Felt a temperature change in your home? Bills on the rise? Or condensation forming on or inside your windows first thing?

Sound familiar? Your windows are telling you a signal.

As windows wear, they lose their seal.

The gas between the panes gradually escapes, the rubber gaskets harden and pull back, and what used to blocked the cold out now scarcely makes any difference.

In a city like St Martins, where rain and wind can sometimes feel more frequent than the sun, worn windows make a real difference to how warm and pleasant your house feels.

The Advanced Group is here to help, backed by over 38 years of trusted service. Whether you are looking for new windows for a single room or a full house of replacement windows and doors, we’ll work with you to choose the right fit and ensure everything is installed properly.

Window Replacement

Signs It’s Time to Replace Your Windows

Some problems are obvious. Cracked glass. Rotten timber frames. Handles that won’t fasten right.

But other signs are easier to miss, and by the time you catch them, they’ve already been costing you money for months or even years.

Condensation Inside Double Glazing

Condensation Forming Between the Panes

If you can notice moisture or fogging between the two sheets of glass, the sealed unit has broken down.

Once the seal breaks, the argon gas that provides insulation leaks out, and the window loses a large portion of its thermal performance.

Why waste money away on increasing heating costs? Recover your home’s thermal performance with perfectly sealed new windows instead.

draught proofing

Noticing Draughts and Cold Spots

Place your hand near the edges of the window on a windy day. If you can feel cold air coming through, the seals have worn.

Draught proofing strips provide a short-term measure, but they’re essentially a sticking plaster on a issue that will only worsen as the rubber continues to break down.

Windows That Stick or Won’t Close

Windows that stick, won’t fasten properly, or refuse to budge are both a security risk and an insulation issue. Warped frames, worn hinges, failed mechanisms. The window has reached the end of its useful life.

Multi-point locking systems on today’s windows offer significantly greater security than the single-point catches fitted to older windows, and toughened glass options give an extra layer of security.

Are Your Energy Bills Too High?

Your windows are responsible for a considerable share of the heat loss in your property. They’re the bridge between you and the weather outside.

Double glazing from the past is exactly that, in the past. The energy ratings land far below current offerings, even if the original specification was reasonable when first installed.

Protect your house from rising energy costs. New double glazed windows and doors create the difference.

Advanced Group's range of double glazed windows in Showroom

Our Window Types for St Martins

Every St Martins property is different, and the right window style depends on the property, the room, and how you live in it.

The Advanced Group stocks and fits a complete range of windows and doors in double glazed and triple glazed configurations, including uPVC casement, sash, tilt and turn, and top hung types.

Sash windows vs Casement Windows

uPVC Casement Windows

As quite possibly the most common window style in the UK, casement windows are side-hinged and open outwards, providing effective ventilation and easy cleaning from inside.

Casement windows go with most property types. Modern homes, traditional villas, the lot in between. On offer in a wide range of colours and finishes, including woodgrain effects that deliver the look of timber without the maintenance or warping fear.

sash window security features

Sliding Sash Windows Overview

Our sliding sash windows are made to mirror the style of original wooden sash frames, while providing modern levels of thermal performance and protection.

Proportions, sight lines, and opening mechanism all mirror the traditional look. Great for conservation areas or preserving your property’s personality.

tilt and turn windows dundee

Tilt and Turn Window Style

These windows tilt inward at the top for protected ventilation and turn fully inward on a side hinge for simple cleaning.

They’re particularly well-liked in upper-floor flats, where getting up a ladder to clean the outside of the glass is not practical.

The tilt feature enables airflow without the safety concerns that come with a fully open window, which is especially useful for families with young children.

Top Hung Windows

About Top Hung Windows

Top hung windows are hinged at the top and open outward from the bottom, making them a smart choice for ventilation while working to keep rain out.

Bathrooms, kitchens, stairwells, bay window setups, anywhere privacy and airflow both count. That’s where top hung windows come into their own.

french-casement-white-1440x1624

Classic French Windows

French windows are full-length windows that open outward, working much like French doors.

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

uPVC doors and Windows

uPVC Double Glazing in St Martins

The Advanced Group concentrates in uPVC frame materials for strong reasons.

Scottish weather throws the lot at your windows. uPVC is designed to withstand it, tough, resilient to rough, windy, wet conditions, and free from the warping or rot issues that plague timber frames.

Not only that, but uPVC is low maintenance.

A brief wipe down with soapy water is all it takes to keep your uPVC windows looking fresh.

Energy performance is where our uPVC windows truly deliver. Multi-chambered uPVC engineering, U-values as low as 0.8 W/m2K on some frames, and a real improvement to the energy performance of your home.

And best of all? uPVC double glazing is also the most cost-effective option.

This means you can often install premium-grade glazing without exceeding the budget. We also stock glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.

Top Energy Rating - Edinburgh

Energy Efficiency and Heating Bills in St Martins

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

In that climate, the energy rating of your windows makes a real difference to how much you spend on heating and how pleasant your home feels day to day.

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

The lower that value, the less heat escapes through your glass and frame. Scottish building regulations currently require a maximum U-value of 1.6 W/m2K for replacement windows.

Our standard double glazed windows deliver 1.2 W/m2K, and our premium products can achieve values as low as 0.8 W/m2K. That’s top-performing double glazing and triple glazing that works twice as well as the regulatory minimum.

That difference is directly shown 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.

If you’re upgrading from old single-glazed sash windows or 1990s double glazing, you could spot a significant drop in your heating costs within the first winter.

A lot of double glazing businesses in St Martins offer standard products, but not many can rival the calibre of the windows and doors we supply.

Triple Glazing Aberdeen

When to Consider Triple Glazing

Our trusted installers often get asked about our triple glazing range.

Triple glazing packs in an extra pane of glass, which gives better insulation and clearly better noise control.

If your property is located in an exposed location, up a hill, facing north, or near a busy road or under a flight path, reach out! The Advanced Group would be more than pleased to guide you through the upsides of triple glazing.
