Double Glazed Units
Our double glazed units are expertly manufactured to provide outstanding thermal efficiency. Ideal for both residential and commercial applications, they are designed to meet the highest standards for performance and longevity.

Why Double Glazing?
Choosing double glazing for your home or building project is a smart investment that offers a range of practical and long-term benefits.
This type of glazing is made up of two panes of glass with a gap in between, which acts as an insulating barrier to reduce heat loss.
Double glazing helps to ensure your home stays warmer in the winter and cooler in the summer, helping to lower energy bills and reduce your carbon footprint.
Double glazed windows are significantly more resistant to breakage than single glazed options, offering greater strength and enhanced security.
Enhancing Efficiency
Our double glazed units are designed to significantly enhance energy efficiency by reducing heat loss and minimising drafts. The two panes of glass are separated by a gas-filled cavity, which acts as an insulating barrier, contributing to a more comfortable indoor environment and a reduced carbon footprint.

Double glazing can help reduce condensation, but it doesn't completely stop it. By creating an insulating barrier between the inside and outside temperatures, double glazing keeps the inner pane warmer, which makes condensation less likely to form. However, condensation can still occur if there’s excess moisture in the air and poor ventilation, especially on the outside or between the panes if the seal is broken.
Double glazed windows reduce heat loss by using two panes of glass separated by a gap filled with inert gas. This gap acts as an insulating barrier, slowing down the transfer of heat between the inside and outside of a building. The inner pane keeps warm air in, while the outer pane helps block cold air from entering. This insulation effect significantly improves energy efficiency by keeping indoor spaces warmer in winter and cooler in summer.
The cost of double-glazed windows can vary depending on the manufacturer and size. Here at UKO Glass, we offer the best value for money on our double glazed units. We work closely with a range of window manufacturers across the UK as their main glass supplier.
Double glazing refers to a type of window construction that features two layers of glass with a gap between them, typically filled with gas for insulation. This design helps to reduce heat loss and improve energy efficiency. It's commonly used in residential and commercial buildings to enhance comfort and reduce energy bills.
