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

New Windows Brechin
Quality Energy Efficient Double Glazed Windows & Doors




Maybe you’ve felt a change in temperature inside your house. Energy bills rising. Or condensation building up on or inside your windows every morning.
If that matches your home, your windows are sending you a clear signal.
Over time, older windows begin to lose their seal.
That gas between the panes? It leaks out. The rubber gaskets go rigid and pull away. And what once kept keep the cold out no longer does the job.
Living in Brechin, you know that rain and wind sometimes outweigh the sunny days, and ageing windows make a real difference to how warm and comfortable your home feels.
Over 38 years in the industry, and The Advanced Group is still here, on hand to support you. Whether it’s one room or the full house that needs new windows and doors, we’ll find the right option and get everything installed the right way.

Certain signs are hard to miss. Cracked glass, rotten timber frames, handles that don’t fasten properly.
Other signs are trickier to spot. By the time you do, they’ve been costing you money for months or years.

Moisture or fogging between the two sheets of glass? The sealed unit has broken down.
Once the seal has broken, the argon gas responsible for insulation leaks, and the window loses a substantial chunk of its thermal performance.
Climbing heating prices don’t have to drain your wallet. Restore your home’s thermal performance with properly sealed new windows.

Try putting your hand near the edges of your window on a windy day. If you can feel cold air coming through, the seals have deteriorated.
Draught proofing strips can help for a while, but they’re a sticking plaster on a problem that will only worsen as the rubber keeps on degrade.

A window that jams, won’t fasten right, or refuses to budge is more than an inconvenience. It’s a security risk and an insulation issue. Warped frames, worn hinges, and failed mechanisms are the window’s way of saying it’s done.
Modern windows come with multi-point locking systems that are far more safe than the single-point catches on older models. Options like toughened glass give additional protection too.

Your windows are the cause of a significant proportion of the heat loss in your house. They’re the barrier between you and the outside world.
Double glazing from the past is just that, in the past. The energy ratings fall well below modern options, even if the original spec was reasonable when first installed.
Installing new double glazed windows and doors is one of the most effective ways to shield your house from high energy costs.

Every Brechin house has its own personality. The right window style depends on the house, the room, and how you live in it.
The Advanced Group delivers a full choice of windows and doors in both double glazed and triple glazed options, including uPVC casement, sash, tilt and turn, and top hung styles.

Perhaps the most widely chosen window style in the UK, casement windows are side-hinged and open outwards, which makes them ideal for ventilation and straightforward to clean from inside.
Casement windows fit with most property types. Modern builds, traditional villas, the lot in between. On offer in a wide selection of colours and finishes, including woodgrain effects that replicate the look of 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 deliver, along with modern thermal efficiency and security.
The proportions, sight lines, and opening mechanism all stay true to the traditional style, which is great if your property’s in a conservation area or you just want to hold onto its character.

Tilt and turn windows tilt inward at the top for protected ventilation, and turn fully inward on a side hinge for simple cleaning.
Upper-floor flat? Cleaning outside glass from a ladder isn’t feasible. Tilt and turn windows sort that issue completely.
The tilt mode provides airflow without the security risks that come with a fully open window, which is especially valuable for families with young children.
Top hung windows are hinged at the top and open outward from the bottom, providing a practical choice for ventilation that also works to keep rain out.
They’re often used in bathrooms, kitchens, stairwells, bay window arrangements, and other spaces where privacy and airflow are equally valued.

Full-length windows that open outward like French doors. That’s what French windows are.
In pairs, they work brilliant, and you can match them with sidelights to fill a wide opening with glass and lots of natural light.

We focus in uPVC frame materials. And for solid reason.
Scottish weather throws all sorts at your windows. uPVC is built to handle it, tough, resistant to wild, windy, wet weather, and free from the warping or rot issues that plague timber frames.
And here’s one more plus: uPVC is really low maintenance!
Simply wipe it down with soapy water and it can look fresh.
More to the point though, our uPVC windows are highly energy efficient. With multi-chambered uPVC design, some of our frames can achieve a U-value as low as 0.8 W/m2K, helping to improve your home’s energy performance.
On top of all that, uPVC double glazing is also the most affordable option on the market.
That lets you can often step up to higher-spec glazing without breaking the budget! We also offer glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.
Scotland gives cold, wet, and windy weather for a good portion of the year.
That climate means the energy rating of your windows matters. It influences how much you spend on heating and how comfortable your house feels from one day to the next.
Ever heard of U-values? That’s how the thermal performance of any window is measured.
A lower U-value translates to less heat getting out through the glass and frame. Scottish building regulations currently 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 proof? It shows up on your energy costs.
A-rated energy-efficient windows and doors, equipped with argon gas filled sealed units and low-E glass coatings, function by pushing heat back into the room while still allowing to let light through.
If you’re upgrading from old single-glazed sash windows or early double glazing from the 1990s, you could see a significant drop in your heating costs within the first winter.
Many double glazing companies in Brechin sell basic products, but few can rival the standard of the windows and doors we provide.

We get asked about triple glazing a lot.
With an extra pane of glass, triple glazing provides better insulation and better noise reduction.
If your property is situated in an exposed spot, up a hill or high above sea level, facing north, or near a busy road or under a flight path, The Advanced Group would be more than glad to guide you through the advantages of triple glazing.

We fully get that new windows are an big purchase, and paying for everything at once isn’t always realistic.
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 by helping you spread the cost of your new windows and doors in a way that suits for you.
