Quality Energy Efficient Double Glazed Windows & Doors




Maybe you’ve noticed a change in temperature in your property. Heating bills creeping up. Or condensation appearing on or inside your windows in the morning.
If that seems familiar, your windows are telling you a message.
As windows get older, they start to lose their seal.
That gas between the panes? It seeps away. The rubber gaskets go rigid and pull away. And what used to keep the cold out barely holds up.
In a place like North Middleton, where rain and wind can often feel more frequent than the sun, tired windows make a real difference to how warm and pleasant your house feels.
But not to fret, The Advanced Group is here to lend a hand with more than 38 years of trusted service. Whether it’s new windows for one room or a complete house of replacement windows and doors, we’ll find you the right fit and have everything fitted correctly.

Cracked glass? Rotten timber frames? Handles that don’t lock properly? Some issues are easy to spot.
Other signs are trickier to spot. By the time you see them, they’ve been costing you money for months or years.

Moisture or fogging between the two sheets of glass? The sealed unit has gone.
The seal goes, and with it escapes the argon gas that kept the insulation. The window loses a significant chunk of its thermal efficiency.
Why throw money away on increasing heating prices? Restore your home’s thermal performance with perfectly sealed new windows instead.

On a windy day, hold your hand near the edges of the window. If you can feel cold air flowing through, this suggests the seals have deteriorated.
Sure, draught proofing strips can do something for a short time, but they’re just a sticking plaster. The issue only gets worse as the rubber keeps perishing.

Sticking windows that won’t close correctly aren’t just frustrating, they’re a security risk and an insulation problem too. Warped frames, worn hinges, and failed mechanisms all point to a window that’s come to the end of its useful life.
Multi-point locking systems far exceed the old single-point catches for safety. Toughened glass adds another layer of security.

A large proportion of heat loss in any property happens through the windows. They form the barrier between your living space and the outside elements.
Old double glazing doesn’t keep up. The energy ratings are significantly below what’s on offer now, even if the original spec was solid at the time.
High energy bills don’t have to be the norm. New double glazed windows and doors help shield your property and pull those bills down.

Every North Middleton house is different, and the right window type depends on the building, the room, and how you use it.
The Advanced Group offers a full range of windows and doors in both double glazed and triple glazed specifications, including uPVC casement, sash, tilt and turn, and top hung styles.
The casement window claims the crown of the UK’s most popular type. Side-hinged and opening outwards, they’re ideal for ventilation and a doddle to clean from inside.
Casement windows suit just about any property kind, whether it’s a modern build or a traditional property! They come in a huge range of colours and finishes, and the woodgrain effects look just like real timber without the maintenance or warping worries.

The traditional look of wooden sash frames, mirrored in every detail. That’s what our sliding sash windows deliver, along with modern thermal efficiency and safety.
Every proportion, sight line, and opening mechanism mirrors the traditional look. Whether your property is in a conservation area or you simply want to keep its character, these windows do the job.
These windows give two options: tilting inward at the top for protected ventilation, and turning completely inward on a side hinge for easy cleaning.
If you are in an upper-floor flat, these are a brilliant option because cleaning the outside of the glass from a ladder just isn’t an option.
The tilt feature gives you airflow without the safety worries of a fully open window, which is particularly valuable for families with young children.
Top hung windows are hinged at the top and open outward from the bottom, providing a smart choice for ventilation that also works to keep rain out.
You’ll often see them in bathrooms, kitchens, stairwells, and bay window setups, rooms where both privacy and airflow count.

French windows look just like French doors but are full-length windows that open outward.
Pair them up and combine them with sidelights, and you can fill a wide opening with glass and natural light. The result is stunning.

The Advanced Group concentrates in uPVC frame materials, and for some genuinely good reasons!
Scottish weather is unforgiving. uPVC is made to take it. Durable, resilient to wild, windy, wet conditions. No warping or rot worries like timber.
Not only that, but uPVC is low maintenance.
Just give it a wipe with soapy water and it’ll look good as new.
Energy performance is where our uPVC windows truly stand out. Multi-chambered uPVC construction, U-values as low as 0.8 W/m2K on some frames, and a real improvement to the energy efficiency of your home.
And best of all? uPVC double glazing is also the most budget-friendly option.
Higher-spec glazing without blowing the budget? That’s what uPVC makes. We also supply glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.

Scotland’s weather is cold, wet, and windy for a large chunk of the year.
With that environment, your windows’ energy rating genuinely affects your heating costs and how cosy your house feels day to day.
U-value. That’s the figure that reveals you how thermally efficient a window really is.
A lower figure means less heat getting out through the glass and frame. Currently, Scottish building regulations require a maximum U-value of 1.6 W/m2K for replacement windows.
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.
The difference shows up on your energy bills.
Argon gas filled sealed units and low-E glass coatings perform the real work in A-rated energy-efficient windows and doors. Heat gets pushed back in. Light still gets through.
If you’re switching from old single-glazed sash windows or early double glazing from the 1990s, you could see a real drop in your heating costs within the first winter.
There are lots of double glazing companies in North Middleton offering basic products, but not many can match the standard of what we install.

Our trusted installers often get asked about our triple glazing products.
Triple glazing adds an extra pane of glass, which provides better insulation and clearly better noise dampening.
If your property is in an exposed location, at a raised altitude, facing north, or close to a busy road or flight path, The Advanced Group would be more than happy to walk you through the benefits of triple glazing.

We understand that new windows represent a notable spend, and paying for them in full all at once isn’t always possible.
So we make available 0% APR and up to 4 years of interest free credit. No fuss.
The windows you deserve, with the cost spread in a way that fits for you. That’s what 0% finance makes.
