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

New Windows Dalgety Bay
Quality Energy Efficient Double Glazed Windows & Doors




Noticed a temperature change in your home? Bills on the increase? Or condensation appearing on or inside your windows when you wake up?
If that seems familiar, your windows are telling you a signal.
Old windows drop their seal over time.
The gas between the panes steadily leaks, the rubber gaskets harden and pull back, and what once blocked the cold out now scarcely slows it down.
In Dalgety Bay, where the rain and wind can feel more regular than sunshine, tired windows definitely affect how warm and cosy your house feels.
The Advanced Group is here to make things easier, backed by over 38 years of trusted expertise. 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 ensure everything is installed the right way.

Cracked glass? Rotten timber frames? Handles that don’t close properly? Some signs are pretty obvious.
But other symptoms are less obvious, and by the time you spot them, they’ve already been losing you money for months, maybe even years.

If you can see moisture or fogging between the two sheets of glass, the sealed unit has given way.
When the seal breaks, the argon gas that provides insulation seeps out, and the window loses a big amount of its thermal efficiency.
Don’t throw money away with rising heating costs and make sure to restore your home’s thermal efficiency with perfectly sealed new windows.

A windy day reveals you everything. Place your hand near the edges of the window. Cold air getting through tells you the seals have deteriorated.
Draught proofing strips can help temporarily, but they’re a sticking plaster on a issue that will only get worse as the rubber goes on to degrade.

Windows that catch, won’t fasten right, or refuse to open are both a safety risk and an insulation problem. Warped frames, worn hinges, failed mechanisms. The window has come to the end of its functional life.
Modern windows come with multi-point locking systems that are far ahead of the single-point catches on older frames. Throw in toughened glass, and you’ve got properly stronger safety.

Your windows are where a large proportion of your home’s heat escapes. That thin barrier between you and the outside world counts more than many people think.
Older double glazing is a thing of the past, and the energy ratings will be well below what’s available now, even if they were a good specification when they were first put in.
Protect your house from rising energy bills. New double glazed windows and doors deliver the difference.

Every house in Dalgety Bay is different. The right window type depends on the property, the room, and how you occupy it.
The Advanced Group delivers a full choice of windows and doors in both double glazed and triple glazed specifications, including uPVC casement, sash, tilt and turn, and top hung styles.

Casement windows are probably the UK’s most widely chosen window type! They’re side-hinged, open outwards, and are perfect for ventilation and simple to clean from inside.
Modern house or traditional villa, casement windows complement the lot. A wide range of colours and finishes is available, and the woodgrain effects replicate the look of timber without any of the maintenance or warping fear.

Our sliding sash windows look like original wooden sash frames. Modern thermal efficiency and safety are built in as standard.
The proportions, sight lines, and opening mechanism are all designed to follow the traditional style, which is especially valuable if your property is in a conservation area or you wish to maintain its charm.

Tilt and turn windows tilt inward at the top for secure ventilation, and turn completely inward on a side hinge for easy cleaning.
If you live in an upper-floor flat, these are a fantastic pick because cleaning the outside of the glass from a ladder just isn’t an option.
The tilt feature provides you airflow without the safety worries of a fully open window, which is especially useful for families with young children.
Top hung windows are hinged at the top and open outward from the bottom, making them a practical choice for ventilation while helping to keep rain out.
You’ll often find them in bathrooms, kitchens, stairwells, and bay window arrangements, spaces where both privacy and airflow count.

French windows are full-length windows that open outward, functioning in the same way as French doors.
Paired together, they look wonderfully and can be matched with sidelights to open up a wide opening with glass and natural light.

The Advanced Group specialises in uPVC frame materials, and for some genuinely good reasons!
Scottish weather is brutal. uPVC is built to withstand it. Long-lasting, resilient to harsh, windy, wet weather. No warping or rot concerns like timber.
In addition, uPVC offers the advantage of being low maintenance.
Soapy water and a quick wipe down. That’s all it takes to keep uPVC looking as good as new.
Energy performance is where our uPVC windows genuinely stand out. Multi-chambered uPVC design, U-values as low as 0.8 W/m2K on some frames, and a real boost to the energy efficiency of your home.
And best of all? uPVC double glazing is also the most budget-friendly option.
Premium-grade glazing without blowing the budget? That’s what uPVC offers. We also supply glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.
Scotland is cold, wet, and windy for a large chunk of the year.
In that climate, the energy efficiency of your windows makes a real difference to how much you pay on heating and how pleasant your property feels on a daily basis.
Ever heard of U-values? That’s how the thermal performance of any window is measured.
A lower U-value indicates less heat being lost through the glass and frame. Scottish building regulations currently require a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows deliver 1.2 W/m2K, and our premium models can hit 0.8 W/m2K! That’s double glazing and triple glazing performing at twice the regulatory minimum!
The result? It appears on your energy statements.
A-rated windows and doors. Argon gas filled sealed units. Low-E glass coatings. Heat bounced back in, light still coming 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.
A lot of double glazing firms in Dalgety Bay sell basic products, but not many can rival the standard of the windows and doors we supply.

Our trusted installers welcome talking about triple glazing, and it’s a topic that arises a lot!
An extra pane of glass. Better insulation. Greater noise dampening. That’s triple glazing.
If your property is positioned in an exposed location, up a hill or high above sea level, facing north, or near a busy road or under a flight path, The Advanced Group would be more than happy to guide you through the advantages of triple glazing.

New windows are an big spend, and we know that paying for them all at once isn’t always realistic.
That’s why we have 0% APR and up to 4 years of interest free credit.
It means you can get the windows you need through helping you spread the cost of your new windows and doors in a way that fits for you.
