In order to protect the attic space against moisture, air intake openings at the eaves and exhaust openings in the gable walls or in the ridge should be made., e.g. raised ridge tiles for ventilation or ventilation ridge fireplaces.
Bipartite roofs with a rafter structure
In flat roofs with a high attic, with a rafter roof airspace temperature (attic) should be almost equal to the outside temperature. To make it possible, the air space of the flat roof must be adequately ventilated (supply and exhaust openings). In addition, proper warming is necessary …
Principles of thermal insulation of double flat roofs
The table lists the minimum thickness of thermal insulation for a flat roof according to the current thermal protection requirements for buildings. A Ceram rib-and-slab ceiling was adopted for the structural layer of the double-section roof, reinforced concrete slab and a wooden beam ceiling with a soffit. The types of ceilings selected for the analysis are present in buildings …
Ventilation of two-section flat roofs
Ceilings
The flat roof protects the internal rooms of the building against rainfall and temperature changes, that is, the influence of the external climate. The flat roof consists of many layers with different functions. On the supporting structure (ceiling) there is often a vapor barrier (vapor barrier), then a thermal insulation layer (thermal insulation). Between …
Coating technology on plastic substrates
Why are plastics coated?? Coatings on plastics may be necessary for the following reasons:
1) this procedure is often cheaper than the necessary change of the color of the material;
2) manufacturing defects can be covered, like so far, streaks and stripes;
3) …
Elements of the hydraulic system of the boiler room
Because of destiny, devices placed in boiler rooms can be divided into four groups:
1) heat and energy transfer devices,
2) regulating devices,
3) control and measurement devices,
4) safety devices.
The most important hydraulic devices are listed in the table, which can be attributed to each of the …
POLLUTANTS EMITTED DURING THE COMBUSTION OF FOSSIL FUELS
To the primary pollutants emitted, when burning fossil fuels belong:
- carbon dioxide (C02),
- Sulphur dioxide (S02),
- nitrogen oxides (NOv), which they include: nitrogen dioxide (N02) and nitric oxide (NO),
- carbon monoxide - carbon monoxide (CO),
- dust …
Window handles
Window handles are generally just plain ugly. However, it is increasingly possible to search for the original ones, deviating from the ugly standard.
In the aesthetic consciousness of users, window handles play a rather subordinate role. Single-family houses and apartments are renovated from time to time …
Why is it worth using a complete thermal insulation system?
Thanks to the use of Fasrock Max boards with a very good thermal conductivity coefficient λ = 0,037 W / mK (for boards with a thickness above 100 mm), ECOROCK MAX provides the best insulation of external walls of buildings
As a result, a very high thermal resistance R = is obtained …
