We’ve installed thousands of windows over the last 34 years, take a look at what we have installed more recently.
Fitting Scotland Perfectly
New Windows St Andrews
Quality Energy Efficient Double Glazed Windows & Doors




Maybe you’ve noticed a change in temperature in your home. Energy bills rising. Or condensation gathering on or inside your windows in the morning.
Does that hit home? Your windows are sending a signal something’s.
The seal on older windows breaks down over time.
The gas between the panes gradually seeps out, the rubber gaskets go rigid and contract, and what once held the cold out now hardly makes any difference.
In St Andrews, where the rain and wind can seem more frequent than sunshine, tired windows really change how warm and comfortable your home feels.
But there’s no need to worry, The Advanced Group is here to lend a hand with more than 38 years of trusted service. Whether it’s new windows for one room or a complete house of replacement windows and doors, we’ll find you the right fit and have everything fitted the right way.

Cracked glass? Rotten timber frames? Handles that don’t lock right? Some problems are easy to spot.
Some signs fly under the radar though, and by the time you notice them, they’ve been silently costing you money for months or even years.

If you notice moisture or fogging between the two panes of glass, this is a strong sign that the sealed unit has failed.
Once that seal goes, the argon gas that delivers insulation escapes out, and your window loses a big chunk of its thermal efficiency.
Why throw money away on rising heating bills? Restore your home’s thermal performance with well sealed new windows instead.

A windy day reveals you all you need to know. Hold your hand near the edges of the window. Cold air getting through tells you the seals have gone.
Draught proofing strips might help in the short term, but they’re just a sticking plaster on a fault that’ll only get worse as the rubber keeps perishing.

Windows that catch, won’t lock properly, or refuse to budge are both a safety risk and an insulation problem. Warped frames, worn hinges, failed mechanisms. The window has come to the end of its working life.
Multi-point locking systems on modern windows are considerably more secure than the single-point catches on older frames, and options like toughened glass give extra security.

Windows leak a significant share of your home’s heat. They’re the barrier between you and the outside elements.
Old double glazing can’t compare. The energy ratings are well below what’s available now, even if the original specification was solid at the time.
Guard your home from high energy bills with new double glazed windows and doors.

No two St Andrews properties are the same, and the best window type hinges on the building, the room, and how you use it.
We supply and install a full range of double glazed and triple glazed windows and doors, including uPVC casement, sash, tilt and turn, and top hung styles.

Possibly the most widely chosen window style in the UK, casement windows are side-hinged and open outwards, which makes them great for ventilation and simple to clean from inside.
Casement windows suit most property types, from modern houses to traditional villas, and are available in a wide choice of colours and finishes, including woodgrain effects that recreate the look of timber without the maintenance and fear of warping.

Want the appearance of original wooden sash frames? Our sliding sash windows replicate that classic look while delivering modern thermal efficiency and security.
Every proportion, sight line, and opening mechanism follows the traditional look. Whether your property sits in a conservation area or you simply want to hold onto its personality, these windows deliver.

Tilt and turn windows tilt inward at the top for safe ventilation, and turn completely inward on a side hinge for easy cleaning.
If you are in an upper-floor flat, these are a great option because cleaning the outside of the glass from a ladder just isn’t realistic.
The tilt mode delivers airflow without safety concerns. Especially valuable for families with young children.
Top hung windows are hinged at the top and open outward from the bottom. This makes them a practical choice for ventilation while working to hold rain out.
They are often used 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.
They look well in pairs and can be paired with sidelights to fill a wide opening with glass and natural light.

uPVC frame materials. That’s what The Advanced Group specialises in, and the reasons are good.
uPVC frame materials are especially well suited to the harsh Scottish weather, delivering durability and resilience to wild, windy, and wet weather. Unlike timber frames, uPVC won’t suffer from the same warping or rot issues.
Better still, uPVC is really low maintenance.
Wipe it down with soapy water. Job done. Looks as good as new.
And here’s the genuinely 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 really works to restore your home’s energy efficiency.
On top of all that, uPVC double glazing is also the most budget-friendly option out there.
That means you can often upgrade to higher-specification glazing without blowing the budget! We also offer glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.
Scotland’s weather is cold, wet, and windy for a fair chunk of the year.
In such a weather pattern, the energy rating of your windows has a noticeable effect on your heating spend and the overall warmth of your house day to day.
A window’s thermal efficiency is measured by something called its U-value.
Lower number, less heat escaping. Scottish building regulations currently require a maximum of 1.6 W/m2K for replacement windows.
Our standard double glazed windows achieve 1.2 W/m2K, and our premium options can reach 0.8 W/m2K! That’s performance at twice the regulatory minimum!
You’ll see the difference on your energy bills.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings reflect heat back into the room while still allowing light through.
If you are switching from old single-glazed sash windows or early double glazing from the 1990s, you should see a noticeable decrease in your heating costs within the first winter.
There are plenty of double glazing businesses in St Andrews offering entry-level products, but not many can come close to the calibre of what we provide.

Our experienced installers are frequently asked about our triple glazing range.
An extra pane of glass makes triple glazing apart. It delivers better insulation and improved noise dampening beyond standard double glazing.
If your property is in an exposed area, at a raised altitude, facing north, or close to a busy road or flight path, The Advanced Group would be more than happy to walk you through the benefits of triple glazing.

New windows are an investment. Paying for everything at once? Not always practical. We get that.
That’s why we offer 0% APR and up to 4 years of interest free credit, making the purchase much less stressful!
This allows you get the windows you want by spreading the cost of your new windows and doors in a way that fits with your finances.
