By trapping air between two panes of glass, the air acts as insulation, making it harder for noise, heat and condensation to travel through.
Whilst normal window glass is between 5mm - 8mm thick, our windows are fitted with 19mm - 28mm glass units making your windows more energy efficient.
Although initial costs for installing double glazed windows are higher, in the long run there are increased cost savings from air conditioning efficiency. The return on investment is usually within 4-5 years.
