Intumescent Seals Therm-A-Strip is a low pressure intumescent strip that provides excellent fire sealing properties with the benefit of a flexible strip of intumescent material. The product has been developed for applications where a pressure forming product is disadvantageous. The degree of expansion is moderate in order to provide some resistance to erosion.
This phosphate based intumescent fire strip can give an approximate ten fold increase in volume when exposed to temperature above 180C. When used for 60 minute glazing applications, the fire strip should be used in conjunction with other products to enhance its performance.
Therm-A-Strip can be supplied in a variety of shapes so that it can be used in a wide range of applications including gaskets for ironmongery protection i.e. locks, latches, bolts, hinges etc. It is also useful in applications where the gap to be filled is small and the fire retardant properties are beneficial, such as overpanels. Suitable for use where there is a possibility of localized flaming due to combustible products, since it generates fire retardant gases when heated.
Therm-A-Strip intumescent door strip has been successfully tested as a component of various doorsets to meet the fire resistance performance requirements of BS 476: Part 20 & 22. It has also passed exacting standards required by Certifire.
This intumescent fire strip is supplied in either a natural white finish or a brown colour and because of its resistance to both atmospheric moisture and carbon dioxide, it requires no additional surface protection. The material may be decorated with a wide range of conventional finishes without impairing the performance. It is available without or with a self-adhesive backing strip for ease of installation.
Available as standard in a 2100mm length. However, other thicknesses from 1mm upwards, widths up to 130mm wide and lengths up to 3000mm can be provided upon request, in order to cater for a wide range of applications such as gaskets and ironmongery protection.
