Impressive Energy Efficiency

GreenCastle double glazing has a high energy-efficiency rating, so it prevents a great deal of heat loss. This means lower energy bills and a reduced carbon footprint.

Our double-glazed windows can reduce heat loss (or heat gain) nearly 30% more efficiently than a single-glazed aluminium window.

Improved Security

The glass in double glazing is thicker than that of single-glazed windows, and with two layers of it, this provides better security against a break-in. 

GreenCastle double-glazed windows also incorporate cutting-edge security measures such as the Yale window locking system.

Less Condensation

UV protective double glazing in dundee home

Condensation is a common problem with single-pane windows. Over time it can cause not only structural damage but also result in growth of mould, which can trigger respiratory problems.

Insulating gas between the two panes of double glazing reduces condensation by up to 85%.

Noise Reduction

With GreenCastle double-glazed windows, your home will be a lot quieter. These windows reduce exterior noise pollution by up to 65% – 31 decibels. 

The two panes of glass and the gas between them absorb sound vibrations, which inhibits transmission of sound.

Besides double glazing, we can also improve old single-glazed windows by adding secondary glazing.

This is a cheaper option so could be the solution if you want to upgrade your windows on a budget.

At the other end of the glazing scale, we offer triple-glazed windows with outstanding thermal insulation.

UV Protection

GreenCastle double-glazed windows provide protection from the harmful effects of ultraviolet light from the sun entering your home.

The UV screen in our windows blocks up to 99% of UV rays. This avoids potential issues such as skin damage and furniture discolouration.

Double-Glazing Edinburgh - FAQs

Most frequent questions and answers

As long as your property isn’t a listed building or in a conservation area, you generally don’t need planning permission for double-glazed windows. 

The City of Edinburgh Council says that if you’re installing double glazing in a listed building, you’ll typically require listed-building consent. 

You’ll also need planning permission if windows would alter the external appearance of a building in a conservation area – replacing wood window frames with uPVC, or changing the original design, for instance.

The lifespan of double-glazed windows depends on factors such as the quality of the installation and materials, and how well the windows are maintained.

Double glazing on average lasts around 20 years. Your windows will last longer if your property is in a sheltered location that doesn’t expose them to extreme weather.

Some double-glazed windows may last 50 years.

Regular cleaning and maintenance can make your double-glazed windows last longer. 

Clean the glass and uPVC frames and sills with a soft cloth or sponge and a mild detergent. This will remove dirt without scratching the surfaces. 

Don’t use a high-pressure hose to clean your window exteriors. This can damage the seals and cause leakage. 

Window maintenance includes checking the condition of locks and seals frequently and ensuring any necessary repairs are done promptly.

Whether you need to replace a double-glazed window or have it repaired depends on what’s causing the problem.

If the integrity of the sealed unit has become compromised, you’ll usually need a full window replacement. 

If the problem is less serious, such as small cracks in the frame or damaged hardware, these issues can often be repaired. 

The price of double-glazed windows varies depending on the size of the window, quality of materials, level of customisation, and whether preparatory structural work like opening up a wall is needed.
