The attic is space between roof and ceilings of the premises located below. All use this space in own way - someone arranges wardrobe there, someone stores old things, and someone will make full repair there and equips office. Regardless of ultimate goals the attic needs to be warmed. It will allow to avoid considerable heatlosses and rotting of wood beams of overlapping.
The choice of heater for the attic in owner-occupied dwelling
Before buying any material for warming, it is necessary to get acquainted with technical characteristics of all possible options. Most often the choice of owners of the house falls on expanded polystyrene or mineral wool as it is the simplest to mount these materials. Both the first, and second options have low acoustic permeability that too is important, and low coefficient of heatlosses However, expanded polystyrene, especially extruded, loses to mineral wool in environmental friendliness, and the most important, in vapor barrier. The low vapor barrier of this material will lead to rotting of wooden overlappings subsequently.
Indicators of mineral wool are ideal for warming of the attic. As it is produced from rocks, its characteristics are full reflection of all advantages of stone: the .ona is completely eco-friendly, interferes with burning, has good noise-insulating indicators, and due to fibrous structure perfectly ""breathes"" and does not suppress natural ventilation of the attic. As for its heat-insulating properties, the minvata layer in 100 mm is equated to brickwork 1170 mm thick. For this reason warming of the attic mineral wool - the best option from possible.
As it is correct to warm the attic
First of all it is necessary to count the total area of warming minus window openings if they on the attic are available. Having separated the received square at the area of minvata in one packing, you decide on the necessary number of packs. After that it is necessary to carry out preparatory work, namely to establish parobaryer. Half of the attic is ceiling for all other rooms. Warmly living rooms, rising upward, it is condensed on heater layer. This deposit badly affects it - heater becomes wet and loses all the useful properties, and at long influence of moisture gradually collapses. In addition, such condensate has negative impact and on load-carrying structures.
To avoid this trouble, it is necessary to lay on overlapping by the first layer waterproofing material and only after that to start laying of mineral wool. This procedure is necessary in case it is used the minvat in plates as its rolled option already from manufacturer is issued in special waterproofing covers. It is also desirable to provide ventilation on the attic.
Laying of minvata has to begin from that wall that is opposite to door. Plates or rolls keep within densely to each other, and their cuts are glued with adhesive tape. Strongly it is not necessary to trample down heater as it will worsen its useful qualities. In conclusion of works floor is mounted. It can do baht plywood, chipboard or similar materials.
And here the order of warming of roof differs a little. For warming of slopes it is better to use not rolled option of minvata, but sheet or in the form of plates - they are less showered over time. Besides, the waterproofing course in this case has to be laid on mineral wool. Thermal insulation keeps within between rafters, is closed by waterproofing material and is fixed by cross rails. The same rails will become support for strengthening of sheet decorative materials subsequently.
