Can windows contribute to architecture?
Yes. On the inside, they essentially determine whether we feel good, whether the house or building "functions". On the outside, windows can structure facades, make them appear smooth or three-dimensional, give a house or building its distinct flavor via large-panel glazing or Georgian bars.


Are all plastics equal?
No. The great advantage offered by plastics is that they can be custom-engineered for a particular application. A slight change in a plastic's molecular structure can result in substantial changes of its properties.


What are plastics?
Plastics are man-made synthetic substances, yet they emulate materials found in nature featuring valuable engineering properties. Since the days of the first synthetic material, plastics have evolved from the cheap mass-produced products of yesteryear to a group of highly specialized materials capable of solving a multitude of unusual problems. Modern plastics are incorporated into the design of airplanes, radio telescopes, automobiles, and artificial lakes.


What is U-PVC?
U-PVC stands for unplasticised polyvinyl chloride. It is a thermoplastic obtained from salt and crude oil. U-PVC powder is produced in a series of process steps. U-PVC is one of the most adaptable and widespread plastics offering marked durability.


Where is U-PVC used in construction?
U-PVC is an approved construction material and one of the architect's mainstays. U-PVC is as common in pipes, roof gutters, facade cladding, roofing, light-diffusing walls, interior fixtures, cable ducting, and signs as it is in windows and rolling/folding shutters. Its long service life makes it both an economical as well as environmentally safe solution. U-PVC is wind- and weatherproof, heat- and frost-resistant, maintenance- and user-friendly for the life of the product.


Modern plastics have become the leading material in restoring historical buildings. Isn't that somewhat of a contradiction?
No. U-PVC windows are ideal for old buildings. The windows of old buildings are frequently in poor condition. It is only natural that the architect resorts to modern materials more than others. State-of-the-art construction physics achievements are incorporated in a building's most susceptible part, insulating against noise and lowering heating and maintenance costs in the long run. A highly variable window system makes it possible to reproduce virtually any window design so that a historical building retains its distinct appearance. Thanks to the molding properties of U-PVC profiles, practically any type of arch can be reproduced economically.


What about ornamented windows?
This refers to strips, columns, capitals, base members, etc. mounted on top of the profile, as was the usual practice about one hundred years ago. A large number of ornamental items are commonly sold. The important thing is that the function, frame width, relief, transom, weather bar, rabbet etc. are in keeping with the original appearance.


Aren't U-PVC windows all the same?
No. Even outwardly identical windows can be completely different on the inside. The quality of the material, stability and durability, design and processing quality are different as are profile design, sealing, and system variety. Expert installation and integration are of paramount importance as well.


How strong are Eurobuilt windows?
Eurobuilt U-PVC profiles are reinforced with large-sized metal profiles. Their static strength conforms to the exacting requirements of skyscraper construction. The windows remain tight even when subjected to driving rain or storms.

They conform to all relevant standards and guidelines, both national and international. Added advantage: their unsurpassed corner strength. Welding a the corners of Eurobuilt profiles is done directly between two high-impact strength U-PVC surfaces, ie. without using any adhesive. Owing to this homogeneous joining technique, the finished product offers the mechanical and aesthetic advantages of a unit made from one piece.


Are there DIN Standards for windows?
Yes. They form the basis for high-quality products, governing everything from profile manufacture and quality to installation. Many performance specifications are not merely satisfied but even surpassed by Eurobuilt U-PVC window profiles.


What about the current popularity of Georgian bars?
The decisive questions is: does the window fit in with the building's original architecture and surroundings? If Georgian bars are characteristic of a building's architecture or surroundings, then they should be used. However, we generally advise against fitting large-panel glazing in modern buildings with Georgian bars.


Are there differences in Georgian bar windows - also with respect to pricing?
Georgina bar windows are offered in various designs which differ greatly in intricacy, not to mention price. Eurobuilt window systems include genuine Georgian bar designs featuring individual panes as well as economical Georgian bar grids fitted onto double glazing panes.


How much can I expect to save in heating costs?
In comparison to old, single-glazed windows, heat loss per unit of glass area can be reduced to less than one-fourth. To achieve this, special thermal insulating glass is required. Yet substantial heating savings can be achieved with standard insulating glass as well.

For example, heating oil consumed during the heating season (per square meter of glass area):

Single glazing 60 liters
Insulation glazing 30 liters
Triple insulation glazing 20 liters
Special thermal insulation glazing 14 liters


A lot of condensation often forms on old windows in winter. What about modern windows?
Condensation and frost patterns form on single glazing, too, because the glass pane is comparatively cold, thus causing moisture in the room to condense. Condensation is virtually eliminated due to the high thermal insulation capability of modern window profiles when combines with insulation glazing.


How are the noise attenuation characteristics of a window determined?
On the basis of the difference between outside noise and target indoor noise level. Insulation rates of 60dB can be obtained when Eurobuilt window systems are fitted with special sound insulation glazing. Apart from tightness, profile design, pane thickness, and pane spacing, the overall design plays a substantial role in noise insulation.

eg. Noise reduction levels can be attained:
To 1/16 with appropriately glazed recessed standard windows
To 1/24 with appropriately glazed flush-mounted standard windows
To 1/32 with appropriately glazed composite windows
To 1/64 with appropriately glazed casement windows



Can the various noise pollution levels on the individual sides of a building be compensated for and a uniform appearance still be retained?
Yes, that's one of the main advantages offered by a window system concept. There is a range of various noise reduction designs featuring an identical outer appearance to choose from in order to cater to the respective outside noise level. It is also important what the room is used for. It is not generally necessary to go to the same trouble and expense for an office as it is for a bedroom.


What can Eurobuilt window systems do to give buildings a new lease on life?
A lot. Fitting Eurobuilt windows enhances the living comfort and thus the market value of your house or building. Renovation enhances construction physics performance values, in addition to "face-lifting" a building and allowing for value-enhancing improvements.


What colors are Eurobuilt window profiles available in?

White window profiles are the most popular. This is in keeping with a European tradition going back hundreds of years. It also permits the advantages offered by the profile material to be utilized to full advantage. However, Eurobuilt also offers attractive imitation wood patterns and many color-coated profiles.


How much maintenance and care do Eurobuilt windows require?
"Easy care" describes Eurobuilt windows best. Dry, wet, or aggressive dirt doesn't adhere to Eurobuilt's perfected, silky smooth finish like it does to a cracked, porous finish. Normally only a mild detergent is required.


How can windows be made burglar-proof?
High-strength profiles offer the best solution. Special fittings and glazing, qualified window fabrication, and expert installation make the window worthy of being termed "burglar-proof".


How do Eurobuilt window systems behave in a fire?
Eurobuilt window systems offer considerable fire protection. Our profiles contain a flame retardant that does not decompose with time. It will not burn by itself and extinguishes itself without providing an ignition source.


What are the profile designations of a window unit? And what are various parts called?

  1. frame profile

  2. sash frame

  3. transom with decorative profile

  4. add-on-profile

  5. Georgian bars

  6. weather bar

  7. sash

  8. fanlight sash


Which opening variations can a window have?

  1. turn sash

  2. tilt sash

  3. tilt and turn sash

  4. sliding sash

  5. folding sash

  6. horizontal pivot sash

  7. vertical pivot sash

  8. top-hung sash


What sort of window segmentation is best?

The decisive factors here are the architecture of the façade and the layout of purpose of the room. Thanks to the great variety offered by Eurobuilt window systems, a window area can be virtually subdivided in any manner desired. However, excessively wide sashes should be avoided, as they protrude far into the room when open, thus turning entire room areas into "non-usable" space.


Are sliding doors possible?

Yes. And sliding windows made of the same ultra-slim profiles. Large windows or terrace doors facing the south and pretty views make large-area glazing attractive. In addition to enlarging a building's living space. In winter, incoming sunlight can contribute considerably to reducing heating costs.


Does Eurobuilt make all-in-one window roller shutter units?

Yes, a popular item for both old and new buildings. In renovation projects, it allows rolling shutters to be integrated in places heretofore not possible. When rolled down, a rolling shutter provides for substantially improved heat insulation and a cosy atmosphere inside the room.


Can an intact wood frame be reused in renovation?

Yes, by using Eurobuilt's universal system. The wood frame already present needn't be removed. On the contrary, it is "capped over" on the inside and outside with Eurobuilt's system, which was specially developed for this purpose. The frame can accommodate the various sashes and transoms made of Eurobuilt profiles.


Does Eurobuilt make shutter profiles?

Systems are also available from Eurobuilt offering convenience coupled with marked design freedom. They offer good value for money thanks to Eurobuilt's cost-effective manufacturing operations. Various shades and wood finishes are available. Classical shutter types with sloping (also adjustable) slats are available as well.


Does Eurobuilt make conservatories?

Yes, not just merely creating "greenhouses", but transforming these areas into fully-fledged rooms which can also be used in winter. Insulating glass panes measuring up to 30mm thick can be used. Ideal connecting profiles are available for joining the structure to the house or building. Roof windows can easily be integrated. The modular design provides for lower costs coupled with optimal design freedom.


What does a qualified window fabricator offer me?

Whether the project you have in mind involved renovating an old building or constructing a new one, he is the expert that you should consult during the planning stage. He will meet with you personally to determine the most optimal and economical solution just for you, properly taking into account the intended purpose and desired sound and thermal insulation. He can show you other comparable finished windows and submit a cost estimate at no obligation to you. If you do decide in favor of him, he takes exacting measurements, fabricates the windows, and installs them in an expert and timely manner. Supplementary work like plaster patching can be offered as well. He shows you how to operate your new windows and is the person to contact for customer service.


How long does it take to replace old windows?

Generally this can be done in a matter of hours, or a few days if many windows are replaced. When delivered, the new windows are completely glazed. The old window is carefully removed, the new window is inserted and fitted with millimeter precision, tied in place, and sealed.
