
Find the actual entry point.
Not just the visible stain.
Remove what stops contact.
Dirt is not a bonding surface.
Plan the seal around the detail.
Leave heat activation out of it.
02 / KNOW WHAT YOU ARE PUTTING DOWN
ALUMINIUM
OUTSIDE.
BUTYL AT
THE BOND.
Two materials. Two roles. The aluminium face sits on the outside. The butyl adhesive makes contact with the prepared surface.
- Aluminium face
- The silver outer layer.
- Butyl adhesive
- The self-adhesive sealing layer.
- Release liner
- Removed during installation.

THE DIFFERENCE IS IN THE APPLICATION
NO HEAT
ACTIVATION.
The adhesive is ready to make contact. You do not need to heat it first.
Cold-applied describes the process. It does not mean every surface or application temperature is suitable.
03 / A DIFFERENT INSTALLATION PROCESS
REMOVE THE
HEATING STEP.
NOT THE PREP.
Compare the application steps before choosing a repair method. The joint still needs to suit the selected tape or system.
| On the job | FasVix Premium | Torch-applied system |
|---|---|---|
| Adhesive contact | Peel, position and press | Heat underside and substrate |
| Heat activation | Not required | Part of the specified process |
| Preparation | Required | Required |
| Detail design | Confirm for the local repair | Follow the system specification |
Process comparison only, not a claim of equal performance or full-system replacement. Some bituminous products are also self-adhesive. Application reference [3]
04 / START WITH THE DETAIL
THE SEAM.
THE OVERLAP.
THE EXPOSED EDGE.
Roofing, drainage, pipe and window details are the starting points in the FasVix catalogue. The right choice still depends on the exact surface and conditions.

GUTTER & DRAINAGE DETAILS
THE JOINT
DESERVES
A CLOSER LOOK.
Inspect the lap, remove loose material and establish continuous contact. A strip resting over a gap is not the same as a well-fitted sealing detail.
Check your applicationRoof seams
& flashing
Assess the overlap, coating and water path before laying the tape. Roof access and the overall condition of the detail still need attention.
Pipe & window
details
Identify the material on each side of the joint. Confirm compatibility, required coverage and the exposure the completed detail will face.
Application photos are generated illustrations, not evidence of a tested FasVix installation. Confirm the selected article and method for the job.
05 / THE PART YOU CANNOT SKIP
CLEAN SURFACE.
FULL CONTACT.
CAREFUL EDGES.
No burner does not mean no preparation. The work is in the surface, the fit and the pressure.

- 01
Check. Clean. Dry.
Confirm the substrate and application conditions. Remove contamination and loose coatings. Resolve moisture or condensation before applying.
- 02
Plan the coverage.
Measure the detail. Cut the required length and plan the edges and overlaps according to article-specific guidance.
- 03
Peel. Place. Press.
Remove the liner progressively, position the tape and press it into close contact. A suitable hand roller helps work across the detail.
- 04
Inspect the edges.
Look for lifted edges, folds and trapped air. Follow the installation guidance and assess the completed repair before putting it into service.

08 / ASK BEFORE IT GOES ON THE JOB
NO GUESSWORK
AT THE JOINT.
Cold application is clear. Suitability is specific. Start with these questions.
Do I need to heat the tape before applying it?
No. FasVix Premium is a cold-applied aluminium butyl sealing tape: its adhesive does not require heat activation. Remove the release liner, place the tape on a prepared surface and press it into full contact. Confirm the installation conditions for your selected article.
Does cold-applied mean it works in freezing conditions?
No. Cold-applied describes the method, not an unrestricted temperature range. Surface temperature, frost and condensation still matter. Ask for the FasVix application-temperature guidance before planning cold-weather work.
Can I put it straight onto a wet or dirty surface?
Prepare a clean, dry, sound surface first. Dust, grease, loose paint and moisture can interrupt adhesive contact. Identify the cause of the leak and dry the bonding area before applying the tape.
Which materials can I use it on?
The exact material and its finish matter. Tell us whether you are sealing metal, a coating, masonry, a membrane or another surface. Check compatibility and trial adhesion first. Porous or dusty substrates may need additional preparation or a suitable primer.
Why do I need to press or roll it?
Pressure brings the adhesive into close contact with the surface. Work over the tape, its edges and changes in shape so it is not simply resting across the detail. Avoid folds and trapped air; follow the selected article’s installation guidance.
Can it fix a pressurised pipe or work underwater?
Do not assume so. A surface sealing detail is different from containing pressure or remaining permanently submerged. Those applications need explicit product approval; ask before choosing the tape.
Is this a replacement for a complete roofing system?
This page concerns local sealing details, not a complete roof specification. Repeated leaks, damaged substrates, larger areas or an uncertain water-entry point should be assessed before a repair method is selected.
Are the two roll lengths otherwise identical?
Both listed articles are 50 mm wide and belong to the premium aluminium butyl range. Do not assume that every construction detail is identical. Request article-specific technical information when selecting or switching between the 5 m and 20 m formats.
