Frame shapes with more regular lines make these windows suitable for modern houses. Not only do they look impressive, but they also provide excellent warmth. All thanks to the 3-pane sealed unit with low-emission glass and argon-filled inter-pane void. Tightness is ensured by a system of three gaskets - two grooving gaskets and one edge gasket. Increased thermal insulation is achieved through deeper installation of the sealed unit in a wooden frame.
