Fitting Scotland Perfectly
New Windows Inverness
Quality Energy Efficient Double Glazed Windows & Doors




You’ve felt the temperature dropping in your house. Energy bills are up. Condensation gathers on or inside your windows every morning.
Sound familiar? Your windows are sending you a clear sign.
Old windows lose their seal as the years pass.
The gas between the panes seeps out, the rubber gaskets go hard and contract, and what used to blocked the cold now scarcely makes a difference.
In a place like Inverness, where rain and wind are sometimes more common than sunshine, worn windows have a noticeable impact on how warm and pleasant your house feels.
The Advanced Group is here to make things easier, 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 work with you to choose the right solution and make sure everything is fitted correctly.

Some issues are plain to see. Cracked glass. Rotten timber frames. Handles that don’t fasten correctly.
But then there are the sneakier signs. The ones you don’t notice until they’ve already been draining you money for months, perhaps years.

If you can see moisture or fogging between the two sheets of glass, this is a clear sign that the sealed unit has failed.
Once that seal fails, the argon gas that provides insulation seeps out, and your window loses a huge amount of its thermal efficiency.
Don’t let climbing heating costs chip away at your budget. Bring back your home’s thermal efficiency by choosing perfectly sealed new windows.

A windy day tells you all you need to know. Hold your hand near the edges of the window. Cold air coming through means the seals have worn away.
Draught proofing strips can help in the short term, but they’re really a sticking plaster on a problem that’ll only worsen as the rubber continues to breaking down.

Windows that jam, won’t fasten properly, 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 working life.
Multi-point locking systems beat the old single-point catches for safety. Toughened glass provides extra security.

Your windows are responsible for a considerable amount of the heat loss in your property. They’re the barrier between you and the elements.
If your double glazing is dated, the energy ratings will almost always be well below what’s on offer now, even if they were a decent specification when first fitted.
Protect your house from expensive energy costs. New double glazed windows and doors make the difference.

Every Inverness property is different, and the right window style depends on the property, the room, and how you occupy it.
The Advanced Group provides and installs a full selection of windows and doors in both double glazed and triple glazed options, including uPVC triple and double and triple glazed casement, sash, tilt and turn, and top hung styles.

Perhaps the most popular window style in the UK, casement windows are side-hinged and open outwards, which makes them practical for ventilation and easy to clean from inside.
Modern house or traditional villa, casement windows work with the lot. A wide choice of colours and finishes is on offer, and the woodgrain effects mimic the look of timber without any of the maintenance or warping fear.
Our sliding sash windows replicate the look of original wooden sash frames while providing modern thermal efficiency and security.
The proportions, sight lines, and opening mechanism follow the traditional look. That’s key if your property is in a conservation area or you just want to maintain its personality.

These windows tilt inward at the top for protected ventilation and turn fully inward on a side hinge for effortless cleaning.
Upper-floor flat? Cleaning outside glass from a ladder isn’t practical. Tilt and turn windows solve that problem easily.
The tilt feature gives you airflow without the safety risks of a fully open window, which is particularly helpful for families with young children.

Top hung windows are hinged at the top and open outward from the bottom. This makes them a smart choice for ventilation while working to stop rain out.
You’ll find top hung windows in bathrooms, kitchens, stairwells, and bay window setups, essentially anywhere that privacy and airflow are both a priority.

French windows are full-length panels that open outward in the same way as French doors.
Pair them up and match them with sidelights, and you can flood a wide opening with glass and natural light. The effect is striking.

The Advanced Group specialises in uPVC frame materials for strong reasons.
uPVC frame materials are particularly well suited to the tough Scottish weather, providing hardwearing performance and resilience to wild, windy, and wet weather. Unlike timber frames, uPVC won’t suffer from the same warping or rot problems.
Additionally, uPVC delivers the advantage of being low maintenance.
Wipe it down with soapy water. That’s it. Looks good as new.
Quite possibly most importantly, our uPVC windows deliver strong levels of energy efficiency. Designed with multi-chambered uPVC, some of our frames reach a U-value as low as 0.8 W/m2K, working to recover energy performance across your house.
Better of all? uPVC double glazing is the most cost-effective option.
That lets you can often upgrade to higher-specification glazing without blowing the budget! We also carry glazed uPVC doors, including uPVC doors, composite doors, and patio doors to coordinate.
Scotland’s weather is cold, wet, and windy for a fair chunk of the year.
With weather like that, the energy efficiency of your windows makes a real difference to what you shell out on heating and how comfortable your house feels from day to day!
The thermal efficiency of a window is determined by its U-value.
The lower the number, the less heat gets 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 achieve a U-value of 1.2 W/m2K, while our premium options can attain values as low as 0.8 W/m2K, operating at twice the level of the regulatory minimum.
And where does that difference appear? Straight on your energy statements!
A-rated energy-efficient windows and doors, fitted with argon gas filled sealed units and low-E glass coatings, perform by reflecting heat back into the room while still allowing to let light through.
If you’re replacing old single-glazed sash windows or dated double glazing, you could notice a real drop in your heating bills within the first winter.
While many double glazing businesses in Inverness offer standard products, few can match the calibre of the windows and doors we install.
Our trusted installers are frequently asked about our triple glazing range.
Triple glazing has an extra pane of glass, enabling it to provide enhanced insulation and better noise levels.
If your property is situated in an exposed spot, up a hill or high above sea level, facing north, or near a busy road or under a flight path, The Advanced Group would be more than glad to guide you through the benefits of triple glazing.

New windows are an investment. Paying for everything at once? Not always realistic. We know that.
That’s why we offer 0% APR and up to 4 years of interest free credit, to make the whole thing much more manageable!
