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

New Windows Auchterderran
Quality Energy Efficient Double Glazed Windows & Doors




A change in temperature throughout the home. Rising energy bills. Condensation forming on or inside the windows each morning. Ring any bells?
Does that hit home? Your windows are letting you know something’s.
As windows age, they lose their seal.
The gas between the panes seeps away, the rubber gaskets go rigid and contract, and what used to hold the cold out now barely slows it down.
Auchterderran sees its fair share of rain and wind, often more than sunshine. When your windows are past their best, you notice the difference in how warm and cosy your house is.
But don’t worry, The Advanced Group is here to help with more than 38 years of trusted service. Whether it’s new windows for one room or a full house of replacement windows and doors, we’ll help you find the right option and get everything installed the right way.

The obvious ones stand out. Cracked glass, rotten timber frames, handles that don’t fasten the way they should.
Other signs, though, are easier to miss, and by the time you realise, they might have been costing you money for months or even years.

Spotting moisture or fogging between your two panes of glass tells you the sealed unit has given up.
When the seal fails, the argon gas that delivers insulation leaks, and the window loses a considerable chunk of its thermal performance.
Why throw money away on climbing heating bills? Restore your home’s thermal performance with perfectly sealed new windows today.

Try placing your hand near the edges of your window on a windy day. If you feel cold air sneaking through, the seals have broken down.
Sure, draught proofing strips can do something for a while, but they’re just a sticking plaster. The issue only deteriorates as the rubber continues to perishing.

If your windows catch, won’t fasten correctly, or are tough to open, this presents both a safety risk and an insulation problem. Warped frames, worn hinges, and failed mechanisms are all indicators that the window has come to the end of its working life.
Multi-point locking systems far exceed the old single-point catches for safety. Toughened glass gives extra safety.

Did you realise that windows are behind a large proportion of heat loss in any house? They’re the link between your house and the outside world.
Older double glazing is a thing of the past, and the energy ratings will be significantly below what’s on offer now, even if they were a reasonable specification when they were first installed.
Shield your house from high energy costs. New double glazed windows and doors deliver the difference.

Auchterderran properties vary across all forms, and the right window style depends on your building, the room, and how you live in it.
We supply and fit a full choice of double glazed and triple glazed windows and doors, including uPVC casement, sash, tilt and turn, and top hung styles.

The most common window style in the UK. Side-hinged, opening outwards. Practical for ventilation and simple to clean from inside.
Casement windows work with most property styles. Modern builds, traditional houses, everything in between. Available in a wide selection of colours and finishes, including woodgrain effects that give the look of timber without the maintenance or warping fear.

Our sliding sash windows replicate original wooden sash frames. Modern thermal performance and security are included as standard.
The proportions, sight lines, and opening mechanism all stay true to the traditional design, which is great if your property’s in a conservation area or you just want to maintain its character.

Tilt inward at the top for protected ventilation. Turn fully inward on a side hinge for simple cleaning.
For homeowners in upper-floor flats, tilt and turn windows are a practical choice, as cleaning the outside of the glass from a ladder isn’t an option.
Airflow without the security worry of a fully open window. That’s what the tilt feature provides, and it’s particularly valuable for families with young children.
Hinged at the top, opening outward from the bottom. Practical for ventilation and good at keeping rain out.
Often used in bathrooms, kitchens, stairwells, and bay window configurations. Every space where privacy and airflow both are important.

Think of them as full-length windows that open outward, just like French doors. That’s French windows for you.
Pair them up and match them with sidelights, and you can flood a wide opening with glass and natural light. The result is beautiful.

The Advanced Group concentrates in uPVC frame materials for good reasons.
Scotland’s weather doesn’t go easy on your windows, and uPVC is built to withstand it. It’s durable, resistant to rough, windy, wet weather, and unlike timber, it won’t rot the same way.
Low maintenance comes in as standard with uPVC.
Simply wipe it down with soapy water and it can look brand new.
More importantly though, our uPVC windows are seriously energy efficient. With multi-chambered uPVC engineering, some of our frames can reach a U-value as low as 0.8 W/m2K, working to bring back your home’s energy performance.
And you know the better part? uPVC double glazing is also the most affordable option out there!
Higher-specification glazing without blowing the budget? That’s what uPVC offers. We also carry glazed uPVC doors, including uPVC doors, composite doors, and patio doors to go with.
Scotland dishes out cold, wet, and windy weather for a large portion of the year.
That weather means the energy rating of your windows counts. It shapes how much you shell out on heating and how cosy your property feels day to day.
The thermal performance of a window is measured by its U-value.
A lower figure means less heat getting out through the glass and frame. At present, Scottish building regulations set a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows come in at 1.2 W/m2K, and the premium range can get down to as low as 0.8 W/m2K. That’s double glazing and triple glazing working at twice the level of the regulatory minimum.
That improvement is clearly shown on your energy costs.
Argon gas filled sealed units and low-E glass coatings do the heavy lifting in A-rated energy-efficient windows and doors. Heat gets bounced back in. Light still flows through.
Old single-glazed sash windows or 1990s double glazing? Upgrade them, and you could see a real drop in heating spend before the first winter is out.
There are loads of double glazing businesses in Auchterderran selling entry-level products, but not many can come close to the quality of what we fit.

Our trusted installers are often asked about the triple glazing options we carry.
Triple glazing has an extra pane of glass, enabling it to provide better insulation and reduced noise levels.
Exposed location. Up a hill. Facing north. Near a busy road or under a flight path. If any of those sounds like your property, The Advanced Group is ready to guide you through the advantages of triple glazing.

New windows are an investment, and we know that paying for them all at once isn’t always practical.
So we offer 0% APR and up to 4 years of interest free credit. No fuss.
This allows you get the windows you want by spreading the cost of your new windows and doors in a way that suits with your finances.
