Part-E Solutions

Meeting or exceeding Part-E‘s requirements with a suspended timber floor has never been easier than with our range of acoustic deadening floor constructions. We are able to offer Part-E compliance for both between-joist and overlaid systems to suit any final floor finish.

A two-pronged approach

Acoustic performance is normally broken down into two criteria: impact sound and airbourne sound transmission.

Impact sound is most typically experienced as footfall through the ceiling from the floor above and is often the chief cause of noise complaints. Our Part-E constructions serve to attenuate impact sound transmissions by introducing changes in density throughout the construction, i.e. materials of similar densities are separated by resilient layers of lesser density. These layers are installed as floating elements as mechanically fixing from one layer to the next helps impact to sound to cross the layers more easily.

Airbourne sound transmissions could instead be loud, bassy music being played upstairs. Deadening airbourne sound transmissions is as easy as increasing the density of the materials that form the separating floor. Our Ideal ECO heating panels are our densest offering and, in conjunction with either Fermacell boards or our Screed Replacement Tile system, provides hugely impressive acoustic performance.

01
All between joist solutions from JUPITER have to be installed on a stable timber substrate positioned between the joists. In case of our Part-E solution, the ply should be set 21 mm below the top of each joist. The ply should be glued and screwed to the battens.

02
Joists may be levelled beforehand either by installing ply on the side of the joists and then infilling between the two. This procedure also significantly stiffens the joists. Alternatively joists can be levelled by introducing wooden firrings.

03
The 9 mm Redupax wood fibre acoustic strips should be cut to the exact width of each joist.

04
The Redupax strips can either be left floating on each joist or stapled into position. The ply insert should now be 30 mm below the top of the Redupax.
