Kingspan Cavity Closers

Why choose Kingspan Kooltherm Cavity Closer for your project?
Kingspan Kooltherm Cavity Closer (KKCC) is an ideal choice for construction projects, providing exceptional thermal insulation with a low thermal conductivity of 0.022 W/mK.

Versatile and environmentally friendly, the product suits various window and door frames, including timber, metal or plastic. Its durable design also simplifies construction by eliminating the need for cut bricks and blocks, saving time and money.

KKCC is compatible with various window and door materials, making it suitable for both new build and refurbishment projects. It can be used with uPVC, timber, metal and composite window frames. The product is available in thirteen profile widths ranging from 50-150mm, ensuring a perfect fit for different cavity widths and construction requirements.

A line of compatible accessories, including Jointing Clips, Jointing Strips and Optional Fixing Ties provides flexibility in design options and efficient installation.

The Thermabate Cavity Closer features a core of rigid thermoset urethane (PUR), which is known for its excellent insulating properties. This core effectively reduces thermal bridging by retaining more heat at window and door reveals, thereby minimising the risk of condensation on these typically colder surfaces. Additionally, Thermabate acts as an integral damp proof course (DPC), preventing moisture ingress around openings and reducing the likelihood of mould growth in these areas. Together, these features provide a durable and mould-resistant solution to traditional methods of closing cavities, addressing condensation concerns and enhancing the longevity of building materials.

The main difference between Kingspan Kooltherm Cavity Closer and Kingspan Kooltherm Cavity Closer PLUS lies in the installation and design. The PLUS version consists of pre-formed sections assembled into a frame, reducing both labour and installation time.

KKCC PLUS shares the same profile widths as the standard Cavity Closer and is manufactured off-site to precisely match specified opening sizes. It’s compatible with various window frames, using either an insulated lintel or a KKCC section at the head.

Kingspan is committed to environmental sustainability, particularly evident in their range of cavity closers. As part of their “Planet Passionate” initiative, Kingspan aims to meet sustainability goals by 2030, focusing on using renewable energy, reducing carbon emissions, promoting circularity and managing water resources responsibly. Products like the Kooltherm Cavity Closer are a testament to this commitment.

They are constructed with a uPVC J-section and a high-performance, fibre-free rigid thermoset phenolic insulation core, utilising a blowing agent with zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP). These materials and manufacturing processes are designed to enhance thermal efficiency while aligning with Kingspan’s dedication to reducing environmental impact across their product line.

The Kingspan Kooltherm Cavity Closer itself does not have a specific fire rating. While Kingspan products are designed to meet high standards of safety and performance, including considerations for fire safety in many of their products, this particular cavity closer does not come with an independent fire rating certification.

For applications where enhanced fire performance is necessary, it is important to consult with us directly to discuss solutions or additional measures that can be implemented to meet fire safety requirements.
