  • What does a cavity closer do?
    A cavity closer is a material used to fill the gap between a window or door frame and the surrounding wall. It helps to prevent heat loss and drafts, as well as keep out moisture and pests. Without a cavity closer, your home could be less energy-efficient and more prone to damage.
  • Can you plaster over plastic cavity closers?

  • What are the building regulations for cavity walls?
    Building regulations for cavity walls require that the cavity is at least 50mm wide and that it is properly ventilated to prevent dampness. The insulation used in the cavity must also meet certain thermal performance standards. Additionally, any openings in the cavity, such as for pipes or cables, must be properly sealed to prevent air leakage. It is important to consult with a qualified professional to ensure that your cavity wall meets all necessary building regulations.
