THERMAFLEX textile tape grey 25 m x 48 mm — adhesive insulation/repair tape

THERMAFLEX textile tape in grey, 25 m long and 48 mm wide, is a woven cloth tape with a pressure-sensitive adhesive backing designed for insulation, sealing and repair applications. The tape combines cloth flexibility with adhesive performance to allow neat wrapping around joints and irregular shapes, secure insulation materials and provide temporary fixes on surfaces exposed to maintenance or installation work.

Advantages

The cloth construction ensures tear resistance and conformability, making the tape easy to apply by hand and able to follow contours. The pressure-sensitive adhesive provides reliable initial tack and holding power on common construction materials such as insulation foams, metal ducts, pipes and textiles. Grey colour offers a neutral appearance for visible areas while the 25 m roll length reduces the need for frequent replacements on the job.

Suitable for

• Wrapping and sealing joints in HVAC ducting and insulation systems
• Securing insulation on pipes and fittings
• Temporary repairs and surface protection during installation or maintenance
• Bundling and holding cable runs or lightweight components

Key specifications

• Material: woven textile cloth with pressure-sensitive adhesive
• Colour: grey
• Length: 25 m
• Width: 48 mm
• Construction: flexible, tear-resistant fabric

How to use

Ensure surfaces are clean, dry and free of dust, oil or loose particles before applying the tape. Measure and cut the required length, then press the adhesive side onto the surface while smoothing to remove air pockets. Overlap turns slightly when wrapping joints or insulation to ensure continuous coverage and sealing. For curved or irregular shapes, stretch lightly and conform the tape by hand to maintain contact with the substrate. For long-term or load-bearing fixes, use in combination with mechanical fasteners or specialist adhesives as appropriate.

Usage recommendations

Store rolls in a dry, cool place away from direct sunlight and high humidity to preserve adhesive properties. Test adhesion on small area when using on painted surfaces or sensitive materials to avoid lift or damage.
