Thermal insulation of the ceiling with mineral wool ( mineral wool ) - step by step instructions

conditions of the Russian climate with short summers and long frosty winter creates the need for additional measures for insulation of residential buildings.One of them is headlining mineral wool.This procedure eventually will help not only to increase the term of conservation of heat in the rooms, but also to avoid the appearance of mold and mildew on the ceiling, arising from the condensate, which is formed as a result of the direct collision of cold and warm air.

Insulation of mineral wool ceiling

Warming ceiling in homes is recommended with the use of mineral wool is becauseit is non-toxic and environmentally friendly material, is not subject to rot, fire-resistant, it can not start insects and rodents.

most important thing - it has excellent heat - and sound quality.Producing mineral wool in the form of rolls and slabs.Also, when you select should pay attention to the foiling of mineral wool - well, if one side of the roll or the plate is covered with a layer of waterproofing foil.If this layer is not present, then, ideally, you need to purchase a few rolls of foil foam.Instead, you can use a thick plastic film.As a suitable vapor barrier asphalt.These materials are essential to maintaining the dryness of the mineral wool, becauseMoist insulation loses up to 40% of heat-insulating properties.In addition, you will need screws, fastening with a wide hat made of plastic, counter-glue for mineral wool, profile, and suspensions for the profile, stationery knife, staple gun, nails, screwdriver, hammer and tape measure.

most common thickness of the layers of mineral wool produced is 10 and 5 cm at the ceiling insulation is sufficient insulation layer 10 cm thick, in particularly difficult cases -.. 15-20 cm According to the method of work is divided into insulation of internal, external and combined.

Internal insulation

necessary internal insulation of the ceiling is most common in houses of several floors or penthouse, as well as for urban apartments.The entire scope of work consists of the following stages:

  1. Crate ceiling - can be made of boards section 30-40 x 100-200 mm (width of the board depends on the thickness of the insulation layer) or metal profile.Lathing fixed to the ceiling by means of screws or nails, the distance between adjacent portions should be about 50-60 cm, depending on the width of the mineral wool used.

  2. for finished crate fastened waterproofing layer - cut strips width of 50-60 cm plus a tolerance of 5 cm on each side, ie,final width will be 60-70 cm. These strips are attached to the counter-wooden crate or screws to the profile.

  3. Next is laying mineral wool and its fixation with glue or staple gun to the ceiling, with a large layer thickness - to the crate.

  4. next layer - steam, with glassine paper.It is mounted on mineral wool with a stapler.
  5. finished structure shall be secured transverse locking or counter-profile.

  6. procedure of internal insulation is completed, the next step is mounting furring plasterboard panels or stretch ceiling.

external insulation

This method is used in private homes with attic.Compared with internal insulation of this kind is easier to implement and takes much less time and effort.So:

  1. entire attic area covered with a layer vapor barrier material (asphalt) overlap width of 5-10 cm, glued joint place with adhesive tape or adhesive tape.
  2. from boards section 30-40 x 100-200 mm (width, as well as with internal insulation depends on the thickness of the mineral wool layer) stuffed crate.The distance between adjacent beams is calculated according to the roll width or insulation boards.

  3. recommended laying foam layer thickness of 5 cm When an external thermal insulation on the ceiling vapor barrier. Thanks to him, the level of the vapor barrier is increased significantly.

  4. foam lay on mineral wool layer of 10-20 cm. It is important that when laying between layers of insulation and beams crates had no gaps.

  5. If mineral wool with one side covered with foil, then the flooring produced so that this part was on top.In this case, an additional sealing layer is not needed.If mineral wool plain, then top it thoroughly cover layer of waterproofing material overlaps, joints glued with tape or duct tape, and all counter-fix.
  6. further mounted a floor made of wooden planks, particle board or OSB.

Combined insulation

Combined insulation - mineral wool is mounting on the ceiling and on the inside, and from the attic.This method of insulation is characteristic of the premises in which it is necessary to maintain an elevated temperature for a long time - saunas, steam rooms, etc.

Tips

In conclusion a few words about the little tricks that can help you avoid many problems after the thermal insulation of the ceiling with mineral wool:

  • · The fine fibers that make up the mineral wool, in contact with exposed skin and the respiratoryway cause itching and irritation.To avoid damage to health, it is necessary to use special clothing and a respirator.
  • · When using crates of metal profile, may subsequently prove that the corners of the ceiling continues to flow through the cold air.To eliminate such a problem, after fixing the metal profile to the ceiling all the corners carefully poured with foam.
  • · Due to errors in the calculation of the mineral wool layer thickness may exceed the width of the crates.In this case, wooden beams nailed additional bars.If the crate from the metal profile - will replace hangers or reduce the layer of insulation.
  • · When laying mineral wool is strictly prohibited its compaction and compression - this leads to a decrease in the number of air bubbles inside the heater and, as a consequence, the loss of thermal insulation properties.
  • · At the installation sites of point lighting is necessary to provide space for air circulation in order to avoid problems with their constant burnout.
  • · Most suitable for fixing metal profile screws are part of the section of hardened steel.
  • · Determine the current state of the insulated ceiling, you can use this device as a thermal imager.When enabled on a red screen indicates the location of the cold air passage.
  • All of the above is intended to facilitate as much as possible and to optimize the financial and physical costs of ceiling insulation mineral wool.However, for best results, should seek the advice of professionals.They will help to make the correct calculations required thickness of the insulation layer and, on this basis, calculate the final amount of the material and its cost.Often such companies cooperate directly with manufacturers of materials for the insulation, which may result in additional cost savings when purchasing.
