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

New Windows Largs
Quality Energy Efficient Double Glazed Windows & Doors




If you’ve picked up on a temperature shift in your house, or seen your bills going up, or condensation appearing on or inside your windows in the morning, it’s time paying attention.
If that feels familiar, your windows are telling you something.
Windows don’t keep their seal indefinitely, and older ones shed theirs over time.
That gas between the panes? It leaks out. The rubber gaskets go rigid and shrink. And what once kept keep the cold out barely holds up.
In a place like Largs, where rain and wind can sometimes feel more regular than the sun, worn windows make a big difference to how warm and cosy your house feels.
Over 38 years in the industry, and The Advanced Group is still here, ready to lend a hand. Whether it’s one room or the full house that needs new windows and doors, we’ll find the right fit and have everything fitted just right.

Some issues are obvious. Cracked glass, rotten timber frames, handles that don’t fasten the way they should.
But other signs are harder to notice, and by the time you notice them, they’ve probably already been losing you money for months, perhaps even years.

If you can see moisture or fogging between the two panes of glass, this is a clear sign that the sealed unit has failed.
Once the seal fails, the argon gas that delivers insulation leaks out, and the window loses a considerable amount of its thermal performance.
Climbing heating bills don’t have to keep going up. Perfectly sealed new windows will recover your home’s thermal efficiency and help push those bills back down.

Try putting your hand near the edges of your window on a windy day. If you feel cold air sneaking through, the seals have broken down.
Draught proofing strips provide a short-term fix, but they’re really a sticking plaster on a problem that will only get worse as the rubber keeps break down.

Windows that catch, jam, or won’t lock correctly are a safety risk as well as an insulation issue. Warped frames, worn hinges, and failed mechanisms all indicate the window has hit the end of its useful life.
Modern windows come with multi-point locking systems that are significantly more secure than the single-point catches on older models. Options like toughened glass provide further security too.
Your windows are behind a considerable proportion of the heat loss in your property. They’re the link between you and the weather outside.
If your double glazing is dated, the energy ratings will very likely be significantly below what’s on offer now, even if they were a decent specification when first installed.
Shield your home from rising energy bills. New double glazed windows and doors make the difference.

Every Largs house is different, and the right window choice depends on the house, the room, and how you live in it.
A full selection of windows and doors, double glazed and triple glazed, is ready from The Advanced Group, including uPVC casement, sash, tilt and turn, and top hung types, all supplied and fitted by our installers.

The casement window claims the title of the UK’s most popular style. Side-hinged and opening outwards, they’re great for ventilation and a breeze to clean from inside.
Suitable for most property kinds, from modern houses to traditional properties, casement windows are offered in a wide choice of colours and finishes, including woodgrain effects that replicate the look of timber without the maintenance or fear of warping.

Our sliding sash windows are crafted to recreate the look of original wooden sash frames, while offering modern levels of thermal performance and security.
The proportions, sight lines, and opening mechanism all stay true to the traditional style, which is perfect if your property’s in a conservation area or you just want to maintain 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.
For those living in upper-floor flats, tilt and turn windows are a wise choice, as cleaning the outside of the glass from a ladder is not realistic.
The tilt feature is a proper benefit! You get airflow without the safety worries of a fully open window, which is particularly handy if you’ve got young ones at home.
Top hung windows are hinged at the top and open outward from the bottom, offering a practical solution for ventilation that also helps to keep rain out.
They’re often installed in bathrooms, kitchens, stairwells, bay window arrangements, and other spaces where privacy and airflow are just as important.

French windows are full-length windows that open outward, operating much like French doors.
Pair them up and combine them with sidelights, and you can fill a wide opening with glass and natural light. The result is beautiful.
The Advanced Group specialises in uPVC frame materials for good reasons.
Scottish weather can be wild, but uPVC handles it all! It’s long-lasting, resists wind, rain, and the roughest of it, and you won’t get the warping or rot issues that timber frames suffer from.
uPVC is low maintenance too.
Soapy water and a cloth. That’s all it takes to get uPVC looking as good as new.
Energy efficiency is where our uPVC windows truly stand out. Multi-chambered uPVC construction, U-values as low as 0.8 W/m2K on some frames, and a real difference to the energy efficiency of your home.
And the better part? uPVC double glazing is also the most budget-friendly option available.
That means you can often step up to higher-specification glazing without blowing the budget! We also offer glazed uPVC doors, including uPVC doors, composite doors, and patio doors to coordinate.
Scotland’s weather is cold, wet, and windy for a fair chunk of the year.
In that kind of weather, the energy efficiency of your windows truly affects how much you pay on heating and how warm your house feels 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 require the maximum at 1.6 W/m2K for replacement windows at present.
Standard double glazed windows: 1.2 W/m2K. Premium options: as low as 0.8 W/m2K. That’s twice as effective as the regulatory minimum.
The proof? It lands on your energy costs.
A-rated energy-efficient windows and doors come with argon gas filled sealed units and low-E glass coatings to bounce heat back into the room, all while letting natural light through.
If you’re replacing old single-glazed sash windows or dated double glazing, you could see a clear drop in your heating costs within the first winter.
Many double glazing companies in Largs provide basic products, but few can match the quality of the windows and doors we supply.

Our experienced installers love talking about triple glazing, and it’s a question that pops up frequently!
Triple glazing has an extra pane of glass, enabling it to deliver enhanced insulation and greater noise levels.
If your property is in an exposed area, 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 advantages of triple glazing.

New windows are an investment. Paying all at once isn’t always practical. We know that.
That’s precisely why we have available 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 for you.
