Jumpax® Family: a subfloor for every situation

Jumpax® is the original underlay developed by Unifloor itself. The Jumpax® Family guarantees a high-quality, reliable solution for every situation. There is a suitable Jumpax® underlay for every combination of subfloor and top floor.

The first subfloor that we developed at Unifloor was Jumpax® Classic. Initially it was called Jumpax® Original, but all other members of the Jumpax® family are original and were developed by us as well. For the original, with all the knowledge and expertise that went into it, you should still go to Unifloor.

All Jumpax variants are equipped with a bottom and top sheet, both of which have an interactive adhesive.

Jumpax® Classic
This underlay consists of two layers of MDF (3+4 mm) with 3 mm EPS underneath. The EPS improves the impact sound insulation and levels out unevennesses up to 3 mm.


Jumpax® HD
For heavier loads such as offices and gyms, we have developed subfloors with 2 x 4 mm MDF. The Jumpax® Heavy Duty (HD) has an underlayer of 2 mm PE foam that insulates impact sound and levels out unevennesses of 2 mm.

Jumpax® Nature
Especially for wooden subfloors, there is also a variant with 2x 4mm MDF with a 6.5mm softboard. This underlay has great levelling properties and is made from natural materials, hence the name Nature.
