Raw linseedoil, Jupex 45, wooden tar, Jupex varnish and pigment for low energy houses and passive houses

Raw linseedoil, Jupex 45, wooden tar, Jupex varnish and pigment.

-External wood: Pressure-wash, let it dry completely, apply one of the oils with brown pigment to saturation-point. Advice: Mix in some wooden tar in the oil to make it smell like a real Viking longboat, this prevents black spots too. Not to be confused with tar from stone-coal, the wooden tar is light and runny, it is made from sap-rich pine.

-Windows: Sand with 220 sandpaper, apply pigmented oil to
saturation + apply pigmented Jupex varnish. It is the exposure to sun that cause the aging of paint and varnish on the south side.

-External doors: Sand it even with 220 paper. Apply oil to saturation point, this means perhaps 5 times, add pigment to oil so it becomes almost like a paint, apply thin and wipe off until surface is perfect smooth and all small cracks are filled (No slobbering with too think layers!!)
If you try to keep it varnished, simply replace the paint (pigmented oil) with clear Jupex varnish. (should be lightly pigmented with the brown pigment)

-Kitchen counter-top maintenance, beech or oak: Scrape it, sand it with 220 paper, oil with Jupex 45 to saturation-point. (This is the best treatment we have ever heard of, way better than other methods!)

Roof done, Peter and Darragh makes final check

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 Peter and Darragh, passive house carpentersroofwindow 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.

New and old, passive renovation from 1860 and new passive house 2013

The old and the new can live in good harmony- The grey house that was built in 1860 got the passive house treatment with 170mm of extenal insulation behind the ventilated fasade last year. The red house is brand new, a standard Scanhome Skagerrack 304 with 355mm of wall insulation within the timber frame constuction.

Seasonal store of solar heat, over 100 degrees

This Monday was quite exiting before we got the 23.000 liter seasonal store tank in the basement connected to the 50 m2 of solar-panels on the roof of the old building. The small tank of 3.300 liter (located in the stairwell of the 1860 house) could not handle the heat generated by our solar-collectors. We had 110 degrees water coming down and it was coming close to boiling. We had to ask the tenants to leave the heat on and open the windows to cool off the system for a while.

On Tuesday 13th of May,  Åke Häggmann, Peter and Tobias connected the finned copper tubes in the bottom of the tank. Finally there is somewhere for us to pump away the superfluous heat from the roof. It will be interesting to measure up the various flows and temperatures to analyze the functionality of the system. This is done by Dr. Shane Colclough as part of the EINSTEIN research-program.

It is a pity that the collectors are shadowed by the Library-building across the street for the winter months, but of course, that is partly the reason for building a seasonal store in the first place.

Passive apartments after 2 weeks

The super-erection-team Flaherty and Goaley with Peter, John, Darragh, Ruadhan, Adrian and Cathal are plowing on. After two weeks of construction the roof is nearly completed with clay tiles and all. A good bit of extra seal-effort around the roof windows are always done by Scandinavian Homes when we install these problematic windows. (all roof windows are, this is not connected to any particular manufacturer)

Triple glazed roof windows are sometimes supplied with an extra frame with a bit of foam for insulation of the frame. But we see major flaws with this. Rainwater and wind penetration. A hopeless “apron” is supplied with the kit and this is supposed to keep wind and rain out. Worst possible detail, just a cover-up so you cannot see how poor the methods of sealing are. This is of extra concern in well insulated houses where massive amounts of roof insulation will soak up eventual water for years. To make it worse, the vapour barrier on the inside of the insulation will prevent detection of eventual water-leaks. Problems will be hidden for years and the risk is that the roof is rotting away under the roofwindow(s). 

Soyabased Sica Maestic seal is injected around the roofwindow with flashband sealed with hot-air gun.

Scandal bathroom floors leading to destructive insurance costs…

Why are not all wet-rooms (bathrooms, shower-rooms and utility-rooms) tanked and equipped with a floor-trap? How many millions are wasted on repairing water-damages in Ireland every year?

What is the authority, the competent, well-educated people at the NSAI doing about this? Why do they have to follow antiquated sub-standard British standards?

A floor-trap together with a simple tanking of all wet-rooms before the tiles are installed is all it takes to prevent future damages.
