Quality Energy Efficient Double Glazed Windows & Doors




Noticed a temperature shift in your home? Heating bills on the increase? Or condensation sitting on or inside your windows when you wake up?
Does that ring true? Your windows are telling you they need replacing.
As windows wear, they start to lose their seal.
The gas between the panes seeps out, the rubber gaskets stiffen and pull back, and what used to kept the cold now barely slows it down.
Dumfries’s rain and wind can feel more common than the sun. Worn windows make a noticeable difference to how warm and cosy your house feels.
Not to worry. The Advanced Group offers over 38 years of trusted experience. Single room or full house, replacement windows or doors, we’ll find the right solution and install everything correctly.

Some signs are obvious. Cracked glass, rotten timber frames, handles that won’t fasten properly.
But then there are the sneakier signs. The ones you miss until they’ve already been costing you money for months, possibly years.

Can you see moisture or fogging forming between the two sheets of glass? That tells you the sealed unit has failed.
Once the seal breaks, the argon gas that gives insulation seeps away, and the window loses a large amount of its thermal performance.
Quit pouring money away on rising heating bills. Restore your home’s thermal performance with perfectly sealed new windows.

On a windy day, place your hand near the edges of the window. If you can feel cold air coming through, this suggests the seals have worn away.
Draught proofing strips provide a brief solution, but they’re just a sticking plaster on a fault that will only deteriorate as the rubber keeps degrade.

Seizing windows that won’t lock right aren’t just frustrating, they’re a security risk and an insulation issue too. Warped frames, worn hinges, and failed mechanisms all point to a window that’s hit the end of its useful life.
The single-point catches on older windows don’t match up with the multi-point locking systems on modern windows. Throw in toughened glass, and your home gains a real safety improvement.
Windows lose a large share of your home’s heat. They’re the barrier between you and the outside world.
Your old double glazing? It’s had its day! The energy ratings are well below what’s on offer now, even if the original setup was good back then.
Guard your house from high energy bills with new double glazed windows and doors.

No two Dumfries homes are the same, and the ideal window style comes down to on the house, the room, and how you use it.
The Advanced Group provides a full range of windows and doors in both double glazed and triple glazed specifications, including uPVC casement, sash, tilt and turn, and top hung styles.

Casement windows are probably the UK’s most popular window type! They’re side-hinged, open outwards, and are brilliant for ventilation and simple to clean from inside.
Casement windows work with most property types, from modern builds to traditional properties, and are available in a wide selection of colours and finishes, including woodgrain effects that replicate the look of timber without the maintenance and risk of warping.

The sliding sash windows we supply mirror the style of original wooden sash frames, while delivering modern thermal efficiency and protection.
The proportions, sight lines, and opening mechanism all stay true to the traditional style, which is great if your property’s in a conservation area or you just want to maintain its personality.

Tilt inward at the top for safe ventilation. Turn completely inward on a side hinge for quick cleaning.
If you live in an upper-floor flat, these are a fantastic pick because cleaning the outside of the glass from a ladder just isn’t an option.
The tilt function allows air in without the security risks of having the window fully open, which is especially handy if you’ve got young children.
Hinged at the top, swinging outward from the bottom. Top hung windows offer you ventilation and help hold the rain out at the same time.
Frequently fitted in bathrooms, kitchens, stairwells, and bay window arrangements. Every space where privacy and airflow both count.

French windows are full-length windows that open outward just like French doors.
They’re ideal in pairs and can be matched with sidelights to flood a wide opening with glass and natural light.
The Advanced Group focuses in uPVC frame materials for strong reasons.
Scottish weather can be rough, but uPVC takes it all! It’s hardwearing, stands up to wind, rain, and the roughest of it, and you won’t get the warping or rot problems that timber frames come with.
Low maintenance is built in as standard with uPVC.
Just grab it a wipe with soapy water and it’ll look as good as new.
But more to the point, our uPVC windows are highly energy efficient. Designed with multi-chambered uPVC, some of our frames can hit a U-value as low as 0.8 W/m2K, helping bring back energy efficiency to your property.
And you know the better news? uPVC double glazing is also the most budget-friendly option out there!
That means you can often opt for premium-grade glazing without blowing the budget. We also stock glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.
Scotland’s weather is cold, wet, and windy for a good part of the year.
That climate means the energy rating of your windows matters. It affects how much you shell out on heating and how cosy your home feels from one day to the next.
A window’s thermal performance is measured by something called its U-value.
Lower value, less heat lost. Scottish building regulations currently set a maximum of 1.6 W/m2K for replacement windows.
Our standard double glazed windows come in at 1.2 W/m2K, and our premium range can hit 0.8 W/m2K! That’s double glazing and triple glazing performing at twice the regulatory minimum!
And where does that difference show up? Straight on your energy statements!
A-rated energy-efficient windows and doors, fitted with argon gas filled sealed units and low-E glass coatings, function by pushing heat back into the room while continuing to let light through.
Old single-glazed sash windows or 1990s double glazing? Upgrade them, and you could see a noticeable drop in heating bills before the first winter is over.
While many double glazing businesses in Dumfries offer standard products, few can rival the standard of the windows and doors we provide.

Our experienced installers are regularly asked about our triple glazing range.
Triple glazing includes an extra pane of glass, which gives better insulation and noticeably better noise control.
Exposed location? Up a hill? Facing north? Near a busy road or flight path? The Advanced Group will talk you through the advantages of triple glazing.

New windows are an significant spend. Paying for them all at once? Not always feasible. We know that.
To help with this, we provide 0% APR and up to 4 years of interest free credit.
This helps you to install the windows you need while spreading the cost of your new windows and doors in a way that suits your budget.
