​​​A fire seal fit for any pipe ​
A little maintenance goes a long way

​​Fire seals for penetrations through fire rated walls are essential. Which is why it’s so devastating when contractors fail to install them because the correct size isn’t in stock or at hand. A flexible fire seal from Kaimann offers what just might be the solution for hundreds of fire safety consultants & contractors.

​​Traditionally many consultants have specified fire collars or sleeves to be placed around pipes as they penetrate the fire rated wall. These fire sealing measures are sized to fit around an exact size of pipe with a pre-defined thickness of insulation applied.

​​If a contractor finds any slight deviation from the plans when they arrive on site it’s likely to mean a trip straight back to the wholesaler to buy another collar. If the wholesaler has the alternative size in stock.

This necessity to stock a vast range of different sizes has meant that non-specialist wholesalers have historically struggled to get to grips with fire-protection measures.

One size fits all

​​Kaiflex Pyrostar overcomes the biggest challenge that fire penetration seals face by nature of its flexible roll format. The 1-2 mm thick Kaiflex Pyrostar sheet is supplied in a very compact roll that fits in a 15cm x 15 cm x 15 cm cube box.

​​The Kaiflex Pyrostar sheet has an intumescent additive built-in and will expand to close any gap that may appear in or around the pipe in the event of a fire. Kaiflex Pyrostar is installed by wrapping the sheet around the insulated pipe as it passes through the wall.

A little maintenance goes a long way

Since the sheet is supplied in long rolls and cut to size on site one size really does fit all possible pipe plus insulation system configurations, making it a great product for a contractor to keep on-hand at all times and an easy product for wholesalers to stock without needing to commit to a vast range of fire protection products.​

A more reliable solution

​​The advantages of Kaiflex Pyrostar aren’t simply that it’s a convenient product to stock and install – it’s proven to work as effectively as other fire sealing measures and it overcomes some of the weaknesses of other fire sealing solutions.

In particular Kaiflex Pyrostar has no capability to absorb large volumes of moisture. Ironically water is fatal for any fire penetration sealing solution. This is because, during the early stages of a fire, the thermal energy is expended vaporising the water instead of activating the intumescent that must expand to complete the fire seal.​
