Window KLI Classic E 68 has profiles with thickness of 68 mm from three-layered glued lamellas non-bounding by length and has the same appearance as the window KLI Classic 68. The difference lies inside the construction of window profile, which contains air channels. The air channels within the window profile improve the heat isolation. This can improve the heat insulation for up to 30 % in comparison with ordinary window profiles.

You can choose among numerous tree species (pine, larch, meranti, oak …), which vary in their outlook and mechanical properties.

Window KLI Classic E68 is especially convenient for installation in energy saving buildings due to its improved profile characteristics. It is also suitable for renovations, if we wish to increase the value of a building and improve the quality of living.
