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

New Windows Gretna
Quality Energy Efficient Double Glazed Windows & Doors




Maybe you’ve felt a drop in temperature inside your house. Heating costs going up. Or condensation collecting on or inside your windows every morning.
If that sounds familiar, your windows are telling you a signal.
The seal on older windows breaks down over time.
The gas between the panes slowly seeps out, the rubber gaskets harden and contract, and what used to held the cold out now scarcely makes any difference.
Living in Gretna, you get that rain and wind sometimes outnumber the sunny days, and worn-out windows make a noticeable difference to how warm and cosy your house feels.
The Advanced Group is here to support you, with over 38 years of trusted expertise. Whether you want 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 ensure everything is fitted properly.

Some faults are plain to see. Cracked glass. Rotten timber frames. Handles that won’t lock right.
But other signs are harder to spot, and by the time you catch them, they’ve already been costing you money for months or even years.

Can you see moisture or fogging trapped between the two sheets of glass? That tells you the sealed unit has given way.
Once the seal has broken, the argon gas responsible for insulation escapes, and the window loses a substantial portion of its thermal performance.
Don’t throw money away with increasing heating prices and make sure to recover your home’s thermal performance with perfectly sealed new windows.

Try placing your hand near the edges of your window on a windy day. If you feel cold air coming through, the seals have worn away.
Draught proofing strips may help in the short term, but they’re only a sticking plaster on a issue that’ll only deteriorate as the rubber keeps degrading.

Sticking windows that won’t close properly aren’t just frustrating, they’re a security risk and an insulation issue too. Warped frames, worn hinges, and failed mechanisms all suggest a window that’s reached the end of its working life.
Multi-point locking systems on today’s windows deliver far stronger protection than the single-point catches found on older frames, and toughened glass options give an additional layer of protection.
Windows lose a considerable amount of your home’s heat. They’re the barrier between you and the outside world.
Old double glazing can’t keep up. The energy ratings are far below what’s possible today, even if the original specification was solid at the time.
High energy costs don’t have to be the norm. New double glazed windows and doors help shield your property and bring those bills down.

Every Gretna property has its own personality. The right window type depends on the building, the room, and how you live in it.
We provide and fit a full choice of double glazed and triple glazed windows and doors, including uPVC casement, sash, tilt and turn, and top hung styles.

Casement windows are probably the most widely chosen window style in the UK. They’re side-hinged and open outwards, making them ideal for ventilation and simple to clean from inside.
They complement most kinds of property, from modern houses to traditional villas, and are available in a wide range of colours and finishes. Woodgrain effects mimic the look of timber without the maintenance or worry of warping.

Our sliding sash windows are made to recreate the appearance of original wooden sash frames, while offering modern levels of thermal efficiency and safety.
The proportions, sight lines, and opening mechanism mirror the traditional look. That’s essential if your property is in a conservation area or you just want to preserve its charm.

Tilt them inward at the top for secure ventilation. Turn them fully inward on a side hinge for simple cleaning. Two options, one window.
If you are in an upper-floor flat, these are a brilliant pick because cleaning the outside of the glass from a ladder just isn’t realistic.
The tilt function provides you airflow without the security concerns of a fully open window, which is particularly handy for families with young children.
Hinged at the top, opening outward from the bottom. Smart for ventilation and great at keeping rain out.
Bathrooms, kitchens, stairwells, bay window arrangements, anywhere privacy and airflow both count. That’s where top hung windows work best.

French windows function just like French doors but are full-length windows that open outward.
Pair them up and match them with sidelights, and you can flood a wide opening with glass and natural light. The finish is beautiful.
The Advanced Group specialises in uPVC frame materials, and for some genuinely good reasons!
Scottish weather is harsh, and uPVC is made to be long-lasting and tough to wild, windy, and wet weather. Unlike timber frames, uPVC won’t have the same warping or rot issues.
Not only that, but uPVC is low maintenance.
Simply wipe it down with soapy water and it can look fresh.
The big advantage? Energy efficiency. Our uPVC windows feature multi-chambered uPVC, and some frames achieve a U-value as low as 0.8 W/m2K. That recovers proper energy performance to your home.
And best of all? uPVC double glazing is also the most budget-friendly option.
That allows you can often choose higher-specification glazing without blowing the budget. We also provide glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.
Scotland’s weather is cold, wet, and windy for a fair chunk of the year.
In such a environment, the energy rating of your windows has a real impact on your heating bills and the overall cosiness of your home day to day.
The thermal performance of any window is measured by its U-value.
The lower that value goes, the less heat escapes. Scottish building regulations set the maximum at 1.6 W/m2K for replacement windows currently.
Standard double glazed windows: 1.2 W/m2K. Premium models: as low as 0.8 W/m2K. That’s twice as good as the regulatory minimum.
You’ll see the difference on your energy bills.
A-rated windows and doors. Argon gas filled sealed units. Low-E glass coatings. Heat bounced back in, light still getting through.
Old single-glazed sash windows or 1990s double glazing? Replace them, and you could see a clear drop in heating spend before the first winter is out.
Many double glazing businesses in Gretna sell entry-level products, but few can compete with the calibre of the windows and doors we supply.

Triple glazing is among the most regular topics our trusted installers get.
An extra pane of glass makes triple glazing apart. It delivers stronger insulation and improved noise dampening over standard double glazing.
If your property is positioned in an exposed location, up a hill or high above sea level, facing north, or near a busy road or under a flight path, The Advanced Group would be more than glad to guide you through the advantages of triple glazing.

New windows are an big spend, and we appreciate that paying for them all at once isn’t always realistic.
That’s why we offer 0% APR and up to 4 years of interest free credit.
This enables you to obtain the windows you need while spreading the cost of your new windows and doors in a way that works for your finances.
