Energy Saving

Energy efficiency in buildings is an international demand. Therefore the developed countries have already taken measures that enhance building insulation aiming at saving energy. As part of this effort in our country, since November 2010, an Energy Performance Certificate is requested for each building sold or rented (February 2011).

The thermal and visual comfort of the occupants of a house provides a comfortable living and simultaneously achieves energy saving. Thermal comfort is achieved with thermal insulation of the main and secondary walls, the roof, the parking space (if any) and of the door and window frames, while the visual comfort, the visual contact with the external environment and the provision of the necessary light for uninterrupted work within a building is achieved through the transparent openings of the space, i.e. the door and window frames, which in a conventional house cover about 8-10% of the total external surface (the building envelope).

In an old house, the intervention in the heat loss and the increase of energy efficiency can be made retroactively and relates to the insulation of facades, walls and frames. The replacement of door and window frames, which are responsible for about 40% of the heat loss of a home, is the fastest, easiest and most economical solution, which also yields excellent results, if the appropriate materials are selected and properly placed.

All modern DAUWIN® frames, made out of aluminum, plastic or wood, ensure the necessary insulation, because they are manufactured in accordance with European and international standards, thereby contributing directly to reducing energy consumption.

In addition to the frames, an important role also play the glazing in double or triple glass panes – depending on the cold that the building is exposed to –-and the external mobile insulations, such as shutters, roller shutters, etc.

Through the glazing (windows, glasses), heat is lost during the winter months or heat enters in the warm months of the summer. Replacing the ordinary glazing with energy efficient ones contributes to the reduction of the energy consumption of a building without significant expense. In our country, since 1979, the use of double glazing has been mandatory. However, today it is imperative to replace these old double glazing with new, energy efficient, double glazing, which together with improved quality of the frames, eliminate air leaks, protect from sunlight, contain the necessary heat inside the building and, ultimately, will dramatically reduce heating costs in winter and cooling costs in summer, while achieving thermal comfort and multiple environmental benefits.

Thermal Insulating Door & Window Frames

The insulating capacity of a frame is referred to as thermal transmittance, which is marked by the manufacturers with the letters K or U. Furthermore, the components comprising a window frame contribute to its total thermal capacity, too; both the mounting parts that seal the frame to the openings and help its proper use, as well as other sealing components such as the perimeter rubbers. However, the properties of even the most insulation efficient window frames could only deliver very little, if the frames are not positioned correctly. After installation, an inspection must be carried out to detect and to correct any omissions.

Thermal Insulating Glazing

Today, a significant range of energy-efficient glazing is provided covering all kinds of buildings, depending on their use and size; also the amount of money that any client can allocate is also diverse. Single, double, double low emission, sound proofing, sound absorbing, heat insulating glazing for all functional and aesthetic demands of a home, offering a wide variety of choices, thereby ensuring extremely high levels of thermal comfort inside the house. The client should learn about all the options offered, in order to choose what is suitable for the needs of a house and its occupants. One is certain: the cost of the initial investment will be amortized rapidly by the energy saving that will be achieved.
