Frequntly Asked Questions
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.
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.
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.
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.
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.
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.
