Products > Secondary Glazing
Secondary glazing units fit to the inside of the prime window, leaving the original window in place. Manufactured in polyester powder coated aluminium sections in any RAL colour, secondary is an efficient and cost-effective way to eliminate draughts, increase thermal insulation, improve the security of prime windows and reduce noise.
Various formats are available - horizontal sliders, vertical sliders, hinged or lift-out models.
Horizontal sliders generally fit inside casements or doors and are available in two, three, four or five panelled versions, with sashes fitted on brass rollers to ensure smoothest sliding action.
Vertical sliders are ideal for providing a secondary barrier inside original box sash windows. They are hung on pre-tensioned spiral springs with tilt-in facility for ease of cleaning and fire escape.
Hinged units open into the room and may be hung on friction hinges or, alternatively, butt hinges. Lift out units... well, they simply lift out.
