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 Northfield
Quality Energy Efficient Double Glazed Windows & Doors




A change in temperature throughout the home. Climbing energy bills. Condensation forming on or inside the windows each morning. Ring any bells?
If that seems familiar, your windows are telling you a signal.
As windows age, they gradually lose their seal.
The gas between the panes steadily leaks, the rubber gaskets harden and contract, and what once blocked the cold out now barely holds it back.
In Northfield, where the rain and wind can appear more frequent than sunshine, tired windows truly affect how warm and comfortable your house feels.
But not to worry, The Advanced Group is here to support you with over 38 years of trusted service. Whether you want new windows for a single room or a full house of replacement windows and doors, we can guide you to the right option and get everything fitted properly.

Some faults are easy to spot. Cracked glass, rotten timber frames, handles that don’t lock correctly.
Other signs are harder to catch. By the time you realise, they’ve been costing you money for months or years.

Seeing moisture or fogging between your two panes of glass tells you the sealed unit has broken down.
The seal breaks. The argon gas seeps out. The window loses a major chunk of its thermal efficiency.
Rising heating costs don’t have to eat into your wallet. Restore your home’s thermal performance with properly sealed new windows.

On a windy day, put your hand near the edges of the window. If you can feel cold air coming through, this tells you the seals have deteriorated.
Sure, draught proofing strips can do something for a bit, but they’re really a sticking plaster. The issue only gets worse as the rubber keeps degrading.

Got windows that seize, won’t fasten right, or just refuse to cooperate? That’s a security risk and an insulation problem combined. Warped frames, worn hinges, and failed mechanisms all signal you the window has reached the end of its useful life.
Modern windows feature multi-point locking systems that are much more safe than the single-point catches on older frames. Options like toughened glass give further protection too.

Windows are responsible for a considerable share of heat loss in any property. They are the barrier between you and the outside elements.
Double glazing from years ago is outdated, and the energy ratings will be well below what’s available today, even if the specification was decent when first installed.
Want to guard your house from those high energy costs? New double glazed windows and doors are the solution.

Northfield houses vary across all shapes and sizes, and the right window type depends on your building, the room, and how you use it.
The Advanced Group supplies and installs a complete selection of windows and doors in double glazed and triple glazed configurations, including uPVC casement, sash, tilt and turn, and top hung designs.

Quite likely the most widely chosen window style in the UK, casement windows are side-hinged and open outwards, which makes them practical for ventilation and simple to clean from inside.
Suitable for most property styles, from modern houses to traditional villas, casement windows are available in a wide range of colours and finishes, including woodgrain effects that replicate the look of timber without the maintenance or risk of warping.
The sliding sash windows we supply mirror the style of original wooden sash frames, while offering modern thermal efficiency and security.
The proportions, sight lines, and opening mechanism all stay true to the traditional look, which is brilliant if your property’s in a conservation area or you just want to maintain its character.

These windows tilt inward at the top for protected ventilation and turn fully inward on a side hinge for easy cleaning.
Upper-floor flat? Cleaning outside glass from a ladder isn’t feasible. Tilt and turn windows solve that challenge completely.
The tilt feature delivers airflow without security worries. Especially helpful for families with young children.

Hinged at the top, opening outward from the bottom. Practical for ventilation and good at keeping rain out.
You’ll see top hung windows in bathrooms, kitchens, stairwells, and bay window arrangements, basically anywhere that privacy and airflow are both important.

French windows are full-length units that open outward, operating similar to French doors.
In pairs, they perform stunning, and you can pair them with sidelights to fill a wide opening with glass and plenty of natural light.

We focus in uPVC frame materials. And for good reason.
Scottish weather can be harsh, but uPVC withstands it all! It’s durable, resists wind, rain, and the harshest of it, and you won’t get the warping or rot issues that timber frames bring.
Additionally, uPVC provides the benefit of being low maintenance.
Soapy water and a wipe. That’s all it takes to keep uPVC looking fresh.
The main benefit? Energy efficiency. Our uPVC windows feature multi-chambered uPVC, and some frames achieve a U-value as low as 0.8 W/m2K. That brings back proper energy performance to your house.
On top of all that, uPVC double glazing is also the most budget-friendly option out there.
That means you can often upgrade to higher-spec glazing without breaking the budget! We also supply glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.
For a large portion of the year, Scotland’s weather is cold, wet, and windy.
That weather means the energy performance of your windows counts. It influences how much you spend on heating and how comfortable your house feels every single day.
U-value. That’s the figure that shows you how thermally efficient a window really is.
Lower value, less heat lost. Scottish building regulations currently set a maximum of 1.6 W/m2K for replacement windows.
Our standard double glazed windows perform at 1.2 W/m2K, and the premium models can get down to 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 clearly shown on your energy costs.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings reflect heat back into the room while still allowing light through.
Old single-glazed sash windows or 1990s double glazing? Switch them, and you could see a significant drop in heating costs before the first winter is done.
Many double glazing firms in Northfield offer standard products, but few can rival the standard of the windows and doors we supply.
Our trusted installers often get asked about our triple glazing options.
An extra pane of glass makes triple glazing apart. It means stronger insulation and better noise control compared to standard double glazing.
Exposed area? Up a hill? Facing north? Near a busy road or flight path? The Advanced Group will walk you through the advantages of triple glazing.

We appreciate that new windows are an big purchase, and paying for them all at once isn’t always practical.
To assist with this, we offer 0% APR and up to 4 years of interest free credit.
