We’ve installed thousands of windows over the last 34 years, take a look at what we have installed more recently.

Quality Energy Efficient Double Glazed Windows & Doors




You’ve spotted the temperature shifting in your house. Bills are rising. Condensation sits on or inside your windows every morning.
If that describes your situation, your windows are giving you a clear signal.
Older windows drop their seal over time.
That gas between the panes? It escapes. The rubber gaskets harden and contract. And what used to keep the cold out barely slows it down.
In a city like Newton Stewart, where rain and wind are sometimes more common than sunshine, worn windows have a clear effect on how warm and comfortable your house feels.
But there’s no need to worry, The Advanced Group is here to support you with more than 38 years of trusted service. Whether it’s new windows for a single room or a full house of replacement windows and doors, we’ll find you the right option and get everything fitted the right way.

Some issues are clear. Cracked glass, rotten timber frames, handles that don’t lock correctly.
But other symptoms are harder to notice, and by the time you spot them, they’ve already been losing you money for months, maybe even years.

Moisture or fogging between the two sheets of glass? The sealed unit has gone.
Once the seal has broken, the argon gas that provides insulation leaks, and the window loses a significant amount of its thermal performance.
Climbing heating prices don’t have to keep eating into your pocket. Properly sealed new windows will recover your home’s thermal efficiency and start to pull those costs back down.

Hold your hand near the window edges on a windy day. Cold air sneaking through? The seals have gone.
Draught proofing strips give a temporary fix, but they’re really a sticking plaster on a problem that will only worsen as the rubber keeps perish.

If your windows catch, won’t close properly, or are hard to open, this presents both a safety risk and an insulation problem. Warped frames, worn hinges, and failed mechanisms are all indicators that the window has come to the end of its useful life.
The single-point catches on older windows don’t compete with the multi-point locking systems on modern ones. Throw in toughened glass, and your property has a real safety improvement.
Your windows are responsible for a large amount of the heat loss in your property. They’re the barrier between you and the outside world.
Older double glazing is a thing of the past, and the energy ratings will be well below what’s available now, even if they were a good specification when they were first fitted.
Installing new double glazed windows and doors is one of the best ways to protect your house from high energy bills.

Every house in Newton Stewart is different. The right window choice depends on the building, the room, and how you occupy it.
The Advanced Group stocks and installs a full range of windows and doors in double glazed and triple glazed options, including uPVC casement, sash, tilt and turn, and top hung types.

As very likely the most common window type in the UK, casement windows are side-hinged and open outwards, offering effective ventilation and easy cleaning from inside.
Casement windows suit most property types, from modern homes to traditional villas, and are offered in a wide range of colours and finishes, including woodgrain effects that recreate the look of timber without the maintenance and risk of warping.

Our sliding sash windows are made to mirror the style of original wooden sash frames, while offering modern levels of thermal performance and protection.
The proportions, sight lines, and opening mechanism all stay true to the traditional style, which is brilliant if your property’s in a conservation area or you just want to keep its personality.

These windows tilt inward at the top for safe ventilation and turn fully inward on a side hinge for effortless cleaning.
Well-liked in upper-floor flats. Cleaning the outside from a ladder? Not realistic.
Airflow without the safety concern of a fully open window. That’s what the tilt feature delivers, and it’s particularly valuable for families with young children.
Hinged at the top, opening outward from the bottom. Practical for ventilation and good at keeping rain out.
They are often used in bathrooms, kitchens, stairwells, bay window setups, and other spaces where privacy and airflow are both valued.

French windows are full-length panels that open outward, operating similar to French doors.
Perfect in pairs. Match them with sidelights to open up a wide opening with glass and natural light.
There are good reasons why The Advanced Group focuses in uPVC frame materials.
Scotland’s weather doesn’t take it easy on your windows, and uPVC is designed to handle it. It’s durable, resistant to rough, windy, wet weather, and unlike timber, it won’t rot the same way.
And there’s another benefit: uPVC is seriously low maintenance!
Simply wipe it down with soapy water and it can look good as new.
Quite possibly most importantly, our uPVC windows deliver high levels of energy performance. Designed with multi-chambered uPVC, some of our frames achieve a U-value as low as 0.8 W/m2K, helping to restore energy efficiency throughout your property.
On top of all that, uPVC double glazing is also the most cost-effective option on the market.
This means you can often fit higher-specification glazing without breaking 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 large part of the year.
That weather means the energy rating of your windows makes a difference. It affects how much you spend on heating and how cosy your property feels every single day.
A window’s thermal efficiency is measured by something called its U-value.
The lower the number, the less heat gets out through the glass and frame. Scottish building regulations currently demand a maximum U-value of 1.6 W/m2K for replacement windows.
Standard double glazed windows: 1.2 W/m2K. Premium options: as low as 0.8 W/m2K. That’s twice as good as the regulatory minimum.
You’ll spot the difference on your energy costs.
A-rated windows and doors. Argon gas filled sealed units. Low-E glass coatings. Heat pushed back in, light still flowing through.
Upgrading from old single-glazed sash windows or 1990s double glazing? You could see a real drop in heating spend within the first winter.
Many double glazing companies in Newton Stewart supply entry-level products, but few can compete with the quality of the windows and doors we provide.

We get asked about triple glazing a lot.
Triple glazing has an extra pane of glass, allowing it to offer enhanced insulation and greater noise control.
If your property is positioned in an exposed location, 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 willing to guide you through the benefits of triple glazing.

We know that new windows are an significant spend, and paying for them all at once isn’t always feasible.
That’s precisely why we have available 0% APR and up to 4 years of interest free credit.
This helps you get the windows you deserve by spreading the cost of your new windows and doors in a way that works around your budget.
