Insulation and Energy Efficiency

Homes in Aberdeen with single glazing or old inefficient double glazing lose a lot of heat through their windows. With a high energy-efficiency rating, Greencastle windows prevent this problem by improving thermal efficiency. 

The two panes of glass (or three if you opt for triple-glazing) and an insulating barrier of gas between the glazing mean that more heat stays inside your home instead of escaping outside. This reduces energy costs because you can keep your home warm and comfortable without having to crank up the heating too much.

Less Noise

When you install double glazing windows, you’ll soon notice how much quieter your home is. The windows significantly reduce external noise pollution – crucial if you have noisy neighbours or live near a busy road.

The double glazing absorbs sound vibrations and sound also struggles to pass through the uPVC frames. This means double-glazed uPVC windows can reduce noise inside your home by 65 percent or more.

Strong Security

Double glazing provides an important home security measure to help keep out intruders and make sure your family and belongings are safe. Unlike standard single-glazed windows, double glazing is difficult to break through without using noisy power tools – the last thing burglars want to do.

Greencastle windows come with steel-reinforced uPVC frames as standard, and these also make forced entry more difficult. As a further security measure, our windows have Yale multi-point locking systems.

Increased Home Value

Installing double glazing can be a smart investment in your home, especially if you decide to sell up at some point.

By increasing the market appeal and resale value of your property, double glazing gives you a better chance of selling your home at a much better price. It’s estimated that replacing single glazing with double glazing can increase a home’s value by up to 10%.

UV Protection

sash windows installed in bedroom

Despite generally low summer temperatures, the Granite City still gets a lot of sun – more than 1,450 hours of sunshine in a typical year. This can cause problems as UV (ultraviolet) rays penetrate into homes through windows. These issues include premature ageing of skin and damage to home furnishings and fabrics.

With built-in UV screening, double glazing windows in Aberdeen stop up to 99% of ultraviolet rays getting into homes. 

Less Condensation

Reducing noise with double glazing

Condensation is a common issue in homes with single-glazed windows. It can result in mould growing on damp patches on walls and ceilings, and this can lead to respiratory illnesses. Over time, condensation can also cause structural damage.

The insulating gas between the two panes of double glazing dramatically reduces condensation and its associated risks – by up to 85%.

Easy Maintenance

Taking care of your windows will be a breeze. Unlike timber window frames, uPVC doesn’t require periodic maintenance such as repainting and varnishing. You simply wipe the frames and window panes down from time to time using water and a mild detergent.

Double Glazed Windows FAQs

Most frequent questions and answers about double glazing in Aberdeen

You generally don’t need planning permission for double-glazing installation. However, Aberdeen City Council says that if you’re installing double glazing in a listed building or in a conservation area you’ll typically require listed-building consent or planning permission, respectively.

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

On average, they last 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 may last as long as 50 years.

Regular cleaning and maintenance can make your 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.
