FAQ

All your building acoustics questions answered here. … Listed below are answers to some of the questions we are asked regularly. .

Frequntly Asked Questions

1. Please advise suitable flanking strip to specify with 28mm Cellecta ScreedBoard.

This depends on the floor finish you are looking at and whether you intend to install the ScreedBoard prior to drylining. It is important that all aspects of the wall treatment are isolated from the floor. For ease of installation, Cellecta manufacture various flanking strip sizes. Should you only need to isolate the skirting board then FS30 is the most suitable. Should you need to isolate the plasterboard and skirting then FS50 will be more suitable. Finally for areas where vinyl is being installed the specially designed FS15 can be utilised.

2. Installing ScreedBoard 20, can you tile straight onto it?

The ScreedBoard 20 as an exceptional level of tolerance and therefore can take a multitude of floor finishes. You will need to prime and seal the board with our MP60 before installing the tile adhesive.

3. I require a very thin system to achieve underfloor heating over the top of an existing screed floor that will allow me to lay timber flooring and tiles over the top.

Cellecta’s XFLO Micro TB utilises our ultra-strength, 500kPa insulation routed to suit your underfloor heating pipe. The board also has tile membrane to ensure an exceptional bond for tiles or wooden flooring. Starting at 15mm the board offers a very minimal increase in the overall floor height whilst having very good resistance to downward heat loss.

4. Grade II* Listed building. I need to retain the floorboards. Do you have a floating system I can lay directly on the floorboards which won't damage the floorboards?

DECKfon Ultramat is a high density composite mat, that improves both airborne and impact performance of a floor where it is not possible to upgrade the ceiling. This is a floating layer that does not need to be fixed to the timber floors therefore negating the risk of damaging your existing floorboards.

5. New build house - Could you tell me if it is acceptable to put chipboard or OCB sheet flooring directly onto the insulation blocks instead of a screed?

Due to the natural expansion of chipboards we recommend that the insulation and chipboard are bonded. If installed in separate layers, the movement of the chipboard can create squeaking. We would always advise the use of HEXATHERM XCHIP, manufactured utilising our outstanding XPS insulation bonded to chipboard, which will alleviate the risk of friction noise.

6. We need to specify an acoustic underlay between the screed and the concrete plank. We would like to know whether the YELOfon HD10+ would require any overlaps when jointing two YELOfon sheets or just the J-strip to be used there?

If overlaying with an underfloor heating system or using a 40mm anhydrite screed, it is acceptable to butt joint the HD10+ before taping this joint with J-Strip. Care must be taken to not leave any gaps that screed can migrate through and it is good practice to install a 500 gauge DPM in this instance. In all other applications you will need to overlap the YELOfon HD10+ by 150mm following the markings on conveniently printed on the rolls for ease of installation.
