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 Frognal
Quality Energy Efficient Double Glazed Windows & Doors




Spotted a temperature shift in your home? Energy costs on the up? Or condensation forming on or inside your windows first thing?
Sound familiar? Your windows are telling you a clear sign.
Windows don’t stay sealed forever, and older ones drop theirs over time.
The gas between the panes gradually seeps out, the rubber gaskets stiffen and contract, and what once kept the cold out now hardly slows it down.
In a part of the country like Frognal, where rain and wind can frequently feel more frequent than the sun, tired windows make a real difference to how warm and cosy your house feels.
Not to worry. The Advanced Group has over 38 years of trusted experience. Single room or full house, replacement windows or doors, we’ll find the right solution and install everything correctly.

Some issues are hard to miss. Cracked glass, rotten timber frames, handles that won’t close correctly.
Other signs are less easy to catch. By the time you realise, they’ve been losing you money for months or years.

If you notice moisture or fogging between the two sheets of glass, this is a sure sign that the sealed unit has broken down.
Once the seal has broken, the argon gas responsible for insulation leaks, and the window loses a significant portion of its thermal efficiency.
Don’t throw money away with increasing heating prices and make sure to recover your home’s thermal performance with properly sealed new windows.

Try placing your hand near the edges of your window on a windy day. If you notice cold air sneaking through, the seals have deteriorated.
Draught proofing strips can help for a while, but they’re really a sticking plaster on a issue that’ll only deteriorate as the rubber keeps breaking down.

Windows that stick, seize, or won’t close properly are a security risk as well as an insulation concern. Warped frames, worn hinges, and failed mechanisms all point to the window has reached the end of its functional life.
Modern windows feature multi-point locking systems that are way ahead of the single-point catches on older frames. Throw in toughened glass, and you’ve got seriously improved safety.
A significant share of heat loss in any property happens through the windows. They form the bridge between your internal space and the outside elements.
Old double glazing can’t compete. The energy ratings are far below what’s possible now, even if the original spec was solid at the time.
High energy costs don’t have to be the default. New double glazed windows and doors work to guard your house and keep those bills down.

Every house in Frognal is different. The right window choice depends on the property, the room, and how you occupy it.
The Advanced Group supplies and fits a full selection of windows and doors in both double glazed and triple glazed setups, including uPVC triple and double and triple glazed casement, sash, tilt and turn, and top hung designs.

The casement window holds the crown of the UK’s most widely chosen style. Side-hinged and opening outwards, they’re ideal for ventilation and a doddle to clean from inside.
Casement windows work with most property kinds, from modern homes to traditional houses, and are offered in a wide range of colours and finishes, including woodgrain effects that replicate the look of timber without the maintenance and risk of warping.

The classic look of wooden sash frames, mirrored in every detail. That’s what our sliding sash windows provide, along with modern thermal efficiency 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 keep its personality.

These windows tilt inward at the top for safe ventilation and turn fully inward on a side hinge for easy cleaning.
Upper-floor flat? Cleaning outside glass from a ladder isn’t feasible. Tilt and turn windows fix that challenge completely.
The tilt function provides airflow without security risks. Particularly handy for families with young children.
Top hung windows open outward from the bottom while being hinged at the top, which is perfect for letting air in without letting rain through.
They are frequently fitted in bathrooms, kitchens, stairwells, bay window setups, and other spaces where privacy and airflow are equally important.

French windows are full-length windows that open outward like French doors.
They look well in pairs and can be matched with sidelights to fill a wide opening with glass and natural light.
The Advanced Group concentrates in uPVC frame materials for sound reasons.
Scottish weather is brutal. uPVC is made to handle it. Durable, resistant to harsh, windy, wet weather. No warping or rot worries like timber.
What’s more, uPVC is also low maintenance.
Just a simple wipe with soapy water and it can look as good as new!
Perhaps most significantly, our uPVC windows deliver impressive levels of energy performance. Designed with multi-chambered uPVC, some of our frames attain a U-value as low as 0.8 W/m2K, working to recover energy performance across your home.
And the best part? uPVC double glazing is the most cost-effective option on the market.
This means you can often fit higher-spec glazing without blowing the budget. We also stock glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.
For a large chunk of the year, Scotland’s weather is cold, wet, and windy.
With weather like that, the energy rating of your windows makes a noticeable difference to what you spend on heating and how warm your home feels every day!
Ever heard of U-values? That’s how the thermal efficiency of any window is measured.
The lower that number goes, the less heat gets through. Scottish building regulations set the maximum at 1.6 W/m2K for replacement windows right now.
Our standard double glazed windows deliver 1.2 W/m2K, and our premium products can achieve values as low as 0.8 W/m2K. That’s high-quality double glazing and triple glazing that performs twice as well as the regulatory minimum.
The proof? It appears on your energy statements.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings are brilliant at reflecting heat back into the room while still letting lots of light through.
If you’re swapping out old single-glazed sash windows or 1990s double glazing, you could see a noticeable drop in your heating bills within the first winter.
Frognal has no shortage of double glazing businesses. Few come close to the quality of our windows and doors.

Triple glazing is one of the most regular questions our trusted installers get.
An extra pane of glass makes triple glazing apart. It means improved insulation and greater noise dampening beyond standard double glazing.
Exposed location? Up a hill? Facing north? Near a busy road or flight path? The Advanced Group will walk you through the benefits of triple glazing.

New windows are an investment. Paying all at once isn’t always feasible. We get that.
To support with this, we have available 0% APR and up to 4 years of interest free credit.
Get the windows you deserve. Spread the cost in a way that fits for you.
