Similar problems usually arise in those cases when you buy an already finished house and do not know anything about construction and finishing. After all, when building a roof and its ceiling, you can not save on specialists and materials, and anyone who has been in this situation will tell you. But, one way or another, and the roof is literally crying, and condensation is visible to the naked eye. Why the condensation is formed in the attic and how to proceed in this situation, we will consider in this article.
Cause of condensation in the attic
Regardless of whether you have a cold or warm attic, the condensate will form for one of the reasons listed below:
- The insulation of the roof was poorly made or it is simply weak;
- at installation builders ignored the so-called ventilation under the roof at all;
- During the vapor barrier or waterproofing, mistakes were made;
- The slopes and skylights were unprofessional.
In other words, the condensate was the result of technological disturbances during operation. Also, many people try to save on materials. This is a gross mistake, as fixing it will cost you much more than the initial expenses for masters and good materials. For example, under the roof put the most common layer of impermeable film for waterproofing. On its smooth surface will be created just ideal conditions for the formation of condensation in the cold attic, since it simply has nowhere to go, except to drip on a layer of insulation or cornice.
How to eliminate condensation in the attic?
Now that we know the main reasons for this problem, we can proceed with its elimination. Below are the methods how to eliminate condensate in the attic, depending on the underlying cause.
- The first thing you can do if the attic is condensation, consider the issue of air exchange. It must be permanent and in the whole volume of the attic. Then the condensate will instantly dry out and stop gathering in droplets. For these purposes, you need to invite a specialist with a thermal imager and see a picture with irregularities. Then once again turn to the scheme of competent laying of the roof. It is likely that you will have to do some redevelopment of dormer windows, use an additional layer of insulation or make ventilation vent.
- What if the condensate in the attic is the result of using substandard materials? Most likely, the solution to the problem will be the replacement of conventional film with a special membrane layer, which prevents the formation of condensation. Such a material allows moisture to flow out, but at the same time it prevents its penetration inside, and due to a fleecy surface, the droplets can not form on the surface.
- If nothing helps, you will have to completely change the crate and vapor barrier layer. What can be the problem: there is no proper outflow of air and its circulation, which contributes to the accumulation of dampness. And it means that it will be necessary to engage in the arrangement of this unit with a competent specialist and provide those same 40 mm for ventilation gaps,
do not forget about the perforated spotlights in the eaves area. And the layer of insulation itself should be laid exactly on the rafters and under the crate (controllable) when installing the shingles. Then nothing to drip on a heater will not be and dampness will not take unawares.
All these methods will prevent permanent dampness and thus prolong the life of the floors, and you will be provided with dryness and comfort in the house. Among other things, attic arrangement can pull up to 20% of the total value of the house, so it's more profitable to do everything in the mind initially, than to do the work on the errors later.
