We’ve installed thousands of windows over the last 34 years, take a look at what we have installed more recently.
Fitting Scotland Perfectly
New Windows Summerhill
Quality Energy Efficient Double Glazed Windows & Doors




Spotted a temperature drop in your home? Energy costs on the up? Or condensation sitting on or inside your windows first thing?
That nagging feeling? It’s your windows signalling to you they’re past their best.
Over time, older windows gradually lose their seal.
The gas between the panes leaks out, the rubber gaskets harden and contract, and what used to blocked the cold now hardly does anything.
In Summerhill, where the rain and wind can feel more common than sunshine, tired windows truly change how warm and comfortable your home feels.
The Advanced Group is here to make things easier, with over 38 years of trusted experience. Whether you need new windows for a single room or a full house of replacement windows and doors, we’ll help you find the right fit and make sure everything is fitted the right way.

Certain problems are easy to spot. Cracked glass, rotten timber frames, handles that won’t fasten correctly.
But then there are the quieter signs. The ones you miss until they’ve already been costing you money for months, maybe years.

Moisture or fogging between the two sheets of glass is a dead giveaway sign. The sealed unit has broken down.
The seal goes, and with it leaks the argon gas that provided the insulation. The window loses a significant portion of its thermal ability.
Don’t let rising heating bills eat into your budget. Restore your home’s thermal efficiency by fitting properly sealed new windows.

Here’s a quick test: hold your hand near the edges of the window on a windy day. If cold air is getting through, the seals have broken down.
Draught proofing strips provide a temporary solution, but they’re essentially a sticking plaster on a fault that will only get worse as the rubber continues to break down.

Got windows that stick, won’t fasten right, or just refuse to play along? That’s a security risk and an insulation issue rolled into one. Warped frames, worn hinges, and failed mechanisms all signal you the window has hit the end of its useful life.
Multi-point locking systems on today’s windows deliver significantly greater protection than the single-point catches found on older windows, and toughened glass choices give an additional layer of safety.

Your windows are how a large share of your home’s heat gets out. That thin boundary between you and the outside world makes a difference more than most people expect.
Older double glazing is a thing of the past, and the energy ratings will be significantly below what’s on offer now, even if they were a good specification when they were first fitted.
High energy bills don’t have to be the norm. New double glazed windows and doors help guard your home and keep those bills down.

Every property in Summerhill is different. The right window style depends on the property, the room, and how you live in it.
We supply and install a full range of double glazed and triple glazed windows and doors, including uPVC casement, sash, tilt and turn, and top hung styles.

As quite possibly the most common window style in the UK, casement windows are side-hinged and open outwards, offering effective ventilation and straightforward cleaning from inside.
Perfect for most property styles, from modern builds to traditional villas, casement windows are offered in a wide selection of colours and finishes, including woodgrain effects that replicate the appearance of timber without the maintenance or risk of warping.
The original look of wooden sash frames, mirrored in every detail. That’s what our sliding sash windows provide, along with modern thermal performance and safety.
The proportions, sight lines, and opening mechanism are all made to match the traditional design, which is particularly relevant if your property is in a conservation area or you wish to preserve its character.

These windows give two functions: tilting inward at the top for protected ventilation, and turning completely inward on a side hinge for simple cleaning.
If you are in an upper-floor flat, these are a brilliant option because cleaning the outside of the glass from a ladder just isn’t realistic.
The tilt function provides airflow without security risks. Especially valuable for families with young children.

Hinged at the top, opening outward from the bottom. Smart for ventilation and great at keeping rain out.
You’ll spot top hung windows in bathrooms, kitchens, stairwells, and bay window arrangements, essentially anywhere that privacy and airflow are both needed.

French windows are full-length windows that open outward like French doors.
They’re perfect in pairs and can be paired with sidelights to open up a wide opening with glass and natural light.

The Advanced Group focuses in uPVC frame materials, and for some genuinely good reasons!
Scottish weather is harsh. uPVC is made to withstand it. Hardwearing, resilient to wild, windy, wet conditions. No warping or rot concerns like timber.
Not only that, but uPVC is low maintenance.
A simple wipe down with soapy water is all it needs to keep your uPVC windows looking fresh.
Quite possibly most importantly, our uPVC windows deliver high levels of energy performance. Built with multi-chambered uPVC, some of our frames achieve a U-value as low as 0.8 W/m2K, working to recover energy performance across your property.
And you know the better news? uPVC double glazing is also the most affordable option available!
That allows you can often choose premium-grade glazing without blowing the budget. We also stock glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.
Scotland is cold, wet, and windy for a significant chunk of the year.
In that weather, the energy performance of your windows makes a real difference to how much you spend on heating and how comfortable your house feels day to day.
Know about U-values? That’s how the thermal efficiency of any window is measured.
The lower the value, the less heat escapes through the glass and frame. Scottish building regulations currently demand a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows come in at 1.2 W/m2K. The premium models? As low as 0.8 W/m2K. Twice as good as the regulatory minimum, easily.
The difference shows up 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.
Upgrading from old single-glazed sash windows or 1990s double glazing? Expect a clear drop in heating costs within the first winter.
While many double glazing businesses in Summerhill offer standard products, few can match the quality of the windows and doors we install.
Our experienced installers are regularly asked about our triple glazing options.
Triple glazing adds an extra pane of glass, which delivers stronger insulation and significantly greater noise control.
Exposed area. Up a hill. Facing north. Near a busy road or under a flight path. If any of those rings true like your property, The Advanced Group is here to talk you through the benefits of triple glazing.

We appreciate that new windows are an big purchase, and paying for them all at once isn’t always realistic.
0% APR. Up to 4 years interest free credit. That’s what we offer.
It means you get the windows you deserve and spread the cost of your new windows and doors in a way that works nicely for you!
