Cavity Closer System
A Smart Solution for Builders, Contractors, and Self-Builders
The Cavalok Cavity Closer
The Cavalok Cavity Closer isn't just a window and door former; it's your go-to horizontal and vertical damp-proof course too. It's designed with small builders, contractors, and self-builders in mind, offering both standard and check reveal options for seamless integration into new build timber frame, brick, or block constructions. With every installation, you can rest assured of a perfect fit and compliance with building regulations.
This versatile system accommodates cavity sizes ranging from 75mm to 150mm (130mm for check reveal) and readily accepts 70mm PVC-U systems. The installation process involves placing the former in situ, allowing brick and blockwork to be built around it. This means you can fit windows and doors at a later stage in the construction process, reducing the risk of damage.
What's more, it's fully in line with NHBC standards and delivers the thermal and energy efficiency performance required to meet the Accredited Construction Details of Part L of the Building Regulations. It even incorporates a head vent for overhead ventilation, as specified in Approved Document F.
With an impressive 98% recycled content in the cavity closer component, it's an eco-conscious choice. Plus, it's compatible with both PVC-U and timber window or door systems, offering you flexibility and convenience on the job. Choose the Cavalok cavity Closer System to ensure compliance with building regulations without compromise.
