During long, sunny summers, homes with large glazed areas can heat up like a greenhouse. We explain how solar control glass works, the concepts of g-value and light transmittance, and how to choose the right glass for each facade orientation.
Most windows whose handle is stiff, whose sash rubs on the frame or that let in draughts when closed can be fixed with a simple adjustment. We explain how to identify the cause from the symptoms and when parts need replacing.
