How do I use Subfloor?


Look at our assembly video and step by step guide:

How high raise Subfloor be raised?


Building heights are a minimum of 31 mm using just the screw and a maximum of 348 mm using the acoustic screw foot. Look at our building heights table to look at all the variations!

How heavy loads can Subfloor take?


The load document will be here soon! However there is never a point load on a single screw as the force is spread out across the floor.

Can Subfloor be used with insulation?


Yes, very easily. Insulation bearers hang onto the Subfloor joists and are available at varying heights. See our products page for all the variations!

Does Subfloor come with Chipboard/top layer?


No, as anything can be placed on top.

How fast is Subfloor to assemble?


Fast. This is how you assemble Subfloor.

The typical speed of assembly with 1 person is:
Smaller rooms, Subfloor system and floor on top = 5 - 6 m2 per hour per person
Smaller rooms, Subfloor System = 6 - 7 m2 per hour per person
Larger rooms, Subfloor System = 10 - 12 m2 per hour per person
Typically an assembly team of two people is recommended. Therefore these values double, for example: Smaller room, Subfloor System = 12 - 14 m2 an hour.

What is Subfloor acoustic?


An acoustic foot is attached to the screw which reduces vibrations and noise by up to 28 dB.

How does the acoustic foot work?


Specially formed rubber within the foot absorbs vibrations, damping their amplitude and therefore the noise levels.

Does a load affect the acoustic damping?


No. The rubber in the foot is formed so that it has different stages of compression to cope with any load.

How can I decrease noise further?


To decrease impact vibration more a gypsum board can be used. Different methods are used depending on the environment. Get in contact for specific enquiries!

Airborne noise can be reduced by using insulation that is attached using our insulation bearers onto Subfloor.
