What is Kingspan Insulated Plasterboard?
Kingspan insulated plasterboard offers an all-in-one solution to people looking to thermally protect and dryline their home.
Kingspan insulated plasterboards are comprised of a fibre-free rigid thermoset phenolic core with a 12.5mm plasterboard bonded to its front surface and a low emissivity composite foil based facing on its reverse.
These 2-in-1 boards (often referred to as thermal laminates) are used primarily for internal wall insulation; on masonry walls and between timber framing.
What's more, the boards are manufactured with a blowing agent that has zero ODP (zero ozone depletion potential) and low GWP (low global warming potential), making them the go-to choice for people who care about their carbon footprint.
Kingspan Kooltherm K118 Insulated Plasterboard Benefits
- Reduced Installation Time – Kingspan Kooltherm K118 is an all-in-one product comprised of both insulation and plasterboard. It is often cheaper and quicker to buy an all-in-one product.
- Precise application – Kooltherm K118 boards are 2400mm by 1200mm. These are standard dimensions that will suit most insulation needs. Drylining is in-built into the board, which makes for more precise applications. When you buy Kingspan K118 boards, you can rest assured that the pieces of the product have been bonded together in accordance with strict industry guidelines.
- Thermal performance – K118 insulation boards have a phenolic core. Phenolic has a thermal conductivity of 0.018 W/mK, which is the best thermal performance of any insulation in the UK.
- Moisture resistant – These boards have a reverse composite foil facing on one side. This facing delivers effective vapour control. It is important to remember that the boards as a whole cannot handle large downpours. You can improve the vapour-resistant properties of Kingspan plasterboards by applying two coats of Gyproc Drywall Sealer.

Frequently Asked Kingspan Insulated Plasterboard Questions
Are Kingspan Insulated Plasterboards Flammable?
One of the most common questions that customers ask us is whether or not Kingspan K118 insulated plasterboards are flammable. The Euroclass scale measures the flammability of insulation materials. This system, which has been adopted by lots of countries in the European Union, rates insulation products from A1 (non-combustible) to F (very combustible).
The rigid plasterboard has a Euroclass rating of A2, meaning it has a limited contribution to fire. Overall, Kingspan Kooltherm K118 Insulated plasterboard has a Euroclass rating of B. They are classed as a combustible material but have limited contribution to fire.
Which Kingspan Insulated Plasterboard Thickness Should I Choose?
There are lots of Kingspan insulated plasterboard thicknesses to choose from. We stock Kingspan Kooltherm K118 boards that range from 32.5mm to 72.5mm. The board that you should choose depends on the constraints of your project.
You might need to choose a board that is thin enough to fit alongside a build-up of other materials. Other people just need the board itself to fulfil their project requirements. Always consult with a professional if you are unsure.
How to Install Kingspan Insulated Plasterboard?
Kingspan insulated plasterboard can be mechanically fixed or installed via the dot and dab technique. Mechanical fixings are one of the most popular installation options because they hold the board firmly in place.
The dot and dab technique is a variation of the traditional wet plaster method. It involves pasting adhesive to the wall in dots and dabs. Then, you can simply place the plasterboard on the wall. This method is far quicker than plastering an entire wall and saves money in the process. For more information on dot and dab, check out our 'What Is Dot and Dab' post.
