We’ve installed thousands of windows over the last 34 years, take a look at what we have installed more recently.

Quality Energy Efficient Double Glazed Windows & Doors




A shift in temperature inside the home. Climbing bills. Condensation sitting on or inside the windows come morning. Ring any bells?
If that sounds familiar, your windows are telling you something.
Old windows lose their seal with age.
That gas between the panes? It escapes. The rubber gaskets stiffen and contract. And what previously did keep the cold out no longer does the job.
Tranent sees its fair share of rain and wind, sometimes more than sunshine. When your windows are worn, you feel the difference in how warm and comfortable your home remains.
But don’t worry, The Advanced Group is here to lend a hand with more than 38 years of trusted know-how. Whether it’s new windows for a single room or a full house of replacement windows and doors, we’ll find you the right solution and get everything installed properly.

Some faults are obvious. Cracked glass. Rotten timber frames. Handles that don’t lock correctly.
Other symptoms, however, are harder to spot, and by the time you notice, they may have been costing you money for months or even years.

Moisture or fogging between the two sheets of glass? The sealed unit has failed.
The seal breaks, and with it leaks the argon gas that kept the insulation. The window loses a major portion of its thermal efficiency.
Quit pouring money away on increasing heating costs. Bring back your home’s thermal efficiency with well sealed new windows.

Try placing your hand near the edges of your window on a windy day. If you notice cold air getting through, the seals have broken down.
Draught proofing strips? They’re a short-term fix. The fault only worsens as the rubber continues to perish.

Windows that stick, won’t lock properly, or refuse to open are both a safety risk and an insulation issue. Warped frames, worn hinges, failed mechanisms. The window has come to the end of its functional life.
Multi-point locking systems on newer windows offer significantly stronger security than the single-point catches used in older windows, and toughened glass choices give an extra layer of security.

Your windows are where a considerable share of your home’s heat is lost. That thin barrier between you and the outside elements counts more than most people realise.
Double glazing from years ago is outdated, and the energy ratings will be far below what’s on offer now, even if the specification was good at the time.
Guard your house from expensive energy bills. New double glazed windows and doors make the difference.

Tranent houses come in all shapes and sizes, and the right window choice depends on your building, the room, and how you occupy it.
A full lineup of windows and doors, double glazed and triple glazed, is available from The Advanced Group, including uPVC casement, sash, tilt and turn, and top hung designs, all supplied and fitted by our installers.
The casement window claims the title of the UK’s most common type. Side-hinged and opening outwards, they’re practical for ventilation and a breeze to clean from inside.
Casement windows complement most property styles, from modern houses to traditional properties, and are available in a wide selection of colours and finishes, including woodgrain effects that replicate the look of timber without the maintenance and risk of warping.

Our sliding sash windows recreate the look of original wooden sash frames while providing modern thermal performance and safety.
The proportions, sight lines, and opening mechanism all match the traditional look, which is perfect if your property’s in a conservation area or you just want to maintain its personality.
These windows give two functions: tilting inward at the top for secure ventilation, and turning fully inward on a side hinge for easy cleaning.
For residents in upper-floor flats, tilt and turn windows are a popular choice, as cleaning the outside of the glass from a ladder is not realistic.
Airflow without the security risk of a fully open window. That’s what the tilt function provides, and it’s particularly useful for families with young children.
Top hung windows open outward from the bottom while being hinged at the top, which is brilliant for letting air in without allowing rain in.
They are commonly fitted in bathrooms, kitchens, stairwells, bay window arrangements, and other spaces where privacy and airflow are equally valued.

French windows are full-length panels that open outward just like French doors.
They’re ideal in pairs and can be combined with sidelights to flood a wide opening with glass and natural light.

There are solid reasons why The Advanced Group focuses in uPVC frame materials.
Scottish weather is tough. uPVC is made to withstand it. Hardwearing, resilient to rough, windy, wet conditions. No warping or rot issues like timber.
In addition, uPVC provides the benefit of being low maintenance.
A quick wipe down with soapy water is all it needs to have your uPVC windows appearing fresh.
The main benefit? Energy performance. Our uPVC windows use multi-chambered uPVC, and some frames achieve a U-value as low as 0.8 W/m2K. That restores genuine energy efficiency to your home.
And best of all? uPVC double glazing is also the most affordable option.
So you can often install premium-grade glazing and still stay within budget. We provide glazed uPVC doors too, including uPVC doors, composite doors, and patio doors to complement.

Scotland delivers cold, wet, and windy weather for a large chunk of the year.
In that climate, the energy rating of your windows makes a measurable difference to how much you spend on heating and how cosy your home feels every day.
A window’s thermal performance is measured by something called its U-value.
A lower value means less heat getting out through the glass and frame. At present, Scottish building regulations set a maximum U-value of 1.6 W/m2K for replacement windows.
Standard double glazed windows: 1.2 W/m2K. Premium options: as low as 0.8 W/m2K. That’s twice as efficient as the regulatory minimum.
The evidence? It lands on your energy statements.
A-rated windows and doors. Argon gas filled sealed units. Low-E glass coatings. Heat bounced back in, light still coming through.
Switching from old single-glazed sash windows or 1990s double glazing? Expect a real drop in heating costs within the first winter.
There are plenty of double glazing companies in Tranent supplying basic products, but not many can come close to the calibre of what we provide.

Triple glazing is one of the most regular topics our trusted installers hear.
An extra pane of glass sets triple glazing apart. It means enhanced insulation and improved noise reduction over standard double glazing.
Exposed spot? Up a hill? Facing north? Near a busy road or flight path? The Advanced Group will talk you through the advantages of triple glazing.

We appreciate that new windows represent a notable spend, and paying for them in full all at once isn’t always feasible.
That’s why we have 0% APR and up to 4 years of interest free credit.
This allows you to get the windows you need while spreading the cost of your new windows and doors in a way that fits your budget.
