50mm Kingspan Kooltherm K108 Cavity Insulation Board 1200mm x 450mm (5.4m2/Pack)

Did you know that cavity wall insulation is one of the cheapest energy saving measures you can install? 50mm Kingspan Kooltherm K108 Cavity Insulation is a premium performance partial fill cavity insulation solution, designed for use in external cavity walls. 

Providing a level of performance that is unrivalled in the world of rigid thermoset insulation, 50mm K108 Cavity boards boast an impressive lambda value of just 0.018 W/mK; making them the most thermally efficient cavity insulation solution on the market. 

These 50mm rigid Kooltherm K108 thermoset cavity insulation boards are comprised of a fibre free rigid thermoset phenolic core flanked by a layer of low emissivity composite foil on either side. 

As well as being thermally efficient, Kooltherm K108 cavity board is also manufactured in a super environmentally friendly process, using a blowing agent with zero Ozone Depletion Potential and a low Global Warming Potential; one less worry for you and the environment.

K108 forms part of the Kooltherm K100 range, which boasts an excellent thermal conductivity of just 0.018 W/m·K across all thicknesses. Kooltherm K108 insulation is a high performance phenolic insulation board specially designed for installation in partial fill cavity wall applications.

The boards offer premium thermal performance whilst maintaining a clear cavity and resisting moisture. Each board features a fibre-free rigid phenolic core that is sandwiched between low emissivity foil facings. These low emissivity foil facings significantly increase the thermal resistance of the cavity and lend themselves to the board's thermal conductivity of just 0.018 W/mK. 

Not only that, but 50mm Kingspan is completely unaffected by air infiltration, thus improving the thermal performance of the entire construction. We cannot recommend these boards enough for people who are looking to receive the best thermal protection.

Their environmental credentials are just as impressive - the boards are manufactured with a specially designed blowing agent that has low global warming potential and zero ozone depletion potential (ODP), making them a green insulation choice; meaning you can comfortably up the heat in your home with zero guilt.

50mm Kingspan K108 Board Applications

Homeowners lose around 35% of the heat in their homes through their walls. If you're thinking about insulating your home, partial fill cavity wall insulation should be your first port of call. K108 Kingspan boards are top of the range when it comes to partial fill cavity wall insulation. In fact, Kingspan is the only manufacturer of insulation with a fibre free rigid thermoset phenolic foam insulation in the UK.

Kingspan Kooltherm K108 insulation is available in 50mm, 60mm, and 100mm thicknesses. It is manufactured in accordance with ISO 9001: 2015 (Quality Management Systems), BS OHSAS 18001: 2007 (Occupational Health and Safety Management Systems), BS EN ISO 50001: 2011 (Energy Management Systems), and ISO 14001: 2015 (Environmental Management Systems). The 50mm K108 has a pack coverage of 2.7m2, with 5 boards of 1200mm x 475mm per pack.

Kooltherm K108 Cavity Board Handling & Installation

Kingspan K108 boards are non-deleterious, rigid, and lightweight, making them super easy to install. One of the biggest benefits of these boards is that they are manufactured at 1200mm x 475mm to suit standard wall tie spacings.

K108 Kingspan boards are partial-fill, which means that they are intended to only partially fill the cavity, leaving a residual air gap. Simply use wall ties to hold them in place. We recommend installing wall ties in the inner leaf of brick walls at 475mm height.

Cavity wall insulation boards are used to insulate external cavities where heat retention is the main priority. 

50mm Kingspan K108 Insulation Phenolic Core

Kingspan K108 boards are the most popular choices for homeowners who want to improve the thermal envelope of their homes through partially filled cavity walls. As a premium performance insulation board, Phenolic foam is a touch more costly than other kinds of insulation but as its performance is unrivalled in the world of rigid thermoset insulation materials, we believe it to be worth every penny. 

Kingspan K108 boards have been specifically designed to limit thermal bridging and uncontrolled air leakage via junctions in cavity wall constructions, which is clearly demonstrable in its thermal conductivity value of 0.018 W/mK. However, the benefits of phenolic K108 Kingspan boards don't just stop there. It is also a non-deleterious material, which means that you do not have to worry about health hazards during the installation process. 

Thanks to its closed-cell structure the board is also rigid and durable whilst still maintaining a light and manageable weight.
