Window Styles & Colors

Quality windows and doors don't have to come with a high price tag. Vinyl is an excellent frame material with a fantastic price-performance ratio. Moreover, it is available in hundreds of colors to match your needs and home's exterior. Each of the over 200 colors in the RAL Classic range have a unique code to make choosing and ordering simple.

Popular RAL colors include:

RAL-Code Color
7016 Anthracite gray
3018 Strawberry
6025 Fern green
5003 Saphire blue

Unlike wood and aluminum, vinyl windows are given special colored foil finishes that are directly applied to the sash and frame by the manufacturer. This foil also protects the surface from weather, scratches and other wear.

The additional layer of protection from this type of finish makes them even easier to care for and helps ensure a great appearance for many years to come.

Glazing & Insulation

Energy efficiency has become increasingly important over the past several years. Windows and exterior doors are major sources of both potential energy loss, but also savings.The Energeto series, for example, is aimed at those requiring higher insulation values.

In addition to the profile type and number of chambers, the glazing selected can make all the difference between an energy efficient home and one that wastes energy and needlessly increases your costs.

Insulating glazing is therefore a popular option for homeowners. There are several types with a range of heat transmission coefficients (U-value):

  • Double glazing with 1.1 W/(m2K)
  • Double glazing with 1.0 W/(m2K)
  • Triple glazing with 0.7 W/(m2K)
  • Triple glazing with 0.6 W/(m2K)

The heat transmission coefficient indicates how much energy that a particular element of a building – in this case the window – loses per square meter, when the temperature difference on the interior and exterior is one Kelvin. The lower the value, the better. Considering the number of windows in a home and their combined surface area, a difference as low as 0.1 W/(m2K) can mean a huge difference in a home's energy efficiency after installation and therefore your monthly bills.
