What Benefits Do Double Glazed Units Offer?

What Drawbacks Come with Double Glazing?

The Function of Double Glazing

Two layers of glass make up double-glazed units, which act as a barrier to lessen heat loss and outside noise. The space between the layers is typically 9 to 12 mm wide and is created by a spacer bar. The air that is trapped between the panes doesn’t have enough room to circulate and acts as an insulator, slowing the flow of heat. Convection is the phenomenon that gives double glazing its insulating qualities.

The units can additionally be coloured, translucent, or covered in reflective film. The two latter choices are helpful for limiting the amount of UV light that can enter your home.

Double glazed unit components

The following six elements make up double-glazed products:

    • Glass
    • A frame that divides the two glass panels is known as a spacer bar.
      primary seal: the primary impediment to airflow
    • The secondary seal is the glue holding everything together.
    • Cavity: the space separating two objects
    • a silicon substance between the panes known as a desiccant that absorbs moisture
    • Gas: krypton, argon, dehydrated air, or xenon

What Kinds of Double Glazed Units Are There?

Many businesses now provide a variety of materials and glass options so that you can tailor the windows and doors to your needs. There are several frame, glass, shape, and spacer bar options available.

Kinds of Frames 

    • uPVC: Unplasticized polyvinyl chloride frames are the most common option among UK homeowners among the many frame types. They come in a variety of colours and are the least expensive alternative. Finding a supplier who gives at least a 10-year warranty is advised because the sole drawback of uPVC frames is that they may expand under intense sunshine.
    • Timber: Wooden frames are the most insulating and long-lasting material, despite being the most expensive and requiring the most upkeep. Timber frames will also give your house a more classic appearance.
    • Aluminum: Due to their inferior insulation properties compared to uPVC and timber double-glazed frames, these frames are the least preferred option. However, other people favour aluminium framing because of its contemporary looks, ease of upkeep, and durability.

Various Glasses

    • Low-emissivity (low-e) glass: As one of the most common choices, low-e glass greatly increases the energy efficiency of double-glazed units. It is advised for homes in chilly climates that demand a lot of heating. Additionally, it lessens the quantity of dangerous UV radiation that enters the glass.
    • Safety and security glass: There are many different types of safety and security glass that are less likely to break or represent a threat when damaged, protecting your home from burglary, vandalism, and any form of transgression. Laminated glass, toughened (tempered) glass, wire mesh glass, and etched glass are some of the most popular designs.
    • Tinted glass: By adding a film to double-glazed glass, tinted windows and doors can cut down on UV light transmission, shield your furnishings from the sun, and keep your home cooler in the summer.
    • Reflective glass provides your house a more contemporary appearance thanks to its shiny surface. The reflective layer lessens the amount of heat and sunlight entering the room.
    • Stained or coloured glass is a popular option that many businesses provide, allowing you to customise the double-glazed units to your specifications.
    • Acoustic glass is a fantastic solution for people who live in crowded, noisy areas of the city. An additional acoustic interlayer that softens the sound waves coming from the outside provides the additional noise reduction.
    • Decorative glass is available from a number of double-glazing manufacturers in a variety of patterns, textures, and opacities. Some of the aforementioned varieties can be paired with decorative glass to give your home a distinctive appearance.
    • Self-cleaning: Modern uPVC windows are also available that do not need to be cleaned. They have a clear pre-coating that disintegrates dust and debris.
