We’ve installed thousands of windows over the last 34 years, take a look at what we have installed more recently.

New Windows Middleton Park
Quality Energy Efficient Double Glazed Windows & Doors




Noticed a temperature drop in your house? Energy costs on the increase? Or condensation appearing on or inside your windows when you wake up?
Does that ring true? Your windows are letting you know they need replacing.
Over time, older windows start to lose their seal.
The gas between the panes escapes out, the rubber gaskets stiffen and contract, and what used to kept the cold now hardly does anything.
In a place like Middleton Park, where rain and wind are often more regular than sunshine, worn windows have a real impact on how warm and cosy your home feels.
The Advanced Group is here to support you, with 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 work with you to choose the right option and ensure everything is installed the right way.

Some signs are hard to miss. Cracked glass, rotten timber frames, handles that don’t fasten correctly.
But other signs are harder to notice, and by the time you spot them, they’ve probably already been costing you money for months, maybe even years.

Seeing moisture or fogging between your two sheets of glass means the sealed unit has broken down.
The seal fails. The argon gas seeps out. The window loses a significant amount of its thermal efficiency.
Don’t let rising heating bills chip away at your budget. Recover your home’s thermal efficiency by fitting properly sealed new windows.

Try holding your hand near the edges of your window on a windy day. If you notice cold air getting through, the seals have broken down.
Draught proofing strips? They’re a short-term fix. The problem only worsens as the rubber keeps perish.

Windows that stick, won’t close properly, or refuse to open are both a safety risk and an insulation problem. Warped frames, worn hinges, failed mechanisms. The window has reached the end of its functional life.
Modern windows feature multi-point locking systems that are miles ahead of the single-point catches on older models. Throw in toughened glass, and you’ve got significantly stronger security.

Your windows are where a significant share of your home’s heat escapes. That thin boundary between you and the outside world matters more than most people expect.
Older double glazing is a thing of the past, and the energy ratings will be far below what’s on offer now, even if they were a good specification when they were first put in.
Want to protect your property from those high energy costs? New double glazed windows and doors are the solution.

Every house in Middleton Park is different. The right window type depends on the house, the room, and how you occupy it.
The Advanced Group supplies and fits a full selection of windows and doors in double glazed and triple glazed options, including uPVC casement, sash, tilt and turn, and top hung styles.

Quite likely the most common window style in the UK, casement windows are side-hinged and open outwards, which makes them practical for ventilation and simple to clean from inside.
They fit most styles of property, from modern homes to traditional villas, and come in a wide choice of colours and finishes. Woodgrain effects replicate the look of timber without the maintenance or worry of warping.
The sliding sash windows we install replicate the look of original wooden sash frames, while offering modern thermal efficiency and safety.
The proportions, sight lines, and opening mechanism all follow 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 are really practical! They tilt inward at the top for secure ventilation and swing completely inward on a side hinge for easy cleaning.
If you live in an upper-floor flat, these are a great choice because cleaning the outside of the glass from a ladder just isn’t realistic.
Airflow without the security worry of a fully open window. That’s what the tilt mode delivers, and it’s particularly handy for families with young children.

Top hung windows are hinged at the top and open outward from the bottom, giving a smart option for ventilation that also works to keep rain out.
They’re often chosen in bathrooms, kitchens, stairwells, bay window configurations, and other spaces where privacy and airflow are just as valued.

French windows are full-length windows that open outward like French doors.
Perfect in pairs. Pair them with sidelights to fill a wide opening with glass and natural light.

uPVC frame materials. That’s what The Advanced Group specialises in, and the reasons are good.
Scottish weather throws the lot at your windows. uPVC is designed to withstand it, tough, resistant to rough, windy, wet conditions, and free from the warping or rot issues that come with timber frames.
What’s more, uPVC is also low maintenance.
Wipe it down with soapy water. That’s it. Looks fresh.
The real benefit? Energy efficiency. Our uPVC windows feature multi-chambered uPVC, and some frames reach a U-value as low as 0.8 W/m2K. That brings back proper energy efficiency to your home.
Best of all? uPVC double glazing is the most affordable option.
So you can often install higher-specification glazing and still keep within budget. We also stock glazed uPVC doors too, including uPVC doors, composite doors, and patio doors to complement.
Cold, wet, and windy. That’s Scotland for a good chunk of the year.
With weather like that, the energy efficiency of your windows makes a noticeable difference to what you spend on heating and how pleasant your home feels day to day!
A window’s thermal performance is measured by something called 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 achieve 1.2 W/m2K, and our premium models can achieve values as low as 0.8 W/m2K. That’s top-performing double glazing and triple glazing that works twice as well as the regulatory minimum.
The difference turns up on your energy statements.
A-rated windows and doors. Argon gas filled sealed units. Low-E glass coatings. Heat pushed back in, light still coming through.
If you’re coming from old single-glazed sash windows or early double glazing from the 1990s, you could see a properly noticeable drop in your heating bills within even the first winter!
There are lots of double glazing businesses in Middleton Park selling entry-level products, but not many can come close to the quality of what we fit.
We get asked about triple glazing all the time.
An extra pane of glass makes triple glazing apart. It delivers improved insulation and improved noise control beyond standard double glazing.
Exposed location? Up a hill? Facing north? Near a busy road or flight path? The Advanced Group will walk you through the advantages of triple glazing.

We completely get that new windows are an investment, and paying for everything at once isn’t always realistic.
To help with this, we provide 0% APR and up to 4 years of interest free credit.
It means you can get the windows you deserve through helping you spread the cost of your new windows and doors in a way that suits for you.
