Double Glazed Windows FAQs

Double glazing works by trapping air between two panes of glass, in order to provide a strong barrier, helping to insulate the space, regulating the interior temperature, and keeping the weather outside from getting inside. Energy efficient double glazed windows consist of a frame (this can be timber, aluminium, uPVC, or composite depending on your personal preference) with two sealed glass units fitted inside, according to the style of the window. Energy efficient glazing is rated according to its ability in reducing the amount of heat that can pass through the window. Our double glazing Scotland is A+ rated, meaning after installation, you will quickly see your energy bills, heat loss, and amount of condensation reduced.

If your window problem is quite minor, you may be able to repair the issue yourself. However, it is always best to have your window looked at by a specialist to determine if it can be fixed, or you will need a replacement window. You will likely need new windows if:

  •       Your windows don’t open and close easily– in this case, the window frames could have warped, began to rot, or are maybe the wrong size.
  •       Your windows are draughty– this problem occurs when a window does not shut properly, the locking system no longer works, or the windows are single glazed. Windows that have double glazing are substantially more energy-efficient than single glazed windows, so you may end up saving a lot of money on your heating bills by switching to double glazing.
  •       You can hear outside noise from inside your home when the window is closed– this is typically a sign that the windows are old and are due to be replaced.
  •       Your window is leaking– this is a sign that the seals around the glass have gone, so replacing your existing windows with new double glazed ones will be the most cost-effective option.

·        Your windows are over 15 years old– it is recommended that you consult an expert if an old window is still in good enough condition or if a replacement double glazed window will be necessary.

Each home is different, and this means it is difficult to provide an upfront cost of installing double glazing as it depends on the individual project. The cost of double glazed windows will be based on multiple elements including style, size, fitting costs, non-standard shapes, the handles, accessories, and what glass detailing options you select.

Having your old windows replaced with new double glazed ones will add value to your property. Double glazed windows are an essential factor for many potential buyers viewing houses. Window installations typically will cost about 2-3% of the home’s value (depending on style, size, and number of windows needed) and even though this is and upfront cost, it can be paid off with our flexible payment terms of up to 10 years, and in the long-term replacing your old windows with new high-quality ones from Clyde will increase your home’s value and improve energy efficiency, and therefore effectively pay for itself.

We understand that secure windows are essential in any home, therefore all of our windows are designed and built with your safety in mind. Double glazing naturally offers a greater level of security than single glazing as there are two panes of glass which makes it harder to break. Also, all of our windows feature industry-leading locking systems to give you complete peace of mind and confidence in your home’s windows.

The days of plain windows with limited options are well and truly over, we offer a range of standard colour options for your new windows in Scotland. One popular option is uPVC woodgrain finish which gives you the look of real wood without the maintenance that would usually come with it. Also, you could have dual colours with white inside and a second colour outside so you can keep to the style and character of your property in both your interior and exterior.

With so many options now available and multiple decisions to make, it can be tricky to settle on which type of windows is the right choice for you and your home. Each one has its own advantages which we will go through to help you determine the most suitable material for your new windows.


Timber is the highest performing material in terms of energy efficiency, due to it being a natural insulator that absorbs and retains heat. It is also often perceived as the most attractive, but as wood is a natural material it does require more maintenance to keep it looking its best.


uPVC is long-lasting and low maintenance as well as offering impressive performance at an affordable price. It is a popular material choice for many homeowners as it ticks a lot of boxes, it’s an all-round good material that gives you a smooth look that won’t ever rot, rust, or flake but it may lack a bit of charm for some buyers looking for a material with more character.


Slim frames like ones made from aluminium allow the most light in and provide a stylish exterior for modern properties. Aluminium is often used in structural glazing and other commercial construction due to its strength, which is why the frames can be made thinner in comparison to the other materials. As a metal, aluminium is a natural heat conductor, meaning heat escapes easily. So, aluminium windows need a thermal barrier in the frames to reduce heat loss which has helped improve their popularity as a window frame option.


Composite windows offer the benefits of all of the other materials combined, including strength, security, energy efficiency, aesthetics, and longevity. For example, one popular choice is to create aluminium-clad timber for a low maintenance, weatherproof window thanks to the aluminium outside, that also has the character and warmth of a classic wooden window on the inside.

Choosing window styles to fit your home is essential, but there are limitations on certain properties and types of windows that will fit. For example, if your property is a listed building or within a conservation area, there will be restrictions on what you can get, and you should seek advice before starting to make changes. Casement windows can be customised to fit any size; however, sash windows will fit into specific parameters.

Our window fitters in Scotland are extremely professional and careful to minimise the impact of their work, to avoid any damage to walls or floors when installing your windows. So, you should not need to re-decorate your room as a result of having new windows fitted.

It is normal to have condensation on the outside of new double glazed windows. This is because it is blocking the heat from inside your home escaping outside hence the outside windows are cooler and condensation occurs. If condensation is appearing on the inside of your windows, then you may have other issues. Keep an eye out for any damage to the seals around the windows as this could allow water in.
