We care about quality.

As we all increasingly value and use our gardens and outdoor spaces, having patio doors has become an essential design element in homes and properties around the country.

We offer three types of doors and each type comes in many different styles. You can choose from timber-framed or aluminium-framed products and all doors can be customised to your own individual preferences.

You choose the type.

In terms of functionality, doors can be divided into

  • French doors
  • Bi-fold doors
  • Sliding doors

and details of these products can be viewed by clicking on the links above.

All Lemon Glass patio doors offer secure locking mechanisms, safety glazing and a range of finishes as standard options.
