Much like our French doors, patio doors from Emerald are capable of incorporating energy efficient glazing to offer excellent levels of thermal retention, which in turn can have a positive impact on your energy bills.

All this is achieved alongside an effortless sliding mechanism that makes efficient use of space so that they are extremely easy to operate. Simply slide them to one side and move easily between areas of your home and when they’re not in use, enjoy a stylish looking set of doors that provide visual enhancement to any properties that they’re fitted upon.
