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 Oxton
Quality Energy Efficient Double Glazed Windows & Doors




Maybe you’ve felt a shift in temperature around your house. Energy bills climbing. Or condensation collecting on or inside your windows every morning.
That nagging feeling? It’s your windows signalling to you they’re past their best.
Windows don’t keep their seal indefinitely, and older ones lose theirs over time.
Between the panes, the gas leaks. The rubber gaskets harden and contract. What once held the cold back now barely registers.
In a place like Oxton, where rain and wind are often more frequent than sunshine, tired windows have a real effect on how warm and cosy your home feels.
The Advanced Group is here to help, bringing over 38 years of trusted service. Whether you want new windows for a single room or a full house of replacement windows and doors, we’ll help you find the right fit and ensure everything is fitted correctly.

Certain issues are hard to miss. Cracked glass, rotten timber frames, handles that don’t fasten correctly.
But other signs are less obvious, and by the time you catch them, they’ve already been losing you money for months or even years.

Can you notice moisture or fogging forming between the two sheets of glass? That means the sealed unit has given way.
Once the seal fails, the argon gas that provides insulation leaks out, and the window loses a significant amount of its thermal performance.
Climbing heating costs don’t have to keep going up. Properly sealed new windows will recover your home’s thermal performance and help pull those costs back down.

Place your hand near the window edges on a windy day. Cold air coming through? The seals have worn away.
Draught proofing strips offer a short-term measure, but they’re really a sticking plaster on a problem that will only worsen as the rubber goes on to break down.

Got windows that seize, won’t fasten right, or just refuse to budge? That’s a security risk and an insulation issue rolled into one. Warped frames, worn hinges, and failed mechanisms all tell you the window has hit the end of its useful life.
Modern windows come with multi-point locking systems that are far ahead of the single-point catches on older models. Factor in toughened glass, and you’ve got properly stronger protection.

Windows lose a significant share of your home’s heat. They’re the bridge between you and the outside weather.
Your old double glazing? It’s had its day! The energy ratings are well below what’s on offer now, even if the original setup was good when first installed.
High energy costs don’t have to be the default. New double glazed windows and doors work to shield your property and keep those costs down.

Oxton homes come in all forms, and the right window choice depends on your house, the room, and how you live in it.
The Advanced Group has a complete lineup of double glazed and triple glazed windows and doors available, including uPVC casement, sash, tilt and turn, and top hung styles, all provided and installed by our team.
Casement windows could well be the UK’s most common window type! They’re side-hinged, open outwards, and are great for ventilation and simple to clean from inside.
Casement windows match just about every property style, whether it’s a modern house or a traditional property! They are available in a wide range of colours and finishes, and the woodgrain effects mimic real timber without the maintenance or warping worries.

The sliding sash windows we supply recreate the look of original wooden sash frames, while delivering modern thermal efficiency and protection.
Proportions, sight lines, and opening mechanism all mirror the traditional design. Perfect for conservation areas or maintaining your property’s personality.
Tilt and turn windows are genuinely practical! They tilt inward at the top for secure ventilation and swing fully inward on a side hinge for simple cleaning.
Upper-floor flat? Cleaning outside glass from a ladder isn’t realistic. Tilt and turn windows solve that problem completely.
The tilt mode gives airflow without safety risks. Particularly valuable for families with young children.
Top hung windows hinge at the top and open outward from the bottom. This makes them a smart choice for ventilation while helping to keep rain out.
You’ll spot top hung windows in bathrooms, kitchens, stairwells, and bay window setups, basically anywhere that privacy and airflow are both important.

French windows are full-length windows that open outward just like French doors.
They perform well in pairs and can be matched with sidelights to fill a wide opening with glass and natural light.

There are good reasons why The Advanced Group specialises in uPVC frame materials.
Scotland’s weather won’t play nice with your windows, and uPVC is designed to handle it. It’s tough, resilient to wild, windy, wet conditions, and unlike timber, it won’t deteriorate the same way.
On top of that, uPVC is really low maintenance.
Soapy water and a wipe. That’s all it takes to keep uPVC looking brand new.
Quite possibly most importantly, our uPVC windows offer impressive levels of energy performance. Built with multi-chambered uPVC, some of our frames achieve a U-value as low as 0.8 W/m2K, helping to restore energy efficiency across your home.
The icing on the cake? uPVC double glazing is the most budget-friendly option available.
Higher-spec glazing without exceeding the budget? That’s what uPVC allows. We also supply glazed uPVC doors, including uPVC doors, composite doors, and patio doors to go with.

Scotland gives cold, wet, and windy weather for a large chunk of the year.
In that weather, the energy performance of your windows makes a noticeable difference to how much you spend on heating and how cosy your house feels on a daily basis.
The thermal performance of any window is measured by its U-value.
The lower the figure, the less heat gets out through the glass and frame. Scottish building regulations currently require a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows attain a U-value of 1.2 W/m2K, while our premium models can achieve values as low as 0.8 W/m2K, working at twice the level of the regulatory minimum.
The difference is reflected on your energy bills.
Argon gas filled sealed units and low-E glass coatings do the heavy lifting in A-rated energy-efficient windows and doors. Heat gets reflected back in. Light still gets through.
If you’re coming from old single-glazed sash windows or early double glazing from the 1990s, you could see a properly significant drop in your heating costs within even the first winter!
Oxton has plenty of double glazing companies. Few rival the calibre of our windows and doors.

Our trusted installers are frequently asked about the triple glazing options we offer.
An extra pane of glass. Stronger insulation. Improved noise reduction. That’s triple glazing.
If your property is positioned in an exposed area, 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.
0% APR. Up to 4 years interest free credit. That’s what we provide.
It means you can get the windows you need through helping you spread the cost of your new windows and doors in a way that fits for you.
