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




Maybe you’ve felt a drop in temperature around your home. Heating costs rising. Or condensation collecting on or inside your windows every morning.
If that rings familiar, your windows are telling you something.
Older windows shed their seal over time.
The gas between the panes gradually leaks, the rubber gaskets go rigid and pull back, and what used to held the cold out now scarcely holds it back.
Living in Moffat, you get that rain and wind often outnumber the sunny days, and ageing windows make a proper difference to how warm and cosy your home feels.
Over 38 years in the industry, and The Advanced Group is still here, on hand to help. Whether it’s one room or the entire house that needs new windows and doors, we’ll find the right solution and get everything installed properly.

Some faults are obvious. Cracked glass. Rotten timber frames. Handles that won’t fasten correctly.
But then there are the sneakier signs. The ones you overlook until they’ve already been costing you money for months, perhaps years.

If you spot moisture or fogging between the two panes of glass, this is a strong sign that the sealed unit has given way.
The seal fails. The argon gas leaks out. The window loses a significant portion of its thermal performance.
Climbing heating prices don’t have to keep eating into your pocket. Perfectly sealed new windows will recover your home’s thermal performance and start to push those bills back down.

A windy day reveals you everything. Place your hand near the edges of the window. Cold air sneaking through tells you the seals have deteriorated.
Draught proofing strips? They’re a short-term fix. The fault only gets worse as the rubber keeps perish.

Windows that jam, won’t close correctly, or refuse to budge are both a safety risk and an insulation issue. Warped frames, worn hinges, failed mechanisms. The window has come to the end of its useful life.
Multi-point locking systems on modern windows deliver far stronger security than the single-point catches found on older windows, and toughened glass choices provide an further layer of safety.
Windows leak a large amount of your home’s heat. They’re the bridge between you and the outside world.
Double glazing from the past is exactly that, in the past. The energy ratings land significantly below modern offerings, even if the original spec was decent back then.
New double glazed windows and doors will shield your home from high energy bills.

Every Moffat home has its own character. The right window style comes down to the house, the room, and how you use it.
A full selection 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 types, all supplied and fitted by our installers.

The casement window takes the title of the UK’s most popular style. Side-hinged and opening outwards, they’re great for ventilation and a breeze to clean from inside.
Casement windows match just about any property style, whether it’s a modern home or a traditional property! They are offered in a huge selection of colours and finishes, and the woodgrain effects mimic real timber without the maintenance or warping risk.

Our sliding sash windows replicate original wooden sash frames. Modern thermal efficiency and protection are built in as standard.
Proportions, sight lines, and opening mechanism all match the traditional style. Great for conservation areas or maintaining your property’s character.

Tilt them inward at the top for safe ventilation. Turn them fully inward on a side hinge for simple cleaning. Two modes, one window.
For homeowners in upper-floor flats, tilt and turn windows are a wise choice, as cleaning the outside of the glass from a ladder is not realistic.
The tilt mode delivers airflow without safety concerns. Especially useful for families with young children.
Top hung windows hinge at the top and open outward from the bottom. This makes them a practical choice for ventilation while helping to keep rain out.
Bathrooms, kitchens, stairwells, bay window arrangements, anywhere privacy and airflow both are needed. That’s where top hung windows work best.

Full-length windows that open outward like French doors. That’s exactly what French windows deliver.
Pair them up and match them with sidelights, and you can fill a wide opening with glass and natural light. The effect is beautiful.
There are solid reasons why The Advanced Group focuses in uPVC frame materials.
Scottish weather is demanding, and uPVC is designed to be durable and tough to harsh, windy, and wet weather. Unlike timber frames, uPVC won’t have the same warping or rot concerns.
Not only that, but uPVC is low maintenance.
Just grab it a wipe with soapy water and it’ll look fresh.
Energy efficiency is where our uPVC windows truly shine. Multi-chambered uPVC design, U-values as low as 0.8 W/m2K on some frames, and a proper boost to the energy efficiency of your house.
Better of all? uPVC double glazing is the most cost-effective option.
Higher-spec glazing without blowing the budget? That’s what uPVC makes. We also carry glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.
For a significant part of the year, Scotland’s weather is cold, wet, and windy.
In that type of weather, the energy efficiency of your windows really affects how much you spend on heating and how cosy your house feels day to day.
Thermal performance is measured by U-value.
A lower number means less heat getting out through the glass and frame. Right now, Scottish building regulations require a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows reach 1.2 W/m2K, and our premium options can achieve values as low as 0.8 W/m2K. That’s superior double glazing and triple glazing that performs twice as well as the regulatory minimum.
The difference turns up on your energy costs.
Argon gas filled sealed units and low-E glass coatings do the hard work in A-rated energy-efficient windows and doors. Heat gets reflected back in. Light still comes through.
If you’re replacing old single-glazed sash windows or dated double glazing, you could spot a real drop in your heating spend within the first winter.
Moffat has a good number of double glazing firms. Few match the quality of our windows and doors.

We get asked about triple glazing a lot.
Triple glazing has an extra pane of glass, helping it to offer improved insulation and reduced noise control.
If your house is in an exposed location, up a hill, facing north, or near a busy road or flight path, The Advanced Group is more than glad to walk you through the upsides of triple glazing.

We totally appreciate that new windows are an big purchase, and paying for everything at once isn’t always realistic.
To support with this, we provide 0% APR and up to 4 years of interest free credit.
It means you get the windows you need and spread the cost of your new windows and doors in a way that works nicely for you!
