The stable underfloor system for underfloor heating
Heat-Pak® Plus is a floating underlayment system that is specially designed for installation over various types of underfloor heating systems. Heat-Pak® Plus provides a perfectly smooth and seamless underlay, which virtually excludes any unevenness in the floor. This system is therefore extremely suitable for directly gluing resilient floor coverings such as LVT, linoleum and rubber.
Heat-Pak® Plus has a very low thermal resistance, so the heat of the heating system is transferred smoothly and efficiently.
Heat-Pak® Plus is extremely suitable for use in combination
with electric underfloor heating and hot water underfloor heating systems.
Heat-Pak® Plus is the solution to obtain a very stable subfloor quickly and easily, making cumbersome and time-consuming liquid levelling compounds unnecessary.
Heat-Pak® Plus consists of a 10 mm gypsum base plate and a 4 mm MDF top plate. Both plates are provided with an interactive adhesive that bonds the plates together to form one stable system. Once installed, Heat-Pak® Plus not only protects your underfloor heating system, but also your floor covering.
