Intumescent strips, also known as fire seals or fire stops, play a crucial role in passive fire protection systems. They are designed to expand and swell when exposed to heat, thereby sealing gaps and preventing the spread of fire and smoke. There are several types of intumescent strips, each tailored to specific applications and environments. Firstly, door intumescent strips are the most common type. These are installed around the edges of doors and frames, expanding upon exposure to high temperatures, ensuring that fire and smoke are contained within the room of origin. They not only provide fire resistance but also enhance acoustic and weatherproofing properties. Secondly, window intumescent strips are used in windows and glass doors. They work similarly to door strips but are specifically designed to handle the unique challenges of glass expansion and contraction. When a fire breaks out, these strips, forming a barrier that seals the gap between the window frame and the building structure. Thirdly, cable and pipe intumescent strips are employed to seal openings through which cables, pipes, or ducts pass. These strips ensure that even if fire breaches one part of the structure, it cannot spread through these conduits.

types of intumescent strips. Fourthly, perimeter seal intumescent strips are used in curtain wall systems. They provide a fire-resistant barrier around the perimeter of the curtain wall, where it meets the floor, ceiling, or other walls. This type is particularly important in high-rise buildings. Lastly, intumescent strips for HVAC (Heating, Ventilation, and Air Conditioning) systems are designed to protect ventilation ducts. They in a fire, sealing off ducts and preventing the spread of flames and toxic smoke through the ventilation system. Each type of intumescent strip is made with specific materials and formulations, depending on the required fire resistance period and environmental conditions. The choice of strip depends on factors such as the potential fire risk, the building's construction, and the purpose of the area it will protect. In conclusion, intumescent strips are a vital aspect of fire safety measures. Their diverse types cater to various needs, ensuring comprehensive protection against fire and smoke spread. It is essential to understand the specific requirements and choose the right type to ensure maximum safety in any given situation.
