Cavity Closers

Cavity closers are necessary for preventing heat loss and water penetration in buildings with cavity walls. They are especially important around window and door openings. Without cavity closers, there is a risk of dampness and mold growth, as well as higher energy bills due to heat loss.

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.

Yes, you can plaster over plastic cavity closers. However, it is important to ensure that the surface is clean and free of any debris before applying the plaster. It is also recommended to use a bonding agent to help the plaster adhere to the plastic surface.

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.
