General application PIR insulation (also known as general-purpose PIR boards) are designed for application on floors, walls, and roofs, allowing for a wide range of thermal insulation solutions. These boards work perfectly for pitched roofs, concrete slab ground floors, and outer wall linings and sheathings. General-purpose PIR insulation is perfect when you need to optimize space during construction, and they lower heating and cooling costs.
They are flexible yet sturdy, lasting for many years with minimal maintenance. General application PIR boards are also the perfect green insulation option, as they contribute zero ODP (ozone depletion potential). We have a wide selection of General-purpose insulation boards available from leading brands such as Kingspan, Celotex, Ecotherm, IKO, Xtratherm, and Recticel.
There is also PIR insulation for more specific usage. For example, when you need insulation tailored specifically for a cavity wall or flat roof and floor, you can get a more specialized insulation board for that. We have insulation boards available for any project that you are working on.
If your job calls for something more intricate than your typical general-purpose insulation board for floors, walls, and roofs, browse our selection of PIR boards for specific usage. Our team is focused on helping you find exactly what you need.
There are insulation types perfect for internal partition walls, party walls, and external walls. There are specific usage boards for timber frame walls, steel frame walls, solid walls, cavity walls, timber and metal stud walls, separating walls, and more.
The General Purpose (GP) PIR insulation board of Recticel, Ecotherm, Celotex, IKO and Xtratherm is lightweight, easy to cut, handle and install. Whether it’s a roof, wall or floor, a General Purpose PIR insulation board is the ideal solution amongst contractors and installers. The General Purpose PIR foil board insulation offers a Lambda value of 0.022 Watts per mK.

There are few wall insulation types such as cavity wall insulation, external solid wall insulation and internal solid wall insulation. Modern houses are equipped with cavity wall insulation. An overview of these types and their benefits are shown below.
The most commonly used insulation method is cavity wall insulation. The cavity is the space between the external and internal walls.. Cavity wall insulation is the process of filling the cavity with insulation by using materials such as Polyisocyanurate (PIR), Glass wool, or EPS. Cavity wall insulation also prevents moisture from entering the home. Modern houses are built with insulation boards (insulation panels) from leading manufacturers such as Kingspan, Celotex, Xtratherm, Ecotherm, Recticel, and IKO. If an existing house with a cavity wall is not insulated, using a spray foam insulation is another option.
External wall insulation is not the cheapest option. However, if there is no cavity between the internal and external walls, it is recommended to use external wall insulation. The advantages of having external wall insulation include having no limitation on insulation thickness, not losing interior space, and getting a brand new exterior wall. The flip side of this method is the additional cost that is involved in covering the insulation board or any other insulation material outside.
Placing insulation on an internal wall has few disadvantages including the loss of interior space. Insulating external walls from inside of the house can be done in three ways:
Placing a wooden or metal grid against the supporting wall and filling it with insulation.
Wall insulation is the process of using insulation material on a solid or cavity wall to reduce heat loss through the wall. Having wall insulation prevents heat loss from the wall during the cold season, but it also reduces the strain on air conditioning systems during the summer. One of the main benefits is the improvement of thermal comfort, as well as the reduction of energy consumption which will lead to lower energy bills. On top of that, it has a huge impact on your CO2 emissions.
The main purpose of using insulation is to reduce the transfer of heat via walls, roofs, or floors. How well an insulation material resists heat flow is measured by its Resistance value, also called the R-value. The insulating capability (how the insulation material resists the heat flow) depends on the insulation material type and the thickness of the insulation.
✓ Reduction of heat loss:wall insulation keeps heat inside during the winter and outside during the summer.
✓ Reduction in energy bills: less energy required for heating and cooling the home.
✓ Helps in mould prevention: good quality insulation reduces the risk of moisture issues and the growth of mould.
✓ Reduction of Carbon Footprint: It has a huge impact on the reduction of your carbon footprint. Installing 4 million homes with insulation is equivalent to the carbon dioxide reduction as planting 667 million acres of trees.
There are three types of wall insulation: cavity wall insulation, external solid wall insulation and internal solid wall insulation. Modern houses are equipped with cavity wall insulation. An overview of these types and their benefits are shown below.
