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

New Windows Oldtown
Quality Energy Efficient Double Glazed Windows & Doors




A shift in temperature inside the house. Rising bills. Condensation collecting on or inside the windows come morning. Sound familiar?
If that describes your home, your windows are giving you a message.
Over time, older windows begin to lose their seal.
The gas between the panes gradually escapes, the rubber gaskets go rigid and contract, and what used to blocked the cold out now scarcely holds it back.
In Oldtown, where the rain and wind can feel more common than sunshine, tired windows really change how warm and comfortable your home feels.
But not to worry, The Advanced Group is here to assist with over 38 years of trusted experience. Whether you require new windows for a single room or a full house of replacement windows and doors, we can guide you to the right fit and get everything fitted the right way.

Cracked glass? Rotten timber frames? Handles that don’t lock properly? Some signs are hard to miss.
Other signs are harder to notice. By the time you see them, they’ve been costing you money for months or years.

Noticing moisture or fogging between your two panes of glass tells you the sealed unit has given up.
When the seal goes, the argon gas that delivers insulation leaks, and the window loses a considerable amount of its thermal efficiency.
Why throw money away on increasing heating prices? Recover your home’s thermal efficiency with well sealed new windows today.

Hold your hand near the edges of the window on a windy day. If you can feel cold air sneaking in, the seals have deteriorated.
Draught proofing strips? They’re a quick fix. The fault only gets worse as the rubber keeps perish.

Jamming windows that won’t close right aren’t just annoying, they’re a security risk and an insulation concern too. Warped frames, worn hinges, and failed mechanisms all point to a window that’s reached the end of its useful life.
Multi-point locking systems on modern windows are much more safe than the single-point catches on older frames, and options like toughened glass add further security.

Your windows are behind a significant amount of the heat loss in your house. They’re the barrier between you and the outside world.
Double glazing from the past is exactly that, in the past. The energy ratings land far below today’s options, even if the original specification was reasonable when first installed.
Guard your house from expensive energy bills. New double glazed windows and doors deliver the difference.

Oldtown homes come in all forms, and the right window style depends on your building, the room, and how you use it.
The Advanced Group supplies and fits a full selection of windows and doors in both double glazed and triple glazed setups, including uPVC triple and double and triple glazed casement, sash, tilt and turn, and top hung styles.

Casement windows are likely the most popular window style in the UK. They’re side-hinged and open outwards, making them great for ventilation and easy to clean from inside.
Modern house or traditional villa, casement windows suit the lot. A wide choice of colours and finishes is provided, and the woodgrain effects capture the look of timber without any of the maintenance or warping worries.
Our sliding sash windows mirror original wooden sash frames. Modern thermal performance and safety are built in as standard.
Proportions, sight lines, and opening mechanism all match the traditional design. Perfect for conservation areas or keeping your property’s charm.

These windows tilt inward at the top for secure ventilation and turn fully inward on a side hinge for easy cleaning.
Well-liked in upper-floor flats. Cleaning the outside from a ladder? Not an option.
The tilt feature allows air in without the safety risks of having the window fully open, which is particularly valuable if you’ve got young children.

Top hung windows are hinged at the top and open outward from the bottom, making them a smart choice for ventilation while working to keep rain out.
Bathrooms, kitchens, stairwells, bay window configurations, anywhere privacy and airflow both count. That’s where top hung windows come into their own.

French windows are full-length windows that open outward, operating similar to French doors.
Pair them up and combine them with sidelights, and you can fill a wide opening with glass and natural light. The effect is striking.

The Advanced Group specialises in uPVC frame materials, and for some genuinely good reasons!
Scotland’s weather doesn’t play nice with your windows, and uPVC is designed to withstand it. It’s durable, resilient to harsh, windy, wet weather, and unlike timber, it won’t rot the same way.
And there’s another benefit: uPVC is really low maintenance!
Soapy water and a cloth. That’s all it takes to keep uPVC looking fresh.
But more significantly, our uPVC windows are very energy performant. Built with multi-chambered uPVC, some of our frames can achieve a U-value as low as 0.8 W/m2K, helping restore energy efficiency to your property.
Best of all? uPVC double glazing is the most cost-effective option.
This means you can often fit premium-grade glazing without breaking the budget. We also provide glazed uPVC doors, including uPVC doors, composite doors, and patio doors to coordinate.
Scotland’s weather is cold, wet, and windy for a fair part of the year.
With weather like that, the energy performance of your windows makes a real difference to what you pay on heating and how warm your house feels day to day!
The thermal efficiency of a window is determined by its U-value.
The lower that value goes, the less heat is lost. Scottish building regulations set the maximum at 1.6 W/m2K for replacement windows at present.
Our standard double glazed windows perform at 1.2 W/m2K. The premium options? As low as 0.8 W/m2K. Twice as good as the regulatory minimum, without question.
You’ll spot the difference on your energy bills.
A-rated energy-efficient windows and doors use argon gas filled sealed units and low-E glass coatings to bounce heat back into the room, all while letting natural light through.
If you’re moving from old single-glazed sash windows or early double glazing from the 1990s, you could see a real drop in your heating spend within the first winter.
While many double glazing firms in Oldtown offer entry-level products, few can match the calibre of the windows and doors we install.
Our trusted installers welcome chatting about triple glazing, and it’s a topic that pops up frequently!
Triple glazing adds an extra pane of glass, which provides better insulation and noticeably greater noise dampening.
If your property is in an exposed position, at a raised altitude, facing north, or close to a busy road or flight path, The Advanced Group would be more than willing to walk you through the benefits of triple glazing.

We totally appreciate that new windows are an significant spend, and paying for them all at once isn’t always practical.
0% APR. Up to 4 years interest free credit. That’s what we provide.
