New Windows Gullane
Quality Energy Efficient Double Glazed Windows & Doors




Maybe you’ve noticed a change in temperature in your house. Heating bills creeping up. Or condensation appearing on or inside your windows in the morning.
If that describes your home, your windows are sending you a message.
Old windows shed their seal as the years pass.
That gas between the panes? It escapes. The rubber gaskets harden and pull away. And what once kept keep the cold out barely slows it down.
In a place like Gullane, where rain and wind can frequently feel more frequent than the sun, worn windows make a big difference to how warm and cosy your home feels.
But don’t worry, The Advanced Group is here to support you 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 have everything fitted correctly.

Cracked glass? Rotten timber frames? Handles that don’t lock right? Some problems are hard to miss.
But then there are the subtle signs. The ones you overlook until they’ve already been draining you money for months, possibly years.

Moisture or fogging between the two sheets of glass is a tell-tale sign. The sealed unit has failed.
Once the seal has failed, the argon gas responsible for insulation escapes, and the window loses a substantial chunk of its thermal performance.
Rising heating costs don’t have to keep going up. Perfectly sealed new windows will bring back your home’s thermal performance and help bring those costs back down.

On a windy day, place your hand near the edges of the window. If you can feel cold air getting through, this tells you the seals have worn away.
Draught proofing strips offer you time, but they’re a sticking plaster at best. The rubber keeps degrading, and the fault only gets worse.

A window that catches, won’t lock right, or struggles to budge is not just an inconvenience. It’s a security risk and an insulation concern. Warped frames, worn hinges, and failed mechanisms are the window’s way of telling you it’s past its best.
Multi-point locking systems on modern windows are much more secure than the single-point catches on older models, and options like toughened glass provide further protection.

Your windows are the cause of a large proportion of the heat loss in your property. They’re the bridge between you and the weather outside.
Your old double glazing? It’s outdated! The energy ratings are far below what’s on offer now, even if the original spec was decent when first installed.
Guard your home from high energy bills with new double glazed windows and doors.

The right window choice for your Gullane property will depend on the house itself, the room in question, and how you use it.
The Advanced Group provides and installs a full range of windows and doors in both double glazed and triple glazed configurations, including uPVC triple and double and triple glazed casement, sash, tilt and turn, and top hung designs.
As perhaps the most widely chosen window type in the UK, casement windows are side-hinged and open outwards, giving practical ventilation and easy cleaning from inside.
Casement windows complement just about any property style, whether it’s a modern house or a traditional property! They are offered in a wide selection of colours and finishes, and the woodgrain effects mimic real timber without the maintenance or warping worries.

Like the style of original wooden sash frames? Our sliding sash windows replicate that classic style while packing in modern thermal efficiency and security.
The proportions, sight lines, and opening mechanism match the traditional design. That’s essential if your property is in a conservation area or you just want to keep its character.
Tilt inward at the top for protected ventilation. Turn fully inward on a side hinge for simple cleaning.
Upper-floor flat? Cleaning outside glass from a ladder isn’t practical. Tilt and turn windows fix that challenge straight away.
Airflow without the security concern of a fully open window. That’s what the tilt function gives, and it’s particularly handy for families with young children.
Top hung windows are hinged at the top and open outward from the bottom. This makes them a smart choice for ventilation while working to stop rain from getting in.
They are frequently used in bathrooms, kitchens, stairwells, bay window configurations, and other spaces where privacy and airflow are both needed.

French windows are full-length windows that open outward like French doors.
Paired together, they perform beautifully and can be combined with sidelights to open up a wide opening with glass and natural light.

The Advanced Group focuses in uPVC frame materials for strong reasons.
Scottish weather can be brutal, but uPVC takes it all! It’s hardwearing, resists wind, rain, and the harshest of it, and you won’t get the warping or rot issues that timber frames bring.
In addition, uPVC delivers the advantage of being low maintenance.
Just a simple wipe with soapy water and it looks good as new!
More to the point though, our uPVC windows are seriously energy effective. With multi-chambered uPVC design, some of our frames can achieve a U-value as low as 0.8 W/m2K, working to bring back your home’s energy performance.
And the better bit? uPVC double glazing happens to be the most cost-effective option available.
That means you can often step up to premium-grade glazing without blowing the budget! We also stock glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.

Let’s be real, Scotland is cold, wet, and windy for a fair chunk of the year!
In that kind of climate, the energy performance of your windows really impacts how much you spend on heating and how cosy your house feels every day.
A window’s thermal efficiency is measured by what’s known as its U-value.
The lower that number goes, the less heat is lost. Scottish building regulations set the maximum at 1.6 W/m2K for replacement windows at present.
Standard double glazed windows: 1.2 W/m2K. Premium options: as low as 0.8 W/m2K. That’s twice as good as the regulatory minimum.
And where does that difference appear? Right on your energy costs!
A-rated windows and doors. Argon gas filled sealed units. Low-E glass coatings. Heat reflected back in, light still flowing through.
Old single-glazed sash windows or 1990s double glazing? Upgrade them, and you could see a real drop in heating spend before the first winter is over.
Gullane has its share of double glazing businesses, and most sell basic products. Few, however, rival the calibre of the windows and doors provided by The Advanced Group.

Our trusted installers are often asked about our triple glazing options.
The additional pane of glass in triple glazing enables it to deliver enhanced insulation and greater noise control.
If your home is in an exposed location, up a hill, facing north, or near a busy road or flight path, The Advanced Group is more than happy to talk you through the upsides of triple glazing.

We understand that new windows are a significant purchase, and paying for them in full all at once isn’t always feasible.
So we offer 0% APR and up to 4 years of interest free credit. Straightforward.
This enables you to get the windows you deserve while spreading the cost of your new windows and doors in a way that suits your budget.
