Glazing units are very important part of windows and doors. Window characteristics depends on the glazing method. Glass units make up a large area of the product, so most of the heat can be lost through the window glazing unit, but also it can be gained through the glass as well. For this reason, the thermal insulation of a window largely depends on its glazing. Glazing units also determine window sound insulation level.

Highest-quality, heat-saving MEGRAME® glazing units are used for glazing windows, doors and aluminum constructions. MEGRAME® glazing units are produced using GUARDIAN, EUROGLAS, SAINT-GOBAIN and other premium glass that improves comfort and reduce energy costs. Glazing units are manufactured from polished M1 class FLOA glass, which is made by pouring molten glass on melted tin. This leads to the highest-quality, flatness, smoothness and uniform thickness of the glass.

MEGRAME® glazing units are made with Low-E (Low-Emissivity) spectrally-selective glass. Low-E glass is covered with a special coating that retains and does not release heat from the room and thus greatly improves the insulating characteristics. Low-E glass is produced by coating the glass with a metal oxide, which reflects from 40% to 70% of the heat and this way, the heat returns to the room. The heat transfer coefficient U of glass units ranges from 0.5 W/m2K to 1.7 W/m2K.
