Kingspan Insulation

Kingspan is one of the world’s most well-known and trusted manufacturers of insulation boards. They offer floor insulation, cavity wall insulation, wall insulation and roof insulation for residential buildings. Kingspan has a wide range of different boards that they have specially designed so that you can have the best board for the application. Depending on the use of the Kingspan insulation board, it will either be covered with foil, glass tissue, or a bitumen finish.

A popular range from Kingspan is the Kingspan Kooltherm, as it allows the use of a thinner board without interfering with the U-value. It is made from a fibre-free, rigid thermoset phenolic core and will give a higher thermal resistance than standard PIR insulation at 0.018 - 0.023 W/mK. Kooltherm insulation is used on residential buildings, oil rigs, hospitals, industrial buildings, and many other building types due to its great fire resistance.

The K5 range, for example, is covered with tissue-based facing that is bonded to the insulation core, and is designed for external wall applications, as it allows you to render plaster over the material. Kingspan Kooltherm Cavity Closer is a uPVC extrusion with premium performance, fibre-free, rigid thermoset phenolic core that provides a simple and efficient method of closing cavities around openings in masonry cavity walls.

If you are more interested in reducing the amount of noise that travels through the building, you should view our acoustic insulation. For more information on our Kingspan's products or the right choice for your project, get in touch with our team on 020 3582 6399 or through our Live Chat .

Kingspan Insulation, a prominent name in the insulation industry, offers a robust selection of insulation products adept in providing exceptional thermal performance for various applications. With a dedication to sustainability and energy efficiency, Kingspan products are engineered for durability, ease of installation, and optimal thermal regulation across an array of structural systems and builds.

Floor Insulation Boards

Specific products like Kingspan Thermafloor TF70 Floor Board and Kingspan Kooltherm K103 Floorboard are designed to provide high-performance insulation for ground floors. They cater to both solid concrete and suspended timber floors, ensuring minimal heat loss and providing a stable temperature within the interior space.

Roof Insulation Solutions

Kingspan Thermaroof (TR26 & TR27) and Kingspan Thermapitch TP10 are integral for insulating flat and pitched roofs, respectively, ensuring minimise energy loss through the top of your buildings. Various alternatives such as the Kooltherm K107 and K7 Pitched Roof Boards provide additional options with their own unique thermal conductivities and application suitability.

Wall Insulation Products

Wall insulation solutions like Kingspan Thermawall (TW55 & TW50) and Kingspan Kooltherm K112 Framing Board are fabricated for steel/timber framing and cavity walls, respectively, safeguarding the internal environment against external temperature fluctuations.

Waterproofing & Membranes

Products like Kingspan Aquazone Infiltration and Nilvent Breathable Membrane are crafted to offer excellent water infiltration and breathable membrane solutions, ensuring the longevity of your structures and maintaining optimal indoor environments.

Selecting The Right Product

Selecting the right insulation product is paramount in achieving the desired thermal efficiency, durability, and comfort. While Kingspan Therma range might be suited to more conventional applications with its straightforward installation and reliable performance, the Kooltherm range might be favoured for scenarios demanding higher thermal performance in slimmer profiles.

For specific technical requirements or unconventional structures, specialty products like the OPTIM-R series or Kingspan Thermataper provide tailored solutions that address unique insulative challenges.

In application spaces where sustainability and environmental impact are of high importance, the Greenguard series offers insulation options that are not only effective but also mindful of their ecological footprint.
