Benefits of Low E double and triple glazing?

  • Warmer home in winter - Low E glass gives your home up to twice as much heat retention as standard double glazing, keeping the heat inside and the cold outside.

  • A cooler house in summer when you choose a Low E glass with solar control, it helps reduce heat gain from the sun, that can overheat your house, while also insulating your house from the temperature outside in winter. And because there is less need for cooling systems, you'll be reducing energy consumption, which saves on your power bills and helps the environment.

  • Lower power bills - because there is less need for heating and cooling power use, you'll be reducing energy consumption, which saves on your power bills and helps the environment.

  • Reduced condensation. Condensation is that “crying look” that single glazed windows get. This is a serious problem, it causes mould and mildew, and damage your family's health.

  • Better resale value of your home. Having a more thermally efficient home, will improve the feel of the home and reduce its energy usage.
