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

Felt a temperature drop in your home? Bills on the rise? Or condensation forming on or inside your windows in the morning?
That nagging feeling? It’s your windows signalling to you they’re past their best.
Older windows lose their seal over time.
The gas between the panes seeps away, the rubber gaskets stiffen and pull away, and what once did keep the cold out now barely makes a difference.
Forfar sees its fair share of rain and wind, sometimes more than sunshine. When your windows are worn, you feel the difference in how warm and comfortable your home stays.
Over 38 years in the industry, and The Advanced Group is still here, on hand to lend a hand. Whether it’s one room or the full house that is due new windows and doors, we’ll find the right option and get everything fitted just right.

Some problems are straightforward, like cracked glass, rotten timber frames, and handles that don’t close properly.
Some signs fly under the radar however, and by the time you spot them, they’ve been silently losing you money for months or even years.

If you can see moisture or fogging between the two sheets of glass, the sealed unit has given way.
When the seal fails, the argon gas that acts as insulation escapes, and the window loses a considerable chunk of its thermal ability.
Don’t throw money away with rising heating costs and make sure to bring back your home’s thermal performance with perfectly sealed new windows.

A windy day shows you all you need to know. Place your hand near the edges of the window. Cold air coming through tells you the seals have gone.
Draught proofing strips? They’re a quick fix. The problem only deteriorates as the rubber continues to degrade.

A window that jams, won’t close right, or refuses to open is not just an annoyance. It’s a security risk and an insulation problem. Warped frames, worn hinges, and failed mechanisms are the window’s way of telling you it’s done.
Modern windows come with multi-point locking systems that are significantly more secure than the single-point catches on older models. Options like toughened glass provide extra safety too.

Windows contribute to a large amount of heat loss in any home. They are the bridge between you and the outside world.
Old double glazing can’t compare. The energy ratings are significantly below what’s on offer now, even if the original specification was decent when first fitted.
Choosing new double glazed windows and doors is one of the most effective ways to guard your property from high energy costs.

Forfar properties vary across all shapes and sizes, and the right window style depends on your property, the room, and how you occupy it.
The Advanced Group provides a full range of windows and doors in both double glazed and triple glazed options, including uPVC casement, sash, tilt and turn, and top hung styles.

Casement windows might just be the UK’s most common window style! They’re side-hinged, open outwards, and are perfect for ventilation and simple to clean from inside.
Casement windows complement most property kinds, from modern houses to traditional villas, and are offered in a wide range of colours and finishes, including woodgrain effects that replicate the look of timber without the maintenance and fear of warping.

Our sliding sash windows replicate original wooden sash frames. Modern thermal efficiency and safety are built in 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 preserve its charm.

Tilt inward at the top for safe ventilation. Turn completely inward on a side hinge for simple cleaning.
They’re especially well-liked in upper-floor flats, where climbing up a ladder to clean the outside of the glass is not feasible.
Airflow without the safety concern of a fully open window. That’s what the tilt function provides, and it’s particularly useful for families with young children.
Top hung windows are hinged at the top and open outward from the bottom, giving a sensible solution for ventilation that also helps to keep rain out.
Commonly fitted in bathrooms, kitchens, stairwells, and bay window configurations. Every space where privacy and airflow both are important.

Full-length windows that open outward like French doors. That’s what French windows deliver.
Paired together, they work beautifully and can be combined with sidelights to cover a wide opening with glass and natural light.

The Advanced Group focuses in uPVC frame materials for strong reasons.
Scottish weather is brutal. uPVC is built to take it. Long-lasting, tough to harsh, windy, wet conditions. No warping or rot worries like timber.
Not only that, but uPVC is low maintenance.
Just a quick wipe with soapy water and it looks brand new!
And here’s the really exciting part: our uPVC windows are properly energy effective! Made with multi-chambered uPVC, some of our frames reach a U-value as low as 0.8 W/m2K, which seriously works to boost your home’s energy efficiency.
And you know the best bit? uPVC double glazing is also the most affordable option out there!
This means you can often fit higher-specification glazing without exceeding the budget. We also stock glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.
Cold, wet, and windy. That’s Scotland for a good chunk of the year.
That climate means the energy rating of your windows makes a difference. It shapes how much you pay on heating and how comfortable your home feels day to day.
Know about U-values? That’s how the thermal efficiency of any window is measured.
The lower the figure, the less heat is 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 a U-value of 1.2 W/m2K, while our premium models can attain values as low as 0.8 W/m2K, operating at twice the level of the regulatory minimum.
You’ll notice the difference on your energy costs.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings are amazing at reflecting heat back into the room while still allowing loads of light through.
Upgrading from old single-glazed sash windows or 1990s double glazing? You could see a clear drop in heating spend within the first winter.
While many double glazing companies in Forfar provide basic products, few can match the quality of the windows and doors we provide.

Our trusted installers often get asked about our triple glazing options.
An extra pane of glass. Enhanced insulation. Greater noise dampening. That’s triple glazing.
If your property is in an exposed location, at a raised altitude, facing north, or near a busy road or flight path, The Advanced Group would be more than pleased to guide you through the advantages of triple glazing.

We completely appreciate that new windows are an investment, and paying for everything at once isn’t always doable.
That’s precisely why we offer 0% APR and up to 4 years of interest free credit.
It means you get the windows you deserve and spread the cost of your new windows and doors in a way that suits nicely for you!
