We’ve installed thousands of windows over the last 34 years, take a look at what we have installed more recently.
Fitting Scotland Perfectly
New Windows Lochwinnoch
Quality Energy Efficient Double Glazed Windows & Doors




A change in temperature throughout the house. Increasing energy bills. Condensation sitting on or inside the windows come morning. Ring any bells?
Does that ring true? Your windows are telling you something’s.
The seal on older windows breaks down over time.
The gas between the panes slowly seeps out, the rubber gaskets stiffen and shrink, and what once blocked the cold out now barely makes any difference.
Lochwinnoch gets its fair share of rain and wind, sometimes more than sunshine. When your windows are past their best, you feel the difference in how warm and cosy your house remains.
Not to worry. The Advanced Group has over 38 years of trusted service. Single room or full house, replacement windows or doors, we’ll find the right option and fit everything correctly.

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

Spotting moisture or fogging between your two panes of glass tells you the sealed unit has broken down.
The seal breaks. The argon gas seeps out. The window loses a major chunk of its thermal efficiency.
Climbing heating costs don’t have to eat into your wallet. Recover your home’s thermal efficiency with perfectly sealed new windows.

Try placing your hand near the edges of your window on a windy day. If you can feel cold air coming through, the seals have broken down.
Draught proofing strips might help in the short term, but they’re only a sticking plaster on a fault that’ll only get worse as the rubber continues to degrading.

Sticking windows that won’t fasten right aren’t just inconvenient, they’re a security risk and an insulation problem too. Warped frames, worn hinges, and failed mechanisms all signal a window that’s hit the end of its working life.
Multi-point locking systems beat the old single-point catches for security. Toughened glass gives another layer of safety.
Your windows are the cause of a significant proportion of the heat loss in your property. They’re the bridge between you and the elements.
If your double glazing is old, the energy ratings will most probably be significantly below what’s available today, even if they were a reasonable specification when first fitted.
Want to shield your property from those high energy costs? New double glazed windows and doors are the answer.

No two Lochwinnoch homes are the same, and the right window type comes down to on the house, the room, and how you live in it.
The Advanced Group provides a full choice of windows and doors in both double glazed and triple glazed options, including uPVC casement, sash, tilt and turn, and top hung types.

The casement window holds the crown of the UK’s most widely chosen type. Side-hinged and opening outwards, they’re ideal for ventilation and a doddle to clean from inside.
Casement windows go with most property styles. Modern homes, traditional properties, the lot in between. Provided in a wide range of colours and finishes, including woodgrain effects that deliver the look of timber without the maintenance or warping worry.

Like the look of original wooden sash frames? Our sliding sash windows recreate that original appearance while delivering modern thermal performance and security.
The proportions, sight lines, and opening mechanism are all designed to mirror the traditional style, which is particularly relevant if your property is in a conservation area or you wish to keep its personality.

These windows provide two options: tilting inward at the top for secure ventilation, and turning completely inward on a side hinge for easy cleaning.
They’re especially popular in upper-floor flats, where climbing up a ladder to clean the outside of the glass is not feasible.
The tilt mode provides you airflow without the safety risks of a fully open window, which is especially useful for families with young children.
Hinged at the top, swinging outward from the bottom. Top hung windows offer you ventilation and work to keep the rain out at the same time.
You’ll find top hung windows in bathrooms, kitchens, stairwells, and bay window setups, essentially anywhere that privacy and airflow are both important.

Full-length windows that open outward like French doors. That’s what French windows deliver.
Pair them up and combine them with sidelights, and you can fill a wide opening with glass and natural light. The finish is stunning.
uPVC frame materials. That’s what The Advanced Group focuses in, and the reasons are sound.
Scottish weather is demanding, and uPVC is made to be hardwearing and resilient to wild, windy, and wet weather. Unlike timber frames, uPVC won’t have the same warping or rot worries.
Not only that, but uPVC is low maintenance.
Soapy water and a wipe. That’s all it takes to get uPVC looking good as new.
The real advantage? Energy efficiency. Our uPVC windows use multi-chambered uPVC, and some frames achieve a U-value as low as 0.8 W/m2K. That recovers proper energy performance to your home.
Best of all? uPVC double glazing is the most budget-friendly option.
Premium-grade glazing without exceeding the budget? That’s what uPVC offers. We also supply glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.
Scotland is cold, wet, and windy for a good chunk of the year.
With a climate like that, the energy rating of your windows makes a real difference to what you shell out on heating and how pleasant your home feels every day!
The thermal performance of any window is measured by its U-value.
Lower value, less heat lost. Scottish building regulations currently require a maximum of 1.6 W/m2K for replacement windows.
Our standard double glazed windows come in at 1.2 W/m2K, and the premium range can achieve as low as 0.8 W/m2K. That’s double glazing and triple glazing operating at twice the level of the regulatory minimum.
The result? It appears on your energy costs.
Argon gas filled sealed units and low-E glass coatings do the hard work in A-rated energy-efficient windows and doors. Heat gets reflected back in. Light still comes through.
If you’re coming from old single-glazed sash windows or early double glazing from the 1990s, you could see a genuinely clear drop in your heating bills within even the first winter!
Plenty of double glazing companies in Lochwinnoch offer standard products, but not many can rival the standard of the windows and doors we fit.

We get asked about triple glazing regularly.
The additional pane of glass in triple glazing enables it to offer enhanced insulation and better noise dampening.
If your property is positioned 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 pleased to guide you through the advantages of triple glazing.

New windows are an big purchase. Paying for the lot at once? Not always possible. We understand that.
0% APR. Up to 4 years interest free credit. That’s what we offer.
It lets you get the windows you deserve and spread the cost of your new windows and doors in a way that suits comfortably for you!
