News Discuss 
Double Glazed windows are made by having two panes of glass separated by way of a spacer bar, these panes are sealed around the outside edges with the glass to form a sealed unit, this device is often pumped with argon gas and these windows let significantly less heat through http://test.dragonstar.ru/user/tcbqyhfy38/
