Errors insulation of the attic: where are moisture, mold and freezing

Huge empty attics of private homes saw me practically free living space. Threw insulation between rafters, bottom hem with plaster, live and be happy life. This, if done correctly. My friend made sure that insulation should be altered.

The novel is far from the building and completely trusted brigade masters. Its role was limited to the delivery of materials and payment of work done. In winter updated loft left in a rough finish. At first, it was warm, then at the ceiling tread frost.

- How much will lay the insulation? - I asked one of the masters.

- They say that we have in the region of 200 mm is sufficient, - Roman suggested.

We agreed on two hundred. Brought. Laid. The height of the rafter 175 mm builders are not confused. Mineral wool somehow shoved, pressed lining and forgotten. But in a compressed state, the material never ensure that insulation, that laid the manufacturer. And this can be avoided. Even if the height of the rafters less than the thickness of insulation material can be placed freely.

Rafters small height does not limit the thickness of the insulation. When their section is not enough, the bottom bar fills. Better perpendicular to the rafters. Mineral wool in this case lies with the overlap, we can say that there is no cold bridges. Immediately put the bars with the right step for fixing the cladding and "kill two birds with one stone."

Roman had to remove the trim, alter insulation fittings and mount everything back. And this problem does not end there.

A miss is as good as a mile

The highest blowing and frost appeared in the place of junction of the roof to the walls. After dismantling it turned out that the roofing insulation ends of the inner edge of the wall. In fact, the street directly in contact with the room. A simple error - "very nearly brought the mineral wool." As a result - already in the first winter blowing and freezing. Still a little bit and wait to visit the mold.

Insulate the roof - we deduce mineral wool at least until the outer edge of the wall. However, in the history of the novel, it was not the worst problem.

Rain and no snow, and heat insulation "sweating"

When dismantled the paneling, they saw that all the raw mineral wool. Although rainfall last week was observed. As it turned out, the reason is in violation of the ventilation. Steam and waterproofing tapes were in their places. However, the fact of under-roof space is ventilated at all.

You will recall that the insulation between the rafters strangled to the limit. He held up a diffusion film. Condensate instead effloresce outwardly flocked on the surface and seeping down. In waterproofing film should always be ventzazor. Otherwise normally it will not work.

Once transferred down 50 mm insulation, problems solved. The target remaining trusses 150 mm mineral wool. Below under the film was slit to 25 mm. Rockwool ceased to bulge upward, so loose and the gap over the film. The roof got really warm and began to "breathe."

If the article was helpful, please send me a couple of cubes of insulation on the arrangement has its home. Just kidding, that's enough, and Laika. Thank you for reading.
