Providing an essential barrier against the spread of fire and smoke within the cavities of buildings, fire stopping insulation is an indispensable safety component for residential, commercial, and industrial properties. Insulation4Less offers a comprehensive selection of fire stopping insulation solutions, boasting an array to choose from, designed to meet various specific requirements and applications.

Cavity Barriers and Stop Socks

  • Cavity Stop Socks and Party Wall Cavity Stop Socks (Various Colours) Specially designed to inhibit the spread of fire through cavity walls, these products come in a spectrum of colours, including red, light blue, green, black, and more. Regardless of colour, they serve the essential function of providing a robust fire-resistant barrier within wall cavities.
  • Timber Cavity Barriers (TCB) Available in red, yellow, orange, and other variations, TCBs cater specifically to timber frame constructions. These barriers prevent the vertical and horizontal spread of fire within external wall cavities.
  • T-Barriers With options such as T-Barrier Masonry, T-Barrier Timber Frame, and T-Barrier Pitched Roof, these serve to provide compartmentation within varying types of structures and applications.

 

Cavity Closers

  • SuperCLOSE, Contract-Closer, and Various Thermo-Loc Cavity Closers Cavity closers like SuperCLOSE XPS Insulated Cavity Closer and different variations of Contract-Closers and Thermo-Loc Cavity Closers serve to seal cavities while providing thermal insulation and a robust barrier against fire spread in varying fire ratings (e.g., 30-min, 60-min).
  • Smart-Closer Series Including options like Smart-Closer, Smart-Closer Plus, and their single flange variants, this range offers adjustable and efficient thermal and fire performance.
  • Eco-Closer Series Eco-Closer and its variants cater to environmentally conscious projects without compromising on the fire stopping and thermal performance.

 

Cladding and Boards

  • Rockwool Cladding Roll Offering fire-resistant and acoustic insulating properties, the Rockwool Cladding Roll caters to the external facades, providing a layer of protection against external fires.
  • Kemwell Boards Kemwell presents an array of options like Kemwell IsoVent-M, Kemwell FP-900, Kemwell MP-1000, and Kemwell WeatherKem, each one designed for specific applications, such as impact resistance, fire protection, and weather resistance.
  • Quietstone CR Cement Board Providing a strong fire and acoustic barrier, this cement board is suitable for numerous fire-stopping applications.

 

Fire Stop Slabs and Strips

  • Fire Stop Slab Robust and resilient, the Fire Stop Slab is adept at providing a strong fire barrier in various construction contexts, ensuring a potent defence against fire spread.
  • Fire Stop Strip Effective in sealing linear gaps and compartmentalising sections of buildings, the Fire Stop Strip prevents the passage of fire and smoke between different sections of a structure.

 

Choosing the right fire-stopping insulation solution involves considering the specific requirements of your project, such as the type of structure (e.g., timber frame, masonry), fire rating requirements, and any additional performance characteristics like thermal or acoustic insulation. Always ensure to adhere to building regulations and guidelines while selecting and installing fire stopping insulation to guarantee the utmost efficacy and safety.
