Techseal 21 - Weather seal for Doors

Here at Shop4handles we offer foam filled seals for both doors and windows. Techseal 21 is suitable for doors and is fitted into a purpose groove or kerf, which runs along the jambs and head of the door frame, thus sealing the door completely when shut. Techseal is available in either white or brown finish and in 10 or 250 metre rolls.

Techseal 63 - Weather seal for Windows

Very similar to Techseal 21 is Techseal 63. Techseal 63 has the same application as Techseal 21 but is primarily for windows. Using these type of seals on both doors and windows will dramatically reduce draughts and prevent unwanted heat loss, and in turn lower those energy bills! Furthermore both Techseal seals incorporate a low friction polyethylene outer covering which is impervious to paint and stains, immune to the effects of UV and Ozone as well as water and moisture repellent, which will prohibit the growth of mould and mildew.  The PU foam core will retain its shape year after year as well as withstanding long term use and changes in temperature.

The importance of restricting the spread of fire and smoke within a building has long been recognised. In most buildings there will be a specific exit route in the case of a fire, in order to keep this passage protected in the event of a fire certain doors have to meet with strict fire testing standards. Fire doors will have been tested to hold their integrity in fire conditions of either 30 or 60 minutes. However in many cases some modern doors only meet these requirements with the additional use of an Intumescent fire seal. Considerations regarding the door’s ironmongery also have to be taken into account with regards to the integrity of a door in a fire.

Intumescent Fire Seal

The purpose and role of the Intumescent fire strip is to seal against the passage of fire, smoke and hot gases. The seal is often made from a graphite based substance which when heated to greater than 150 degrees centigrade will activate and swell to many times its original size, thus sealing the gap between the door and frame. This will then reduce the speed of the spread of fire to the rest of the building.

Intumescent Fire & Smoke Seal

The spread of smoke and hot gases can also be a big problem, in fact smoke can be a major cause of death and injury along with being a significant contributor  to the cost of the fire damage. It is therefore imperative that smoke and hot gases are contained in the event of a fire wherever possible. The containment of smoke can be achieved with fire seals which incorporate a brush smoke seal, which, along with preventing the spread of fire also help aid against the spread of smoke and hot gases.

We sell both fire only intumescent strips and fire and smoke intumescent strips suitable for both 30 minute and 60 minute fire door assemblies. They are available in 3 different sizes, 10 and 15mm strips are suitable for most 30 minute fire doors, 20mm are suitable for 60 minute fire doors. They come in either white or brown to suit different door finishes and are quick and easy to install with a self adhesive backing. Furthermore all of the intumescent seals we offer comply to BS476: Part 22: 1987 and BS476: Part 31.1 and are Certifire approved. They are also competitively priced too!
