Additional insulation wind? Here are tips on additional insulation of roof and energy conservation as well as moisture and choice of insulation for additional insulation.

Supplemental insulation of roof and wind - Tips

An additional insulation of the ceiling and the wind can provide a lot of profits for house and homeowners. One of the more important reasons for the additional insulation of the roof is to reduce energy costs. Additional roof insulation is the single best thing you can do to reduce the heating costs of a house. It's both cheap and efficient.

About 15-18% of the heat from a normal insulated house disappears straight up into the ceiling. That figure can easily be reduced considerably by adding an extra layer of insulation to the wind. It's an investment that pays off quickly and is immediately visible in the wallet.

Energy Savings

It is possible to make major energy savings by adding the wind to the wind. Heat rises as known upwards, and by stopping air through the ceiling and into the roof rails, heat is also prevented from disappearing from the living spaces in the house. Many older houses have poor roof insulation. It is not uncommon with an insulation thickness of only 100-150 mils. This applies to mineral wool. When it comes to the classic sawdust, the layer usually stores about 150 - 250 mm thick. By adding 25 centimeters, 2,000 kWh hours per year can be saved in heating, in a normal sized villa. It is still not as thick with insulation as the new building norm indicates. There are values ​​of at least 500 mm for wind bellows and 400 mm for sloping ceilings. Another advantage is that it also gets cooler in the summer.


One of the difficulties that needs to be seen when a wind is insulated is that there may be moisture on the wind. This is because the wind is getting colder than before, when hot air penetrated through the insulation. The moisture can in turn lead to mold and rot. Whatever material you isolate with, the wind must be kept well ventilated. Alternatively, a steam brake is required either a vapor barrier inside the baffle.

Which insulation

Insulation for the wind comes in bulk and as discs and can be made up of several different materials. The most common are stone and glass wool and cellulosic insulation materials. The loose litter has become popular in recent years. It blows easily with a machine and lays itself like a thick rug on the wind. A major advantage of solvents is that there is no risk of cold bridges, as there are no joints to take into account. Slices of mineral wool and glass wool are otherwise the most common option still, and something that the handy can put in. There is also cellular plastic as insulating material for winds. The cellular plastic consists of small control beads surrounded by an air layer in cement. What is best is a matter of taste, taste, wallet and the insulation already in the house.

Thinking of

Consider the house's precautions carefully before the additional insulation is carried out. What is technically possible and what insulation and what thickness fits and is most effective? All houses do not have a cold wind where it is easy to insulate. It can make the job more clever than it is thought from the beginning. Also consider the thickness of the insulation that is most beneficial. Please contact the municipality's climate and energy advisor for specific advice. Building permits may be required for additional insulation of houses in special cases. Please double-check with the municipality. Further information on additional insulation is also available from the Swedish Energy Agency.

Rules can be changed, so always visit the Tax Agency's website for detailed information about which services are included in the root deduction.
