Wall ties are typically installed between a fixed wall and a plasterboard wall. The plasterboard wall is installed resiliently, and the plasterboard wall can be constructed using steel profiles or structural laminated veneer lumber. Another option is to install both walls resiliently. Typical applications consist of music rooms, recording studios, cinemas, residential and office buildings, nightclubs, concert venues, industrial developments, and laboratories.

Acoustic wall ties follow EN 14195 standard requirements. Declaration of Performance and CE-marking have been completed for the acoustic wall ties.

Figure 1 below shows Acoustic Wall Tie 128NN design.

Outdoor unit weight is concentrated on the compressor side where pipe connections locate. Therefore, two sets of springs are installed on the compressor side and one set on the other. Figure 2 below shows the spring isolators at both sides of the outdoor unit.

During the cold weather the outdoor unit will defrost ice, and this causes water to drain below the outdoor unit. It is recommended not to let the water to drain near the house. Therefore, it is good to fit a plastic tub below the outdoor unit, which can be emptied away from the house. Figure 3 below shows the final installation for the outdoor unit with a 90 liter plastic tub.

One additional recommendation is to install the piping flexibly and this is achieved by using 360° loop at the outdoor unit piping. Figure 4 below shows the piping loop. With this arrangement the vibration isolation performance can be guaranteed as the piping also allows needed flexibility for the springs.

Air conditioning units are not always an attractive addition to a building and many owners want to cover them. Here shown wooden support bracket functions perfectly as the support frame for a wooden cover. Figure 5 below shows one possible wooden cover design, which was made for an outdoor unit with InfiniSpring®-wooden support bracket.

Air conditioner outdoor unit noise can easily disturb inside the house, if noise isolation is not done properly. To avoid the disturbing structure borne noise, it is required that the outdoor unit is installed resiliently on soft springs/mounts. We can provide the springs and also instructions for building the heat air pump wooden support brackets. Actually any type of wooden support bracket can be made easily and for any need. Please do not hesitate to contact us, if you have any comments or questions or have interest to know more.
