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 Bishopton
Quality Energy Efficient Double Glazed Windows & Doors




You’ve felt the temperature dropping in your house. Energy bills are up. Condensation forms on or inside your windows each morning.
Ring a bell? Your windows are telling you a message.
As windows wear, they start to lose their seal.
The gas between the panes leaks out, the rubber gaskets stiffen and pull back, and what once kept the cold now hardly makes a difference.
Bishopton gets its fair share of rain and wind, frequently more than sunshine. When your windows are worn, you notice the difference in how warm and cosy your house stays.
No need to panic about it! The Advanced Group has been in the business for over 38 years. Whether you need new windows for just one room or every room of replacement windows and doors, we’ll match you with the right solution and get it all fitted the right way.

Some issues are obvious, like cracked glass, rotten timber frames, and handles that won’t lock correctly.
Other signs are less easy to spot. By the time you do, they’ve been losing you money for months or years.

Moisture or fogging between the two sheets of glass is a tell-tale sign. The sealed unit has broken down.
The seal goes. The argon gas leaks out. The window loses a large portion of its thermal efficiency.
Don’t let climbing heating costs drain your budget. Bring back your home’s thermal performance by installing perfectly sealed new windows.

Place your hand near the window edges on a windy day. Cold air coming through? The seals have worn away.
Sure, draught proofing strips can do something for a while, but they’re really a sticking plaster. The problem only deteriorates as the rubber keeps degrading.

Windows that jam, won’t close right, or refuse to budge are both a safety risk and an insulation issue. Warped frames, worn hinges, failed mechanisms. The window has come to the end of its working life.
Multi-point locking systems on modern windows are much more protective than the single-point catches on older windows, and options like toughened glass give further protection.
Windows lose a large amount of your home’s heat. They’re the barrier between you and the outside world.
Your old double glazing? It’s a thing of the past! The energy ratings are well below what’s achievable now, even if the original setup was solid back then.
Installing new double glazed windows and doors is one of the smartest ways to shield your home from high energy costs.

Every Bishopton house is different, and the right window style depends on the house, the room, and how you live in it.
The Advanced Group has a wide range of double glazed and triple glazed windows and doors in stock, including uPVC casement, sash, tilt and turn, and top hung designs, all provided and installed by our installers.

Casement windows are probably the UK’s most popular window style! They’re side-hinged, open outwards, and are perfect for ventilation and easy to clean from inside.
Modern home or traditional property, casement windows complement the lot. A wide selection of colours and finishes is available, and the woodgrain effects capture the look of timber without any of the maintenance or warping worries.

The original look of wooden sash frames, mirrored in every detail. That’s what our sliding sash windows deliver, along with modern thermal efficiency and security.
The proportions, sight lines, and opening mechanism all mirror the traditional design, which matters if your property is in a conservation area or you simply want to preserve its character.

Tilt and turn windows tilt inward at the top for secure ventilation, and turn fully inward on a side hinge for simple cleaning.
They’re particularly well-liked in upper-floor flats, where getting up a ladder to clean the outside of the glass isn’t realistic.
The tilt feature is a proper benefit! You get airflow without the safety concerns of a fully open window, which is particularly useful if you’ve got young children at home.
Top hung windows open outward from the bottom while being hinged at the top, which is great for letting air in without letting rain through.
You’ll often spot them in bathrooms, kitchens, stairwells, and bay window configurations, places where both privacy and airflow count.

French windows function just like French doors but are full-length windows that open outward.
Paired together, they look wonderfully and can be paired with sidelights to cover a wide opening with glass and natural light.
uPVC frame materials. That’s what The Advanced Group specialises in, and the reasons are sound.
Scottish weather is brutal. uPVC is designed to handle it. Durable, tough to wild, windy, wet conditions. No warping or rot worries like timber.
On top of that, uPVC is incredibly low maintenance.
Wipe it down with soapy water. Done. Looks good as new.
And here’s the truly exciting part: our uPVC windows are seriously energy efficient! Designed with multi-chambered uPVC, some of our frames reach a U-value as low as 0.8 W/m2K, which genuinely works to restore your home’s energy efficiency.
The best part? uPVC double glazing is the most affordable option available.
This means you to often select higher-specification glazing without exceeding your budget. We also offer glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.
Cold, wet, and windy. That’s Scotland for a fair portion of the year.
With a climate like that, the energy performance of your windows makes a noticeable difference to what you shell out on heating and how comfortable your house feels from day to day!
Familiar with U-values? That’s how the thermal performance of any window is measured.
The lower that figure, the less heat gets out through your glass and frame. Scottish building regulations currently cap it at 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 effective as the regulatory minimum, comfortably.
The difference appears on your energy statements.
Argon gas filled sealed units and low-E glass coatings perform the hard work in A-rated energy-efficient windows and doors. Heat gets bounced back in. Light still comes through.
If you are switching from old single-glazed sash windows or early double glazing from the 1990s, you should see a noticeable drop in your heating costs within the first winter.
Bishopton has no shortage of double glazing businesses. Few match the calibre of our windows and doors.

Our trusted installers are often asked about the triple glazing options we supply.
An extra pane of glass. Improved insulation. Greater noise control. That’s triple glazing.
Exposed spot? Up a hill? Facing north? Near a busy road or flight path? The Advanced Group will walk you through the benefits of triple glazing.

We understand that new windows are an big purchase, and paying for them all at once isn’t always feasible.
To support with this, we provide 0% APR and up to 4 years of interest free credit.
This enables you to get the windows you deserve while spreading the cost of your new windows and doors in a way that suits your circumstances.
