If you’ve noticed a temperature change in your house, or spotted your bills rising, or condensation gathering on or inside your windows in the morning, it’s time taking notice.
If that describes your situation, your windows are giving you a clear signal.
Older windows drop their seal over time.
Gas leaks from between the panes. The rubber gaskets go rigid and contract. What used to hold back the cold now barely makes a difference.
In a city like Glebe, where rain and wind are sometimes more frequent than sunshine, ageing windows have a real effect on how warm and comfortable your home feels.
But don’t worry, The Advanced Group is here to lend a hand with more than 38 years of trusted experience. 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 have everything installed properly.

Some signs are easy to spot. Cracked glass, rotten timber frames, handles that won’t fasten the way they should.
But other symptoms are harder to notice, and by the time you catch them, they’ve already been costing you money for months, perhaps even years.

Moisture or fogging between the two sheets of glass? The sealed unit has failed.
Once that seal breaks, the argon gas that delivers insulation escapes out, and your window loses a significant chunk of its thermal effectiveness.
Don’t pour money away with increasing heating prices and make sure to restore your home’s thermal efficiency with perfectly sealed new windows.

Try placing your hand near the edges of your window on a windy day. If you can feel cold air getting through, the seals have deteriorated.
Draught proofing strips buy you time, but they’re a sticking plaster at most. The rubber keeps breaking down, and the problem only worsens.

Windows that jam, won’t lock properly, or refuse to open are both a security risk and an insulation issue. Warped frames, worn hinges, failed mechanisms. The window has hit the end of its working life.
The single-point catches on older windows can’t compare with the multi-point locking systems on modern frames. Factor in toughened glass, and your house gains a serious security upgrade.

Windows contribute to a significant share of heat loss in any house. Your window is the boundary between you and the outside weather.
Old double glazing can’t keep up. The energy ratings are far below what’s possible now, even if the original spec was good when first fitted.
Guard your house from high energy bills with new double glazed windows and doors.

Every house in Glebe is different. The right window style depends on the building, the room, and how you use it.
The Advanced Group provides and installs a complete range of windows and doors in double glazed and triple glazed configurations, including uPVC casement, sash, tilt and turn, and top hung styles.

Casement windows are quite possibly the most popular window type in the UK. They’re side-hinged and open outwards, making them ideal for ventilation and simple to clean from inside.
Casement windows match just about any property type, whether it’s a modern build or a traditional villa! They are available in a huge choice of colours and finishes, and the woodgrain effects replicate real timber without the maintenance or warping risk.
Our sliding sash windows replicate original wooden sash frames. Modern thermal efficiency and safety are included as standard.
The proportions, sight lines, and opening mechanism all mirror the traditional design, which is great if your property’s in a conservation area or you just want to keep its charm.

Tilt and turn windows are genuinely handy! They tilt inward at the top for protected ventilation and swing completely inward on a side hinge for simple cleaning.
If you are in an upper-floor flat, these are a fantastic option because cleaning the outside of the glass from a ladder just isn’t realistic.
The tilt feature delivers airflow without safety worries. Especially helpful for families with young children.

Top hung windows hinge at the top and open outward from the bottom. This makes them a smart choice for ventilation while working to hold rain out.
You’ll spot top hung windows in bathrooms, kitchens, stairwells, and bay window arrangements, essentially anywhere that privacy and airflow are both important.

French windows are full-length windows that open outward like French doors.
They’re ideal in pairs and can be paired with sidelights to flood a wide opening with glass and natural light.

The Advanced Group specialises in uPVC frame materials for sound reasons.
Scottish weather can be brutal, but uPVC handles it all! It’s durable, resists wind, rain, and the roughest of it, and you won’t get the warping or rot problems that timber frames come with.
uPVC is low maintenance too.
Simply wipe it down with soapy water and it can look good as new.
And here’s the genuinely important part: our uPVC windows are seriously energy efficient! Made with multi-chambered uPVC, some of our frames reach a U-value as low as 0.8 W/m2K, which really helps boost your home’s energy efficiency.
The cherry on top? uPVC double glazing is the most affordable option out there.
Higher-specification glazing without exceeding the budget? That’s what uPVC makes. We also stock glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.
Let’s be straight, Scotland is cold, wet, and windy for a good chunk of the year!
With that climate, your windows’ energy performance genuinely impacts your heating bills and how comfortable your house feels day to day.
The thermal performance of any window is measured by its U-value.
The lower that figure goes, the less heat escapes. Scottish building regulations cap the maximum at 1.6 W/m2K for replacement windows currently.
Our standard double glazed windows reach 1.2 W/m2K, and our premium products can achieve values as low as 0.8 W/m2K. That’s top-performing double glazing and triple glazing that works twice as well as the regulatory minimum.
The difference appears on your energy bills.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings are brilliant at sending heat back into the room while still allowing lots of light through.
If you are replacing from old single-glazed sash windows or early double glazing from the 1990s, you could notice a clear decrease in your heating spend within the first winter.
While many double glazing businesses in Glebe supply standard products, few can rival the standard of the windows and doors we install.
We get asked about triple glazing a lot.
An extra pane of glass. Enhanced insulation. Better noise reduction. That’s triple glazing.
If your property is located in an exposed area, up a hill, facing north, or near a busy road or under a flight path, get in touch! The Advanced Group would be more than pleased to walk you through the upsides of triple glazing.

New windows are an significant spend. Paying all at once isn’t always practical. We understand that.
So we offer 0% APR and up to 4 years of interest free credit. Straightforward.
Get the windows you want. Spread the cost in a way that suits for you.
