The Harpun Danish system for installing and levelling decking and joist-laid floors.

The system, comprising feet and levelling wedges with a range of accessories, is a simple, economical, durable and lightweight solution. Indispensable when it is necessary to raise a floor or terrace by between 30 mm and 290 mm.

The basic components of the system are the feet and wedges, which are used to set up the support. This component is often referred to as an adjustable support, terrace support, joist support or levelling foot. Regardless of the name, it is used to raise the joists on which a terrace, wooden floor, sports floor or subfloor is to be laid, to the appropriate level.The system comprises 4 types of feet, 3 types of wedges and 2 types of bases, all of which fit together. This allows them to be combined freely to achieve the required support height.

The main applications of the system are the levelling and installation of:
- floors on joists,

- terraces.

A floor on joists raised on Harpun supports creates space for installations and insulation. The structure is lightweight and durable. The load-bearing capacity of a single support point is 400 kg.

System accessories:

A protective plate that allows the system to be used on surfaces requiring protection against damage, such as roofing felt, construction film and geotextile. Thanks to its specially smoothed edges and the special composition of the mixture, it creates a secure base for the bracket. It increases the contact area with the substrate, which works perfectly on XPS boards.

The rubber pad reinforced with a protective plate has been designed to provide additional noise damping. Its use significantly reduces the transmission of sound through the floor to rooms below. Additionally, it reduces the point load of the bracket.

The soundproofing pad is also used to dampen the floor.

The sports underlay is designed for floors in sports facilities; its special shape gives the floor resilience whilst protecting it and reducing unwanted vibrations.
