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




Maybe you’ve picked up on a change in temperature throughout your home. Heating costs going up. Or condensation building up on or inside your windows every morning.
Sound familiar? Your windows are sending you a message.
Over time, older windows start to lose their seal.
Between the panes, the gas seeps away. The rubber gaskets harden and pull away. What used to held the cold back now barely does a thing.
In a city like Bathgate, where rain and wind can often feel more regular than the sun, tired windows make a real difference to how warm and cosy your home feels.
No need to worry about it! The Advanced Group has been doing this for over 38 years. Whether you are after new windows for just one room or every room of replacement windows and doors, we’ll match you with the right choice and get it all fitted the right way.

Some faults are plain to see. Cracked glass. Rotten timber frames. Handles that won’t lock properly.
Other signs are harder to spot. By the time you do, they’ve been costing you money for months or years.

Moisture or fogging between the two sheets of glass is a tell-tale sign. The sealed unit has given up.
The seal gives way, and with it goes the argon gas that provided the insulation. The window loses a major chunk of its thermal performance.
Don’t let increasing heating bills drain your budget. Bring back your home’s thermal performance by choosing properly sealed new windows.

Here’s a quick test: place your hand near the edges of the window on a windy day. If cold air is coming through, the seals have worn out.
Draught proofing strips offer you time, but they’re a sticking plaster at most. The rubber keeps degrading, and the problem only grows.

Windows that jam, won’t lock right, or refuse to open are both a safety risk and an insulation concern. Warped frames, worn hinges, failed mechanisms. The window has reached the end of its functional life.
Multi-point locking systems on today’s windows provide much stronger safety than the single-point catches found on older windows, and toughened glass options give an additional layer of protection.

Did you know that windows cause a significant share of heat loss in any property? They’re the bridge between your home and the outside world.
Old double glazing can’t compete. The energy ratings are significantly below what’s available now, even if the original spec was solid when first fitted.
New double glazed windows and doors will guard your home from high energy costs.

Every Bathgate home is different, and the right window style depends on the house, the room, and how you occupy it.
The Advanced Group offers a full choice of windows and doors in both double glazed and triple glazed configurations, including uPVC casement, sash, tilt and turn, and top hung styles.
The casement window holds the spot 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 suit just about every property kind, whether it’s a modern house or a traditional property! They come in a big range of colours and finishes, and the woodgrain effects replicate real timber without the maintenance or warping risk.

Like the look of original wooden sash frames? Our sliding sash windows replicate that classic look while providing modern thermal efficiency and security.
The proportions, sight lines, and opening mechanism all mirror the traditional design, which matters if your property is in a conservation area or you simply want to maintain its character.
These windows offer two functions: tilting inward at the top for secure ventilation, and turning completely inward on a side hinge for simple cleaning.
Popular in upper-floor flats. Cleaning the outside from a ladder? Not feasible.
The tilt mode is a real benefit! You get airflow without the safety worries of a fully open window, which is especially handy if you’ve got young kids at home.
Top hung windows are hinged at the top and open outward from the bottom. This makes them a sensible choice for ventilation while working to keep rain from getting in.
Bathrooms, kitchens, stairwells, bay window arrangements, anywhere privacy and airflow both matter. That’s where top hung windows really shine.

French windows are full-length panels that open outward just like French doors.
They’re ideal in pairs and can be paired with sidelights to fill a wide opening with glass and natural light.

The Advanced Group specialises in uPVC frame materials, and for some genuinely good reasons!
Scottish weather throws everything at your windows. uPVC is made to take it, hardwearing, resilient to harsh, windy, wet conditions, and without the warping or rot concerns that affect timber frames.
In addition, uPVC delivers the benefit of being low maintenance.
Just grab it a wipe with soapy water and it’ll look brand new.
And here’s the genuinely important part: our uPVC windows are properly energy efficient! Made with multi-chambered uPVC, some of our frames reach a U-value as low as 0.8 W/m2K, which really helps restore your home’s energy performance.
And you know the better part? uPVC double glazing is also the most cost-effective option going!
Higher-spec glazing without breaking the budget? That’s what uPVC allows. We also supply glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.

For a good portion of the year, Scotland’s climate is cold, wet, and windy.
In that type of weather, the energy performance of your windows genuinely impacts how much you spend on heating and how comfortable your home feels every day.
A window’s thermal efficiency is measured by something called its U-value.
The lower that number goes, the less heat gets through. Scottish building regulations set the maximum at 1.6 W/m2K for replacement windows right now.
Standard double glazed windows: 1.2 W/m2K. Premium options: as low as 0.8 W/m2K. That’s twice as effective as the regulatory minimum.
You’ll see the difference on your energy bills.
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 allowing to let light through.
If you’re swapping out old single-glazed sash windows or 1990s double glazing, you could spot a noticeable drop in your heating bills within the first winter.
There are lots of double glazing businesses in Bathgate supplying standard products, but not many can match the standard of what we fit.

Our experienced installers enjoy chatting about triple glazing, and it’s a question that comes up regularly!
Triple glazing has an extra pane of glass, enabling it to offer stronger insulation and better noise reduction.
Exposed location? Up a hill? Facing north? Near a busy road or flight path? The Advanced Group will talk you through the benefits of triple glazing.

We understand that new windows are a notable spend, and paying for them in full all at once isn’t always feasible.
That’s why we provide 0% APR and up to 4 years of interest free credit, to make the purchase much easier!
