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

If you’ve spotted a temperature change in your home, or seen your bills rising, or condensation gathering on or inside your windows in the morning, it’s worth taking notice.
If any of that feels familiar, your windows are trying to tell you something.
Older windows lose their seal over time.
Between the panes, the gas seeps away. The rubber gaskets go stiff and contract. What used to kept the cold out now hardly slows it down.
In a city like Holywood, where rain and wind are often more regular than sunshine, tired windows have a noticeable impact on how warm and comfortable your house feels.
No need to panic about it! The Advanced Group has been doing this for over 38 years. Whether you want new windows for just one room or every room of replacement windows and doors, we’ll match you with the right option and get it all installed properly.

Certain signs are hard to miss. Cracked glass, rotten timber frames, handles that won’t close correctly.
Some signs slip under the radar however, and by the time you spot them, they’ve been silently costing you money for months or even years.

Moisture or fogging between the two sheets of glass? The sealed unit has failed.
When the seal fails, the argon gas that provides insulation leaks, and the window loses a big amount of its thermal ability.
Increasing heating costs don’t have to keep going up. Perfectly sealed new windows will recover your home’s thermal efficiency and start to pull those bills back down.

Hold your hand near the edges of the window on a windy day. If you can feel cold air getting in, the seals have deteriorated.
Draught proofing strips can help in the short term, but they’re a sticking plaster on a fault that will only deteriorate as the rubber keeps on break down.

Got windows that seize, won’t lock properly, or just refuse to play along? That’s a security risk and an insulation concern combined. Warped frames, worn hinges, and failed mechanisms all tell you the window has come to the end of its working life.
The single-point catches on older windows can’t match up with the multi-point locking systems on modern ones. Add toughened glass, and your house has a serious protection improvement.
A considerable proportion of heat loss in any house occurs through the windows. They represent the bridge between your indoor space and the outside world.
Double glazing from the past is exactly that, in the past. The energy ratings sit far below today’s offerings, even if the original specification was reasonable at the time.
Guard your home from high energy bills with new double glazed windows and doors.

Every Holywood home has its own feel. The right window style hinges on the building, the room, and how you use it.
A full range of windows and doors, double glazed and triple glazed, is available from The Advanced Group, including uPVC casement, sash, tilt and turn, and top hung designs, all provided and installed by our installers.

Casement windows are probably the UK’s most widely chosen window style! They’re side-hinged, open outwards, and are great for ventilation and simple to clean from inside.
They suit most styles of property, from modern houses to traditional villas, and are available in a wide selection 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, recreated in every detail. That’s what our sliding sash windows deliver, along with modern thermal efficiency and security.
The proportions, sight lines, and opening mechanism match the traditional style. That’s essential if your property is in a conservation area or you just want to maintain its charm.

Tilt and turn windows tilt inward at the top for secure ventilation, and turn fully inward on a side hinge for simple cleaning.
They’re a popular choice for upper-floor flats where cleaning the outside of the glass from a ladder isn’t an option.
The tilt function is a proper bonus! You get airflow without the safety concerns of a fully open window, which is particularly great if you’ve got young children at home.
Hinged at the top, opening outward from the bottom. Sensible 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.

Think of them as full-length windows that open outward, much like French doors. That’s French windows for you.
Pair them up and match them with sidelights, and you can open up a wide opening with glass and natural light. The finish is striking.
The Advanced Group concentrates in uPVC frame materials, and for really good reasons!
Scotland’s weather won’t go easy on your windows, and uPVC is built to handle it. It’s durable, resilient to rough, windy, wet weather, and unlike timber, it won’t warp the same way.
uPVC is low maintenance too.
Just grab it a wipe with soapy water and it’ll look brand new.
Here’s the truly important part: our uPVC windows are highly energy effective! Made with multi-chambered uPVC, some of our frames hit a U-value as low as 0.8 W/m2K, which really helps bring back your home’s energy efficiency.
On top of all that, uPVC double glazing is also the most cost-effective option out there.
Premium-grade glazing without breaking the budget? That’s what uPVC allows. We also carry glazed uPVC doors, including uPVC doors, composite doors, and patio doors to go with.
For a large portion of the year, Scotland’s weather is cold, wet, and windy.
With that climate, your windows’ energy rating genuinely impacts your heating spend and how cosy your house feels daily.
A window’s thermal performance is measured by something called its U-value.
The lower that figure, the less heat is lost through your glass and frame. Scottish building regulations currently require a maximum U-value of 1.6 W/m2K for replacement windows.
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.
The difference shows on your energy bills.
Argon gas filled sealed units and low-E glass coatings do the heavy lifting in A-rated energy-efficient windows and doors. Heat gets reflected back in. Light still flows through.
If you’re switching from old single-glazed sash windows or early double glazing from the 1990s, you could see a noticeable drop in your heating costs within the first winter.
Many double glazing firms in Holywood supply entry-level products, but few can compete with the quality of the windows and doors we fit.

Our trusted installers are often asked about the triple glazing range we offer.
An extra pane of glass. Better insulation. Better noise dampening. That’s triple glazing.
If your house is in an exposed area, up a hill, facing north, or near a busy road or flight path, The Advanced Group is more than willing to walk you through the upsides of triple glazing.

New windows are an big purchase. Paying all at once isn’t always practical. We get that.
So we provide 0% APR and up to 4 years of interest free credit. No fuss.
It means you can get the windows you deserve through helping you spread the cost of your new windows and doors in a way that works for you.
