Instruction for Use

Preliminary operations

Before starting the works, the materials necessary for the execution of the work must be gathered, which are:

Stakeout equipment
The installations must be finished before laying the CONFORDAN BT sheet.
Ground unevenness of more than 3 mm in 1 m must be levelled beforehand with levelling paste.

Fixing equipment
Aluminium ADHESIVE TAPE should be used to fasten the sheet to each other and to any point on site such as slabs, pillars, walls or any other structural element that acts as an electrical earthing system.

Laying of CONFORDAN BT

Unroll the CONFORDAN BT in the longitudinal direction of the boards, cutting the necessary size with a cutter.
It is advisable to overlap and seal with aluminium adhesive tape to give continuity to the insulation and prevent damp from penetrating.
Install the floating floor according to the manufacturer’s instructions.

Indications and Important Recommendations

The floating mortar must be strong enough to prevent cracking. (See SPD No. 1.3).
The skirting boards should be at least 15 mm thick to cover the expansion gap and to avoid creating an acoustic bridge, they should be left with a small gap that can be created by means of a silicone bead.
The planks must remain for at least 48 hours acclimatising to the room in which they are to be installed at an ambient temperature of at least 17°C, relative dampness not exceeding 70%.
It will be taken into account that this product is part of a Sound Insulation system, so the Danosa Constructive Solutions Catalogue, Sound Insulation Commissioning must be taken into account. "Details of Singular Points" (SPD), as well as the rest of the Danosa documentation.
