Polyurethane foam is becoming one of the most demanded heaters, its advantages in practice have been felt by many developers and owners of private houses, industrial and office buildings. This material is used for thermal insulation of almost all structures - walls, sex, ceiling, overlapping partitions, as well as roofs. Insulation of the roof from the inside - one of the options for using PPU, which provides excellent sound, heat, moisture-proof surface.
PPU thermal insulation - features
PU foam is applied to surfaces using a special installation. This insulation is obtained by combining two components - polyol and isocyanate, mixed in a special container, after which the mixture is sprayed onto the surface through a spray gun.
When it hits the roof, the foam instantly grasps to the base, creating a durable coating without gaps and gaps. The use of PU foam allows you to get rid of seams and joints. Foam penetrates hard-to-reach places without any problems, covers cracks with a dense layer, holes, other surface defects.
Liquid polyurethane foam instantly solidifies in the presence of air, forms a crust, foam-like. The weight of this insulation is minimal - PPU on 90% consists of bubbles, gas-filled. Even a layer thick 10 cm and more does not have a significant load on the heat-insulated structure, but at the same time makes the structure more durable and stable.
It is possible to carry out thermal insulation work both from the outside (on flat roofs), and from the inside - between the beams (pitched roofs). Insulation from the inside can be performed at any time of the year, regardless of weather conditions. Important, so that the air temperature inside the attic is positive.
The process of insulating the roof between the beams
Work on the application of heat-insulating material consists of several stages:
- surface preparation - removal of loose finishes (if available), dust removal, mud;
- preparation of a mixture for spraying - combining components in certain proportions in a special container;
- adjustment of equipment operation and spraying of polyurethane foam on the interbeam space;
- if necessary, after the first layer of foam has dried, a second layer is applied to create the required thickness of insulation.
It is necessary to spray polyurethane foam with a uniform dense layer, to ensure the required thermal insulation characteristics of the insulated surface.
You can order the service of thermal insulation of the PPU roof on the website of the "Advance" company https://edvans.com.ua/uslugi/teploizolyatsiya-kryish/. Work on the application of polyurethane foam to the roof must be carried out by qualified specialists, who are fluent in this technique. This will ensure the quality and durability of the created thermal insulation coating..
