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




If you’ve spotted a temperature drop in your house, or seen your bills climbing, or condensation forming on or inside your windows in the morning, it’s time taking notice.
If that seems familiar, your windows are sending you something.
Old windows shed their seal with age.
The gas between the panes seeps out, the rubber gaskets harden and pull back, and what once held back the cold now hardly makes a difference.
In a city like Old Kilpatrick, where rain and wind can frequently feel more frequent than the sun, worn windows make a real difference to how warm and cosy your home feels.
Over 38 years in the business, and The Advanced Group is still here, ready to support you. Whether it’s one room or the whole house that is due new windows and doors, we’ll find the right option and have everything fitted just right.

Some issues are straightforward, like cracked glass, rotten timber frames, and handles that don’t fasten properly.
Some signs fly under the radar however, and by the time you notice 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 broken down.
The seal breaks, and with it goes the argon gas that delivered the insulation. The window loses a significant portion of its thermal performance.
Don’t throw money away with rising heating costs and make sure to bring back your home’s thermal efficiency with properly sealed new windows.

Try holding your hand near the edges of your window on a windy day. If you notice cold air coming through, the seals have worn away.
Draught proofing strips may help in the short term, but they’re only a sticking plaster on a issue that’ll only get worse as the rubber keeps perishing.

Seizing windows that won’t close right aren’t just annoying, they’re a security risk and an insulation problem too. Warped frames, worn hinges, and failed mechanisms all signal a window that’s come to the end of its working life.
Multi-point locking systems on modern windows are far more safe than the single-point catches on older windows, and options like toughened glass provide additional safety.
A large proportion of heat loss in any property happens through the windows. They form the boundary between your indoor space and the outside weather.
Double glazing from years ago is a thing of the past, and the energy ratings will be well below what’s available today, even if the spec was decent at the time.
Guard your house from expensive energy costs. New double glazed windows and doors make the difference.

Old Kilpatrick houses come in all forms, and the right window choice depends on your house, the room, and how you live in it.
The Advanced Group offers a full range of windows and doors in both double glazed and triple glazed configurations, including uPVC casement, sash, tilt and turn, and top hung styles.

Quite likely the most common window choice in the UK, casement windows are side-hinged and open outwards, which makes them ideal for ventilation and straightforward to clean from inside.
They suit most types of property, from modern builds to traditional villas, and come in a wide range of colours and finishes. Woodgrain effects replicate the look of timber without the maintenance or worry of warping.

The classic look of wooden sash frames, replicated in every detail. That’s what our sliding sash windows deliver, along with modern thermal efficiency and safety.
The proportions, sight lines, and opening mechanism all match the traditional look, which matters if your property is in a conservation area or you simply want to maintain its charm.

Tilt inward at the top for safe ventilation. Turn completely inward on a side hinge for easy cleaning.
For those living in upper-floor flats, tilt and turn windows are a wise choice, as cleaning the outside of the glass from a ladder isn’t practical.
The tilt feature provides airflow without the safety concerns that come with a fully open window, which is especially helpful for families with young children.
Top hung windows are hinged at the top and open outward from the bottom, making them a practical choice for ventilation while helping to keep rain out.
They are commonly fitted in bathrooms, kitchens, stairwells, bay window configurations, and other spaces where privacy and airflow are equally needed.

French windows are full-length panels that open outward, functioning similar to French doors.
They look well in pairs and can be matched with sidelights to open up a wide opening with glass and natural light.
There are solid reasons why The Advanced Group specialises in uPVC frame materials.
Scottish weather dishes out all sorts at your windows. uPVC is designed to handle it, hardwearing, resilient to rough, windy, wet weather, and without the warping or rot issues that plague timber frames.
uPVC is low maintenance too.
Wipe it down with soapy water. Done. Looks good as new.
But more to the point, our uPVC windows are extremely energy efficient. Built with multi-chambered uPVC, some of our frames can hit a U-value as low as 0.8 W/m2K, helping bring back energy performance to your house.
And the best bit? uPVC double glazing is the most budget-friendly option out there.
That lets you can often upgrade to higher-specification glazing without breaking the budget! We also supply glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.
For a large chunk of the year, Scotland’s climate is cold, wet, and windy.
In such a weather pattern, the energy rating of your windows has a real effect on your heating bills and the overall cosiness of your house on a daily basis.
The thermal efficiency of any window is measured by its U-value.
The lower that number, the less heat is lost through your 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 deliver a U-value of 1.2 W/m2K, while our premium range can reach values as low as 0.8 W/m2K, working at twice the standard of the regulatory minimum.
And where does that difference show up? Straight on your energy costs!
Argon gas filled sealed units and low-E glass coatings do the real work in A-rated energy-efficient windows and doors. Heat gets bounced back in. Light still gets through.
Moving from old single-glazed sash windows or 1990s double glazing? Expect a noticeable drop in heating spend within the first winter.
Many double glazing businesses in Old Kilpatrick offer entry-level products, but few can compete with the quality of the windows and doors we install.

Triple glazing is among the most frequent questions our trusted installers hear.
Triple glazing packs in an extra pane of glass, which gives improved insulation and clearly greater noise reduction.
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 benefits of triple glazing.

We appreciate that new windows are a notable purchase, and paying for them in full all at once isn’t always possible.
So we make available 0% APR and up to 4 years of interest free credit. Simple.
It lets you get the windows you need and spread the cost of your new windows and doors in a way that suits comfortably for you!
