What Is Double Glazed Windows?

Insulating glass consists of two or more glass window panes separated by a vacuum or gas-filled space to reduce heat transfer across a part of the building envelope.

What are the benefits of double glazed windows?

The air gap is filled with gas which increases the insulation between the glass pieces. Double glazed windows are highly efficient, reducing your heat loss or gain by up to 30% when compared to single-glazed windows. Double glazing works much like woollen clothing and fibreglass batts.

Is double glazed windows worth it?

Most of the energy consumption can be avoided with low U-value windows, as heat loss from inside to outside is minimised. Double glazing can help reduce heating costs significantly, especially in combination with low-e glazing and gas cavities, stabilising inside temperatures and keeping loss to a minimum.
