Slide Black System

Plasterboard ceiling with wooden substructure in vaulted roofs, one-side connection

Recommended type of grid: connection type 64

Description

The aquatherm black system grids for heating and cooling are clamped between the wooden furring strips of the substructure of the vaulted roof of a conventional gypsum board. Then the ceiling is covered with gypsum plaster boards, which may have different thermal conductivities.

Installation

1. Substructure
The joist and wooden furring strips are fixed and arranged, subject to manufacturer´s instructions.

2. Installation of the grids
The axis distance, between 300 and 500 mm, of the support construction depends on the applied gypsum board. The connection pipe of the heating and cooling circuits from the manifold or the main supply is fixed in the cavity at the ceiling and is directed in the room. The grids, object-related and made to measure, are hung between the furring strips according to the layout drawing. Therefore the fixing rail for dry construction is pushed on both sides of the fixing rail at the grid and fixed with the integrated cable tie. Now the fixing rail for dry construction can be screwed sidewise in the support pole. If this is not possible, the grids can be fixed at the joist with screws, which are screwed through the fixing rail at the grid.

3. Connection of the grids
For the horizontal arrangement of aquatherm black system grids the flow can be connected optionally left or right. The grids of this system have a one-sided socket connection with a forced flow. The grids can be connected one-sided and a constant flow is assured.
After hanging the grids in the substructure they are interconnected to ­heating respectively cooling areas according to the layout drawing. Therefore the aquatherm black system corrugated pipe from the coil is used, which is separable each 25 cm and can be cut to the required length. The corrugated pipe is welded with an elbow directly at the grid by heating element socket welding, respectively it is directed behind or through the wooden furring strips and connected with the next grid.

The maximum area per heating circuit is 15 m².
The maximum area per cooling circuit – see page 70.
The heating and cooling circuits are connected to the manifold
or the main supply with aquatherm black system PP grid pipe 16×2 mm or alternative connection systems (e.g. aquatherm grey pipe).

4. Installation at the gypsum plasterboard
Note even here that the grid hangs some millimeter lower than the support pole. Now the grids are cased together and connected to the connection pipe. If now the gypsum boards are screwed at the support construction subject to manufacturer´s instructions, they will press the lightly sagging grids upwards. As the grid cannot be pushed upwards due to the fixing rail for dry construction respectively due to the insulation in the piched roof, there is a contact between the gypsum board and the grid. Note that the grids are filled with water and are pressurized during the planking
