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

New Windows St Anns
Quality Energy Efficient Double Glazed Windows & Doors




Noticed a temperature shift in your home? Energy costs on the up? Or condensation appearing on or inside your windows when you wake up?
That nagging feeling? It’s your windows telling you something.
Over time, older windows gradually lose their seal.
The gas between the panes seeps out, the rubber gaskets stiffen and shrink, and what used to blocked the cold now hardly slows it down.
Living in St Anns, you know that rain and wind often outnumber the sunny days, and ageing windows make a noticeable difference to how warm and comfortable your home feels.
Not to worry. The Advanced Group has over 38 years of trusted expertise. Single room or full house, replacement windows or doors, we’ll find the right solution and install everything right.

Some faults are obvious. Cracked glass. Rotten timber frames. Handles that won’t lock right.
Other symptoms, though, are less obvious, and by the time you spot, they might have been costing you money for months or even years.

Can you see moisture or fogging sitting between the two sheets of glass? That tells you the sealed unit has failed.
The seal goes. The argon gas seeps out. The window loses a large portion of its thermal performance.
Don’t let climbing heating costs eat into your budget. Bring back your home’s thermal performance by choosing perfectly sealed new windows.

A windy day reveals you everything. Hold your hand near the edges of the window. Cold air sneaking through tells you the seals have deteriorated.
Draught proofing strips give you time, but they’re a sticking plaster at best. The rubber keeps degrading, and the issue only worsens.

Got windows that stick, won’t close right, or just refuse to play along? That’s a safety risk and an insulation issue rolled into one. Warped frames, worn hinges, and failed mechanisms all tell you the window has reached the end of its working life.
Modern windows feature multi-point locking systems that are miles ahead of the single-point catches on older frames. Throw in toughened glass, and you’ve got seriously improved protection.
Your windows are responsible for a considerable amount of the heat loss in your home. They’re the bridge between you and the outside world.
Your old double glazing? It’s a thing of the past! The energy ratings are far below what’s available now, even if the original spec was good back then.
Fitting new double glazed windows and doors is one of the best ways to protect your house from high energy bills.

Every property in St Anns is different. The right window type depends on the house, the room, and how you live in it.
The Advanced Group stocks and fits a complete selection of windows and doors in double glazed and triple glazed options, including uPVC casement, sash, tilt and turn, and top hung types.

The most common window style in the UK. Side-hinged, opening outwards. Great for ventilation and easy to clean from inside.
Casement windows work with most property types. Modern builds, traditional properties, everything in between. On offer in a wide selection of colours and finishes, including woodgrain effects that deliver the look of timber without the maintenance or warping risk.

Our sliding sash windows replicate original wooden sash frames. Modern thermal performance and security are included as standard.
The proportions, sight lines, and opening mechanism all follow the traditional look, which matters if your property is in a conservation area or you simply want to maintain its charm.

Tilt them inward at the top for secure ventilation. Turn them fully inward on a side hinge for simple cleaning. Two modes, one window.
Popular in upper-floor flats. Cleaning the outside from a ladder? Not an option.
The tilt function lets air in without the safety worries of having the window wide open, which is especially valuable if you’ve got young children.
Top hung windows are hinged at the top and open outward from the bottom, providing a sensible option for ventilation that also helps to keep rain out.
Bathrooms, kitchens, stairwells, bay window configurations, anywhere privacy and airflow both are needed. 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 in a nutshell.
Great in pairs. Combine them with sidelights to fill a wide opening with glass and natural light.
The Advanced Group concentrates in uPVC frame materials for sound reasons.
Scottish weather is unforgiving, and uPVC is designed to be hardwearing and resilient to rough, windy, and wet weather. Unlike timber frames, uPVC won’t have the same warping or rot concerns.
Better still, uPVC is incredibly low maintenance.
Simply wipe it down with soapy water and it can look fresh.
Quite possibly most significantly, our uPVC windows offer high levels of energy efficiency. Built with multi-chambered uPVC, some of our frames achieve a U-value as low as 0.8 W/m2K, helping to bring back energy performance in your property.
And the best news? uPVC double glazing happens to be the most cost-effective option on the market.
This allows you to often choose premium-grade glazing without breaking your budget. We also offer glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.
Scotland’s weather is cold, wet, and windy for a fair part of the year.
In that weather, the energy performance of your windows makes a genuine difference to how much you spend on heating and how cosy your house feels on a daily basis.
Thermal efficiency is measured by U-value.
A lower number means less heat being lost through the glass and frame. Currently, Scottish building regulations 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, and our premium range can reach 0.8 W/m2K! That’s performance at twice the regulatory minimum!
The difference is reflected on your energy bills.
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 comes through.
Switching from old single-glazed sash windows or 1990s double glazing? You could see a real drop in heating bills within the first winter.
St Anns has its share of double glazing companies, and most offer entry-level products. Few, though, rival the quality of the windows and doors provided by The Advanced Group.

We get asked about triple glazing a lot.
Triple glazing has an extra pane of glass, enabling it to deliver stronger insulation and improved noise levels.
If your house is in an exposed location, up a hill, facing north, or near a busy road or flight path, The Advanced Group is more than happy to guide you through the upsides of triple glazing.

We fully get that new windows are an big purchase, and paying for everything at once isn’t always practical.
That’s precisely why we have available 0% APR and up to 4 years of interest free credit.
This lets you get the windows you deserve by spreading the cost of your new windows and doors in a way that fits around your budget.
