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




Spotted a temperature change in your house? Heating bills on the up? Or condensation appearing on or inside your windows in the morning?
Ring a bell? Your windows are telling you a clear sign.
As windows get older, they gradually lose their seal.
The gas between the panes slowly leaks, the rubber gaskets stiffen and pull back, and what used to blocked the cold out now hardly makes any difference.
In Selkirk, where the rain and wind can seem more regular than sunshine, ageing windows really impact how warm and comfortable your home feels.
Not to worry. The Advanced Group offers over 38 years of trusted experience. Single room or full house, replacement windows or doors, we’ll find the right solution and install everything correctly.

Some problems are straightforward, such as cracked glass, rotten timber frames, and handles that won’t fasten the right way.
Other signs, however, are less obvious, and by the time you notice, they could have been costing you money for months or even years.

Moisture or fogging between the two sheets of glass? The sealed unit has broken down.
Once the seal has gone, the argon gas that delivers insulation seeps away, and the window loses a substantial portion of its thermal performance.
Why throw money away on increasing heating prices? Bring back your home’s thermal efficiency with perfectly sealed new windows today.

Put your hand near the window edges on a windy day. Cold air sneaking through? The seals have deteriorated.
Draught proofing strips buy you time, but they’re a sticking plaster at best. The rubber continues to perishing, and the problem only worsens.

Got windows that seize, won’t close right, or just refuse to play along? 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 come to the end of its working life.
Multi-point locking systems outperform the old single-point catches for security. Toughened glass gives another layer of protection.

Windows contribute to a considerable amount of heat loss in any property. It is the barrier between you and the outside weather.
Your old double glazing? It’s outdated! The energy ratings are well below what’s on offer today, even if the original specification was good when first installed.
Guard your home from rising energy bills. New double glazed windows and doors make the difference.

Every Selkirk house has its own character. The right window style depends on the house, the room, and how you live in it.
A full lineup of windows and doors, double glazed and triple glazed, is ready from The Advanced Group, including uPVC casement, sash, tilt and turn, and top hung designs, all provided and installed by our team.
The most popular window type in the UK. Side-hinged, opening outwards. Great for ventilation and easy to clean from inside.
Ideal for most property kinds, from modern builds to traditional villas, casement windows come in a wide choice of colours and finishes, including woodgrain effects that mimic the look of timber without the maintenance or risk of warping.

The sliding sash windows we install recreate the appearance of original wooden sash frames, while providing modern thermal performance and safety.
The proportions, sight lines, and opening mechanism all stay true to the traditional design, which is brilliant if your property’s in a conservation area or you just want to maintain its charm.
Tilt and turn windows tilt inward at the top for secure ventilation, and turn fully inward on a side hinge for easy cleaning.
They’re a well-liked choice for upper-floor flats where cleaning the outside of the glass from a ladder isn’t an option.
The tilt mode provides airflow without the safety concerns that come with a fully open window, which is particularly helpful 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 working to hold rain out.
You’ll often spot them in bathrooms, kitchens, stairwells, and bay window configurations, spaces where both privacy and airflow are important.

French windows look just like French doors but are full-length windows that open outward.
In pairs, they work stunning, and you can combine them with sidelights to open up a wide opening with glass and plenty of natural light.

There are sound reasons why The Advanced Group focuses in uPVC frame materials.
Scottish weather can be wild, but uPVC withstands it all! It’s durable, stands up to wind, rain, and the roughest of it, and you won’t get the warping or rot problems that timber frames come with.
Better still, uPVC is incredibly low maintenance.
Just a simple wipe with soapy water and it can look brand new!
More to the point though, our uPVC windows are highly energy effective. With multi-chambered uPVC engineering, some of our frames can reach a U-value as low as 0.8 W/m2K, working to bring back your home’s energy performance.
And better of all? uPVC double glazing is also the most affordable option.
That lets you can often step up to higher-spec glazing without blowing the budget! We also offer glazed uPVC doors, including uPVC doors, composite doors, and patio doors to coordinate.

Scotland’s weather is cold, wet, and windy for a good part of the year.
With that environment, your windows’ energy rating genuinely influences your heating costs and how cosy your property feels every day.
A window’s thermal performance is measured by what’s known as its U-value.
The lower that value goes, the less heat is lost. Scottish building regulations require the maximum at 1.6 W/m2K for replacement windows currently.
Our standard double glazed windows sit at 1.2 W/m2K. The premium range? As low as 0.8 W/m2K. Twice as effective as the regulatory minimum, comfortably.
That performance gain is clearly reflected on your energy statements.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings are amazing at bouncing heat back into the room while still letting plenty of light through.
If you’re swapping out old single-glazed sash windows or early double glazing, you could notice a real drop in your heating bills within the first winter.
Many double glazing firms in Selkirk supply standard products, but few can match the calibre of the windows and doors we install.

We get asked about triple glazing a lot.
An extra pane of glass makes triple glazing apart. It translates to stronger insulation and improved noise control beyond standard double glazing.
If your property is situated 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 glad to guide you through the advantages of triple glazing.

New windows are an big purchase. Paying for them all at once? Not always practical. We understand that.
That’s why we offer 0% APR and up to 4 years of interest free credit, to make the purchase much less stressful!
The windows you deserve, with the cost spread in a way that fits for you. That’s what 0% finance allows.
