FENSA is a government-authorised scheme that monitors Building Regulations compliance for replacement windows and doors in England and Wales. A FENSA Approved Installer can self-certify eligible replacement window and door installations and register the work with the local authority. Andrews Glass is FENSA Approved, so qualifying installations can receive a FENSA certificate confirming that the work complies with the relevant Building Regulations.

Double glazing uses two panes of glass within a sealed unit, while triple glazing uses three. Triple glazing can provide greater thermal insulation, while modern double glazing already offers strong energy efficiency for many homes. The best option depends on the property, window specification, budget and level of thermal performance required. Andrews Glass supplies and installs both double and triple glazing and can advise which is most suitable for your home.

Secondary glazing adds a separate glazed panel inside an existing window, while replacement double glazing replaces the existing glazing or window with a new sealed double-glazed system. Secondary glazing can be useful where retaining the existing windows is important, whereas replacement windows provide a more complete upgrade to the window itself. Andrews Glass supplies both secondary glazing and replacement double glazing.

uPVC and aluminium are two different window frame materials with different characteristics. uPVC windows are durable, low-maintenance and cost-effective, while aluminium windows use strong, slim frames that suit contemporary designs and larger areas of glass. Andrews Glass supplies and installs both uPVC and aluminium windows, allowing the frame material, glazing and style to be chosen around your property and priorities.

Acoustic glass is specialist glazing designed to reduce the amount of external sound passing through a window or glazed area. It uses a different glass construction to standard glazing to improve sound insulation and can be particularly useful for homes affected by road, rail or other environmental noise. Andrews Glass supplies acoustic glazing solutions for properties across Hertfordshire and surrounding areas.

Window and door repairs can address problems such as damaged components, difficult operation, draughts and other faults where complete replacement is not necessary.
