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

New Windows Cardenden
Quality Energy Efficient Double Glazed Windows & Doors




Noticed a temperature change in your house? Energy costs on the rise? Or condensation forming on or inside your windows first thing?
Sound familiar? Your windows are telling you a message.
Older windows drop their seal over time.
Between the panes, the gas seeps away. The rubber gaskets harden and pull away. What used to kept the cold out now hardly does a thing.
In a city like Cardenden, where rain and wind are often more common than sunshine, ageing windows have a noticeable effect on how warm and cosy your house feels.
Over 38 years in the business, and The Advanced Group is still here, available to lend a hand. Whether it’s one room or the entire house that requires new windows and doors, we’ll find the right solution and get everything fitted the right way.

The obvious ones jump out. Cracked glass, rotten timber frames, handles that don’t lock properly.
But other issues are less obvious, and by the time you spot them, they’ve probably already been losing you money for months, maybe even years.

Seeing moisture or fogging between your two sheets of glass indicates the sealed unit has given up.
When the seal goes, the argon gas that delivers insulation leaks, and the window loses a considerable chunk of its thermal ability.
Quit pouring money away on climbing heating bills. Bring back your home’s thermal efficiency with properly sealed new windows.

Here’s a quick test: hold your hand near the edges of the window on a windy day. If cold air is sneaking through, the seals have worn out.
Sure, draught proofing strips can help for a while, but they’re really a sticking plaster. The fault only gets worse as the rubber keeps breaking down.

If your windows stick, won’t lock correctly, or are difficult to operate, this poses both a security risk and an insulation issue. Warped frames, worn hinges, and failed mechanisms are all signals that the window has come to the end of its working life.
Modern windows feature multi-point locking systems that are significantly more secure than the single-point catches on older frames. Options like toughened glass add further security too.

Windows are responsible for a significant proportion of heat loss in any house. It is the boundary between you and the outside world.
Double glazing from the past is exactly that, in the past. The energy ratings land significantly below modern offerings, even if the original specification was solid at the time.
Installing new double glazed windows and doors is one of the most effective ways to guard your house from high energy costs.

Every Cardenden property has its own feel. The right window choice depends on the building, the room, and how you occupy it.
A full selection of windows and doors, double glazed and triple glazed, is ready from The Advanced Group, including uPVC casement, sash, tilt and turn, and top hung designs, all provided and installed by our team.

Casement windows are probably the most common window style in the UK. They’re side-hinged and open outwards, making them practical for ventilation and straightforward to clean from inside.
Modern house or traditional house, casement windows work with the lot. A wide range of colours and finishes is provided, and the woodgrain effects capture the look of timber without any of the maintenance or warping fear.

Our sliding sash windows replicate original wooden sash frames. Modern thermal efficiency and security are built in as standard.
Proportions, sight lines, and opening mechanism all match the traditional look. Great for conservation areas or keeping your property’s character.

Tilt and turn windows tilt inward at the top for secure ventilation, and turn fully inward on a side hinge for easy cleaning.
Common in upper-floor flats. Cleaning the outside from a ladder? Not feasible.
The tilt mode allows air in without the security risks of having the window fully open, which is particularly handy if you’ve got young children.
Hinged at the top, opening outward from the bottom. Smart for ventilation and effective at keeping rain out.
Frequently installed in bathrooms, kitchens, stairwells, and bay window configurations. Every space where privacy and airflow both matter.

Full-length windows that open outward like French doors. That’s exactly what French windows offer.
Paired together, they look wonderfully and can be paired with sidelights to cover a wide opening with glass and natural light.

There are sound reasons why The Advanced Group focuses in uPVC frame materials.
Scottish weather sends the lot at your windows. uPVC is made to handle it, tough, resistant to wild, windy, wet weather, and without the warping or rot concerns that come with timber frames.
uPVC is low maintenance too.
Simply wipe it down with soapy water and it can look as good as new.
The big advantage? 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 performance to your house.
On top of all that, uPVC double glazing is also the most cost-effective option available.
Higher-spec glazing without exceeding the budget? That’s what uPVC allows. We also supply glazed uPVC doors, including uPVC doors, composite doors, and patio doors to go with.
Scotland’s weather is cold, wet, and windy for a fair portion of the year.
In such a environment, the energy efficiency of your windows has a genuine impact on your heating spend and the overall warmth of your home on a daily basis.
U-value. That’s the figure that shows you how effective a window really is.
The lower that number goes, the less heat gets through. Scottish building regulations set the maximum at 1.6 W/m2K for replacement windows currently.
Our standard double glazed windows achieve a U-value of 1.2 W/m2K, while our premium models can achieve values as low as 0.8 W/m2K, working at twice the level of the regulatory minimum.
You’ll see the difference on your energy bills.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings reflect heat back into the room while still allowing light through.
If you’re coming from old single-glazed sash windows or early double glazing from the 1990s, you could see a really noticeable drop in your heating spend within just the first winter!
Cardenden has plenty of double glazing companies. Few rival the calibre of our windows and doors.

Our trusted installers are frequently asked about our triple glazing options.
With an extra pane of glass, triple glazing offers enhanced insulation and improved noise reduction.
If your property is in an exposed position, at a high altitude, facing north, or close to a busy road or flight path, The Advanced Group would be more than pleased to talk you through the advantages of triple glazing.

We totally appreciate that new windows are an investment, and paying for them all at once isn’t always realistic.
That’s why we offer 0% APR and up to 4 years of interest free credit, to make the process much more manageable!
This lets you get the windows you need by spreading the cost of your new windows and doors in a way that suits for you.
