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

Quality Energy Efficient Double Glazed Windows & Doors




A change in temperature around the home. Rising bills. Condensation sitting on or inside the windows each morning. Sound familiar?
Ring a bell? Your windows are sending you a signal.
Older windows lose their seal over time.
The gas between the panes seeps out, the rubber gaskets go hard and contract, and what once held back the cold now scarcely makes a difference.
Living in Newcastle, you know that rain and wind sometimes outnumber the sunny days, and tired windows make a real difference to how warm and snug your house feels.
No need to stress about it! The Advanced Group has been helping homeowners for over 38 years. Whether you need new windows for just one room or every room of replacement windows and doors, we’ll help you find the right choice and get it all installed the right way.

Some problems are easy to spot, such as cracked glass, rotten timber frames, and handles that don’t close properly.
Some signs sneak under the radar however, and by the time you spot them, they’ve been steadily costing you money for months or even years.

Moisture or fogging between the two sheets of glass is a classic sign. The sealed unit has broken down.
When the seal fails, the argon gas that provides insulation leaks, and the window loses a significant portion of its thermal performance.
Don’t keep wasting money away on increasing heating prices. Bring back your home’s thermal performance with well sealed new windows.

Try a quick test: hold your hand near the edges of the window on a windy day. If cold air is sneaking through, the seals have broken down.
Draught proofing strips give you time, but they’re a sticking plaster at most. The rubber continues to breaking down, and the problem only worsens.

Jamming windows that won’t lock properly aren’t just frustrating, they’re a safety risk and an insulation concern too. Warped frames, worn hinges, and failed mechanisms all suggest a window that’s come to the end of its working life.
Modern windows come with multi-point locking systems that are significantly more secure than the single-point catches on older frames. Options like toughened glass give extra safety too.

Windows contribute to a large share of heat loss in any house. They are the barrier between you and the outside weather.
Double glazing from the past is exactly that, in the past. The energy ratings fall well below today’s options, even if the original spec was solid at the time.
High energy costs don’t have to be the norm. New double glazed windows and doors work to guard your home and keep those costs down.

Newcastle properties vary across all shapes and sizes, and the right window type depends on your building, the room, and how you use it.
The Advanced Group has a complete lineup of double glazed and triple glazed windows and doors available, including uPVC casement, sash, tilt and turn, and top hung types, all supplied and fitted by our installers.

Possibly the most popular window choice in the UK, casement windows are side-hinged and open outwards, which makes them ideal for ventilation and straightforward to clean from inside.
Perfect for most property types, from modern homes to traditional houses, casement windows come in a wide choice of colours and finishes, including woodgrain effects that recreate the appearance of timber without the maintenance or worry of warping.

Want the look of original wooden sash frames? Our sliding sash windows mirror that traditional style while packing in modern thermal performance and protection.
The proportions, sight lines, and opening mechanism are all made to mirror the traditional style, which is especially valuable if your property is in a conservation area or you wish to keep its personality.

Tilt them inward at the top for secure ventilation. Turn them fully inward on a side hinge for easy cleaning. Two functions, one window.
They’re particularly common in upper-floor flats, where climbing up a ladder to clean the outside of the glass isn’t feasible.
The tilt feature provides airflow without the safety risks associated with a fully open window, which is particularly helpful for families with young children.
Top hung windows are hinged at the top and open outward from the bottom, making them a smart choice for ventilation while helping to keep rain out.
They’re often chosen in bathrooms, kitchens, stairwells, bay window configurations, and other spaces where privacy and airflow are equally valued.

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

We focus in uPVC frame materials. And for good reason.
Scottish weather dishes out the lot at your windows. uPVC is made to handle it, hardwearing, resilient to wild, windy, wet weather, and free from the warping or rot concerns that affect timber frames.
In addition, uPVC offers the benefit of being low maintenance.
Soapy water and a wipe. That’s all it takes to keep uPVC looking good as new.
Quite possibly most importantly, our uPVC windows deliver high levels of energy efficiency. Built with multi-chambered uPVC, some of our frames achieve a U-value as low as 0.8 W/m2K, working to improve energy performance across your home.
And you want to hear the better bit? uPVC double glazing is also the most cost-effective option going!
That allows you can often opt for higher-spec glazing without blowing the budget. We also carry glazed uPVC doors, including uPVC doors, composite doors, and patio doors to go with.
Cold, wet, and windy. That’s Scotland for a fair chunk of the year.
In that type of weather, the energy performance of your windows really influences how much you spend on heating and how cosy your home feels on a daily basis.
Ever heard of U-values? That’s how the thermal efficiency of any window is measured.
The lower the number, the less heat is lost through the glass and frame. Scottish building regulations currently set a maximum U-value of 1.6 W/m2K for replacement windows.
Standard double glazed windows: 1.2 W/m2K. Premium range: as low as 0.8 W/m2K. That’s twice as efficient as the regulatory minimum.
The difference is reflected on your energy bills.
A-rated energy-efficient windows and doors, supplied with argon gas filled sealed units and low-E glass coatings, perform by reflecting heat back into the room while still managing to let light through.
If you’re coming from old single-glazed sash windows or early double glazing from the 1990s, you could see a really clear drop in your heating costs within just the first winter!
A number of double glazing companies in Newcastle sell entry-level products, but not many can match the quality of the windows and doors we fit.

We get asked about triple glazing a lot.
An extra pane of glass. Better insulation. Improved noise control. That’s triple glazing.
Exposed location. Up a hill. Facing north. Near a busy road or under a flight path. If any of that rings true like your property, The Advanced Group is ready to talk you through the advantages of triple glazing.

We know that new windows are an significant spend, and paying for them all at once isn’t always practical.
So we provide 0% APR and up to 4 years of interest free credit. No fuss.
It means you get the windows you deserve and spread the cost of your new windows and doors in a way that fits comfortably for you!
