Heat losses through the surface of the building sometimes reach 25%. To fix the situation will qualitative insulation: the surface will become warmer, the cost of heating will be significantly reduced, the microclimate in the room will improve. A lot of insulation materials have been developed, among them, foam foam is especially in demand.
What do you need to know about penokleks?
Penoplex is an improved extruded polystyrene foam . The material is obtained by foaming the closed cells. In fact, the main component is air. The products are produced in the form of slabs with a length of 0.6-1.2 m. The advantage of mounting is the possibility of fastening the sheets together by means of joints.
The material serves as a thermal insulation foundation for the foundation, floor, walls and roof. Such a heater with a thickness of 2 cm for its thermal characteristics replaces a 4 cm mineral wool board, a board made of wood of 25 cm or a brickwork of 40 cm. A long service life is due to zero water absorption, no biodegradation, that's why you can not be afraid of mold , putrefaction and fungi. Advantages of insulation on the face: very low thermal conductivity (25% lower than that of ordinary polystyrene), ecological compatibility (suitable for internal and external finishing), low vapor permeability, durability, does not support the combustion process.
Depending on the type of surface, the purpose of the room, heat engineering calculation, you need a particular penopollex. The thickness can vary from 5 to 30 mm, density - 30-45 kg / m3 sup3.
How to fix a foam-insulator to the wall?
To disadvantages of the penopolix is a fairly low adhesion, but with further processing the finish surface finish is carried out without problems.
Before you begin to fix the outdoor insulation for the walls of a penopolix, you may need a vapor barrier . Condensate at the dew point appears when the inner insulation, so the steam film with the vnutryanka necessary. You will need a foil base, a shiny side inward.
Warming of the room from the inside begins with the preparation of the surface, it is recommended to level the walls beforehand. This approach will significantly reduce the time for finishing. Then the working zone is primed. Mounting the insulation foam on the wall begins from the bottom corner. Initially, the sheets are "planted" on a special glutinous mixture, adhesion can be improved with small cuts from the side of the wall. Grease is made in the central part and around the perimeter of the plate.
After drying, joints are sealed, it will also be necessary to fix the sheets with the help of dish dowels (umbrellas) in the corners and in the center of the plate. For dressing, install the heater in staggered order. The material is easy to cut, so when finishing the protrusions, niches and depressions there will be no difficulties. The joints are often sealed with foam and a special tape. Especially high heat losses are fixed in the end, corner parts of the room, in the areas of adjoining balconies and loggias. The panel walls simply need to be insulated with this kind of extruded polystyrene foam.
The sequence of actions when creating a "wet" facade is similar to internal warming. The facade is subjected to more aggressive influences, therefore it is recommended to install an air gap. Otherwise, the glue base will collapse more quickly. Difficulties often arise with the finishing of openings and ledges. To achieve a complete fit of the elements, use washers.
The advantages of penoplex are obvious. Perhaps the only thing that can embarrass the buyer is the price. The heat insulation will cost you a little more than the usual eustrofoam expanded polystyrene, but the price / quality / durability ratio are worth it.
