The construction of attic in residential buildings was first spoke in the 17th century. The attics are rooms located under the roof and fully adapted for housing. To illuminate the attic, as a rule, windows built into the slopes of the roofs are used.
To date, along with wooden attic windows, increasingly popular, due to increased strength, excellent thermal insulation properties and tightness, acquire plastic windows. One of the positive qualities of plastic attic windows is resistance to various atmospheric phenomena and corrosion formation.
In addition, plastic windows have a number of advantages over wooden: the ability to fix the open window in various positions, provides the necessary circulation of fresh air, and the design itself adjacent to the window opening, guaranteeing complete tightness during bad weather. In order to protect the room from ultraviolet rays, special reflex glasses are used in the attic windows.
When choosing plastic windows, you need to pay attention to their main components: profile, double -glazed window and accessories. Two or three glasses with air chambers are used in double -glazed windows. Improving the soundproofing properties of the double-glazed window is achieved due to the installation of a triplex or outer glass with a thickness of 6-8 millimeters.
Triplex is safe glass. When it is broken, the fragments do not fly apart, but are held with a special film.
Installation in the windows for the attic for hermetic double -glazed windows allows you to achieve several more positive points: due to their use, the noise level in the room can be reduced to fifty dB, and heat losses are reduced up to sixty percent.
Competently selected double -glazed windows, provided that the rules of operation of windows should not freeze and fog at any temperature, even very low.
Polyvinyl chloride (PVC) from which a profile for windows is made is a synthetic polymer related to the thermoplast group. In addition to high heat – and sound insulation, windows from PVC profiles differ from wood windows with lightness and ease of care. To achieve a high degree of strength of a window from PVC profile, a steel insert should be reinforced.
Plastic windows are ideal not only for creating comfortable living conditions, but also make it possible to achieve an unusually cozy atmosphere in the attic boards and offices.
Installation of attic windows should only be carried out by professionals.
