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 Bearsden
Quality Energy Efficient Double Glazed Windows & Doors




You’ve spotted the temperature dropping in your house. Bills are climbing. Condensation forms on or inside your windows each morning.
Does that ring true? Your windows are telling you something’s.
As windows get older, they gradually lose their seal.
Between the panes, the gas escapes. The rubber gaskets harden and contract. What once blocked the chill now barely slows it down.
Living in Bearsden, you understand that rain and wind sometimes outnumber the sunny days, and ageing windows make a noticeable difference to how warm and comfortable your house feels.
The Advanced Group is here to support you, bringing over 38 years of trusted expertise. 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 solution and make sure everything is fitted properly.

Some problems are obvious, like cracked glass, rotten timber frames, and handles that won’t lock properly.
Some signs fly under the radar though, and by the time you pick up on them, they’ve been silently losing you money for months or even years.

If you can notice moisture or fogging between the two sheets of glass, the sealed unit has given way.
The seal breaks. The argon gas leaks out. The window loses a major chunk of its thermal performance.
Don’t let rising heating bills chip away at your budget. Recover your home’s thermal efficiency by installing perfectly sealed new windows.

On a windy day, place your hand near the edges of the window. If you can feel cold air getting through, this means the seals have broken down.
Draught proofing strips offer you time, but they’re a sticking plaster at most. The rubber keeps breaking down, and the issue only gets worse.

Sticking windows that won’t lock right aren’t just frustrating, they’re a security risk and an insulation concern too. Warped frames, worn hinges, and failed mechanisms all signal a window that’s reached the end of its useful life.
Multi-point locking systems far exceed the old single-point catches for safety. Toughened glass adds further protection.
A significant amount of heat loss in any home occurs through the windows. They act as the bridge between your indoor space and the outside elements.
Your old double glazing? It’s outdated! The energy ratings are far below what’s on offer today, even if the original specification was solid when first installed.
High energy bills don’t have to be the default. New double glazed windows and doors help protect your home and keep those costs down.

Every Bearsden property has its own character. The right window type comes down to the building, the room, and how you live in it.
The Advanced Group has a full selection of double glazed and triple glazed windows and doors available, including uPVC casement, sash, tilt and turn, and top hung designs, all supplied and fitted by our team.

The most popular window style in the UK. Side-hinged, opening outwards. Practical for ventilation and simple to clean from inside.
Casement windows complement just about any property style, whether it’s a modern build or a traditional house! They are available in a huge range of colours and finishes, and the woodgrain effects look just like real timber without the maintenance or warping worries.

The traditional look of wooden sash frames, recreated in every detail. That’s what our sliding sash windows offer, along with modern thermal efficiency and safety.
The proportions, sight lines, and opening mechanism are all made to match the traditional style, which is especially valuable if your property is in a conservation area or you wish to maintain its charm.

Tilt inward at the top for safe ventilation. Turn fully inward on a side hinge for easy cleaning.
If you live in an upper-floor flat, these are a great pick because cleaning the outside of the glass from a ladder just isn’t practical.
The tilt function lets air in without the security concerns of having the window wide open, which is especially helpful if you’ve got young children.
Top hung windows are hinged at the top and open outward from the bottom, offering a smart choice for ventilation that also works to keep rain out.
You’ll often see them in bathrooms, kitchens, stairwells, and bay window setups, places where both privacy and airflow matter.

Think of them as full-length windows that open outward, much like French doors. That’s French windows in a nutshell.
Great in pairs. Match them with sidelights to flood a wide opening with glass and natural light.
The Advanced Group specialises in uPVC frame materials for sound reasons.
Scotland’s weather won’t go easy on your windows, and uPVC is designed to withstand it. It’s durable, resilient to harsh, windy, wet conditions, and unlike timber, it won’t warp the same way.
Better still, uPVC is incredibly low maintenance.
Simply wipe it down with soapy water and it can look good as new.
And here’s the really important part: our uPVC windows are seriously energy efficient! Built with multi-chambered uPVC, some of our frames hit a U-value as low as 0.8 W/m2K, which really helps restore your home’s energy efficiency.
And best of all? uPVC double glazing is also the most cost-effective option.
This means you can often choose premium-grade glazing without breaking the budget. We also offer glazed uPVC doors, including uPVC doors, composite doors, and patio doors to coordinate.
Let’s be real, Scotland is cold, wet, and windy for a good 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 cosiness of your house on a daily basis.
U-value. That’s the figure that reveals you how effective a window really is.
A lower U-value indicates less heat getting 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 sit at 1.2 W/m2K. The premium models? As low as 0.8 W/m2K. Twice as efficient as the regulatory minimum, without question.
The difference shows up on your energy bills.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings are brilliant at reflecting heat back into the room while still letting loads of light through.
Old single-glazed sash windows or 1990s double glazing? Replace them, and you could see a noticeable drop in heating bills before the first winter is out.
While many double glazing companies in Bearsden offer standard products, few can compare with the calibre of the windows and doors we supply.

Our experienced installers are regularly asked about our triple glazing products.
Triple glazing includes an extra pane of glass, which delivers improved insulation and clearly better noise dampening.
Exposed location. Up a hill. Facing north. Near a busy road or under a flight path. If any of those rings true like your property, The Advanced Group is on hand to guide you through the advantages of triple glazing.

We totally appreciate that new windows are an significant spend, and paying for them all at once isn’t always doable.
To help with this, we provide 0% APR and up to 4 years of interest free credit.
Get the windows you want. Spread the cost in a way that fits for you.
