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 Oakwood
Quality Energy Efficient Double Glazed Windows & Doors




A drop in temperature throughout the home. Increasing energy bills. Condensation collecting on or inside the windows every morning. Sound familiar?
If that sounds familiar, your windows are sending you something.
Over time, older windows start to lose their seal.
Between the panes, the gas leaks. The rubber gaskets stiffen and shrink. What used to blocked the chill now hardly slows it down.
In a location like Oakwood, where rain and wind are sometimes more regular than sunshine, tired windows have a real effect on how warm and comfortable your house feels.
But don’t worry, The Advanced Group is here to lend a hand with more than 38 years of trusted know-how. Whether it’s new windows for a single room or a full house of replacement windows and doors, we’ll help you find the right option and get everything fitted properly.

The easy ones jump out. Cracked glass, rotten timber frames, handles that won’t close properly.
But other signs are harder to notice, and by the time you catch them, they’ve probably already been losing you money for months, perhaps even years.

Noticing moisture or fogging between your two panes of glass means the sealed unit has given up.
Once the seal has broken, the argon gas responsible for insulation seeps away, and the window loses a substantial portion of its thermal performance.
Why waste money away on increasing heating costs? Restore your home’s thermal performance with properly sealed new windows today.

On a windy day, hold your hand near the edges of the window. If you can feel cold air getting through, this means the seals have worn away.
Draught proofing strips give a temporary measure, but they’re essentially a sticking plaster on a problem that will only deteriorate as the rubber keeps perish.

Windows that jam, bind, or won’t lock properly are a safety risk as well as an insulation problem. Warped frames, worn hinges, and failed mechanisms all point to the window has reached the end of its functional life.
Multi-point locking systems on modern windows are far more safe than the single-point catches on older models, and options like toughened glass provide further safety.

Windows leak a significant amount of your home’s heat. They’re the bridge between you and the outside weather.
Older double glazing is a thing of the past, and the energy ratings will be well below what’s out there now, even if they were a reasonable specification when they were first fitted.
Shield your home from rising energy bills. New double glazed windows and doors create the difference.

Every house in Oakwood is different. The right window choice depends on the property, the room, and how you live in it.
The Advanced Group offers and fits a full selection 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.

As perhaps the most widely chosen window style in the UK, casement windows are side-hinged and open outwards, providing effective ventilation and simple cleaning from inside.
Modern home or traditional villa, casement windows complement the lot. A wide selection of colours and finishes is provided, and the woodgrain effects mimic the look of timber without any of the maintenance or warping worries.

Want the style of original wooden sash frames? Our sliding sash windows replicate that traditional appearance while providing modern thermal performance and protection.
Proportions, sight lines, and opening mechanism all match the traditional style. Ideal for conservation areas or maintaining your property’s character.

Tilt inward at the top for safe ventilation. Turn fully inward on a side hinge for quick cleaning.
They’re a well-liked choice for upper-floor flats where cleaning the outside of the glass from a ladder isn’t feasible.
The tilt mode is a genuine bonus! You get airflow without the safety concerns of a fully open window, which is particularly great if you’ve got young children at home.
Top hung windows are hinged at the top and open outward from the bottom. This makes them a sensible choice for ventilation while working to stop rain from getting in.
You’ll find top hung windows in bathrooms, kitchens, stairwells, and bay window configurations, essentially anywhere that privacy and airflow are both needed.

French windows are full-length panels that open outward, operating much like French doors.
Paired together, they perform wonderfully and can be combined with sidelights to open up a wide opening with glass and natural light.

The Advanced Group’s focus is uPVC frame materials, and this decision is backed by good reasons.
uPVC frame materials are especially well suited to the harsh Scottish climate, delivering hardwearing performance and resilience to wild, windy, and wet weather. Unlike timber frames, uPVC won’t present the same warping or rot problems.
And here’s one more plus: uPVC is really low maintenance!
Simply wipe it down with soapy water and it can look fresh.
More importantly though, our uPVC windows are seriously energy efficient. With multi-chambered uPVC design, some of our frames can hit a U-value as low as 0.8 W/m2K, working to restore your home’s energy performance.
And the better part? uPVC double glazing is also the most affordable option out there.
That lets you can often step up to higher-specification glazing without breaking the budget! We also carry glazed uPVC doors, including uPVC doors, composite doors, and patio doors to coordinate.
Scotland dishes out cold, wet, and windy weather for a good part of the year.
In that environment, the energy rating of your windows makes a measurable difference to how much you spend on heating and how cosy your property feels every day.
U-value. That’s the figure that shows you how well-insulated a window really is.
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 come in at 1.2 W/m2K, and our premium models can reach 0.8 W/m2K! That’s double glazing and triple glazing performing at twice the regulatory minimum!
The evidence? It appears on your energy costs.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings send heat back into the room while still letting light through.
If you’re replacing old single-glazed sash windows or 1990s double glazing, you could see a noticeable drop in your heating spend within the first winter.
There are loads of double glazing firms in Oakwood selling standard products, but not many can come close to the quality of what we fit.

We get asked about triple glazing all the time.
The additional pane of glass in triple glazing allows it to deliver superior insulation and greater noise dampening.
If your property is situated 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 happy to guide you through the advantages of triple glazing.

New windows are an big purchase. Paying for them all at once? Not always realistic. We understand that.
