Quality Energy Efficient Double Glazed Windows & Doors




Noticed a temperature shift in your home? Heating bills on the increase? Or condensation forming on or inside your windows when you wake up?
If that matches your situation, your windows are sending you a sign.
Older windows lose their seal over time.
Gas seeps out from between the panes. The rubber gaskets harden and contract. What once did stop the cold now barely registers.
In a place like Kilmarnock, where rain and wind are often more regular than sunshine, ageing windows have a clear impact on how warm and cosy your home feels.
However not to worry, The Advanced Group is here to help with over 38 years of trusted experience. Whether you require new windows for a single room or a full house of replacement windows and doors, we can point you towards the right solution and get everything installed correctly.

Some faults are obvious. Cracked glass. Rotten timber frames. Handles that won’t fasten right.
But other signs are less obvious, and by the time you spot them, they’ve already been costing you money for months, perhaps even years.

If you can spot moisture or fogging between the two sheets of glass, the sealed unit has broken down.
When the seal breaks, the argon gas that delivers insulation escapes, and the window loses a big chunk of its thermal performance.
Stop wasting money away on increasing heating bills. Restore your home’s thermal efficiency with perfectly sealed new windows.

A windy day tells you all you need to know. Put your hand near the edges of the window. Cold air coming through means the seals have gone.
Draught proofing strips buy you time, but they’re a sticking plaster at best. The rubber keeps breaking down, and the issue only worsens.

A window that jams, won’t fasten right, or struggles 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 saying it’s finished.
Multi-point locking systems on today’s windows deliver far better safety than the single-point catches used in older frames, and toughened glass options give an additional layer of safety.
Windows account for a considerable amount of heat loss in any house. Your window is the bridge between you and the outside elements.
Your old double glazing? It’s a thing of the past! The energy ratings are way below what’s on offer today, even if the original spec was decent when first installed.
Installing new double glazed windows and doors is one of the best ways to guard your home from high energy costs.

Every Kilmarnock house has its own character. The right window choice comes down to the house, the room, and how you use it.
The Advanced Group supplies and installs a complete selection of windows and doors in double glazed and triple glazed options, including uPVC casement, sash, tilt and turn, and top hung designs.

As perhaps the most widely chosen window style in the UK, casement windows are side-hinged and open outwards, offering practical ventilation and simple cleaning from inside.
Casement windows complement just about any property type, whether it’s a modern house or a traditional villa! They are available in a big choice of colours and finishes, and the woodgrain effects replicate real timber without the maintenance or warping fear.

The traditional look of wooden sash frames, replicated 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 match the traditional look. That’s key if your property is in a conservation area or you just want to maintain its charm.

Tilt them inward at the top for protected ventilation. Turn them completely inward on a side hinge for easy cleaning. Two options, one window.
Popular in upper-floor flats. Cleaning the outside from a ladder? Not feasible.
The tilt feature provides you airflow without the safety concerns of a fully open window, which is especially valuable for families with young children.
Hinged at the top, swinging outward from the bottom. Top hung windows offer you ventilation and help keep the rain out at the same time.
They’re often used in bathrooms, kitchens, stairwells, bay window configurations, and other spaces where privacy and airflow are just as needed.

Full-length windows that open outward like French doors. That’s exactly what French windows are.
Pair them up and match them with sidelights, and you can open up a wide opening with glass and natural light. The finish is stunning.
The Advanced Group’s focus is uPVC frame materials, and this decision is supported by good reasons.
uPVC frame materials are especially well suited to the harsh Scottish weather, delivering durability and resistance to rough, windy, and wet weather. Unlike timber frames, uPVC won’t present the same warping or rot issues.
Low maintenance comes in as standard with uPVC.
Just a simple wipe with soapy water and it can look good as new!
Here’s the genuinely exciting part: our uPVC windows are properly energy effective! Built with multi-chambered uPVC, some of our frames achieve a U-value as low as 0.8 W/m2K, which genuinely works to bring back your home’s energy efficiency.
Best of all? uPVC double glazing is the most affordable option.
That allows you can often opt for higher-spec glazing without breaking the budget. We also carry glazed uPVC doors, including uPVC doors, composite doors, and patio doors to go with.
Let’s be real, Scotland is cold, wet, and windy for a good chunk of the year!
With that climate, your windows’ energy rating genuinely impacts your heating bills and how warm your home feels day to day.
A window’s thermal performance is measured by something called its U-value.
The lower that number goes, the less heat gets through. Scottish building regulations require the maximum at 1.6 W/m2K for replacement windows currently.
Our standard double glazed windows achieve 1.2 W/m2K, and our premium options can achieve values as low as 0.8 W/m2K. That’s top-performing double glazing and triple glazing that operates twice as well as the regulatory minimum.
The result? It lands on your energy statements.
A-rated energy-efficient windows and doors feature argon gas filled sealed units and low-E glass coatings to reflect heat back into the room, all while allowing natural light through.
If you’re upgrading from old single-glazed sash windows or early double glazing, you could notice a significant drop in your heating bills within the first winter.
There are plenty of double glazing companies in Kilmarnock selling entry-level products, but not many can come close to the calibre of what we provide.

Our trusted installers are regularly asked about the triple glazing range we supply.
Triple glazing packs in an extra pane of glass, which gives better insulation and noticeably better noise control.
Exposed spot? Up a hill? Facing north? Near a busy road or flight path? The Advanced Group will talk you through the benefits of triple glazing.

New windows are an big purchase. Paying all at once isn’t always realistic. We understand that.
That’s why we have 0% APR and up to 4 years of interest free credit, which makes the process much less stressful!
It means you can get the windows you deserve through helping you spread the cost of your new windows and doors in a way that suits for you.
