Quality Energy Efficient Double Glazed Windows & Doors




If you’ve noticed a temperature shift in your home, or seen your energy bills climbing, or condensation forming on or inside your windows in the morning, it’s worth paying attention.
If that sounds familiar, your windows are sending you a signal.
The seal on older windows breaks down over time.
The gas between the panes leaks out, the rubber gaskets harden and pull away, and what once did keep the cold out now barely slows it down.
Living in Leith, you know that rain and wind sometimes outweigh the sunny days, and ageing windows make a real difference to how warm and cosy your house feels.
But not to fret, The Advanced Group is here to support you with more than 38 years of trusted experience. Whether it’s new windows for a single room or a complete house of replacement windows and doors, we’ll help you find the right fit and have everything fitted properly.

Certain signs are easy to spot. Cracked glass, rotten timber frames, handles that won’t close the way they should.
Other signs are harder to catch. By the time you do, they’ve been losing you money for months or years.

Can you see moisture or fogging forming between the two sheets of glass? That tells you the sealed unit has broken down.
The seal breaks, and with it goes the argon gas that delivered the insulation. The window loses a large degree of its thermal performance.
Don’t let rising heating bills chip away at your budget. Restore your home’s thermal performance by choosing properly sealed new windows.

A windy day reveals you everything. Place your hand near the edges of the window. Cold air getting through tells you the seals have deteriorated.
Sure, draught proofing strips can help for a bit, but they’re just a sticking plaster. The fault only deteriorates as the rubber continues to breaking down.

Windows that stick, bind, or won’t fasten properly are a safety risk as well as an insulation concern. Warped frames, worn hinges, and failed mechanisms all suggest the window has hit the end of its useful life.
Modern windows come with multi-point locking systems that are far ahead of the single-point catches on older frames. Throw in toughened glass, and you’ve got significantly stronger safety.

A significant amount of heat loss in any property comes from the windows. They act as the boundary between your internal space and the outside weather.
If your double glazing is ageing, the energy ratings will most probably be far below what’s achievable today, even if they were a good specification when first fitted.
Protect your house from expensive energy bills. New double glazed windows and doors make the difference.

Every house in Leith is different. The right window type depends on the house, the room, and how you live in it.
The Advanced Group provides 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 designs.
Casement windows are likely the most common window style in the UK. They’re side-hinged and open outwards, making them ideal for ventilation and simple to clean from inside.
Casement windows work with most property types, from modern builds to traditional houses, and are offered in a wide choice of colours and finishes, including woodgrain effects that recreate the look of timber without the maintenance and fear of warping.

Want the style of original wooden sash frames? Our sliding sash windows mirror that classic style while packing in modern thermal efficiency and protection.
The proportions, sight lines, and opening mechanism all match the traditional style, 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 protected ventilation, and turn completely inward on a side hinge for easy cleaning.
Upper-floor flat? Cleaning outside glass from a ladder isn’t an option. Tilt and turn windows sort that issue completely.
The tilt function provides you airflow without the security concerns of a fully open window, which is especially handy for families with young children.
Top hung windows are hinged at the top and open outward from the bottom, making them a practical choice for ventilation while helping to keep rain out.
Bathrooms, kitchens, stairwells, bay window configurations, anywhere privacy and airflow both matter. That’s where top hung windows work best.

French windows are full-length panels that open outward, working in the same way as French doors.
Pair them up and match them with sidelights, and you can flood a wide opening with glass and natural light. The result is beautiful.

There are good reasons why The Advanced Group focuses in uPVC frame materials.
Scotland’s weather doesn’t go easy on your windows, and uPVC is made to handle it. It’s tough, resistant to harsh, windy, wet weather, and unlike timber, it won’t deteriorate the same way.
Better still, uPVC is incredibly low maintenance.
Soapy water and a wipe. That’s all it takes to keep uPVC looking brand new.
More to the point though, our uPVC windows are seriously energy efficient. With multi-chambered uPVC construction, some of our frames can reach a U-value as low as 0.8 W/m2K, helping to bring back your home’s energy performance.
And better of all? uPVC double glazing is also the most affordable option.
That means you can often upgrade to premium-grade glazing without busting the budget! We also carry glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.

Scotland dishes out cold, wet, and windy weather for a good portion of the year.
With that weather, your windows’ energy rating directly impacts your heating costs and how comfortable your home feels every day.
Know about U-values? That’s how the thermal performance of any window is measured.
A lower U-value means 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 come in at 1.2 W/m2K, and our premium options can hit 0.8 W/m2K! That’s performance at twice the regulatory minimum!
The evidence? It appears on your energy bills.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings send heat back into the room while still letting light through.
If you’re moving from old single-glazed sash windows or early double glazing from the 1990s, you could see a noticeable drop in your heating bills within the first winter.
While many double glazing firms in Leith provide standard products, few can rival the quality of the windows and doors we supply.

Our trusted installers are often asked about the triple glazing options we supply.
With an extra pane of glass, triple glazing offers stronger insulation and better noise reduction.
Exposed location. Up a hill. Facing north. Near a busy road or under a flight path. If any of those sounds like your property, The Advanced Group is ready to walk you through the advantages of triple glazing.

We totally appreciate that new windows are an investment, and paying for everything at once isn’t always practical.
That’s why we provide 0% APR and up to 4 years of interest free credit.
It lets you get the windows you need and spread the cost of your new windows and doors in a way that suits perfectly for you!
