Panes in our windows are adapted to the customer’s individual needs in terms of:
- thermal insulation,
- acoustic insulation,
- protection from injury,
- protection from burglary,
- sunlight protection,
Thermal insulation panes
The currently produced thermal insulation panes reach an average value of heat transfer coefficient k = 1,0 W/m²K and the latest 3-pane units reach the value of k = 0,5 W/m²K which limits heat losses to a large extent and allows for better use of solar energy. Even using the panes with the first value shall bring about measurable heat cost savings.
A thermal insulation pane is composed of a set of two 4 mm glass panes with 16 mm gap between them. There is an aluminium frame between the panes featuring the name of the pane and the heat transfer coefficient (k). Thermal insulation panes protect heat by an invisible layer of metal oxides on the internal pane and filling the space between the panes with gas.
A standard window reduces noise at the level around 32 dB. A sound-absorbing window is effective in absorbing up to 52 dB noise. This is possible due to manufacturing thicker glass units made of paned with various thickness, increasing the gap between the panes and filling it with heavy gas.
Sound-absorbing panes are characterised by heat transfer coefficient k=1,0 W/m²K, so they provide excellent heat insulation in addition to the sound-absorbing properties.
They combine excellent thermal insulation (heat transfer coefficient k=1,0 W/m²K) with protection in case of breaking. They also protect from unwanted interference from the outside.
They are available in two variants:
- single-layer security panes (ESG) – toughened glass – when the pane is broken, it breaks into small pieces of glass with blunt edges (used for sport venues and areas where children stay),
- multiple glazing (VSG) – laminated glass – a pane laminated of two or more layers of glass combined in one unit with tear-proof foil. When you hit it, the glass does break, but the parts of it remain on undamaged foil in the frame. Thickness of such panes is 3.5 mm to 39 mm (used in, among others, public utility buildings as well as buildings prone to burglary or vandalism such as kiosks, shop windows, etc.).
