Welcome to the Cavity Closers category at Build4Less. Our selection is tailored to meet a variety of construction and insulation needs, ensuring the right fit for any project.

Types of Cavity Closers

Our range includes several types of cavity closers, each designed for specific applications:

  1. Fire-Rated Cavity Closers: Ideal for projects requiring enhanced fire safety, these products, like the Thermo-Loc FRSTOP, offer up to 60 minutes of fire resistance. They are available in different sizes to suit various wall thicknesses.
  2. Check Reveal Cavity Closers: These closers, including the Thermo-Loc Platinum Plus Check Reveal Multi Cavity Closer, provide not only thermal insulation but also aid in window and door installation by creating a straight and clean finish.
  3. Multi Cavity Closers: Suitable for larger scale projects, our multi cavity closers, such as the Thermo-Loc Platinum Plus Multi Cavity Closer, offer a practical solution for insulating multiple cavities in a single installation.
  4. Insulated Cavity Closers: Products like the SuperCLOSE XPS Insulated Cavity Closer and Kingspan Kooltherm Cavity Closers are designed for superior thermal performance, reducing heat loss and improving energy efficiency.

  5. Specialised Cavity Closers: We also offer specific products like the Rockfibre Insulated DPC and Eco-Closer Plus for unique requirements, including environmental sustainability and damp proof coursing.

     

Selecting the Right Cavity Closer

When choosing a cavity closer, consider the following:

  • Fire Safety Requirements: For buildings where fire safety is paramount, opt for fire-rated cavity closers.
  • Thermal Insulation Needs: If energy efficiency is a priority, insulated cavity closers are the best choice.
  • Installation Type: Check reveal cavity closers are ideal for precise installations around doors and windows.

  • Project Scale: For larger projects, multi cavity closers provide an efficient solution.

     

Remember, the right cavity closer not only enhances the structural integrity of your build but also contributes to energy efficiency and safety compliance.
