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 Strathmartine
Quality Energy Efficient Double Glazed Windows & Doors




You’ve felt the temperature shifting in your home. Energy bills are up. Condensation forms on or inside your windows every morning.
If that rings familiar, your windows are trying to tell you something.
As windows get older, they start to lose their seal.
The gas between the panes seeps out, the rubber gaskets go hard and pull back, and what used to kept the cold now scarcely does anything.
Strathmartine’s rain and wind can feel more regular than the sun. Tired windows make a clear difference to how warm and comfortable your property feels.
Not to worry. The Advanced Group offers over 38 years of trusted expertise. Single room or full house, replacement windows or doors, we’ll find the right option and fit everything correctly.

Some issues are plain to see. Cracked glass. Rotten timber frames. Handles that don’t fasten properly.
Some signs slip under the radar though, and by the time you pick up on them, they’ve been steadily losing you money for months or even years.

Noticing moisture or fogging between your two panes of glass tells you the sealed unit has broken down.
When the seal fails, the argon gas that delivers insulation escapes, and the window loses a significant amount of its thermal efficiency.
Climbing heating prices don’t have to empty your wallet. Bring back your home’s thermal efficiency with perfectly sealed new windows.

Hold your hand near the edges of the window on a windy day. If you can feel cold air getting in, the seals have worn.
Draught proofing strips? They’re a temporary fix. The problem only deteriorates as the rubber keeps break down.

Windows that jam, won’t lock right, or refuse to open are both a safety risk and an insulation problem. Warped frames, worn hinges, failed mechanisms. The window has reached the end of its useful life.
Multi-point locking systems on modern windows provide much better protection than the single-point catches found on older windows, and toughened glass options give an additional layer of protection.

A considerable amount of heat loss in any property happens through the windows. They act as the boundary between your internal space and the outside world.
Old double glazing can’t keep up. The energy ratings are well below what’s on offer today, even if the original specification was solid at the time.
Guard your property from high energy bills with new double glazed windows and doors.

Every Strathmartine property has its own character. The right window choice hinges on the building, the room, and how you occupy it.
A full range of windows and doors, double glazed and triple glazed, is available from The Advanced Group, including uPVC casement, sash, tilt and turn, and top hung designs, all supplied and fitted by our team.

The most widely fitted window type in the UK. Side-hinged, opening outwards. Great for ventilation and simple to clean from inside.
Casement windows work with most property types. Modern houses, traditional villas, everything in between. Available in a wide choice of colours and finishes, including woodgrain effects that deliver the look of timber without the maintenance or warping fear.

The traditional look of wooden sash frames, recreated in every detail. That’s what our sliding sash windows provide, along with modern thermal performance and safety.
The proportions, sight lines, and opening mechanism all match the traditional look, which is perfect if your property’s in a conservation area or you just want to hold onto its character.

Tilt inward at the top for protected ventilation. Turn completely inward on a side hinge for easy cleaning.
If you live in an upper-floor flat, these are a great option because cleaning the outside of the glass from a ladder just isn’t an option.
The tilt mode gives you airflow without the security worries of a fully open window, which is especially valuable for families with young children.
Top hung windows are hinged at the top and open outward from the bottom, making them a sensible choice for ventilation while working to keep rain out.
You’ll spot top hung windows in bathrooms, kitchens, stairwells, and bay window configurations, essentially anywhere that privacy and airflow are both a priority.

French windows are full-length windows that open outward like French doors.
They look well in pairs 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 good reasons.
uPVC frame materials are particularly well suited to the harsh Scottish climate, delivering durability and resistance to wild, windy, and wet weather. Unlike timber frames, uPVC won’t present the same warping or rot concerns.
Not only that, but uPVC is low maintenance.
Simply wipe it down with soapy water and it can look brand new.
More to the point however, our uPVC windows are highly energy efficient. With multi-chambered uPVC engineering, some of our frames can hit a U-value as low as 0.8 W/m2K, working to bring back your home’s energy performance.
Best of all? uPVC double glazing is the most budget-friendly option.
This means you can often choose higher-specification glazing without breaking the budget. We also supply 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 weather means the energy rating of your windows makes a difference. It affects how much you pay on heating and how warm your home feels every single day.
The thermal efficiency of a window is measured by its U-value.
The lower that value, the less heat is lost through your 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 go as low as 0.8 W/m2K! That’s double glazing and triple glazing performing 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 hard work in A-rated energy-efficient windows and doors. Heat gets bounced back in. Light still comes through.
If you’re upgrading from old single-glazed sash windows or 1990s double glazing, you could spot a noticeable drop in your heating spend within the first winter.
While many double glazing firms in Strathmartine offer standard products, few can compare with the calibre of the windows and doors we supply.

Our experienced installers welcome chatting about triple glazing, and it’s a question that comes up regularly!
Triple glazing adds an extra pane of glass, which gives enhanced insulation and clearly improved noise dampening.
Exposed spot? Up a hill? Facing north? Near a busy road or flight path? The Advanced Group will guide you through the advantages of triple glazing.

New windows are an big spend, and we understand that paying for them all at once isn’t always realistic.
That’s why we offer 0% APR and up to 4 years of interest free credit, making the purchase much less stressful!
This lets you get the windows you need by spreading the cost of your new windows and doors in a way that fits around your budget.
