There are a few key moments when changing the window frames. We will try to explain these in a most straightforward way in order to facilitate you when choosing new window frames that will last for decades.

Budget
First you have to determine a budget so that you know what you can afford. PVC windows and doors are the most affordable. This doesn’t mean that they are of low quality. It is just that they are made of plastic and are less durable compared to wooden or aluminum window frames.

Glazing
Next, it is very important to choose the best glazing for you. The glazing makes up for 80 % of the area of the windows- actually, it is even more important than the profile of the window frame. According to european standards the window frame should have minimum double glazing (2 glasses) with one being a low-emission glass (Ka glass) and the other- white float glass. This type of glazing has quite sufficient insulation characteristics.  For even better insulation a combination of multifunctional and white float glass is used.

Noise protection
For the best noise protection we again turn to glazing. The best protection is made of a glazing combination of triplex glass and white float glass. Even higher standards of noise protection are achieved when we use triple glazing (3 glasses).

Security
We achieve the highest degree of safety and security when using glazing with triplex type glass. It is highly durable and doesn’t break but only cracks.

Fittings
Windows open with the aid of the fittings of the window frame. The fittings are supremely important for each window or door that opens. We trust only quality german fittings so that you feel safe when you order new windows for your home or factory in our company.

Colors
The standard color is white. This is not only because the white windows are the most affordable in terms of price. The white color is the most durable since it is not affected by the sunrays in the same way as window frames with dark colours. The white window frames are the most popular ones not only in Bulgaria but also in Austria, Belgium, Germany, France, Italy and more. However, another quite popular color is the wood imitation: golden oak, walnut, dark oak or wenge. These are very beautiful shades that naturally complete the facade.  

Types of window frames
We offer several types of window frames- wooden, PVC, aluminum. We hope that we have been quite thorough in order to help you in choosing the best type for you.

Why window frames from G-fenster?
G-fenster is a part of GSG. We have over 20 years of experiencе in the sphere of windows and doors. You can trust our experience when deciding to change your windows. 

Advice and recommendations
If you have limited funds we recommend that you choose economy class of window frames but a one that has well-insulated glazing.The glazing accounts for the largest portion of a window and the investment in such is worth it in a long–term perspective. The money saved from electricity will compensate for the difference in price really quickly.

Aluminium window frames  

The advantages of aluminum make it applicable almost everywhere. It is relatively resistant to corrosion. It is light, yet durable. The aluminum frame is not damaged when there are substantial differences in temperature and it preserves its structure. It is ductile which allows your frames to be manufactured in different shapes. Delivering modern design is easy using aluminum frames.

The standard color for the aluminum profiles is white. However, your windows can be powder-coated with RAL colors of your choice. We also offer various decorations on painted surfaces.

Aluminum frames are affordable, easy to maintain and long-lasting.
Aluminum frames are heat-resistant, they do not distort and deform due to atmospheric conditions.

We also offer aluminum profiles with thermal break /worm profile/ with which a higher coefficient of thermal insulation is achieved.

Wooden window frames  

NATURAL MATERIALS, HIGH QUALITY WOOD

Profiles
Wood is increasingly used in various industries. It is a natural raw material and does not harm the environment. It can be easily processed and thus achieve a variety of classic and modern architectural solutions..

The wooden frames create a cozy and warm feeling in your home.
The advantages of the wooden window frames are natural. Wood has the unique quality of absorbing and conveying moisture. 
Bulgaria is situated within the humid continental climate zone which makes wooden window frames really suitable for these atmospheric conditions. In addition, the wooden windows achieve excellent thermal insulation, sound insulation, high stability, a variety of shapes.

We produce wooden windows using modern technology. The quality of the material we use is guaranteed by our german partner Münchinger - one of the leading suppliers of high quality timber. We manufacture different wooden window frames using spruce, oak, shorea, mahogany. The wood has been processed several times in order to ensure a stable, high quality and durable profile. We use paints and water-based varnishes with UV protection. The quality, density and durability of the colors is guaranteed by our partner Remmers that offers a wide variety of colors depending on your wishes and taking into consideration the interior of your home.

DESIGN AND CLEAN LINES, A STYLISH ADDITION TO YOUR INTERIOR
Stylish rounded wooden frames profile that doesn’t require a lot of maintenance and is easy to clean. The wooden frames are a perfect addition to the interior of the house and they contribute to the feeling of coziness.

UNCOMPROMISING COATING QUALITY

    
Varnishes
Can be easily combined with the design and furniture of the room. Wooden window frames varnishes are available in a wide variety of colors - covering or azure. There are solutions even for non-standard situations. In some buildings, the facade is unique. However, the interior does not need to match the facade. For this reason we offer two-color wooden joinery - different colors on each side. This is possible even for small projects - a house or an apartment. With the other types of window frames this is possible only for large projects since the coating of the profiles is done in advance, unlike the wooden joinery.

GERMAN QUALITY MECHANISMS FOR OPENING WINDOWS - MANUFACTURED IN GERMANY

  
Fitting
The fitting of the wooden window frames and doors is of supreme importance. For this reason we trust the highest class in Europe - the Roto brand. The high quality fittings have many advantages. The most important one is that with it the wooden joinery functions seamlessly even after 10 years. The german fitting of the wooden frames is adjustable, so in case of sagging it can be easily adjusted. Not to ignore the possibility of adding a lot of extras with almost no difference in price.

Micro Ventilation
One of these extras is micro ventilation. It allows ventilation without opening the windows. This also increases the burglary protection. The additional cost when supplementing microventillation is minimal since Roto fitting has taken this into consideration and the only thing necessary to add is a metal plate and a special handle.

SECURITY IS OF PRIOR IMPORTANCE - WINDOWS ARE ONE OF THE FRAGILE POINTS

    
The wooden joinery is equipped with a basic security level by standard. It can easily be upgraded to a higher level of security, which makes breaking into the house extremely difficult and slow. Statistics show that quite often thieves enter through windows, so it is very important that high-risk locations are well-protected. In order to increase the security of the wooden windows it is important to configure the windows with the right glazing - with tempered glass or triplex.

PROFILE STRENGTH IS GUARANTEED BY JOINING SEPARATE LAMELLAE TOGETHER

  
The wooden window frames and doors manufactured by us have been assembled by triple/quadruple-sealed profiles from solid wood. The individual layers of the wooden joinery profile have opposing wood circles to eliminate the risk of distortion.

WOODEN JOINERY IS A GREAT CHOICE FOR YOUR HOME

Wood is a natural material, the wooden frames have deep traditions, and have been advancing for a long time. The material is porous and the profiles are solid. The wooden frames offer considerable insulation and many optional different shapes.

PVC window frames  

PVC joinery materials - made with nature in mind
The technology for the production of PVC profiles is highly advanced nowadays. As a result, PVC window profiles are of high quality. They are manufactured using recyclable materials - so pollution of the environment is very limited to almost no negative effect. With its multi-chamber PVC structure, the windows achieve good thermal and noise insulation.

For the production of PVC window frames we use the profile Trocal - from the leading German manufacturer Profine. Alternatively, we also offer window frames from the Bulgarian Vivaplast profiles, which combine high quality and good price.

Design of windows with straight lines and smooth curves
Our PVC window frames have a beautiful and clean design, with delicate shapes and smooth curves. PVC window frames are easy for maintenance and do not need to be treated with special cleaners.

A variety of colors that beautifully complement the interior

 
The standard color for the PVC frames is white – a color that can easily blend with the interior around the windows. Recently, anthracite grey came to be a very modern and desired color. Last but not least are the different options for wooden decorations and wood imitation.

Fittings as a factor in windows security

 
The windows are a fragile point for burglary protection. Therefore, it is a good idea to pay attention to their security. Our window frames are equipped with a basic security level by standard. Upon customer request the configuration can be upgraded. For PVC window frames, we only use fittings from a German manufacturer - Wink Haus and Siegenia. Each of our fittings has an anti-corrosion coating.

Profile durability and strength

 
A minimum 1.5 mm reinforcing steel profile is fixed in each profile. The European production standards are high, so is the quality of our PVC window frames. The PVC window frames are also protected from distortion.

Different types of PVC profiles

70mm profile 76mm profile 85mm profile

The PVC window frames are mainly distinguished by the number of chambers and the thickness of profile. The standard 76mm profile has 5 chambers. The high class 85mm profile has 6 chambers.

What makes PVC window frames so desired

  
The PVC window frames are easier and faster to make. They are very affordable compared to wooden or high quality aluminum ones. The technology for the production of PVC profiles is highly advanced nowadays. Therefore, PVC window frames offer perfect value for money.

Color
The standard color of aluminum joinery is white on the inside and gray on the outside. Wood + aluminum allow the greatest color individualization. Both materials can be processed in virtually any desired color - even for small volumes. The wood profile varnish is water-based by REMMERS GERMANY and the aluminum one is powder coating.

Durability and strength
The wooden joinery with aluminum outside covering is very solid and stable. The wooden profiles are made of joint layers of wood. Aluminum profiles are also very stable due to their thickness and structural reinforcement. Thermal bridges are prevented by the special way of installing aluminum profiles to the wood.
