New Windows Stewarton
Quality Energy Efficient Double Glazed Windows & Doors




Maybe you’ve felt a shift in temperature throughout your home. Energy bills climbing. Or condensation collecting on or inside your windows every morning.
If that seems familiar, your windows are telling you something.
Old windows shed their seal as the years pass.
The gas between the panes leaks out, the rubber gaskets harden and pull away, and what used to block the cold out now barely makes a difference.
Stewarton gets its fair share of rain and wind, often more than sunshine. When your windows are tired, you feel the difference in how warm and cosy your house remains.
The Advanced Group is here to make things easier, with over 38 years of trusted service. Whether you are looking for new windows for a single room or a full house of replacement windows and doors, we’ll help you find the right option and make sure everything is installed the right way.

The obvious ones stand out. Cracked glass, rotten timber frames, handles that won’t close the way they should.
But then there are the quieter signs. The ones you overlook until they’ve already been draining you money for months, possibly years.

Noticing moisture or fogging between your two panes of glass tells you the sealed unit has broken down.
The seal fails. The argon gas leaks out. The window loses a large chunk of its thermal efficiency.
Don’t waste money away with increasing heating bills and make sure to recover your home’s thermal performance with properly sealed new windows.

On a windy day, place your hand near the edges of the window. If you can feel cold air flowing through, this means the seals have broken down.
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 continues to perishing.

A window that catches, won’t fasten properly, or struggles to budge is not just an annoyance. It’s a safety risk and an insulation concern. Warped frames, worn hinges, and failed mechanisms are the window’s way of telling you it’s finished.
Multi-point locking systems on modern windows are much more safe than the single-point catches on older windows, and options like toughened glass add additional protection.
Windows leak a large proportion of your home’s heat. They’re the boundary between you and the outside weather.
Old double glazing can’t compete. The energy ratings are well below what’s available today, even if the original spec was solid at the time.
High energy costs don’t have to be the default. New double glazed windows and doors work to protect your property and keep those bills down.

Every Stewarton property is different, and the right window style depends on the property, the room, and how you use it.
The Advanced Group offers a full choice of windows and doors in both double glazed and triple glazed configurations, including uPVC casement, sash, tilt and turn, and top hung types.

Perhaps the most widely chosen window style in the UK, casement windows are side-hinged and open outwards, which makes them great for ventilation and straightforward to clean from inside.
They fit most types of property, from modern houses to traditional villas, and are available in a wide choice of colours and finishes. Woodgrain effects recreate the look of timber without the maintenance or fear of warping.

The original look of wooden sash frames, mirrored in every detail. That’s what our sliding sash windows offer, along with modern thermal performance and safety.
The proportions, sight lines, and opening mechanism all mirror the traditional style, which matters if your property is in a conservation area or you simply want to keep its charm.

These windows give two functions: tilting inward at the top for safe ventilation, and turning fully inward on a side hinge for easy cleaning.
If you live in an upper-floor flat, these are a fantastic option because cleaning the outside of the glass from a ladder just isn’t feasible.
The tilt function offers you airflow without the safety concerns of a fully open window, which is especially valuable for families with young children.
Top hung windows open outward from the bottom while staying hinged at the top, which is great for getting air in without letting rain through.
Bathrooms, kitchens, stairwells, bay window configurations, anywhere privacy and airflow both matter. That’s where top hung windows work best.

French windows look just like French doors but are full-length windows that open outward.
They’re perfect in pairs and can be combined with sidelights to fill a wide opening with glass and natural light.
uPVC frame materials. That’s what The Advanced Group specialises in, and the reasons are sound.
uPVC frame materials are especially well suited to the demanding Scottish climate, providing hardwearing performance and resistance to wild, windy, and wet weather. Unlike timber frames, uPVC won’t present the same warping or rot issues.
Beyond that, uPVC delivers the benefit of being low maintenance.
Simply wipe it down with soapy water and it can look as good as new.
More to the point though, our uPVC windows are very energy effective. With multi-chambered uPVC engineering, some of our frames can reach a U-value as low as 0.8 W/m2K, helping to improve your home’s energy performance.
And better of all? uPVC double glazing is also the most budget-friendly option.
That lets you can often upgrade to premium-grade glazing without busting the budget! We also carry glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.
Scotland dishes out cold, wet, and windy weather for a large part of the year.
In such a weather pattern, the energy performance of your windows has a genuine effect on your heating bills and the overall warmth of your home day to day.
The thermal performance of any window is measured by its U-value.
The lower that value, the less heat gets out through your glass and frame. Scottish building regulations currently require a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows perform at 1.2 W/m2K, and the premium models can reach as low as 0.8 W/m2K. That’s double glazing and triple glazing performing at twice the level of the regulatory minimum.
That difference is directly reflected on your energy bills.
A-rated windows and doors. Argon gas filled sealed units. Low-E glass coatings. Heat pushed back in, light still coming through.
Old single-glazed sash windows or 1990s double glazing? Replace them, and you could see a significant drop in heating costs before the first winter is over.
Many double glazing businesses in Stewarton supply basic products, but few can rival the standard of the windows and doors we supply.

Our skilled installers are frequently asked about our triple glazing range.
The additional pane of glass in triple glazing allows it to provide improved insulation and greater noise dampening.
If your property is perched in an exposed spot, up a hill, facing north, or near a busy road or under a flight path, reach out! The Advanced Group would be more than pleased to talk you through the upsides of triple glazing.
