What is Double Glazing?

Double glazing has ended up being a familiar sight in the majority of houses across the UK due to its many advantages. Cutting energy bills and decreasing sound pollution are a few of the lots of factors that double glazing has become a popular option for consumers. However, do you know what double glazing is and how it works?

What is double glazing?

The gas filled space in between the panes of glass is the main factor for the decrease of heat transfer from a building, leading to a more energy efficient window. The two panes of glass will be separated by a spacer bar and sealed in place developing an airtight system.

Where did double glazing develop from?

Double hung and storm windows are an older kind of glazing where double glazing is stated to have actually progressed from. This older form of innovation included a single pane of glass separating interior and exterior areas. To keep insects and animals out in the summer season, a window screen would be hung, with a storm window being added in winter season to create a double layered impact for insulation.

Kinds of glazing

Double glazing can be obtained utilizing many different types of glass. Safety glass is among the more important kinds of glass and is necessary in many structure types including schools and roofing system windows to prevent injury. There are also locations around the house, referred to as important areas where shatterproof glass must be used. Doors and panels surrounding to doors within 1.5 m from flooring level in addition to low level glazing such as windows that are within 0.8 m from flooring level must be glazed in security glass .

Laminated glass is a kind of safety glass which is more powerful and more durable than basic glass. It is constructed of two sheets of glass surrounding a plastic interlay sandwiched in between. This manufacturing process produces a pane of glass that, if broken, would continue to stick to the interior plastic layer minimizing the danger of injury.

Five times stronger than standard glass, tempered glass is a kind of safety glass which includes additional security and safety when utilized in specific areas. Tempered glass is subjected to intense heat followed by being rapidly cooled during its production procedure to produce its strength. To trigger less injury, tempered glass is produced to shatter into hundreds of tiny pieces if broken.

How does double glazing help in reducing heat loss?

The gas caught between the two panes of glass in a double glazed window is key to the insulating homes that it produces. The gas generally utilized to develop this insulation is Argon, which utilizes around 65% of the thermal conductivity of air, resulting in it being extremely inefficient at carrying out heat trapping it inside the residential or commercial property. Energy performance of the residential or commercial property is also increased by the spacer bar utilized in the constraint of the system. Our spacer bar for instance, is 1000 times more energy effective than basic aluminium, contributing to the energy effectiveness of the window and minimizing heat loss in the property.

This scale ranges between 0 and 1 and suggests just how much heat is let in by the window.

Air Leak is the last element to consider. Shown by the L worth, air leak happens if there is a weakness in the glazing unit. A lot of contemporary window systems are air tight and must therefore have an L value of absolutely no.

What types of double glazing frames are available?

Unplasticized polyvinyl chloride or uPVC, is the most popular type of window frame used for double glazing With white being the most desirable, a range of colours are readily available in uPVC doors and window frames. Being anywhere approximately 3 times more affordable than wood frames, other advantages of uPVC consist of energy performance, durability and recyclability.
