Insulating glass
The main functions of a window are to protect the building and its occupants from the influence of external factors (too low or high temperatures, noise, etc.) and to ensure natural lighting. Therefore, one of the most important elements in the equation of the quality of a window is the glass.

Winter Comfort
The insulating glazing blocks the heat already present in the room while still allowing natural sunlight and warmth to pass through the glass, helping to heat the interior during the cold season.

Energy Efficiency
Thanks to the airtight glazing system, heat is retained indoors during winter, while solar radiation is reflected in summer. As a result, both heating and air conditioning costs are significantly reduced.

Summer Comfort
The glazing reflects two-thirds of solar radiation while still allowing natural light to enter the interior. This ensures a comfortable indoor temperature without sacrificing natural illumination.

Transparency
Natural light is essential for comfort. We use glass with a high degree of transparency, ensuring excellent light transmission and reduced artificial lighting costs.

Safety
Glass lamination is an effective method of protection against accidents. In the event of breakage, the shards remain attached to the plastic film (PVB) inserted between the glass panes.

Security
For enhanced protection of both property and people inside, we recommend laminated safety glass, consisting of two PVB plastic interlayers placed between two glass panes.

Acoustic Comfort
Acoustic glazing blocks unwanted external noise, transforming the home into a calm and comfortable living space. These glazing units contain a special plastic interlayer that prevents sound from propagating from one glass pane to another.

Are available in several colors and can be easily matched to the house’s joinery. The aesthetic function of highlighting and defining the window combines with the functional one of protecting the wall. They are quick to install and, thanks to the laminated outer surface, are easy to maintain, resistant to moisture and scratches.
Exterior sills
Aluminum sills are used to protect masonry from rainwater infiltration. They contribute to a significant improvement in water tightness and are a less expensive solution than sills made of granite or marble. Exterior sills are resistant to UV rays and give your home an aesthetic addition.
