| A. | In an installation of this kind we must be careful because the flooring has to stand especial circumstances.
The places of this kind are normally extremely damp and are exposed to abrupt temperature changes. It is quite usual that the sunlight acts directly on the laminate through the window and that causes that the flooring surface gets a quite high temperature. If we add to this that the ground is normally quite cold, the flooring has to stand abrupt temperature changes.
Those days when the sun shines, it may be very hot during the day and then very quickly the temperature decrease very sharply at night. This reduction and expansion may damage the profiles and make the planks separate in their short sides.
Because the laminate flooring is in direct contact with the ground, it may be a big difference in the temperature of both sides of the board, the upper side with higher temperature than the lower side in direct contact with the ground.
If laminate flooring has to be installed in any of the abovementioned places, maybe the conditions of the installation can be improved if we place on the sub-flooring:
- Firstly, a 0,2 mm polythene steam barrier.
- Over this barrier, a thick heat insulator layer > 6 mm (cork, low density board, polypropene, etc.)
- We recommend that the product acclimatizes in the place where it is going to be installed, prior to its installation.
- During installation, we will apply an adhesive (Glue D3) in the transverse joints and this way we will strengthen the joint of the short sides of the boards, that will be placed separated from the others (adjoining) always 1/3. |
