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

New Windows Nairn
Quality Energy Efficient Double Glazed Windows & Doors




You’ve spotted the temperature changing in your home. Bills are climbing. Condensation forms on or inside your windows each morning.
If that describes your home, your windows are giving you a sign.
Over time, older windows start to lose their seal.
The gas between the panes steadily seeps out, the rubber gaskets harden and contract, and what once held the cold out now hardly slows it down.
Living in Nairn, you know that rain and wind often outweigh the sunny days, and tired windows make a real difference to how warm and cosy your home feels.
Not to worry. The Advanced Group offers over 38 years of trusted service. Single room or full house, replacement windows or doors, we’ll find the right solution and install everything properly.

Cracked glass? Rotten timber frames? Handles that don’t fasten properly? Some problems are easy to spot.
But other signs are harder to notice, and by the time you spot them, they’ve already been costing you money for months, sometimes even years.

If you can see moisture or fogging between the two sheets of glass, the sealed unit has failed.
Once the seal breaks, the argon gas that gives insulation seeps away, and the window loses a considerable chunk of its thermal performance.
Rising heating bills don’t have to keep going up. Properly sealed new windows will bring back your home’s thermal performance and start to bring those costs back down.

Try putting your hand near the edges of your window on a windy day. If you feel cold air sneaking through, the seals have deteriorated.
Draught proofing strips can help for a while, but they’re only a sticking plaster on a problem that’ll only get worse as the rubber keeps degrading.

A window that catches, won’t fasten right, or refuses to budge is more than an inconvenience. It’s a safety risk and an insulation issue. 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 way ahead of the single-point catches on older frames. Throw in toughened glass, and you’ve got seriously stronger safety.

Windows are responsible for a considerable amount of heat loss in any property. It is the barrier between you and the outside elements.
Old double glazing can’t compare. The energy ratings are far below what’s available today, even if the original specification was solid when first fitted.
Installing new double glazed windows and doors is one of the best ways to protect your property from high energy costs.

Nairn homes come in all shapes and sizes, and the right window choice depends on your property, the room, and how you live in it.
The Advanced Group provides and installs a full selection of windows and doors in both double glazed and triple glazed configurations, including uPVC triple and double and triple glazed casement, sash, tilt and turn, and top hung types.

The most widely fitted window type in the UK. Side-hinged, opening outwards. Practical for ventilation and easy to clean from inside.
Ideal for most property types, from modern homes to traditional villas, casement windows are available in a wide selection of colours and finishes, including woodgrain effects that recreate the appearance of timber without the maintenance or worry of warping.
Want the look of original wooden sash frames? Our sliding sash windows mirror that classic appearance while packing in modern thermal performance and safety.
The proportions, sight lines, and opening mechanism all match the traditional design, which matters if your property is in a conservation area or you simply want to maintain its character.

Tilt inward at the top for secure ventilation. Turn fully inward on a side hinge for easy cleaning.
They’re particularly popular in upper-floor flats, where climbing up a ladder to clean the outside of the glass isn’t realistic.
Airflow without the security worry of a fully open window. That’s what the tilt mode gives, and it’s especially useful for families with young children.

Hinged at the top, opening outward from the bottom. Practical for ventilation and good at keeping rain out.
They are often chosen in bathrooms, kitchens, stairwells, bay window setups, and other spaces where privacy and airflow are equally needed.

French windows are full-length panels that open outward much like French doors.
Pair them up and match them with sidelights, and you can open up a wide opening with glass and natural light. The finish is striking.

The Advanced Group’s speciality is uPVC frame materials, and this decision is backed by solid reasons.
Scotland’s weather won’t go easy on your windows, and uPVC is built to withstand it. It’s hardwearing, resilient to rough, windy, wet conditions, and unlike timber, it won’t warp the same way.
Not only that, but uPVC is low maintenance.
A simple wipe down with soapy water is all it takes to keep your uPVC windows appearing as good as new.
Energy performance is where our uPVC windows truly shine. Multi-chambered uPVC construction, U-values as low as 0.8 W/m2K on some frames, and a proper difference to the energy performance of your house.
And better of all? uPVC double glazing is also the most affordable option.
Higher-specification glazing without breaking the budget? That’s what uPVC makes. We also stock glazed uPVC doors, including uPVC doors, composite doors, and patio doors to go with.
Let’s be real, Scotland is cold, wet, and windy for a fair chunk of the year!
That climate means the energy efficiency of your windows counts. It influences how much you pay on heating and how warm your home feels from one day to the next.
The thermal performance of a window is assessed by its U-value.
A lower number means less heat escaping through the glass and frame. Currently, Scottish building regulations set a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows perform at 1.2 W/m2K. The premium range? As low as 0.8 W/m2K. Twice as good as the regulatory minimum, comfortably.
The difference shows on your energy statements.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings are fantastic at bouncing heat back into the room while still letting lots of light through.
If you’re upgrading from old single-glazed sash windows or early double glazing from the 1990s, you could see a noticeable drop in your heating bills within the first winter.
A lot of double glazing firms in Nairn sell entry-level products, but not many can compete with the calibre of the windows and doors we fit.
Our experienced installers enjoy chatting about triple glazing, and it’s a question that arises regularly!
The additional pane of glass in triple glazing enables it to provide superior insulation and better noise control.
If your property is perched in an exposed spot, up a hill, facing north, or near a busy road or under a flight path, get in touch! The Advanced Group would be more than pleased to walk you through the benefits of triple glazing.
