Installing the Vallox BlueSky system into 1980s house alongside renovation

Talo terveeksi is a video series created by the YouTube channel Timpurilta Talo. The series is about renovating a 1983 house in Järvenpää, Finland, to meet modern requirements. Indoor air problems are addressed at the same time. The renovation project began by dismantling the house’s interior, after which the house has been practically rebuilt.

Episode 16, uploaded in January 2024, featured the installation of ventilation. Vallox BlueSky was selected as the house’s ventilation solution. It is a great choice due to its low space requirements and the ability to be installed into heated areas without extra insulation.

The episode opens with carpenter Mikko Merelä being astonished by the size of the pallet delivered on site: “I have to admit that I’m more than a little surprised. I knew these were smaller tubes, but I’m amazed by how little space they all need.”

The day’s installation project begins by installing small supporting pieces to the ceiling. Vallox BlueSky tubes can be installed between them by using various fasteners and bands.

“I’d say that for renovations, this is quite an unbeatable system”, Merelä says while working.

When renovating a house, the goal is to keep the room height as high as possible. Vallox BlueSky tubes have an exterior diameter of only 75 mm, making them a great fit for the site.

“What’s really cool about this is that now that we have these here against the ceiling, we won’t have to lower the ceiling from the normal height much.”

If ventilation tubes can be fully installed into heated spaces, i.e., inside the vapour barrier, such as a dropped ceiling, the tubes do not require insulation and the vapour barrier does not have to be perforated unnecessarily.

“What’s best about this is that now that were able to place all of the tubes inside dropped ceilings, there was no need to insulate them. Everything was installed into heated spaces. Only the outside and exhaust air tubes needed to be insulated.”

The renovators also praised the ease of installation:

“Installing these tubes was really simple and fun. It was a quick job.”

In the episode below, Mikko Merelä and his team showcase the installation of Vallox BlueSky tubes and other system components in their professional but casual style. The video is only in Finnish.

Later in the construction project, the crew also installed a Vallox ventilation unit.
