• How do I decide what type of glass to use? Deciding what type of glass to use can be a challenging task, as there are many different factors to consider. One of the most important things to consider is the location where the glass will be installed. Different types of glass are better suited to different locations and uses, so it's important to provide your glass supplier with as much information as possible about the intended use of the glass.

    For example, if the glass will be installed in a high-traffic area, you may want to choose a type of glass that is more durable and less likely to be damaged by impact. On the other hand, if the glass will be used in a location that receives a lot of direct sunlight, you may want to choose a type of glass that is designed to reduce heat gain and glare.

    Another important factor to consider is the history of the area where the glass will be installed. If the glass has been vandalized in the past, or if there is a high risk of vandalism in the future, you may want to choose a type of glass that is more resistant to damage. This can help to prevent costly repairs and replacements in the future.

    Overall, it's important to work with a professional glass supplier who can provide you with expert advice and guidance on choosing the right type of glass for your needs. A good supplier will take the time to understand your specific requirements and will be able to recommend the best type of glass for your situation.

  • Can I use self-cleaning glass for my shower screen? It is not recommended to use self-cleaning glass for your shower screen. Self-cleaning glass is designed for use on exterior windows and requires water and sunlight to activate the cleaning process. In a shower environment, the glass would not be exposed to enough sunlight to activate the self-cleaning properties, and the water from the shower would not be sufficient to clean the glass effectively. Instead, you should use regular glass for your shower screen and clean it regularly with a glass cleaner and a soft cloth.
  • I have a broken down double glazed unit, do I need to replace it with another with up to date U values? No, Document L only applies when the whole window, including the frame is replaced. However, Regulations linked to safety will apply.
  • I would like to put a mirror on the wall which houses a plug socket, will I need to have the socked moved first? No. We are able to measure and make cut outs in the mirror to enable sockets to still be used. However, the wiring will need to be long enough to allow for the extra spacing.
  • What is 'U-value'? The U-Value is a measure of how effective a commercial window is at insulating a building. It is expressed in units of W/m²K, which stands for watts per square meter per kelvin. The lower the U-Value, the better the window is at preventing heat from escaping the building. For example, a window with a U-Value of 1.5 W/m²K will allow less heat to escape than a window with a U-Value of 2.0 W/m²K.

    When choosing commercial windows for your business, it's important to consider the U-Value to ensure that you are getting the best possible thermal performance. In general, windows with a low U-Value will be more expensive than those with a high U-Value, but they will also save you money on your energy bills in the long run. If you operate a business in a climate with cold winters, you may want to invest in windows with a very low U-Value to keep your building warm and reduce your heating costs. Additionally, low-U-Value windows can improve the comfort of your employees and customers, which can be an important factor in creating a positive experience for them.
  • Can we open an account for future use? We are happy to open Accounts for new Commercial Customers, subject to the normal checks. Unfortunately, we do not open accounts for the domestic market, with the exception of 'Landlord's'.
  • Will installing Double Glazing instead of the single glazing I have at present cure condensation problems inside my windows? While installing double glazing can help reduce condensation on your windows, it is not a guarantee that it will completely solve the problem. This is because condensation is caused by a number of factors, including excess moisture in the air and poor ventilation. Double glazing can help by providing an extra layer of insulation, which can prevent warm, moisture-laden air from coming into contact with the cold surface of your windows. However, in order to fully address condensation issues, you will also need to make sure that your home is adequately ventilated and that you are using your heating properly.

    When it comes to ventilation, it's important to make sure that you have enough fresh air coming into your home to replace the moist air that is produced by activities like cooking, showering, and laundry. This can be achieved through a combination of natural ventilation, such as opening windows and doors, and mechanical ventilation, such as using extractor fans or air conditioning units.

    In terms of heating, it's important to make sure that your home is warm enough to prevent condensation from forming on your windows. This means setting your thermostat to a comfortable temperature and using your heating system regularly to maintain a consistent level of warmth throughout your home. It's also a good idea to avoid placing furniture or other objects too close to your windows, as this can block the flow of warm air and create cold spots where condensation is more likely to form.

    In summary, while installing double glazing can help reduce condensation on your windows, it is not a guaranteed cure. To fully address condensation issues, you will need to make sure that your home is adequately ventilated and that you are using your heating properly.

  • Why does my double glazing have moisture inside and look fogged up? Double glazing can sometimes fail and become misty, cloudy or blown. Double glazing is held together by a seal around the edge that prevents moisture getting in. Double glazed windows normally contain special gases such as Argon, which escapes when there is a broken or faulty seal. The broken seal allows regular air and moisture into the panes of glass, causing condensation to form. The condensation can appear as water droplets or streaks within the glazing. The condensation forms when there is a difference in temperature either side of the pane, causing the moisture to condense on the double glazing and form the water droplets in the glazing. It is important to fix faulty double glazing as this can cause damage to your property by rotting your window frame or a build-up of black mould. Condensation in double glazing becomes unsightly and causes a fogged and misty view. In winter, the broken double glazing may let heat out of your property costing you money.
  • How do I know if my double glazing is blown? One of the most obvious signs that your double glazed window has blown is the presence of water droplets between the panes of glass. This is often the result of a seal failure, which allows moisture to enter the space between the panes and condense there. In addition to water droplets, you may also notice a draught coming from the window, which is another common symptom of a blown window. Another way to tell if your double glazing has blown is to look for visible damage to the panes of glass. This can include cracks, chips, or other defects that may have occurred due to age, wear and tear, or exposure to extreme temperatures. If you notice any of these issues, it's important to have the window repaired or replaced as soon as possible to prevent further damage. In addition to the problems mentioned above, a blown double glazed window can also cause water to leak through the frame and into the surrounding wall or ceiling. This can lead to rot, mould, and other issues that can cause significant damage to your home. To prevent this from happening, it's important to have any blown windows repaired or replaced as soon as possible to prevent further damage.
  • Why are my double pane windows cloudy? Double pane windows become cloudy if the seal that protects them is broken. The seal that runs around the edge of the glass is used to keep a special gas locked inside. The gas, typically Argon, will leak out and be replaced with normal air which contains moisture. The difference in air temperature from outside to inside the building will cause condensation to form, which results in a cloudy mist on the inside of the window pane.
