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 Clydebank
Quality Energy Efficient Double Glazed Windows & Doors




Maybe you’ve noticed a change in temperature inside your house. Energy bills climbing. Or condensation collecting on or inside your windows every morning.
If that seems familiar, your windows are sending you a message.
Old windows drop their seal with age.
The gas between the panes steadily seeps out, the rubber gaskets go rigid and pull back, and what once kept the cold out now scarcely makes any difference.
Clydebank’s rain and wind can feel more common than the sun. Tired windows make a clear difference to how warm and cosy your home feels.
Not to worry. The Advanced Group has over 38 years of trusted expertise. Single room or full house, replacement windows or doors, we’ll find the right fit and install everything right.

The easy ones stand out. Cracked glass, rotten timber frames, handles that refuse to lock properly.
Some signs fly under the radar though, and by the time you notice them, they’ve been quietly costing you money for months or even years.

If you can see moisture or fogging between the two panes of glass, this is a clear sign that the sealed unit has failed.
Once the seal fails, the argon gas that provides insulation leaks out, and the window loses a considerable amount of its thermal performance.
Increasing heating costs don’t have to keep climbing. Perfectly sealed new windows will bring back your home’s thermal efficiency and start to bring those bills back down.

A windy day shows you all you need to know. Hold your hand near the edges of the window. Cold air coming through means the seals have worn away.
Draught proofing strips can help temporarily, but they’re a sticking plaster on a fault that will only get worse as the rubber keeps on perish.

Got windows that seize, won’t close right, or just refuse to cooperate? That’s a safety risk and an insulation concern 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 beat the old single-point catches for protection. Toughened glass gives another layer of safety.
Windows leak a large share of your home’s heat. They’re the barrier between you and the outside weather.
Double glazing from the past is exactly that, in the past. The energy ratings land far below today’s standards, even if the original spec was solid at the time.
Choosing new double glazed windows and doors is one of the best ways to guard your home from high energy bills.

The right window style for your Clydebank property will depend on the house itself, the room in question, and how you live in it.
We supply and install a full range of double glazed and triple glazed windows and doors, including uPVC casement, sash, tilt and turn, and top hung types.

The most widely fitted window style in the UK. Side-hinged, opening outwards. Great for ventilation and simple to clean from inside.
Perfect for most property types, from modern houses to traditional houses, casement windows are offered in a wide range of colours and finishes, including woodgrain effects that recreate the look of timber without the maintenance or risk of warping.

Our sliding sash windows replicate the look of original wooden sash frames while offering modern thermal performance and protection.
Every proportion, sight line, and opening mechanism matches the traditional style. Whether your property sits in a conservation area or you simply want to keep its character, these windows deliver.

These windows tilt inward at the top for safe ventilation and turn completely inward on a side hinge for effortless cleaning.
Common in upper-floor flats. Cleaning the outside from a ladder? Not practical.
The tilt function is a genuine bonus! You get airflow without the security concerns of a fully open window, which is especially great if you’ve got young children at home.
Top hung windows are hinged at the top and open outward from the bottom. This makes them a practical choice for ventilation while helping to stop rain out.
You’ll find top hung windows in bathrooms, kitchens, stairwells, and bay window arrangements, essentially anywhere that privacy and airflow are both important.

Full-length windows that open outward like French doors. That’s exactly what French windows are.
They’re perfect 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 focuses in uPVC frame materials.
Scottish weather can be wild, but uPVC withstands it all! It’s long-lasting, resists wind, rain, and the roughest of it, and you won’t get the warping or rot problems that timber frames come with.
uPVC is low maintenance too.
Soapy water and a cloth. That’s all it takes to keep uPVC looking good as new.
More to the point though, our uPVC windows are seriously energy effective. With multi-chambered uPVC design, some of our frames can hit a U-value as low as 0.8 W/m2K, working to bring back your home’s energy performance.
Best of all? uPVC double glazing is the most cost-effective option.
That means you can often choose higher-spec glazing without breaking the budget. We also carry glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.
Scotland is cold, wet, and windy for a large chunk of the year.
With weather like that, the energy rating of your windows makes a real difference to what you shell out on heating and how cosy your home feels from day to day!
A window’s thermal efficiency is measured by what’s known as its U-value.
Lower value, less heat getting out. Scottish building regulations currently require a maximum of 1.6 W/m2K for replacement windows.
Our standard double glazed windows come in at 1.2 W/m2K, and our premium options can reach 0.8 W/m2K! That’s double glazing and triple glazing performing at twice the regulatory minimum!
And where does that difference appear? Straight on your energy costs!
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings reflect heat back into the room while still letting light through.
If you’re coming from old single-glazed sash windows or early double glazing from the 1990s, you could see a genuinely significant drop in your heating costs within even the first winter!
Many double glazing companies in Clydebank sell standard products, but few can compete with the standard of the windows and doors we fit.

Our experienced installers are often asked about our triple glazing range.
Triple glazing packs in an extra pane of glass, which provides stronger insulation and significantly better noise dampening.
If your property is perched in an exposed location, up a hill, facing north, or near a busy road or under a flight path, give us a shout! The Advanced Group would be more than pleased to talk you through the advantages of triple glazing.

We understand that new windows represent a notable purchase, and paying for them in full all at once isn’t always realistic.
So we offer 0% APR and up to 4 years of interest free credit. Simple.
This lets you get the windows you deserve by spreading the cost of your new windows and doors in a way that suits for you.
