If you’ve picked up on a temperature shift in your house, or noticed your bills going up, or condensation forming on or inside your windows in the morning, it’s worth taking notice.
If that matches your situation, your windows are giving you a clear signal.
Windows don’t last forever, and older ones shed theirs over time.
The gas between the panes slowly escapes, the rubber gaskets stiffen and pull back, and what once held the cold out now hardly holds it back.
Living in New Mains, you understand that rain and wind can beat the sunny days, and tired windows make a real difference to how warm and cosy your house feels.
But don’t worry, The Advanced Group is here to lend a hand with more than 38 years of trusted service. Whether it’s new windows for one room or a full house of replacement windows and doors, we’ll help you find the right solution and get everything installed correctly.

Certain signs are easy to spot. Cracked glass, rotten timber frames, handles that don’t fasten properly.
Some signs slip under the radar however, and by the time you pick up on them, they’ve been quietly losing you money for months or even years.

If you can notice moisture or fogging between the two sheets of glass, the sealed unit has given way.
When the seal goes, the argon gas that provides insulation leaks, and the window loses a significant amount of its thermal performance.
Why waste money away on increasing heating bills? Bring back your home’s thermal performance with well sealed new windows today.

A windy day tells you everything. Hold your hand near the edges of the window. Cold air sneaking through tells you the seals have deteriorated.
Draught proofing strips? They’re a short-term fix. The issue only gets worse as the rubber continues to degrade.

If your windows catch, won’t close properly, or are hard to open, this creates both a safety risk and an insulation issue. Warped frames, worn hinges, and failed mechanisms are all signals that the window has come to 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. Throw in toughened glass, and your house has a serious security boost.

Your windows are how a considerable proportion of your home’s heat is lost. That thin bridge between you and the outside elements counts more than many people expect.
Double glazing from years ago is outdated, and the energy ratings will be far below what’s achievable now, even if the specification was decent at the time.
Want to guard your house from those high energy costs? New double glazed windows and doors are the way forward.

Every New Mains property has its own character. The right window style hinges on the building, the room, and how you live in it.
We provide and fit a full selection of double glazed and triple glazed windows and doors, including uPVC casement, sash, tilt and turn, and top hung styles.
Casement windows could well be the UK’s most common window style! They’re side-hinged, open outwards, and are great for ventilation and dead easy to clean from inside.
Suitable for most property kinds, from modern builds to traditional villas, casement windows come in a wide selection of colours and finishes, including woodgrain effects that replicate the appearance of timber without the maintenance or risk of warping.

Our sliding sash windows are made to replicate the style of original wooden sash frames, while providing modern standards of thermal performance and protection.
The proportions, sight lines, and opening mechanism all match the traditional style, which is perfect 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 simple cleaning.
For those living in upper-floor flats, tilt and turn windows are a practical choice, as cleaning the outside of the glass from a ladder isn’t an option.
The tilt function is a real benefit! You get airflow without the safety worries of a fully open window, which is particularly useful if you’ve got young children at home.
Top hung windows hinge at the top and open outward from the bottom. This makes them a sensible choice for ventilation while working to stop rain from getting in.
You’ll often find them in bathrooms, kitchens, stairwells, and bay window setups, rooms where both privacy and airflow count.

French windows are full-length windows that open outward like French doors.
Ideal in pairs. Pair them 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 is brutal. uPVC is made to take it. Hardwearing, tough to rough, windy, wet weather. No warping or rot concerns like timber.
And here’s one more benefit: uPVC is incredibly low maintenance!
Simply wipe it down with soapy water and it can look fresh.
Energy efficiency is where our uPVC windows genuinely shine. Multi-chambered uPVC construction, U-values as low as 0.8 W/m2K on some frames, and a proper improvement to the energy efficiency of your house.
The cherry on top? uPVC double glazing is the most cost-effective option available.
That lets you can often step up to higher-spec glazing without busting the budget! We also offer glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.

For a significant portion of the year, Scotland’s weather is cold, wet, and windy.
In that sort of weather, the energy rating of your windows really influences how much you pay on heating and how cosy your house feels day to day.
U-value. That’s the measurement that shows you how thermally efficient a window really is.
The lower that value goes, the less heat is lost. Scottish building regulations set the maximum at 1.6 W/m2K for replacement windows at present.
Our standard double glazed windows deliver 1.2 W/m2K, and our premium options can achieve values as low as 0.8 W/m2K. That’s top-performing double glazing and triple glazing that operates twice as well as the regulatory minimum.
You’ll see the difference on your energy bills.
A-rated energy-efficient windows and doors use argon gas filled sealed units and low-E glass coatings to push heat back into the room, all while allowing natural light through.
If you’re coming from old single-glazed sash windows or early double glazing from the 1990s, you could see a genuinely noticeable drop in your heating spend within even the first winter!
There are lots of double glazing firms in New Mains offering basic products, but not many can match the calibre of what we supply.

Our experienced installers welcome chatting about triple glazing, and it’s a topic that arises a lot!
Triple glazing includes an extra pane of glass, which provides better insulation and clearly better noise dampening.
Exposed spot? Up a hill? Facing north? Near a busy road or flight path? The Advanced Group will talk you through the advantages of triple glazing.

We understand that new windows are a considerable spend, and paying for them in full all at once isn’t always possible.
That’s why we offer 0% APR and up to 4 years of interest free credit.
Get the windows you need. Spread the cost in a way that suits for you.
