TEMFOIL SA30B Matt Black Aluminium Foil Tape is a high-performance foil tape designed for sealing and finishing joints and seams in internal HVAC ductwork and mechanical insulation applications.
Made from a 30 micron matt black aluminium foil with a rubber pressure-sensitive adhesive and release liner, it provides strong adhesion, good moisture resistance and a clean, discreet finish where standard bright aluminium foil tape may be too visible.
Its matt black appearance makes TEMFOIL SA30B particularly suitable for exposed internal ductwork, dark-finished HVAC systems and insulation installations where a more professional, low-visibility finish is required.
Key Benefits
- Matt black finish – ideal where standard silver foil tape would remain visible
- Strong adhesion for reliable sealing of joints and seams
- Hand tearable for quick and convenient installation
- Moisture resistant in humid internal environments
- Excellent ageing resistance for long-term performance
- Wide service temperature range from -30°C to +120°C
- Suitable for HVAC, ductwork and mechanical insulation applications
Typical Applications
TEMFOIL SA30B can be used for sealing and finishing:
- HVAC ductwork joints and seams
- Foil-faced duct insulation
- Mechanical insulation systems
- Internal duct lagging
- Insulation joints requiring a matt black finish
- Exposed internal HVAC installations
Why Choose Matt Black Foil Tape?
Standard aluminium foil tape provides an effective seal but can remain highly visible on exposed ductwork. TEMFOIL SA30B provides the same practical tape format with a matt black aluminium surface, helping joints blend into dark ductwork, ceiling voids and exposed mechanical services.
This makes it a useful finishing product for contractors working on commercial HVAC systems where both performance and appearance matter.

- Centre the tape over the joint or seam.
- Apply firmly, allowing the tape to conform closely to the surface and contours.
- Use sufficient pressure to achieve maximum surface contact and adhesion.
Important: TEMFOIL SA30B is intended for internal applications only. Tape should be used for sealing joints and seams and is not a substitute for mechanical fixing.
