New Windows Bothwell
Quality Energy Efficient Double Glazed Windows & Doors




Maybe you’ve felt a change in temperature inside your house. Heating costs going up. Or condensation collecting on or inside your windows every morning.
Does that hit home? Your windows are letting you know something’s.
Over time, older windows start to lose their seal.
The gas between the panes seeps out, the rubber gaskets harden and contract, and what once kept the cold now hardly does anything.
In Bothwell, where the rain and wind can appear more frequent than sunshine, ageing windows truly impact how warm and cosy your house feels.
Not to worry. The Advanced Group has over 38 years of trusted expertise. Single room or full house, replacement windows or doors, we’ll find the right solution and install everything correctly.

Certain signs are obvious. Cracked glass, rotten timber frames, handles that won’t lock correctly.
But other symptoms are easier to miss, and by the time you spot them, they’ve probably already been costing you money for months, maybe even years.

Can you spot moisture or fogging sitting between the two sheets of glass? That means the sealed unit has given way.
The seal goes, and with it leaks the argon gas that provided the insulation. The window loses a major portion of its thermal performance.
Climbing heating prices don’t have to keep eating into your pocket. Properly sealed new windows will bring back your home’s thermal efficiency and help pull those costs back down.

A windy day shows you everything. Hold your hand near the edges of the window. Cold air getting through means the seals have deteriorated.
Draught proofing strips? They’re a quick fix. The fault only worsens as the rubber keeps perish.

Got windows that seize, won’t lock right, or just refuse to cooperate? That’s a safety risk and an insulation issue rolled into one. Warped frames, worn hinges, and failed mechanisms all tell you the window has come to the end of its useful life.
Multi-point locking systems on modern windows are much more safe than the single-point catches on older windows, and options like toughened glass add further security.
Windows leak a considerable proportion of your home’s heat. They’re the barrier between you and the outside world.
Double glazing from the past is exactly that, in the past. The energy ratings fall well below current options, even if the original specification was reasonable at the time.
High energy bills don’t have to be the norm. New double glazed windows and doors work to protect your home and pull those bills down.

Every Bothwell property is different, and the right window type depends on the house, the room, and how you live in it.
The Advanced Group supplies and fits a wide range of windows and doors in double glazed and triple glazed options, including uPVC casement, sash, tilt and turn, and top hung designs.

The most widely fitted window type in the UK. Side-hinged, opening outwards. Ideal for ventilation and simple to clean from inside.
Casement windows match just about every property style, whether it’s a modern house or a traditional villa! They are available in a wide range of colours and finishes, and the woodgrain effects look just like real timber without the maintenance or warping risk.

The classic look of wooden sash frames, recreated in every detail. That’s what our sliding sash windows offer, along with modern thermal performance and safety.
The proportions, sight lines, and opening mechanism all mirror the traditional look, which matters if your property is in a conservation area or you simply want to preserve its charm.

Tilt and turn windows tilt inward at the top for secure ventilation, and turn fully inward on a side hinge for easy cleaning.
If you are in an upper-floor flat, these are a great option because cleaning the outside of the glass from a ladder just isn’t realistic.
The tilt feature delivers airflow without safety concerns. Especially helpful for families with young children.
Top hung windows are hinged at the top and open outward from the bottom, making them a smart choice for ventilation while working to keep rain out.
Bathrooms, kitchens, stairwells, bay window arrangements, anywhere privacy and airflow both matter. That’s where top hung windows really shine.

French windows are full-length panels that open outward just like French doors.
In pairs, they look brilliant, and you can pair them with sidelights to flood a wide opening with glass and plenty of natural light.
uPVC frame materials. That’s what The Advanced Group specialises in, and the reasons are solid.
Scottish weather is tough, and uPVC is designed to be hardwearing and resistant to wild, windy, and wet weather. Unlike timber frames, uPVC won’t have the same warping or rot concerns.
Low maintenance is baked in as standard with uPVC.
Just a simple wipe with soapy water and it can look fresh!
Perhaps most importantly, our uPVC windows deliver high levels of energy performance. Built with multi-chambered uPVC, some of our frames reach a U-value as low as 0.8 W/m2K, helping to restore energy efficiency in your property.
Better of all? uPVC double glazing is the most affordable option.
This means you can often install higher-specification glazing without breaking the budget. We also offer glazed uPVC doors, including uPVC doors, composite doors, and patio doors to coordinate.
For a significant chunk of the year, Scotland’s climate is cold, wet, and windy.
With that environment, your windows’ energy rating directly impacts your heating spend and how cosy your home feels every day.
Know about U-values? That’s how the thermal efficiency of any window is measured.
The lower the value, the less heat gets out through the glass and frame. Scottish building regulations currently set a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows come in at 1.2 W/m2K. The premium range? As low as 0.8 W/m2K. Twice as efficient as the regulatory minimum, easily.
The difference is reflected on your energy bills.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings are brilliant at bouncing heat back into the room while still allowing plenty of light through.
Moving from old single-glazed sash windows or 1990s double glazing? Expect a noticeable drop in heating spend within the first winter.
A number of double glazing companies in Bothwell supply basic products, but not many can rival the standard of the windows and doors we provide.

Our trusted installers are often asked about our triple glazing options.
Triple glazing packs in an extra pane of glass, which delivers enhanced insulation and significantly better noise control.
Exposed location. Up a hill. Facing north. Near a busy road or under a flight path. If any of those fits like your property, The Advanced Group is on hand to walk you through the benefits of triple glazing.

New windows are an investment. Paying for everything at once? Not always possible. We understand that.
That’s exactly why we have available 0% APR and up to 4 years of interest free credit.
It means you can get the windows you deserve by helping you spread the cost of your new windows and doors in a way that fits for you.
