New Windows Duddingston
Quality Energy Efficient Double Glazed Windows & Doors




You’ve spotted the temperature shifting in your house. Bills are up. Condensation gathers on or inside your windows each morning.
That nagging feeling? It’s your windows telling you something.
As windows wear, they lose their seal.
That gas between the panes? It escapes. The rubber gaskets harden and shrink. And what once kept keep the cold out barely does the job.
In Duddingston, where the rain and wind can seem more regular than sunshine, tired windows truly change how warm and cosy your home feels.
The Advanced Group is here to help, bringing over 38 years of trusted experience. Whether you are looking for new windows for a single room or a full house of replacement windows and doors, we’ll work with you to choose the right option and make sure everything is fitted correctly.

Some problems are hard to miss. Cracked glass, rotten timber frames, handles that won’t fasten correctly.
Other signs are trickier to notice. By the time you do, they’ve been costing you money for months or years.

Can you notice moisture or fogging trapped between the two sheets of glass? That means the sealed unit has broken down.
Once the seal has failed, the argon gas that provides insulation leaks, and the window loses a considerable chunk of its thermal performance.
Why waste money away on climbing heating costs? Bring back your home’s thermal performance with perfectly sealed new windows today.

Try putting your hand near the edges of your window on a windy day. If you feel cold air sneaking through, the seals have broken down.
Draught proofing strips? They’re a quick fix. The fault only worsens as the rubber keeps perish.

If your windows catch, won’t lock properly, or are hard to open, this creates both a safety risk and an insulation issue. Warped frames, worn hinges, and failed mechanisms are all signs that the window has come to the end of its working life.
Multi-point locking systems on modern windows provide far greater security than the single-point catches used in older frames, and toughened glass choices add an additional layer of safety.

Your windows are where a considerable proportion of your home’s heat gets out. That thin barrier between you and the outside world matters more than most people think.
Your old double glazing? It’s a thing of the past! The energy ratings are well below what’s on offer now, even if the original setup was decent back then.
Guard your house from high energy bills with new double glazed windows and doors.

Every Duddingston house has its own feel. The right window type comes down to the property, the room, and how you occupy it.
The Advanced Group supplies and fits a full range of windows and doors in both double glazed and triple glazed options, including uPVC triple and double and triple glazed casement, sash, tilt and turn, and top hung styles.
The most widely fitted window type in the UK. Side-hinged, opening outwards. Practical for ventilation and easy to clean from inside.
Perfect for most property kinds, from modern homes to traditional villas, casement windows are available in a wide choice of colours and finishes, including woodgrain effects that mimic the look of timber without the maintenance or risk of warping.

The sliding sash windows we fit replicate the style of original wooden sash frames, while providing modern thermal efficiency and security.
The proportions, sight lines, and opening mechanism are all designed to follow the traditional design, which is especially relevant if your property is in a conservation area or you wish to maintain its personality.
Tilt inward at the top for secure ventilation. Turn fully inward on a side hinge for easy cleaning.
For homeowners in upper-floor flats, tilt and turn windows are a popular choice, as cleaning the outside of the glass from a ladder isn’t practical.
The tilt function allows air in without the security concerns of having the window fully open, which is especially valuable if you’ve got young children.
Top hung windows are hinged at the top and open outward from the bottom, providing a sensible choice for ventilation that also helps to keep rain out.
They are often fitted in bathrooms, kitchens, stairwells, bay window arrangements, and other spaces where privacy and airflow are equally important.

French windows are full-length windows that open outward like French doors.
Paired together, they work brilliantly and can be paired with sidelights to cover a wide opening with glass and natural light.

The Advanced Group specialises in uPVC frame materials, and for very good reasons!
Scotland’s weather won’t play nice with your windows, and uPVC is built to take it. It’s tough, resistant to harsh, windy, wet conditions, and unlike timber, it won’t deteriorate the same way.
On top of that, uPVC is incredibly low maintenance.
Simply wipe it down with soapy water and it can look fresh.
Here’s the truly big part: our uPVC windows are highly energy efficient! Made with multi-chambered uPVC, some of our frames achieve a U-value as low as 0.8 W/m2K, which seriously helps restore your home’s energy efficiency.
And the best part? uPVC double glazing is the most budget-friendly option out there.
So you can often choose premium-grade glazing and still keep within budget. We supply glazed uPVC doors too, including uPVC doors, composite doors, and patio doors to complement.

For a significant chunk of the year, Scotland’s climate is cold, wet, and windy.
With that climate, your windows’ energy performance directly affects your heating bills and how cosy your house feels day to day.
The thermal efficiency of any window is measured by its U-value.
The lower that number goes, the less heat gets through. Scottish building regulations cap the maximum at 1.6 W/m2K for replacement windows right now.
Our standard double glazed windows deliver 1.2 W/m2K, and our premium products can hit values as low as 0.8 W/m2K. That’s superior double glazing and triple glazing that performs twice as well as the regulatory minimum.
The difference appears on your energy bills.
A-rated energy-efficient windows and doors feature argon gas filled sealed units and low-E glass coatings to reflect heat back into the room, all while letting natural light through.
If you are upgrading from old single-glazed sash windows or early double glazing from the 1990s, you should experience a clear reduction in your heating bills within the first winter.
While many double glazing companies in Duddingston supply basic products, few can rival the standard of the windows and doors we supply.

We get asked about triple glazing regularly.
Triple glazing includes an extra pane of glass, which delivers stronger insulation and noticeably greater noise control.
If your property is positioned in an exposed spot, up a hill or high above sea level, facing north, or near a busy road or under a flight path, The Advanced Group would be more than glad to guide you through the advantages of triple glazing.

We understand that new windows are a notable spend, and paying for them in full all at once isn’t always possible.

The windows you want, with the cost spread in a way that suits for you. That’s what 0% finance opens up.
