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 Green Hill
Quality Energy Efficient Double Glazed Windows & Doors




A shift in temperature throughout the house. Increasing energy bills. Condensation sitting on or inside the windows every morning. Sound familiar?
If that sounds familiar, your windows are telling you a signal.
The seal on older windows deteriorates over time.
The gas between the panes seeps away, the rubber gaskets harden and pull away, and what once did block the cold out now barely slows it down.
In a part of the country like Green Hill, where rain and wind can frequently feel more frequent than the sun, ageing windows make a big difference to how warm and pleasant your home feels.
The Advanced Group is here to support you, with over 38 years of trusted expertise. Whether you want new windows for a single room or a full house of replacement windows and doors, we’ll help you find the right solution and ensure everything is installed properly.

Some faults are obvious. Cracked glass. Rotten timber frames. Handles that won’t lock properly.
But other signs are less obvious, and by the time you spot them, they’ve already been costing you money for months or even years.

If you can see moisture or fogging between the two sheets of glass, this is a sure sign that the sealed unit has failed.
Once that seal breaks, the argon gas that provides insulation leaks out, and your window loses a big amount of its thermal performance.
Climbing heating costs don’t have to keep going up. Well sealed new windows will recover your home’s thermal performance and help bring 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 broken down.
Draught proofing strips offer you time, but they’re a sticking plaster at best. The rubber continues to degrading, and the problem only gets worse.

If your windows catch, won’t lock correctly, or are hard to open, this presents both a safety risk and an insulation concern. Warped frames, worn hinges, and failed mechanisms are all signals that the window has come to the end of its working life.
Modern windows feature multi-point locking systems that are much more safe than the single-point catches on older models. Options like toughened glass add extra security too.

Windows are responsible for a large amount of heat loss in any home. Your window is the barrier between you and the outside weather.
Your old double glazing? It’s outdated! The energy ratings are well below what’s on offer now, even if the original specification was decent when first installed.
New double glazed windows and doors will guard your house from high energy bills.

No two Green Hill houses are the same, and the best window style comes down to on the property, the room, and how you use it.
The Advanced Group offers and fits a full choice of windows and doors in both double glazed and triple glazed options, including uPVC triple and double and triple glazed casement, sash, tilt and turn, and top hung types.

The most common window style in the UK. Side-hinged, opening outwards. Practical for ventilation and easy to clean from inside.
Casement windows fit with most property types. Modern builds, traditional properties, the lot in between. On offer in a wide range of colours and finishes, including woodgrain effects that give the look of timber without the maintenance or warping fear.
Our sliding sash windows mirror original wooden sash frames. Modern thermal performance and security come as standard.
Every proportion, sight line, and opening mechanism follows the traditional design. Whether your property is in a conservation area or you simply want to hold onto its character, these windows do the job.

Tilt inward at the top for protected ventilation. Turn completely inward on a side hinge for easy cleaning.
They’re a popular choice for upper-floor flats where cleaning the outside of the glass from a ladder isn’t practical.
The tilt function provides you airflow without the security risks of a fully open window, which is especially useful for families with young children.

Hinged at the top, swinging outward from the bottom. Top hung windows provide you ventilation and help keep the rain out at the same time.
Bathrooms, kitchens, stairwells, bay window arrangements, anywhere privacy and airflow both are needed. That’s where top hung windows come into their own.

French windows are full-length windows that open outward like French doors.
They perform well in pairs and can be combined with sidelights to fill a wide opening with glass and natural light.

The Advanced Group’s speciality is uPVC frame materials, and this choice is supported by solid reasons.
uPVC frame materials are especially well suited to the demanding Scottish climate, delivering hardwearing performance and resistance to rough, windy, and wet weather. Unlike timber frames, uPVC won’t present the same warping or rot problems.
In addition, uPVC delivers the benefit of being low maintenance.
A quick wipe down with soapy water is all it needs to keep your uPVC windows looking fresh.
Energy efficiency is where our uPVC windows truly shine. Multi-chambered uPVC engineering, U-values as low as 0.8 W/m2K on some frames, and a genuine improvement to the energy performance of your property.
Better of all? uPVC double glazing is the most cost-effective option.
Premium-grade glazing without blowing the budget? That’s what uPVC makes. We also supply glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.
Let’s be straight, Scotland is cold, wet, and windy for a large chunk of the year!
In that weather, the energy rating of your windows makes a genuine difference to how much you shell out on heating and how warm your home feels day to day.
Familiar with U-values? That’s how the thermal efficiency of any window is measured.
The lower that number, the less heat escapes through your glass and frame. Scottish building regulations currently set a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows sit at 1.2 W/m2K. The premium models? As low as 0.8 W/m2K. Twice as good as the regulatory minimum, easily.
That difference is directly visible on your energy costs.
Argon gas filled sealed units and low-E glass coatings do the real work in A-rated energy-efficient windows and doors. Heat gets reflected back in. Light still flows through.
If you are upgrading from old single-glazed sash windows or early double glazing from the 1990s, you may experience a noticeable reduction in your heating costs within the first winter.
There are lots of double glazing firms in Green Hill supplying entry-level products, but not many can match the standard of what we supply.
Our trusted installers love talking about triple glazing, and it’s a question that arises frequently!
Triple glazing has an extra pane of glass, enabling it to provide improved insulation and greater noise control.
If your home 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 walk you through the advantages of triple glazing.

We appreciate that new windows represent a significant investment, and paying for them in full all at once isn’t always realistic.
To help with this, we have available 0% APR and up to 4 years of interest free credit.
It means you get the windows you need and spread the cost of your new windows and doors in a way that suits comfortably for you!
