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

Quality Energy Efficient Double Glazed Windows & Doors




You’ve spotted the temperature dropping in your home. Heating costs are up. Condensation gathers on or inside your windows each morning.
If that sounds familiar, your windows are telling you a signal.
Over time, older windows begin to lose their seal.
The gas between the panes leaks out, the rubber gaskets harden and shrink, and what used to block the cold out now barely slows it down.
In Kilsyth, where the rain and wind can seem more regular than sunshine, worn-out windows definitely impact how warm and cosy your home feels.
No need to panic about it! The Advanced Group has been in the business for over 38 years. Whether you need new windows for just one room or the whole house of replacement windows and doors, we’ll match you with the right choice and get it all fitted properly.

Some problems are easy to spot. Cracked glass, rotten timber frames, handles that don’t fasten properly.
But then there are the subtle signs. The ones you miss until they’ve already been costing you money for months, maybe years.

Spotting moisture or fogging between your two panes of glass indicates the sealed unit has broken down.
Once the seal breaks, the argon gas that provides insulation escapes, and the window loses a large portion of its thermal performance.
Don’t throw money away with increasing heating costs and make sure to recover your home’s thermal performance with perfectly sealed new windows.

A windy day shows you a lot. Hold your hand near the edges of the window. Cold air coming through tells you the seals have gone.
Draught proofing strips offer you time, but they’re a sticking plaster at best. The rubber continues to breaking down, and the issue only grows.

If your windows jam, won’t close correctly, or are difficult to operate, this presents both a security risk and an insulation concern. Warped frames, worn hinges, and failed mechanisms are all signs that the window has reached the end of its useful life.
Modern windows use multi-point locking systems that are miles ahead of the single-point catches on older frames. Throw in toughened glass, and you’ve got significantly better safety.
Your windows are where a considerable share of your home’s heat is lost. That thin boundary between you and the outside elements counts more than many people realise.
Double glazing from years ago is a thing of the past, and the energy ratings will be far below what’s on offer today, even if the spec was decent at the time.
Shield your house from high energy bills. New double glazed windows and doors deliver the difference.

Every Kilsyth house is different, and the right window type depends on the property, the room, and how you live in it.
The Advanced Group supplies and fits 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 types.

The most common window style in the UK. Side-hinged, opening outwards. Great for ventilation and easy to clean from inside.
Modern build or traditional villa, casement windows complement the lot. A wide choice of colours and finishes is provided, and the woodgrain effects mimic the look of timber without any of the maintenance or warping risk.

Our sliding sash windows replicate original wooden sash frames. Modern thermal performance and safety are built in as standard.
Every proportion, sight line, and opening mechanism mirrors the traditional style. Whether your property sits in a conservation area or you simply want to hold onto its charm, these windows deliver.

Tilt them inward at the top for protected ventilation. Turn them fully inward on a side hinge for easy cleaning. Two options, one window.
For residents in upper-floor flats, tilt and turn windows are a wise choice, as cleaning the outside of the glass from a ladder isn’t an option.
The tilt feature enables airflow without the security risks that come with a fully open window, which is especially valuable for families with young children.
Hinged at the top, opening outward from the bottom. Practical for ventilation and great at keeping rain out.
They are commonly fitted in bathrooms, kitchens, stairwells, bay window configurations, and other spaces where privacy and airflow are equally needed.

Full-length windows that open outward like French doors. That’s exactly what French windows offer.
Pair them up and combine them with sidelights, and you can open up a wide opening with glass and natural light. The result is striking.
The Advanced Group concentrates in uPVC frame materials, and for very good reasons!
Scottish weather is unforgiving, and uPVC is designed to be durable and resilient to wild, windy, and wet weather. Unlike timber frames, uPVC won’t have the same warping or rot issues.
Better still, uPVC is really low maintenance.
Just grab it a wipe with soapy water and it’ll look brand new.
And here’s the really important part: our uPVC windows are seriously energy effective! Designed with multi-chambered uPVC, some of our frames reach a U-value as low as 0.8 W/m2K, which seriously works to boost your home’s energy efficiency.
And you know the best bit? uPVC double glazing is also the most budget-friendly option available!
This means you can often fit higher-specification glazing without blowing the budget. We also supply glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.
Let’s be real, Scotland is cold, wet, and windy for a large chunk of the year!
That weather means the energy performance of your windows counts. It influences how much you spend on heating and how cosy your property feels from one day to the next.
The thermal efficiency of a window is determined by its U-value.
Lower value, less heat escaping. Scottish building regulations currently set a maximum of 1.6 W/m2K for replacement windows.
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 top-performing double glazing and triple glazing that works twice as well as the regulatory minimum.
The difference appears on your energy costs.
A-rated energy-efficient windows and doors feature argon gas filled sealed units and low-E glass coatings to bounce heat back into the room, all while letting natural light through.
If you’re upgrading from old single-glazed sash windows or 1990s double glazing, you could see a significant drop in your heating costs within the first winter.
Kilsyth has no shortage of double glazing companies. Few match the standard of our windows and doors.

Our trusted installers are frequently asked about the triple glazing options we offer.
Triple glazing has an extra pane of glass, allowing it to deliver improved insulation and better noise control.
If your property is positioned 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.

New windows are an significant spend. Paying all at once isn’t always possible. We understand that.
That’s why we provide 0% APR and up to 4 years of interest free credit.
The windows you deserve, with the cost spread in a way that works for you. That’s what 0% finance makes.
