Perhaps you’ve picked up on a change in temperature in your property. Bills creeping up. Or condensation gathering on or inside your windows in the morning.
If that sounds familiar, your windows are telling you a message.
As windows age, they gradually lose their seal.
The gas between the panes leaks out, the rubber gaskets stiffen and shrink, and what used to hold the cold out now barely slows it down.
In a location like Clifton, where rain and wind are sometimes more regular than sunshine, tired windows have a real impact on how warm and comfortable your house feels.
The Advanced Group is here to support you, with over 38 years of trusted experience. Whether you need new windows for a single room or a full house of replacement windows and doors, we’ll work with you to choose the right fit and make sure everything is installed correctly.

Cracked glass? Rotten timber frames? Handles that don’t fasten properly? Some problems are easy to spot.
Other signs are harder to notice. By the time you do, they’ve been losing you money for months or years.

Moisture or fogging between the two sheets of glass is a classic sign. The sealed unit has broken down.
Once the seal breaks, the argon gas that delivers insulation escapes, and the window loses a significant portion of its thermal performance.
Why waste money away on rising heating bills? Bring back your home’s thermal efficiency with properly sealed new windows today.

On a windy day, hold your hand near the edges of the window. If you can feel cold air coming through, this tells you the seals have worn away.
Sure, draught proofing strips can do something for a bit, but they’re really a sticking plaster. The problem only worsens as the rubber keeps breaking down.

Windows that jam, won’t close right, or refuse to budge are both a safety risk and an insulation problem. Warped frames, worn hinges, failed mechanisms. The window has hit the end of its functional life.
Modern windows have multi-point locking systems that are far more safe than the single-point catches on older frames. Options like toughened glass add extra protection too.
Windows lose a large share of your home’s heat. They’re the bridge between you and the outside elements.
Double glazing from years ago is old news, and the energy ratings will be far below what’s on offer today, even if the spec was decent when first installed.
High energy costs don’t have to be the norm. New double glazed windows and doors help shield your property and keep those costs down.

Clifton properties vary across all forms, and the right window style depends on your building, the room, and how you occupy it.
The Advanced Group provides and fits a full choice of windows and doors in double glazed and triple glazed options, including uPVC casement, sash, tilt and turn, and top hung styles.

As perhaps the most common window type in the UK, casement windows are side-hinged and open outwards, giving good ventilation and simple cleaning from inside.
Ideal for most property kinds, from modern houses to traditional properties, casement windows come in a wide selection of colours and finishes, including woodgrain effects that mimic the appearance of timber without the maintenance or risk of warping.

Love the appearance of original wooden sash frames? Our sliding sash windows mirror that original appearance while packing in modern thermal efficiency and security.
The proportions, sight lines, and opening mechanism mirror the traditional look. That’s key if your property is in a conservation area or you just want to keep its character.

These windows tilt inward at the top for safe ventilation and turn completely inward on a side hinge for simple cleaning.
They’re a well-liked choice for upper-floor flats where cleaning the outside of the glass from a ladder isn’t feasible.
Airflow without the safety concern of a fully open window. That’s what the tilt function gives, and it’s especially handy for families with young children.
Hinged at the top, opening outward from the bottom. Sensible for ventilation and effective at keeping rain out.
Bathrooms, kitchens, stairwells, bay window configurations, anywhere privacy and airflow both count. That’s where top hung windows come into their own.

French windows are full-length panels that open outward much like French doors.
Perfect in pairs. Pair them with sidelights to open up a wide opening with glass and natural light.
The Advanced Group concentrates in uPVC frame materials, and for some genuinely good reasons!
Scottish weather can be rough, but uPVC withstands it all! It’s hardwearing, stands up to wind, rain, and the harshest of it, and you won’t get the warping or rot issues that timber frames suffer from.
On top of that, uPVC is really low maintenance.
Soapy water and a quick wipe down. That’s all it takes to get uPVC looking fresh.
Energy performance is where our uPVC windows really stand out. Multi-chambered uPVC engineering, U-values as low as 0.8 W/m2K on some frames, and a real improvement to the energy efficiency of your house.
And you want to hear the better part? uPVC double glazing is also the most affordable option available!
Premium-grade glazing without exceeding the budget? That’s what uPVC allows. We also carry glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.
For a large portion of the year, Scotland’s weather is cold, wet, and windy.
In that type of climate, the energy efficiency of your windows truly affects how much you pay on heating and how comfortable your house feels day to day.
Thermal efficiency is measured by U-value.
Lower number, less heat lost. Scottish building regulations currently demand a maximum of 1.6 W/m2K for replacement windows.
Our standard double glazed windows deliver 1.2 W/m2K, and our premium range can go as low as 0.8 W/m2K! That’s performance at twice the regulatory minimum!
The difference turns up on your energy bills.
A-rated energy-efficient windows and doors, supplied with argon gas filled sealed units and low-E glass coatings, function by reflecting heat back into the room while still managing to let light through.
Moving from old single-glazed sash windows or 1990s double glazing? You could see a noticeable drop in heating bills within the first winter.
While many double glazing firms in Clifton supply entry-level products, few can rival the calibre of the windows and doors we provide.

Our experienced installers love chatting about triple glazing, and it’s a topic that pops up regularly!
Triple glazing has an extra pane of glass, helping it to deliver enhanced insulation and better noise reduction.
Exposed area? Up a hill? Facing north? Near a busy road or flight path? The Advanced Group will guide you through the advantages of triple glazing.

We understand that new windows represent a notable investment, and paying for them in full all at once isn’t always possible.
To assist with this, we offer 0% APR and up to 4 years of interest free credit.
This allows you get the windows you need by spreading the cost of your new windows and doors in a way that suits with your finances.
