Big Savings On Our Red Hot Summer SALE!




Spotted a temperature drop in your home? Bills on the up? Or condensation sitting on or inside your windows when you wake up?
Does that hit home? Your windows are sending a signal it’s time for a change.
Over time, older windows start to lose their seal.
The gas between the panes steadily seeps out, the rubber gaskets harden and pull back, and what once blocked the cold out now barely makes any difference.
Highfield gets its fair share of rain and wind, sometimes more than sunshine. When your windows are worn, you notice the difference in how warm and comfortable your house is.
No need to worry about it! The Advanced Group has been doing this for over 38 years. Whether you want new windows for just one room or a full set of replacement windows and doors, we’ll help you find the right solution and get it all fitted the right way.

Some problems are obvious. Cracked glass. Rotten timber frames. Handles that don’t close correctly.
But other signs are harder to notice, and by the time you catch them, they’ve probably already been costing you money for months, perhaps even years.

Noticing moisture or fogging between your two sheets of glass means the sealed unit has given up.
Once the seal has failed, the argon gas responsible for insulation escapes, and the window loses a substantial portion of its thermal efficiency.
Why pour money away on increasing heating costs? Restore your home’s thermal performance with well sealed new windows today.

Try putting your hand near the edges of your window on a windy day. If you notice cold air sneaking through, the seals have deteriorated.
Draught proofing strips? They’re a temporary fix. The problem only gets worse as the rubber keeps degrade.

Windows that jam, jam, or won’t fasten properly are a security risk as well as an insulation issue. Warped frames, worn hinges, and failed mechanisms all suggest the window has reached the end of its working life.
Multi-point locking systems on newer windows offer significantly stronger safety than the single-point catches fitted to older frames, and toughened glass options give an additional layer of protection.
Did you realise that windows cause a large share of heat loss in any property? They’re the bridge between your house and the outside elements.
Older double glazing is a thing of the past, and the energy ratings will be significantly below what’s out there now, even if they were a decent specification when they were first installed.
New double glazed windows and doors will protect your house from high energy costs.

Every Highfield property has its own personality. The right window choice comes down to the house, the room, and how you use it.
The Advanced Group supplies and installs a complete range of windows and doors in double glazed and triple glazed options, including uPVC casement, sash, tilt and turn, and top hung designs.

The casement window holds the title of the UK’s most common style. Side-hinged and opening outwards, they’re great for ventilation and a doddle to clean from inside.
Casement windows suit most property types, from modern builds to traditional houses, and are offered in a wide range of colours and finishes, including woodgrain effects that recreate the look of timber without the maintenance and fear of warping.

The traditional look of wooden sash frames, replicated in every detail. That’s what our sliding sash windows deliver, along with modern thermal efficiency and security.
Every proportion, sight line, and opening mechanism mirrors the traditional look. Whether your property sits in a conservation area or you simply want to keep its charm, these windows fit the bill.

Tilt and turn windows tilt inward at the top for safe ventilation, and turn fully inward on a side hinge for straightforward cleaning.
Well-liked in upper-floor flats. Cleaning the outside from a ladder? Not realistic.
The tilt mode offers you airflow without the security worries of a fully open window, which is particularly valuable for families with young children.
Top hung windows are hinged at the top and open outward from the bottom. This makes them a sensible choice for ventilation while helping to keep rain out.
Bathrooms, kitchens, stairwells, bay window configurations, anywhere privacy and airflow both count. That’s where top hung windows really shine.

French windows work just like French doors but are full-length windows that open outward.
Pair them up and combine them with sidelights, and you can open up a wide opening with glass and natural light. The result is striking.
There are sound reasons why The Advanced Group specialises in uPVC frame materials.
Scottish weather dishes out all sorts at your windows. uPVC is designed to take it, hardwearing, resilient to rough, windy, wet weather, and without the warping or rot concerns that plague timber frames.
uPVC is low maintenance too.
Simply wipe it down with soapy water and it can look brand new.
And here’s the really important part: our uPVC windows are properly energy effective! Made with multi-chambered uPVC, some of our frames achieve a U-value as low as 0.8 W/m2K, which really works to bring back your home’s energy performance.
The best part? uPVC double glazing is the most cost-effective option going.
That means you can often upgrade to higher-spec glazing without busting the budget! We also supply glazed uPVC doors, including uPVC doors, composite doors, and patio doors to coordinate.
Let’s be straight, Scotland is cold, wet, and windy for a fair chunk of the year!
That weather means the energy efficiency of your windows makes a difference. It affects how much you shell out on heating and how cosy your house feels day to day.
Know about U-values? That’s how the thermal efficiency of any window is measured.
The lower that number, the less heat gets out through your 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 a U-value of 1.2 W/m2K, while our premium models can achieve values as low as 0.8 W/m2K, performing at twice the level of the regulatory minimum.
You’ll notice the difference on your energy costs.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings send heat back into the room while still allowing light through.
If you’re replacing old single-glazed sash windows or early double glazing, you could notice a noticeable drop in your heating spend within the first winter.
There are plenty of double glazing firms in Highfield selling entry-level products, but not many can match the quality of what we supply.

Triple glazing is among the most regular enquiries our trusted installers get.
Triple glazing has an extra pane of glass, enabling it to provide stronger insulation and better noise control.
If your property is situated in an exposed area, up a hill or high above sea level, facing north, or near a busy road or under a flight path, The Advanced Group would be more than glad to guide you through the benefits of triple glazing.

New windows are an big purchase. Paying all at once isn’t always realistic. We get that.
That’s precisely why we provide 0% APR and up to 4 years of interest free credit.
It means you can get the windows you need through helping you spread the cost of your new windows and doors in a way that fits for you.
