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 Middleton
Quality Energy Efficient Double Glazed Windows & Doors




You’ve felt the temperature dropping in your home. Heating costs are climbing. Condensation sits on or inside your windows each morning.
Sound familiar? Your windows are telling you a message.
Older windows drop their seal over time.
Between the panes, the gas seeps away. The rubber gaskets stiffen and contract. What once kept the cold out now barely does a thing.
Middleton’s rain and wind can feel more common than the sun. Tired windows make a real difference to how warm and cosy your property feels.
But not to worry, The Advanced Group is here to support you with over 38 years of trusted expertise. Whether you require new windows for a single room or a full house of replacement windows and doors, we can help you find the right solution and get everything installed the right way.

Cracked glass? Rotten timber frames? Handles that don’t fasten properly? Some problems are pretty obvious.
Some signs slip under the radar however, and by the time you spot them, they’ve been silently costing you money for months or even years.

Moisture or fogging between the two sheets of glass? The sealed unit has failed.
When the seal goes, the argon gas that provides insulation escapes, and the window loses a significant portion of its thermal efficiency.
Don’t pour money away with rising heating costs and make sure to bring back your home’s thermal performance with well sealed new windows.

On a windy day, place your hand near the edges of the window. If you can feel cold air coming through, this suggests the seals have deteriorated.
Draught proofing strips might help for a while, but they’re really a sticking plaster on a problem that’ll only deteriorate as the rubber continues to degrading.

Windows that stick, won’t fasten correctly, 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 working life.
Multi-point locking systems far exceed the old single-point catches for protection. Toughened glass gives another layer of security.

Your windows are how a large proportion of your home’s heat is lost. That thin bridge between you and the outside elements makes a difference more than many people think.
Old double glazing doesn’t keep up. The energy ratings are significantly below what’s available today, even if the original spec was decent when first fitted.
Want to shield your home from those high energy costs? New double glazed windows and doors are the way forward.

Every Middleton home has its own feel. The right window type hinges on the property, the room, and how you use it.
The Advanced Group provides and fits a full range of windows and doors in double glazed and triple glazed configurations, including uPVC casement, sash, tilt and turn, and top hung types.

Casement windows are quite possibly the most popular window style in the UK. They’re side-hinged and open outwards, making them ideal for ventilation and straightforward to clean from inside.
Casement windows go with most property styles. Modern homes, traditional houses, the lot in between. Provided in a wide range of colours and finishes, including woodgrain effects that give the look of timber without the maintenance or warping risk.

The sliding sash windows we fit mirror the appearance of original wooden sash frames, while delivering modern thermal performance and security.
Every proportion, sight line, and opening mechanism matches the traditional design. Whether your property sits in a conservation area or you simply want to keep its charm, these windows deliver.

Tilt inward at the top for secure ventilation. Turn completely inward on a side hinge for easy cleaning.
Upper-floor flat? Cleaning outside glass from a ladder isn’t an option. Tilt and turn windows sort that challenge easily.
The tilt mode allows airflow without the safety worries that come with a fully open window, which is especially valuable for families with young children.
Top hung windows are hinged at the top and open outward from the bottom, giving a smart choice for ventilation that also works to keep rain out.
Bathrooms, kitchens, stairwells, bay window configurations, anywhere privacy and airflow both count. That’s where top hung windows work best.

Full-length windows that open outward like French doors. That’s what French windows deliver.
They’re ideal in pairs and can be paired with sidelights to open up a wide opening with glass and natural light.

We focus in uPVC frame materials. And for sound reason.
Scottish weather is harsh, and uPVC is built to be hardwearing and tough to harsh, windy, and wet weather. Unlike timber frames, uPVC won’t have the same warping or rot worries.
And here’s one more plus: uPVC is really low maintenance!
A brief wipe down with soapy water is all it needs to keep your uPVC windows appearing as good as new.
Energy performance is where our uPVC windows genuinely stand out. Multi-chambered uPVC design, U-values as low as 0.8 W/m2K on some frames, and a real improvement to the energy performance of your house.
On top of all that, uPVC double glazing is also the most budget-friendly option available.
So you can often install higher-spec glazing and still keep within budget. We also stock glazed uPVC doors too, including uPVC doors, composite doors, and patio doors to match.
For a good chunk of the year, Scotland’s weather is cold, wet, and windy.
With weather like that, the energy efficiency of your windows makes a real difference to what you shell out on heating and how cosy your house feels from day to day!
A window’s thermal efficiency is measured by something called its U-value.
A lower U-value indicates less heat escaping through the glass and frame. Scottish building regulations currently set a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows deliver 1.2 W/m2K, and our premium models can go as low as 0.8 W/m2K! That’s performance at twice the regulatory minimum!
And where does that difference appear? Right on your energy costs!
A-rated energy-efficient windows and doors come with argon gas filled sealed units and low-E glass coatings to push heat back into the room, all while letting natural light through.
If you are switching from old single-glazed sash windows or early double glazing from the 1990s, you should experience a significant reduction in your heating costs within the first winter.
Middleton has its share of double glazing businesses, and most sell basic products. Few, though, rival the quality of the windows and doors fitted by The Advanced Group.

We get asked about triple glazing all the time.
The additional pane of glass in triple glazing helps it to provide improved insulation and improved noise control.
Exposed location. Up a hill. Facing north. Near a busy road or under a flight path. If any of that fits like your property, The Advanced Group is ready to walk you through the advantages of triple glazing.

We completely appreciate that new windows are an significant spend, and paying for them all at once isn’t always feasible.
So we make available 0% APR and up to 4 years of interest free credit. No fuss.
The windows you need, with the cost spread in a way that fits for you. That’s what 0% finance allows.
