New Windows Millhill
Quality Energy Efficient Double Glazed Windows & Doors




You’ve spotted the temperature changing in your home. Bills are climbing. Condensation sits on or inside your windows each morning.
Sound familiar? Your windows are sending you a message.
Old windows drop their seal as the years pass.
The gas between the panes escapes out, the rubber gaskets go hard and pull back, and what once kept the cold now hardly slows it down.
In a city like Millhill, where rain and wind can frequently feel more common than the sun, tired windows make a real difference to how warm and pleasant your home feels.
But don’t worry, The Advanced Group is here to support you with more than 38 years of trusted experience. Whether it’s new windows for one room or a complete house of replacement windows and doors, we’ll help you find the right solution and get everything installed correctly.

Some problems are obvious. Cracked glass, rotten timber frames, handles that don’t close properly.
But other signs are harder to notice, and by the time you catch them, they’ve probably already been losing you money for months, perhaps even years.

Can you see moisture or fogging trapped between the two sheets of glass? That tells you the sealed unit has failed.
Once the seal goes, the argon gas that provides insulation escapes, and the window loses a significant chunk of its thermal performance.
Don’t waste money away with rising heating costs and make sure to bring back your home’s thermal performance with properly sealed new windows.

Hold your hand near the window edges on a windy day. Cold air sneaking through? The seals have deteriorated.
Sure, draught proofing strips can help for a while, but they’re honestly a sticking plaster. The fault only deteriorates as the rubber continues to perishing.

A window that jams, won’t lock properly, or refuses to open is not just an irritation. It’s a safety risk and an insulation issue. Warped frames, worn hinges, and failed mechanisms are the window’s way of telling you it’s finished.
Modern windows feature multi-point locking systems that are far more secure than the single-point catches on older windows. Options like toughened glass provide further protection too.
Your windows are where a significant share of your home’s heat gets out. That thin bridge between you and the outside weather counts more than many people think.
Your old double glazing? It’s outdated! The energy ratings are well below what’s available now, even if the original spec was decent back then.
Protect your property from high energy bills with new double glazed windows and doors.

Millhill homes vary across all forms, and the right window choice depends on your house, the room, and how you occupy it.
The Advanced Group delivers a full selection of windows and doors in both double glazed and triple glazed options, including uPVC casement, sash, tilt and turn, and top hung types.

Casement windows are probably the UK’s most popular window style! They’re side-hinged, open outwards, and are perfect for ventilation and easy to clean from inside.
Casement windows match just about every property style, whether it’s a modern house or a traditional house! They are available in a big range of colours and finishes, and the woodgrain effects look just like real timber without the maintenance or warping worries.

Our sliding sash windows replicate original wooden sash frames. Modern thermal efficiency and safety are built in as standard.
The proportions, sight lines, and opening mechanism all match the traditional look, which matters if your property is in a conservation area or you simply want to keep its personality.

These windows provide two modes: tilting inward at the top for safe ventilation, and turning completely inward on a side hinge for easy cleaning.
If you live in an upper-floor flat, these are a brilliant choice because cleaning the outside of the glass from a ladder just isn’t feasible.
The tilt mode provides airflow without the security worries that come with a fully open window, which is especially handy for families with young children.
Top hung windows open outward from the bottom while being hinged at the top, which is brilliant for getting air in without letting rain in.
You’ll spot top hung windows in bathrooms, kitchens, stairwells, and bay window setups, basically anywhere that privacy and airflow are both needed.

French windows function just like French doors but are full-length windows that open outward.
In pairs, they perform brilliant, and you can match them with sidelights to flood a wide opening with glass and lots of natural light.
The Advanced Group focuses in uPVC frame materials for strong reasons.
Scottish weather is tough, and uPVC is designed to be durable and tough to harsh, windy, and wet weather. Unlike timber frames, uPVC won’t have the same warping or rot concerns.
And there’s one more plus: uPVC is really low maintenance!
Wipe it down with soapy water. Job done. Looks good as new.
But more significantly, our uPVC windows are extremely energy performant. Designed with multi-chambered uPVC, some of our frames can reach a U-value as low as 0.8 W/m2K, working to restore energy efficiency to your house.
And you know the best part? uPVC double glazing is also the most budget-friendly option available!
This means you to often select premium-grade glazing without breaking your budget. We also stock glazed uPVC doors, including uPVC doors, composite doors, and patio doors to coordinate.
For a significant part of the year, Scotland’s climate is cold, wet, and windy.
That weather means the energy performance of your windows counts. It affects how much you spend on heating and how cosy your property feels every single day.
Thermal performance is measured by U-value.
A lower U-value translates to less heat getting out through the glass and frame. Scottish building regulations currently stipulate a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows achieve 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!
And where does that difference appear? Right 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.
Switching from old single-glazed sash windows or 1990s double glazing? You’ll likely notice a noticeable drop in heating bills within the first winter.
Many double glazing businesses in Millhill provide standard products, but few can rival the standard of the windows and doors we supply.

Our trusted installers often get asked about our triple glazing range.
An extra pane of glass makes triple glazing apart. It translates to improved insulation and improved noise dampening over standard double glazing.
If your property is perched in an exposed location, up a hill, facing north, or near a busy road or under a flight path, give us a shout! The Advanced Group would be more than happy to guide you through the upsides of triple glazing.

New windows are an big purchase. Paying for the lot at once? Not always possible. We understand that.
So we make available 0% APR and up to 4 years of interest free credit. No fuss.
This allows you get the windows you want by spreading the cost of your new windows and doors in a way that suits with your finances.
