Spacer frame is a key component of an insulating glass unit, responsible for maintaining a precise distance between glass panes and ensuring the tightness of the entire chamber filled with noble gas. Although visually it appears as only a subtle frame of the glazing, its parameters determine whether the window edge remains free from freezing and water vapor condensation. At All Windows Group, we use advanced composite and aluminum systems that stabilize the structure of the unit and significantly improve the thermal insulation performance of the entire joinery, eliminating the formation of linear thermal bridges. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
