What is Kingspan Insulated Plasterboard?

Kingspan insulated plasterboard offers an all-in-one solution to people who need both thermal protection and drylining. Insulated plasterboards are comprised of a sheet of plasterboard that is bonded to one side of a sheet of insulation. These 2-in-1 boards are sometimes called thermal laminates.

Insulated plasterboards can be installed on internal walls and in loft spaces. Most people use them to improve the thermal performance of the walls in their homes. Homeowners lose around 35% of the heat in their homes through the walls. K118 Kingspan plasterboards are designed for installation on masonry walls and between timber frames.

Kingspan Kooltherm K118 Insulated Plasterboard

Insulated plasterboards contain all kinds of different insulation materials. Most manufacturers use PIR (polyisocyanurate) because it has low thermal conductivity, low global warming potential (GWP), and zero ozone depletion potential (ODP). Kingspan Kooltherm K118 Insulated Plasterboard uses phenolic insulation, which is even more thermally efficient than PIR insulation. Kingspan are not only the leading manufacturer of phenolic insulation, they are also the only manufacturer of phenolic insulation in the UK. Phenolic insulation is more expensive than PIR insulation, but with thermal conductivities as low as 0.018 W/mK, it is the best option for homeowners who want to reduce their energy bills.

Kingspan Kooltherm K118 insulated plasterboard is comprised of a phenolic core that is sandwiched between a reverse composite foil facing on one side and a plasterboard on the other side. The reverse composite foil facing promotes vapour control, and the rigid drylining plasterboard provides a basis for easy installation.

Kingspan Kooltherm K118 Insulated Plasterboard is 2400mm x 1200mm and available in a range of thicknesses from 32.5mm to 72.5mm. You can install them with either mechanical fixings or the dab and dot method.

Phenolic Insulation

Kingspan Kooltherm K118 Insulated Plasterboard has rigid thermoset insulation materials and phenolic foam core. This material is a premium performance insulation made from phenolic resin, a blowing agent, and an acid catalyst. To make the plasterboard, Kingspan applies a layer of wet phenolic foam directly to a reverse composite foil facing. As phenolic dries it becomes tacky and adheres to the bottom board. Kingspan places a plasterboard facing above the foam at the desired thickness. Phenolic foam expands and adheres to the plasterboard. The board is then cooked under extreme heat and cured for hours.

Phenolic insulation is the number one choice for people who want to improve the thermal envelope of their homes. It has a thermal conductivity value of 0.018 W/mK. It is significantly more effective than PIR insulation, which has a thermal conductivity value of 0.022 W/mK.

Frequently Asked Kingspan K118 Insulated Plasterboard Questions

Benefits of Kingspan Kooltherm K118 Insulated Plasterboard

There are lots of advantages to buying Kingspan Kooltherm K118 insulated plasterboard:

●     Installation – Reduced installation time. It is an all-in-one product that is comprised of both insulation and plasterboard. You do not need to buy insulation and drylining separately when you choose Kingspan Kooltherm K118. 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.  

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).

Kingspan Kooltherm K118 Insulated Plasterboard is comprised of three main elements. It contains a phenolic foam core with plasterboard on one side and a composite foil facing on the other. 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. Kingspan K118 boards are 2-in-1 products that combine insulation with drylining, which means that they can be installed on masonry walls or between timber frames on their own.

How to Install Kingspan Insulated Plasterboard?

You can install Kingspan insulated plasterboard can be mechanically fixed or even 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.
