Glass might be transparent but it makes up a significant part of every window. When buying new windows, many focus on the style and frame colour without considering how important the type of glass is. You might think that glass is just glass, but, not all glass is the same. Glass comes in varying thicknesses, clarity levels and coatings, all imperceptible to the human eye, but choosing the right glass can improve your home's energy efficiency, security and noise reduction.
There are several types of glass you can choose for your windows and doors depending on the needs and problems in your home. Whether it's energy efficiency, reducing external noise or protecting furniture from UV damage we have the right glass to solve the problem.
A double glazed window has 2 panes of glass and 4 faces whilst a triple glazed window has 3 panes and 6 faces. In an individual window unit, different types of glass can be used and by combining these, we can create specific windows and doors to meet different needs.
If different problems in different rooms are an issue, the right specialist glass unit for each room will make a significant difference. By selecting the right type of glass for each room, you can optimise to ensure maximum comfort, security and energy efficiency in your home. Don't feel you have to have a house full of the same glazing.
With a market-leading BRFC energy rating, this range uses a combination of Low Iron glass to allow the sun’s heat to enter, and Low Emissivity glass to keep the heat inside, helping to reduce your energy bills. Both double and triple glazing are available with a security laminated option.
Helps reduce the amount of noise disturbance that can enter through a window. A special acoustic laminate is added to the glass to help dampen sound waves, plus the air gap between the panes helps achieve a quieter home. The laminate provides security benefits, as well as additional protection from UV damage.
Our new range achieves our lowest U Value with the glass acting as an insulator. The high-performance solar reduction glass reflects the sun's rays whilst noticeably reducing heat loss. The glass is toughened as standard and both double and triple glazing are available with a security laminated option.
