Felt a temperature drop in your house? Bills on the rise? Or condensation forming on or inside your windows in the morning?
If that sounds familiar, your windows are sending you something.
Over time, older windows gradually lose their seal.
Between the panes, the gas leaks. The rubber gaskets stiffen and shrink. What once blocked the chill now hardly does a thing.
Coates’s rain and wind can seem more frequent than the sun. Worn windows make a clear difference to how warm and comfortable your home feels.
No need to stress about it! The Advanced Group has been helping homeowners for over 38 years. Whether you are after new windows for just one room or the whole house of replacement windows and doors, we’ll guide you to the right choice and get it all installed the right way.

Some issues are obvious. Cracked glass, rotten timber frames, handles that don’t lock as they should.
But then there are the sneakier signs. The ones you don’t notice until they’ve already been draining you money for months, possibly years.

Moisture or fogging between the two sheets of glass is a tell-tale sign. The sealed unit has broken down.
The seal goes, and with it goes the argon gas that provided the insulation. The window loses a significant degree of its thermal performance.
Rising heating costs don’t have to eat into your wallet. Bring back your home’s thermal efficiency with properly sealed new windows.

Hold your hand near the window edges on a windy day. Cold air getting through? The seals have deteriorated.
Draught proofing strips can help temporarily, but they’re a sticking plaster on a problem that will only worsen as the rubber continues to break down.

Got windows that stick, won’t lock right, or just refuse to cooperate? That’s a safety risk and an insulation issue rolled into one. Warped frames, worn hinges, and failed mechanisms all signal you the window has come to the end of its useful life.
Multi-point locking systems on today’s windows deliver far stronger safety than the single-point catches fitted to older windows, and toughened glass choices provide an further layer of security.

Did you realise that windows are behind a considerable amount of heat loss in any house? They’re the bridge between your home and the outside world.
Double glazing from the past is exactly that, in the past. The energy ratings sit far below current standards, even if the original spec was reasonable at the time.
Shield your home from high energy bills with new double glazed windows and doors.

Every Coates home has its own character. The right window style comes down to the house, the room, and how you use it.
The Advanced Group supplies and fits a full range of windows and doors in both double glazed and triple glazed options, including uPVC triple and double and triple glazed casement, sash, tilt and turn, and top hung types.
Perhaps the most widely chosen window type in the UK, casement windows are side-hinged and open outwards, which makes them great for ventilation and easy to clean from inside.
Casement windows go with most property styles. Modern homes, traditional villas, everything in between. On offer in a wide choice of colours and finishes, including woodgrain effects that deliver the look of timber without the maintenance or warping worry.

Our sliding sash windows recreate the look of original wooden sash frames while offering modern thermal performance and safety.
Every proportion, sight line, and opening mechanism follows the traditional look. Whether your property sits in a conservation area or you simply want to maintain its charm, these windows deliver.
These windows tilt inward at the top for protected ventilation and turn fully inward on a side hinge for effortless cleaning.
They’re especially well-liked in upper-floor flats, where climbing up a ladder to clean the outside of the glass is not feasible.
The tilt mode delivers airflow without security worries. Especially 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 are commonly chosen in bathrooms, kitchens, stairwells, bay window setups, and other spaces where privacy and airflow are equally important.

French windows are full-length units that open outward just like French doors.
In pairs, they work brilliant, and you can combine them with sidelights to fill a wide opening with glass and lots of natural light.

There are good reasons why The Advanced Group focuses in uPVC frame materials.
Scottish weather throws the lot at your windows. uPVC is designed to withstand it, durable, resilient to harsh, windy, wet weather, and without the warping or rot concerns that affect timber frames.
On top of that, uPVC is also low maintenance.
Just give it a wipe with soapy water and it’ll look fresh.
More importantly though, our uPVC windows are very energy effective. With multi-chambered uPVC engineering, some of our frames can hit a U-value as low as 0.8 W/m2K, helping to improve your home’s energy performance.
And the best bit? uPVC double glazing happens to be the most budget-friendly option out there.
That means you can often opt for higher-spec glazing without stretching the budget. We also stock glazed uPVC doors, including uPVC doors, composite doors, and patio doors to go with.

Cold, wet, and windy. That’s Scotland for a large part of the year.
In that type of climate, the energy rating of your windows genuinely influences how much you pay on heating and how cosy your home feels every day.
A window’s thermal performance is measured by something called its U-value.
Lower figure, less heat escaping. Scottish building regulations currently set a maximum of 1.6 W/m2K for replacement windows.
Our standard double glazed windows reach 1.2 W/m2K, and our premium models can reach values as low as 0.8 W/m2K. That’s high-quality double glazing and triple glazing that performs twice as well as the regulatory minimum.
The difference shows up on your energy bills.
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 letting light through.
Moving from old single-glazed sash windows or 1990s double glazing? You’ll likely notice a clear drop in heating spend within the first winter.
Many double glazing firms in Coates provide entry-level products, but few can rival the calibre of the windows and doors we fit.

Our trusted installers are regularly asked about the triple glazing range we supply.
Triple glazing has an extra pane of glass, helping it to offer enhanced insulation and improved noise levels.
If your house is in an exposed spot, up a hill, facing north, or near a busy road or flight path, The Advanced Group is more than glad to talk you through the upsides of triple glazing.

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