How to perform wall insulation from the inside

Comfortable and cozy in the house, when you feel physically and mentally warm there. This is the physical and must be protected. There is no stove in today's homes that can be flooded on a cold evening. How to make the house warm if central heating is not enough. It is best to insulate the house outside. And if the fourth floor? Comes to the rescue wall insulation from the inside. This method has its drawbacks: it is difficult to avoid condensation between the insulation and the wall, the area is reduced, it is difficult to lay cables under the insulation, and additional finishing works appear. However, the heat in the house is worth it to insulate the walls from the inside.wall insulation from the inside

Immediately the question - how to warm?

Warming can be made of mineral or glass wool, foam plastic and its varieties, cork panels. You can do everything with your own hands, and all this is not so difficult.

If the walls are insulated from the inside out to the mineral water, then it is best to use hard mats. In this case, it is not necessary to align the walls, because for laying insulation you will have to mount a frame of bars or metal profiles.Due to the frame walls are aligned. The guides are installed in 60 cm increments, which allows laying the mineral wool between them and comfortably “stitching” sheets of drywall, 120 cm wide. Be sure to use a substrate for waterproofing, it prevents moisture accumulation, which destroys the insulation and the wall structure. After mounting the drywall, close up the joints of the sheets, putty and finish.wall insulation inside the foam

Styrofoam

It is more convenient and more reliable to perform wall insulation from the inside with foam plastic. Today it is one of the cheapest thermal insulation materials, but in its characteristics and quality is not inferior to new and expensive heaters. Installation of foam sheets on the wall is quite simple and easy - another advantage of this material. But some nuances still need to be known. First, the wall must be prepared - to level with plaster and putty (on brick), and simply enough putty - on concrete walls. If the insulation of the walls from the inside of the foam is carried out during the repair, then it is necessary to remove paint or wallpaper from the walls, remove defects, repair cracks and only after that level out.The coatings prepared in this way are grounded, the waterproofing material is laid (so that moisture penetrating through the walls does not get onto the insulation) and then polystyrene is attached. You can fasten the sheets with screws or dowels (umbrellas), but it is most convenient to use special glue, which is quite enough. With the help of a spatula-comb the glue is applied only on the wall and clean sheets of foam plastic are laid on it, as densely as possible. Any gap between the sheets is a “cold bridge”. A vapor barrier material is laid over the foam, protecting it from moisture inside the room.wall insulation foam inside

Penoplex and polyurethane foam

Warming of the walls from the inside can be done by penoplex - extruded polystyrene foam. It has high strength properties and has a very low water absorption - the most important quality for insulation There is also polyurethane foam. It is as close as possible to the wall (no air gap) and allows to reduce the thickness of the insulation by 2-3.5 cm. Working with these materials is identical to working with foam. May your home always be warm!
