K103 Kingspan Applications
Kingspan Kooltherm K103 Floorboard is a premium designed insulation for installation under floors. We recommend Kingspan floor insulation to insulate beam and block concrete, and timber floors. It has compressive strength above 120 kPa at 10% compression, meaning it retains its effectiveness even under heavy floors.
75mm Kooltherm K103 Installation
75mm Kingspan Kooltherm K103 Floorboard is intended for installation under concrete floor slabs, screed or timber floors. Installing insulation under floorboards is less complicated than installing insulation in pitched roofs, but it is still important that they are secure and correctly installed.
It is important to check the space under your floorboards for rot and structural issues. The simplest way to install the boards is to place them between the floor joists. We always recommend using equipment to secure the insulation boards, but in most cases you do not have to. Always consult a professional before undertaking insulation projects.
K103 Standards
Kingspan Kooltherm K103 (product code) has a premium performance insulation core. It has many benefits and an indefinite life due to it being resistant to water vapour and air infiltration resistant - but its durability depends on the supporting structure.
K103 is management system certified under quality management systems, occupational health & safety management systems, environmental management systems and energy management systems.
Customer Reviews
The K103 is a premium performance floor insulation and boy does it keep the new extension warm. Installed against block concrete and timber and had no issues going in. Will buy more if I ever build again in my old age.
