Quality Energy Efficient Double Glazed Windows & Doors




If you’ve noticed a temperature change in your house, or spotted your bills going up, or condensation appearing on or inside your windows in the morning, it’s worth paying attention.
Sound familiar? Your windows are sending you a message.
The seal on older windows breaks down over time.
The gas between the panes leaks out, the rubber gaskets harden and shrink, and what once kept the cold now hardly slows it down.
In a part of the country like Mossend, where rain and wind can often feel more common than the sun, worn windows make a big difference to how warm and cosy your home feels.
Over 38 years in the business, and The Advanced Group is still here, ready to help. Whether it’s one room or the whole house that is due new windows and doors, we’ll find the right solution and have everything fitted the right way.

Some issues are easy to spot. Cracked glass, rotten timber frames, handles that don’t lock properly.
Some signs sneak under the radar however, and by the time you pick up on them, they’ve been silently losing you money for months or even years.

Can you see moisture or fogging trapped between the two sheets of glass? That tells you the sealed unit has broken down.
When the seal breaks, the argon gas that provides insulation leaks, and the window loses a big chunk of its thermal performance.
Rising heating prices don’t have to empty your wallet. Bring back your home’s thermal efficiency with properly sealed new windows.

A windy day reveals you everything. Place your hand near the edges of the window. Cold air sneaking through tells you the seals have deteriorated.
Draught proofing strips provide a temporary measure, but they’re essentially a sticking plaster on a fault that will only get worse as the rubber keeps break down.

If your windows jam, won’t fasten properly, or are difficult to open, this presents both a safety risk and an insulation issue. Warped frames, worn hinges, and failed mechanisms are all indicators that the window has come to the end of its useful life.
Modern windows come with multi-point locking systems that are far more safe than the single-point catches on older models. Options like toughened glass provide extra security too.

Did you know that windows are behind a significant proportion of heat loss in any property? They’re the bridge between your house and the outside elements.
Older double glazing is a thing of the past, and the energy ratings will be far below what’s available now, even if they were a good specification when they were first put in.
Guard your home from high energy bills with new double glazed windows and doors.

Every home in Mossend is different. The right window style depends on the building, the room, and how you occupy it.
The Advanced Group supplies and fits a full range of windows and doors in both double glazed and triple glazed setups, including uPVC triple and double and triple glazed casement, sash, tilt and turn, and top hung types.
Casement windows are likely the most popular window type in the UK. They’re side-hinged and open outwards, making them great for ventilation and easy to clean from inside.
Modern build or traditional house, casement windows complement the lot. A wide selection of colours and finishes is available, and the woodgrain effects capture the look of timber without any of the maintenance or warping worries.

Our sliding sash windows are made to recreate the style of original wooden sash frames, while providing modern standards of thermal performance and safety.
The proportions, sight lines, and opening mechanism all follow the traditional design, which matters if your property is in a conservation area or you simply want to preserve its personality.
Tilt and turn windows tilt inward at the top for secure ventilation, and turn fully inward on a side hinge for easy cleaning.
For those living in upper-floor flats, tilt and turn windows are a practical choice, as cleaning the outside of the glass from a ladder isn’t feasible.
The tilt function is a real plus! You get airflow without the safety worries of a fully open window, which is particularly useful if you’ve got young children at home.
Top hung windows open outward from the bottom while staying hinged at the top, which is brilliant for letting air in without letting rain through.
You’ll often spot them in bathrooms, kitchens, stairwells, and bay window configurations, spaces where both privacy and airflow count.

French windows are full-length units that open outward, working similar to French doors.
Pair them up and match them with sidelights, and you can open up a wide opening with glass and natural light. The result is striking.

We specialise in uPVC frame materials. And for sound reason.
Scottish weather is brutal. uPVC is built to handle it. Durable, resistant to wild, windy, wet weather. No warping or rot worries like timber.
Beyond that, uPVC provides the benefit of being low maintenance.
Wipe it down with soapy water. Done. It looks brand new.
Energy efficiency is where our uPVC windows really deliver. Multi-chambered uPVC engineering, U-values as low as 0.8 W/m2K on some frames, and a proper boost to the energy performance of your home.
The cherry on top? uPVC double glazing is the most affordable option going.
So you can often fit higher-spec glazing and still stay within budget. We provide glazed uPVC doors too, including uPVC doors, composite doors, and patio doors to complement.

Scotland is cold, wet, and windy for a good chunk of the year.
In such a environment, the energy rating of your windows has a genuine effect on your heating spend and the overall comfort of your home day to day.
U-value. That’s the number that reveals you how thermally efficient a window truly is.
The lower that number goes, the less heat gets through. Scottish building regulations cap the maximum at 1.6 W/m2K for replacement windows right now.
Our standard double glazed windows come in at 1.2 W/m2K, and our premium options can reach 0.8 W/m2K! That’s double glazing and triple glazing performing at twice the regulatory minimum!
The difference shows on your energy bills.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings are fantastic at bouncing heat back into the room while still allowing plenty of light through.
If you’re upgrading from old single-glazed sash windows or early double glazing from the 1990s, you could see a genuinely noticeable drop in your heating bills within even the first winter!
There are plenty of double glazing businesses in Mossend selling entry-level products, but not many can match the quality of what we supply.

We get asked about triple glazing regularly.
With an extra pane of glass, triple glazing provides enhanced insulation and better noise reduction.
If your property is situated in an exposed area, 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 happy to guide you through the benefits of triple glazing.

We understand that new windows are an big purchase, and paying for them all at once isn’t always realistic.
0% APR. Up to 4 years interest free credit. That’s what we have available.
This allows you get the windows you deserve by spreading the cost of your new windows and doors in a way that suits around your budget.
