Quality Energy Efficient Double Glazed Windows & Doors




Perhaps you’ve spotted a change in temperature in your property. Heating bills rising. Or condensation appearing on or inside your windows in the morning.
Sound familiar? Your windows are telling you a signal.
Over time, older windows gradually lose their seal.
That gas between the panes? It leaks out. The rubber gaskets stiffen and shrink. And what once kept keep the cold out barely holds up.
In a place like Perth, where rain and wind can often feel more frequent than the sun, tired windows make a real difference to how warm and pleasant your home feels.
The Advanced Group is here to help, with over 38 years of trusted experience. Whether you want new windows for a single room or a full house of replacement windows and doors, we’ll guide you to the right fit and make sure everything is fitted correctly.

The easy ones jump out. Cracked glass, rotten timber frames, handles that won’t close properly.
Other signs, however, are easier to miss, and by the time you notice, they might have been costing you money for months or even years.

If you can see moisture or fogging between the two sheets of glass, the sealed unit has failed.
Once the seal has broken, the argon gas responsible for insulation escapes, and the window loses a significant amount of its thermal performance.
Rising heating prices don’t have to keep climbing. Properly sealed new windows will restore your home’s thermal efficiency and help push those costs back down.

Put your hand near the window edges on a windy day. Cold air getting through? The seals have deteriorated.
Draught proofing strips give a temporary fix, but they’re essentially a sticking plaster on a fault that will only deteriorate as the rubber continues to degrade.

Got windows that jam, won’t lock right, or just refuse to play along? That’s a security risk and an insulation issue combined. Warped frames, worn hinges, and failed mechanisms all tell you the window has hit the end of its useful life.
Multi-point locking systems beat the old single-point catches for protection. Toughened glass provides extra security.

Windows let out a large proportion of your home’s heat. They’re the barrier between you and the outside world.
Old double glazing can’t compare. The energy ratings are significantly below what’s on offer today, even if the original spec was solid at the time.
New double glazed windows and doors will shield your home from high energy costs.

No two Perth homes are the same, and the ideal window style comes down to on the house, the room, and how you use it.
We stock and fit a full range of double glazed and triple glazed windows and doors, including uPVC casement, sash, tilt and turn, and top hung styles.

Perhaps the most common window style in the UK, casement windows are side-hinged and open outwards, which makes them ideal for ventilation and straightforward to clean from inside.
Casement windows work with most property types. Modern homes, traditional houses, everything in between. Available in a wide selection of colours and finishes, including woodgrain effects that replicate the look of timber without the maintenance or warping worry.

Our sliding sash windows replicate the look of original wooden sash frames while providing modern thermal performance and protection.
The proportions, sight lines, and opening mechanism are all designed to follow the traditional design, which is particularly relevant if your property is in a conservation area or you wish to maintain its personality.

Tilt them inward at the top for safe ventilation. Turn them fully inward on a side hinge for quick cleaning. Two functions, one window.
Upper-floor flat? Cleaning outside glass from a ladder isn’t an option. Tilt and turn windows solve that issue completely.
The tilt mode allows air in without the security worries of having the window fully open, which is especially valuable if you’ve got young children.
Hinged at the top, opening outward from the bottom. Smart for ventilation and great at keeping rain out.
They’re often fitted in bathrooms, kitchens, stairwells, bay window configurations, and other spaces where privacy and airflow are equally important.

Think of them as full-length windows that open outward, exactly like French doors. That’s French windows for you.
Pair them up and match them with sidelights, and you can fill a wide opening with glass and natural light. The result is striking.

uPVC frame materials. That’s what The Advanced Group focuses in, and the reasons are solid.
Scottish weather is unforgiving. uPVC is made to take it. Durable, resistant to wild, windy, wet weather. No warping or rot worries like timber.
Beyond that, uPVC delivers the advantage of being low maintenance.
Simply wipe it down with soapy water and it can look brand new.
The main selling point? Energy efficiency. Our uPVC windows feature multi-chambered uPVC, and some frames achieve a U-value as low as 0.8 W/m2K. That recovers proper energy efficiency to your property.
And the better bit? uPVC double glazing is the most cost-effective option on the market.
This means you to often choose premium-grade glazing without blowing your budget. We also offer glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.
Cold, wet, and windy. That’s Scotland for a large part of the year.
With that climate, your windows’ energy rating really affects your heating costs and how comfortable your house feels every day.
Thermal efficiency is measured by U-value.
The lower that figure goes, the less heat gets through. Scottish building regulations cap the maximum at 1.6 W/m2K for replacement windows right now.
Our standard double glazed windows perform at 1.2 W/m2K, and the premium models can achieve as low as 0.8 W/m2K. That’s double glazing and triple glazing performing at twice the level of the regulatory minimum.
That improvement is clearly shown on your energy statements.
A-rated energy-efficient windows and doors use argon gas filled sealed units and low-E glass coatings to reflect heat back into the room, all while allowing natural light through.
Old single-glazed sash windows or 1990s double glazing? Upgrade them, and you could see a clear drop in heating spend before the first winter is done.
Many double glazing businesses in Perth sell standard products, but few can match the calibre of the windows and doors we provide.

Our experienced installers love chatting about triple glazing, and it’s a question that pops up frequently!
With an extra pane of glass, triple glazing provides stronger insulation and greater noise control.
If your property is located in an exposed location, 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 willing to guide you through the benefits of triple glazing.

We appreciate that new windows are an investment, and paying for them all at once isn’t always possible.
To assist with this, we provide 0% APR and up to 4 years of interest free credit.
This helps you get the windows you need by spreading the cost of your new windows and doors in a way that works for you.
