With its triple pane construction and argon gas filling, GAYKO High-Tech thermal insulating glazing achieves an outstanding Ug value of 0.5 W/(m2K)

Window glazing has been continually developed and improved in the last 40 years. Until late in the 70s, windows were mainly built with single glazing (> 6.0 W/(m2K)). Later, up to about 1994, the old insulating glass (double-glazing pane) with Ug values of 3.0 W/(m2K) was used. The calculations in the Energy Saving Ordinance included window insulation values for the first time in 1994. As regards energy and technology, windows made before 1995 are therefore long out of date and replacing them should be regarded as imperative. The standard today is thermal insulation glass with a double-pane construction. The good insulating properties here come from a filling of inert gas and a thin invisible coating.

 

GAYKO already offers you very good high-tech insulated glazing with a Ug value of 1.1 W/(m²K) in the standard version. With Gayko High-Tech Thermal Insulating Glass you get the best values of all: The triple pane argon gas-filled construction achieves the outstanding Ug value of 0.5 W/(m2K), which makes it suitable even for passive houses. For this glazing, because of the greater installation depth, the window type GAYKO PASSIV is suitable.

In windows intended to provide optimal thermal insulation, the glazing plays an important role. U values (thermal transmission coefficients) can be used to quantify rates of energy loss. The Ug value supplies information about the amount of heat conducted through a pane of glass (the "g" in Ug is for "glass").

Saving energy with large windows

Large window areas provide brightness, make life more pleasant and make your rooms appear generous and friendly. But not only that: You benefit with highly insulating GAYKO large-area windows (especially if your windows face south) from the large amount of light and heat supplied free by the sun, but also gain protection from excessive heat. For example, GAYKO windows with super-thermal insulating glazing with Ug values as low as 0.5 W/(m2K) let more heat in than escapes out in winter, when the sun is low in the sky. The positive energy balance considerably reduces the energy consumption of your heating.

You achieve the best possible U values with GAYKO's highly insulating glazing and leading technology in the window frame and casement such as GAYKOTGS and "warm edge" and competent installation of the windows. With this GAYKO ensures high strength and resistance to loosening despite heavy panes, through the use of the patented GAYKOESP technology (extremely stable profile fastening).

Did you know: that all windows manufactured before 1995 are ENERGY GOBBLERS?
