If you’ve noticed a temperature shift in your house, or seen your bills going up, or condensation forming on or inside your windows in the morning, it’s worth paying attention.
If that seems familiar, your windows are telling you a signal.
Old windows lose their seal over time.
The gas between the panes seeps away, the rubber gaskets go rigid and pull away, and what used to block the cold out now barely holds it back.
In a location like Kelvindale, where rain and wind are sometimes more frequent than sunshine, ageing windows have a clear impact on how warm and comfortable your house feels.
Not to worry. The Advanced Group offers over 38 years of trusted experience. Single room or full house, replacement windows or doors, we’ll find the right fit and fit everything right.

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

If you can see moisture or fogging between the two sheets of glass, the sealed unit has given way.
The seal breaks, and with it goes the argon gas that provided the insulation. The window loses a large chunk of its thermal efficiency.
Climbing heating costs don’t have to eat into your wallet. Restore your home’s thermal efficiency with properly sealed new windows.

Try putting your hand near the edges of your window on a windy day. If you notice cold air getting through, the seals have worn away.
Draught proofing strips buy you time, but they’re a sticking plaster at most. The rubber keeps degrading, and the problem only grows.

Got windows that seize, won’t fasten right, or just refuse to cooperate? That’s a security risk and an insulation concern combined. Warped frames, worn hinges, and failed mechanisms all tell you the window has come to the end of its useful life.
Modern windows have multi-point locking systems that are significantly more safe than the single-point catches on older models. Options like toughened glass add further safety too.
Your windows are behind a large proportion of the heat loss in your home. They’re the bridge between you and the elements.
If your double glazing is ageing, the energy ratings will almost always be far below what’s achievable now, even if they were a decent specification when originally installed.
New double glazed windows and doors will shield your home from high energy costs.

Every Kelvindale property has its own personality. The right window type comes down to the property, the room, and how you occupy it.
A full range of windows and doors, double glazed and triple glazed, is on offer from The Advanced Group, including uPVC casement, sash, tilt and turn, and top hung styles, all supplied and fitted by our installers.

The casement window holds 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 fit with most property styles. Modern builds, traditional villas, the lot in between. Available in a wide range of colours and finishes, including woodgrain effects that deliver the look of timber without the maintenance or warping worry.

The classic look of wooden sash frames, recreated in every detail. That’s what our sliding sash windows offer, along with modern thermal efficiency and protection.
The proportions, sight lines, and opening mechanism match the traditional design. That’s key if your property is in a conservation area or you just want to preserve its character.

Tilt inward at the top for protected ventilation. Turn fully inward on a side hinge for quick cleaning.
For residents in upper-floor flats, tilt and turn windows are a wise choice, as cleaning the outside of the glass from a ladder is not feasible.
The tilt feature delivers airflow without security concerns. Especially valuable for families with young children.
Hinged at the top, opening outward from the bottom. Smart for ventilation and effective at keeping rain out.
Bathrooms, kitchens, stairwells, bay window setups, anywhere privacy and airflow both matter. That’s where top hung windows work best.

Think of them as full-length windows that open outward, much like French doors. That’s French windows in a nutshell.
Paired together, they work brilliantly and can be combined with sidelights to open up a wide opening with glass and natural light.
The Advanced Group focuses in uPVC frame materials, and for really good reasons!
Scotland’s weather doesn’t play nice with your windows, and uPVC is built to withstand it. It’s tough, resilient to harsh, windy, wet conditions, and unlike timber, it won’t warp the same way.
Low maintenance is built in as standard with uPVC.
Just a simple wipe with soapy water and it looks brand new!
More significantly though, our uPVC windows are highly energy effective. With multi-chambered uPVC construction, some of our frames can reach a U-value as low as 0.8 W/m2K, helping to improve your home’s energy performance.
And the best bit? uPVC double glazing is the most cost-effective option out there.
Higher-spec glazing without exceeding the budget? That’s what uPVC makes. We also supply glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.
Cold, wet, and windy. That’s Scotland for a large portion of the year.
In that sort of climate, the energy performance of your windows really influences how much you pay 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.
Lower number, less heat lost. Scottish building regulations currently set a maximum of 1.6 W/m2K for replacement windows.
Our standard double glazed windows perform at 1.2 W/m2K, and the premium range can get down to as low as 0.8 W/m2K. That’s double glazing and triple glazing operating at twice the level of the regulatory minimum.
And where does that difference show up? Right on your energy statements!
A-rated energy-efficient windows and doors, equipped with argon gas filled sealed units and low-E glass coatings, perform by pushing heat back into the room while still managing to let light through.
Upgrading from old single-glazed sash windows or 1990s double glazing? You could see a noticeable drop in heating bills within the first winter.
A lot of double glazing companies in Kelvindale supply standard products, but not many can match the standard of the windows and doors we fit.

Our trusted installers often get asked about our triple glazing range.
Triple glazing adds an extra pane of glass, which delivers stronger insulation and significantly better noise dampening.
If your property is in an exposed location, up a hill, facing north, or near a busy road or flight path, The Advanced Group is more than pleased to walk you through the upsides of triple glazing.

New windows are an significant purchase, and we understand that paying for them all at once isn’t always feasible.
That’s why we have 0% APR and up to 4 years of interest free credit, to make the process much less stressful!
The windows you need, with the cost spread in a way that fits for you. That’s what 0% finance opens up.
