Sealmaster Fireglaze Tape is a universal medium-pressure intumescent glazing tape, especially developed to satisfy the demand for a dry glazing system for both door and screen fire resistant applications. It is particularly useful when volume expansion, thermal insulation and high temperature durability are required.

This flexible intumescent glazing tape provides excellent high temperature sealing properties. It has been formulated to deliver a unique thermal behaviour comprising the benefits of a volume expansion of up to 10 times its original volume, beginning at 180°C. On exposure to heat, the unique chemical formulation allows the product to retain char stability to 1000°C, far surpassing other comparable products currently on the market.

The unique thermal behaviour of the product and exceptional resistance to thermal erosion allows it to be used with a very broad range of fire glazing systems including 30, 60 and 90 minute applications and beyond. It can also be used with integrity only, semi-insulating and fully insulating fire resistant glazing and for a variety of applications in fire rated composite door systems.

Supplied with a strong adhesive backing for quick and easy installation. The glazing tape can be easily cut with scissors or a sharp knife, so is very easy to fit to glazing beads and other precision dependent applications. Resistant to atmospheric moisture and carbon dioxide, the Fireglaze intumescent tape doesn’t require any additional protection.

Sealmaster Fireglaze Tape can also be used as a glazing liner for fire door or screen apertures, so it has two methods of applications where required. The benefit of using it as both a glazing tape and aperture liner is that when it is used in this combination it forms a thermally resistant “U” shaped protection for the edge of the glazing, aiding both integrity and insulation applications.

This fire rated glazing tape is also available in rigid PVC-u holders for particular applications and is called Sealmaster Fireglaze Plus.

Sealmaster Fireglaze Tape has been specifically developed to achieve reliable fire performance in both BS and EN Standard fire test applications of 30, 60 and 90+ minutes. It is Certifire approved and conforms to CF5428.

Made of graphite and mono-ammonium phosphate, the Fireglaze tape is a 2.5mm thick glazing strip in a grey colour, in standard 2100mm lengths and 10mm to 130mm widths. Please call or email Firewise at +44 (0) 1223 839 727 or [email protected] for other sizes.
