About Advanced Windows

At Advanced, all the windows, doors, and conservatories we provide to our valued Dundee customers are developed using the latest manufacturing techniques and innovative designs.

At one of Europe’s most advanced extrusion facilities pour fantastic range of uPVC products are manufactured in a way that meets all the sustainability requirements of the current climate, leading the future of triple and double glazing technology.


You may think that the glass is what really counts in a window, but the frame is an often overlooked and just as important.

Poorly installed frames are a major contributing factor to heat loss in properties across Scotland, costing homeowners thousands in the form of extortionate energy bills.

Our frames, on the other hand, are constructed with multiple internal chambers that act as a barrier to cold air from the outside and prevent the warm air generated from your heating system from escaping.

In order to further maximise the energy efficiency of our double and triple glazed window units, we use energy reflecting glass that transmits solar energy into your home.

Thermo space bars, are fitted to connect each pane of glass and eliminate colder areas around the edge of the pane, reducing the chances of condensation and further increasing unit performance.

Energy Efficiency

With energy prices soaring across the nation, and the current climate situation, increasing the energy efficiency of domestic homes has never been more important.

Over 20% of all the heat lost from a standard domestic home in Scotland is estimated to come directly as a result of poorly installed windows and doors.

For this reason, the energy efficiency of the unit is a crucial factor to consider when choosing your replacement windows, and at Advanced we are well ahead of the game in this regard.

A window’s energy efficiency is measured using u-values, with the lower a units u-value the more efficient it is at preventing unwanted heat transfer.

U-values take into account a wide range of factors including the window frame, glass pane, and spacer bars, and thanks to the expertise of those designing our windows, each of the components in our units excels when it comes to energy efficiency.

Our double glazed windows offer impressive U-values of 1.4 W/m2K (‘A’ Rated) as standard, with the option to further reduce this is 1.0 with our latest state-of-the-art insulated glass.

Our triple glazing combines 2 layers of our 1.0u to bring our insulation factor down to 0.6.

What does all this mean to a house owner?

The term U relates to the insulation provided in building products. The lower the figure, the better the insulation is. For example, a single pane window fitted 30 years ago has a U value of 6.0. Double glazing fitted 20 years ago and possibly fitted today by unscrupulous tradesmen is 3.0u. Our trade department supplies an excellent insulated glass unit providing an improvement of more than double at 1.4u.

For customers who want to super insulate there properties , we have sourced a glass that more than triples the insulation registering the insulation at 1.0u.

Finally, we can provide triple glazing for customers who want nothing but the best.

This glass will blow your mind!

It absolutely highlights the amount of heat lost out to the atmosphere. From single glazing to triple glazing, we will reduce the u value from 6.0 to 0.6. With 6.0 and 3.0 glass, so much heat escapes that the outer layer of glass remains dry or clear on cold or frosty days.

With our 1.0 and 0.6 glass units, virtually no heat escapes; therefore, the outside layer of glass will remain freezing and can show frost or moisture until the heat of the day clears it .
With these turbocharged units, you save so much more of your precious energy and helps to reduce your bills.

By carefully designing every component to create the most energy efficient unit possible product, having new windows and doors installed by one of our highly skilled fitters, could reduce your home heating bill by as much as 40%.

One of the biggest reasons that people choose to upgrade the windows and doors in their home is to increase security and to ensure that their loved ones are protected at all times.

Maximising security is one of the most important factors in our design process.

Double and triple glazing alone offers far more protection against intruders than traditional single glazing as there is an additional layer of reinforced glass between you and the outside.

Furthermore, our windows feature a range of the latest security technology, including internally glazed glass that ensures the protecting glazing bead cannot be removed from the exterior of the property, and a high performance multi-point locking system.

If you want to create the most robust and sturdy unit possible, we also offer toughened or laminated glass upon request.

To ensure the long-lasting durability of our products, all the hardware components in the unit are salt spray testing for 600 hours before being approved for production (3x longer than the industry standard).

Casement Windows

The most popular window type in the UK, casement windows are a practical and stylish classic.

They can be hinged to either side, offer excellent durability and versatility, and are one of the most energy efficient window types.

French Windows

With two separate openings, French windows work in a similar manner to French doors, offering unrivalled flexibility and an elegant finish.

Like patio doors, both sides of a French window can be opened to maximise ventilation and provide a usable fire escape when required.

Tilt and Turn Windows

Tilt and turn windows are similar to casement windows, with the additional advantage of being able to open the window in multiple ways.

Using an innovative hinge system, tilt and turn windows can either be ’tilted’ inwards for maximum ventilation or turned from the side up to 90 degrees inwards.

This flexibility means that tilt and turn windows offer all the same fantastic benefits of casement windows with the additional advantage of being able to use the unit as a fire escape in case of emergencies.

As a market leader, looking to take the lead in the future of window and door manufacturing, sustainability is at the heart of everything we do.

Low-Waste Manufacturing

By using innovative sustainable manufacturing processes we are able to significantly reduce the amount of waste produced by the production of our windows and doors, without compromising on quality or aesthetics.

As much as 80% of the materials used in our uPVC frames are recycled, and we ensure that every bit of waste that can be recycled is rather than sending it directly to landfill.

Not only will this save you money on expensive energy bills, but by reducing the amount of time your fossil fuelled heating system needs to be in operation to achieve a comfortable home temperature, you will also be doing your bit to reduce your carbon footprint and make your home more environmentally friendly.

Asked Questions

1. What sets apart "sash" windows from "casement" windows?

Sash windows are characterized by their traditional design, featuring a vertical sliding motion. On the other hand, casement windows offer greater flexibility with openers that can be pushed out or tilted in.

2. Do timber effect sash windows closely resemble real timber?

Our uPVC timber effect windows boast high-quality custom-made decorative finishes, providing a remarkably realistic appearance. We meticulously match these windows to existing frames, ensuring they are virtually indistinguishable from real timber, even at a distance.

3. What is the typical installation time for windows and doors?

The installation duration varies depending on site conditions and complexity. Generally, a two-person installation team can complete three to six windows per day.

4. Who installs your windows?

We exclusively deploy our fully trained and accredited in-house installers for all our projects.

5. Will removing window and door frames impact wiring or electrics in my home?

Typically, this is not an issue. However, if wiring is encountered during installation, work may be paused until a qualified electrician ensures a safe working environment.

6. Can burglars easily gain entry by removing the glass from your windows?

No, our Premier range features internally glazed windows, preventing the removal of glass from the outside unless it is broken. Glass removal can only occur from the inside.

7. Do your windows offer child safety features?

Certainly, we offer various safety and security solutions tailored to your needs. Our team will recommend the most suitable options at competitive prices.

8. Is cleaning obscure or decorative glass challenging?

No, as the pattern is on the inside of the pane, the outer surface of obscure or decorative glass is smooth, facilitating easy cleaning.

9. Do you have sash windows that tilt inwards for cleaning?

Yes, we offer such windows; however, sash horns cannot be included as they interfere with the tilting frame.
