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

Quality Energy Efficient Double Glazed Windows & Doors




If you’ve noticed a temperature change in your house, or spotted your energy bills climbing, or condensation appearing on or inside your windows in the morning, it’s worth taking notice.
Sound familiar? Your windows are telling you a signal.
Old windows lose their seal over time.
The gas between the panes escapes out, the rubber gaskets go hard and pull back, and what used to held back the cold now barely slows it down.
In a city like Kirriemuir, where rain and wind can sometimes feel more common than the sun, tired windows make a big difference to how warm and cosy your home feels.
The Advanced Group is here to support you, 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 solution and make sure everything is installed correctly.

Some faults are hard to miss. Cracked glass. Rotten timber frames. Handles that won’t fasten right.
Other issues, however, are less obvious, and by the time you realise, they might have been losing you money for months or even years.

Seeing moisture or fogging between your two panes of glass indicates the sealed unit has failed.
Once that seal goes, the argon gas that delivers insulation leaks out, and your window loses a big chunk of its thermal performance.
Quit throwing money away on climbing heating costs. Bring back your home’s thermal efficiency with properly sealed new windows.

A windy day reveals you a lot. Put your hand near the edges of the window. Cold air coming through tells you the seals have worn away.
Draught proofing strips? They’re a temporary fix. The fault only deteriorates as the rubber continues to perish.

If your windows stick, won’t close properly, or are tough to operate, this poses both a security risk and an insulation concern. Warped frames, worn hinges, and failed mechanisms are all indicators that the window has reached the end of its functional life.
Modern windows have multi-point locking systems that are much more safe than the single-point catches on older windows. Options like toughened glass provide additional protection too.

Windows contribute to a large proportion of heat loss in any home. Your window is the bridge between you and the outside weather.
Older double glazing is a thing of the past, and the energy ratings will be far below what’s available now, even if they were a reasonable specification when they were first fitted.
High energy costs don’t have to be the standard. New double glazed windows and doors work to shield your home and pull those bills down.

Kirriemuir properties vary across all forms, and the right window type depends on your property, the room, and how you live in it.
We stock and install a full selection of double glazed and triple glazed windows and doors, including uPVC casement, sash, tilt and turn, and top hung types.

The most popular window style in the UK. Side-hinged, opening outwards. Ideal for ventilation and simple to clean from inside.
Casement windows suit most property types, from modern homes to traditional properties, and are offered in a wide selection of colours and finishes, including woodgrain effects that recreate the look of timber without the maintenance and risk of warping.

Our sliding sash windows replicate original wooden sash frames. Modern thermal efficiency and safety are included as standard.
Every proportion, sight line, and opening mechanism mirrors the traditional look. Whether your property sits in a conservation area or you simply want to maintain its charm, these windows do the job.

Tilt and turn windows tilt inward at the top for secure ventilation, and turn completely inward on a side hinge for simple cleaning.
If you are in an upper-floor flat, these are a brilliant pick because cleaning the outside of the glass from a ladder just isn’t practical.
The tilt function is a proper benefit! You get airflow without the security risks of a fully open window, which is especially great if you’ve got young kids at home.
Top hung windows are hinged at the top and open outward from the bottom. This makes them a practical choice for ventilation while helping to keep rain from getting in.
They’re often installed in bathrooms, kitchens, stairwells, bay window arrangements, and other spaces where privacy and airflow are just as important.

French windows are full-length windows that open outward like French doors.
Paired together, they perform brilliantly 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 for good reasons.
Scottish weather can be brutal, but uPVC withstands it all! It’s hardwearing, resists wind, rain, and the worst of it, and you won’t get the warping or rot problems that timber frames suffer from.
Beyond that, uPVC offers the benefit of being low maintenance.
A quick wipe down with soapy water is all it needs to keep your uPVC windows appearing brand new.
The main advantage? Energy efficiency. Our uPVC windows use multi-chambered uPVC, and some frames hit a U-value as low as 0.8 W/m2K. That brings back genuine energy performance to your house.
And you want to hear the better news? uPVC double glazing is also the most cost-effective option available!
That allows you can often choose higher-spec glazing without stretching the budget. We also provide glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.
Cold, wet, and windy. That’s Scotland for a large part of the year.
In that weather, the energy rating of your windows makes a real difference to how much you pay on heating and how cosy your property feels every day.
U-value. That’s the number that tells you how well-insulated a window really is.
A lower U-value means less heat getting out through the 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 come in at 1.2 W/m2K, and our premium options can reach 0.8 W/m2K! That’s double glazing and triple glazing performing at twice the regulatory minimum!
You’ll see the difference on your energy bills.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings are fantastic at bouncing heat back into the room while still allowing loads of light through.
If you are replacing from old single-glazed sash windows or early double glazing from the 1990s, you may notice a noticeable drop in your heating bills within the first winter.
While many double glazing companies in Kirriemuir offer entry-level products, few can match the calibre of the windows and doors we supply.

Triple glazing is among the most regular questions our trusted installers receive.
With an extra pane of glass, triple glazing provides improved insulation and better noise reduction.
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 a significant investment, and paying for them in full all at once isn’t always realistic.
That’s why we provide 0% APR and up to 4 years of interest free credit, making the whole thing much less stressful!
The windows you want, with the cost spread in a way that suits for you. That’s what 0% finance allows.
