In highly insulated houses it is very important to prevent interior air to enter into the fabric of walls and roof. Otherwise condensation can take place within the construction. The moisture mechanics following the laws of physics is not negotiable…
- Checking every corner for leaks
Careful planning and dedication from everybody on the team is a necessity.

Vapourbarrier is installed with care
All done, vapourbarrier ready
Very few people in Sweden has seen a sight like this – Irish carpenters not working! But it happens almost every Sunday (that they do not work work for a little while)……

The inside finishing of a house take some time when everything has to be perfect. This is 7 weeks from start erecting the house. A two-storey version of our well known Hibernia model. Called Draget in two storey versions. With the attic converted we get a total floor-area of 304m2 divided into three apartments.
Fake chimneys contain all ventilation ducts. We reduce heatlosses by only penetrating the roof insulation and seal layers in two positions. Looks better too….
The merchant house from 1860 from seen from Kungsgatan. Scandinavian Homes made a passive renovation of this house two years ago. Green umbra linseed oil paint by Wibo and sidehung windows helps to maintains the character. The windows are equipped with super-glazing, 50mm thick glass-cassettes. All solid wood and side-hung, outwards swing, just like it was in the past. Feels very good for the eye, to touch, and for the wallet when the Swedish winter sets in.

Next door is Culture Cafe Earth if we translate the name of the cafe. Scandinavian Homes Swedish office is located just around the corner.
With a two storey house it is important to have every detail perfect on the roof while the scaffolding is still there. A small platform, some steps and a long roof rail are installed on all Swedish roofs for safety. A roofwindow gives convenient and safe access to the roof in the future.
Another item that we do not need in Ireland is a special rail that prevents massive amounts of snow from falling from the roof. In Sweden we have to expect perhaps 1m thick layer of snow on the roof in the winter. The roofconstruction needs to be designed for this weight as well.
Today we has a meeting discussing the importance of air-tightness with our full team of carpenters. (Good thing that we finally got a larger TV) A good understanding of the technique of taping together the vapourbarrier is important for everybody working on high-performance buildings.
