Felt a temperature shift in your home? Heating bills on the rise? Or condensation appearing on or inside your windows first thing?

Ring a bell? Your windows are telling you a clear sign.

Old windows shed their seal over time.

That gas between the panes? It leaks out. The rubber gaskets go rigid and contract. And what previously did keep the cold out no longer does the job.

In a part of the country like Drongan, where rain and wind can often feel more frequent than the sun, ageing windows make a big difference to how warm and comfortable your house feels.

No need to panic about it! The Advanced Group has been doing this for over 38 years. Whether you are after new windows for just one room or every room of replacement windows and doors, we’ll guide you to the right solution and get it all fitted the right way.

Double Glazing for New Builds Scotland

When Your Windows Need Replacing

Some issues are plain to see. Cracked glass. Rotten timber frames. Handles that won’t fasten properly.

Other signs are harder to spot. By the time you do, they’ve been losing you money for months or years.

how to stop condensation on windows

Condensation Trapped Between the Panes

Can you spot moisture or fogging trapped between the two sheets of glass? That tells you the sealed unit has failed.

When the seal fails, the argon gas that provides insulation escapes, and the window loses a considerable amount of its thermal ability.

Quit wasting money away on rising heating costs. Restore your home’s thermal performance with perfectly sealed new windows.

draught proofing

Noticing Draughts and Cold Spots

A windy day shows you everything. Place your hand near the edges of the window. Cold air getting through tells you the seals have deteriorated.

Draught proofing strips? They’re a short-term fix. The issue only deteriorates as the rubber continues to degrade.

what are sash windows

Windows That Won’t Budge

If your windows stick, won’t fasten properly, or are tough to open, this creates both a security risk and an insulation issue. Warped frames, worn hinges, and failed mechanisms are all signs that the window has reached the end of its useful life.

Modern windows come with multi-point locking systems that are far more safe than the single-point catches on older frames. Options like toughened glass provide additional security too.

Rising Energy Bills

A large proportion of heat loss in any house happens through the windows. They act as the barrier between your living space and the outside weather.

Double glazing from years ago is a thing of the past, and the energy ratings will be well below what’s achievable today, even if the spec was decent when first fitted.

Protect your home from rising energy costs. New double glazed windows and doors make the difference.

Advanced Group's range of double glazed windows in Showroom

Window Types Available in Drongan

The right window type for your Drongan house will depend on the property itself, the room in question, and how you live in it.

The Advanced Group provides and installs a full selection 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 types.

casement-product-image

Classic Casement Windows

Possibly the most common window style in the UK, casement windows are side-hinged and open outwards, which makes them practical for ventilation and easy to clean from inside.

Ideal for most property kinds, from modern homes to traditional properties, casement windows are offered in a wide selection of colours and finishes, including woodgrain effects that replicate the appearance of timber without the maintenance or worry of warping.

Sash windows vs Casement Windows

Sliding Sash Windows

Like the appearance of original wooden sash frames? Our sliding sash windows mirror that classic appearance while providing modern thermal efficiency and security.

Proportions, sight lines, and opening mechanism all match the traditional look. Ideal for conservation areas or preserving your property’s charm.

tilt and turn windows dundee

Practical Tilt and Turn Windows

These 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 fix that problem completely.

The tilt function delivers airflow without security concerns. Especially valuable for families with young children.

Top Hung Windows

About Top Hung Windows

Hinged at the top, opening outward from the bottom. Practical for ventilation and good at keeping rain out.

They are frequently installed in bathrooms, kitchens, stairwells, bay window setups, and other spaces where privacy and airflow are equally valued.

french-windows

French Windows Explained

French windows are full-length windows that open outward in the same way as French doors.

They’re perfect in pairs and can be matched with sidelights to fill a wide opening with glass and natural light.

uPVC Windows and Double Glazing in Drongan

We focus in uPVC frame materials. And for sound reason.

Scottish weather is harsh, and uPVC is designed to be long-lasting and tough to harsh, windy, and wet weather. Unlike timber frames, uPVC won’t have the same warping or rot issues.

And here’s another benefit: uPVC is really low maintenance!

Simply wipe it down with soapy water and it can look good as new.

Energy performance is where our uPVC windows truly stand out. Multi-chambered uPVC design, U-values as low as 0.8 W/m2K on some frames, and a real boost to the energy performance of your property.

The best part? uPVC double glazing is the most budget-friendly option available.

Higher-spec glazing without breaking the budget? That’s what uPVC offers. We also stock glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.

Energy Performance for Drongan Homeowners

Scotland is cold, wet, and windy for a good chunk of the year.

In such a weather pattern, the energy rating of your windows has a noticeable impact on your heating spend and the overall warmth of your home day to day.

Ever heard of U-values? That’s how the thermal efficiency of any window is measured.

Lower figure, less heat lost. Scottish building regulations currently set a maximum of 1.6 W/m2K for replacement windows.

Our standard double glazed windows deliver 1.2 W/m2K, and our premium options can hit 0.8 W/m2K! That’s performance at twice the regulatory minimum!

You’ll spot the difference on your energy costs.

A-rated windows and doors. Argon gas filled sealed units. Low-E glass coatings. Heat pushed back in, light still flowing through.

Old single-glazed sash windows or 1990s double glazing? Upgrade them, and you could see a significant drop in heating costs before the first winter is done.

Drongan has no shortage of double glazing firms. Few rival the quality of our windows and doors.

triple-glazed-windows

When Triple Glazing Is Worth It

We get asked about triple glazing regularly.

The additional pane of glass in triple glazing helps it to provide enhanced insulation and improved noise dampening.

If your property is in an exposed spot, up a hill, facing north, or near a busy road or flight path, The Advanced Group is more than pleased to guide you through the benefits of triple glazing.
