If you’ve noticed a temperature shift in your home, or spotted your bills rising, or condensation appearing on or inside your windows in the morning, it’s worth taking notice.
That nagging feeling? It’s your windows signalling to you they need attention.
Older windows lose their seal over time.
The gas between the panes seeps out, the rubber gaskets go hard and pull back, and what once blocked the cold now hardly does anything.
In a city like Crown, where rain and wind are frequently more regular than sunshine, ageing windows have a real impact on how warm and pleasant your home feels.
Not to worry. The Advanced Group brings over 38 years of trusted service. Single room or full house, replacement windows or doors, we’ll find the right solution and fit everything right.

Some problems are obvious. Cracked glass. Rotten timber frames. Handles that won’t fasten right.
But then there are the sneakier signs. The ones you overlook until they’ve already been draining you money for months, maybe years.

Can you spot moisture or fogging sitting between the two sheets of glass? That means the sealed unit has given way.
When the seal fails, the argon gas that provides insulation leaks, and the window loses a considerable portion of its thermal performance.
Increasing heating bills don’t have to keep climbing. Properly sealed new windows will recover your home’s thermal performance and start to bring those bills back down.

A windy day reveals you all you need to know. Place your hand near the edges of the window. Cold air coming through tells you the seals have deteriorated.
Draught proofing strips give you time, but they’re a sticking plaster at best. The rubber keeps degrading, and the problem only grows.

Windows that stick, bind, or won’t fasten properly are a security risk as well as an insulation issue. Warped frames, worn hinges, and failed mechanisms all point to the window has come to the end of its functional life.
The single-point catches on older windows can’t compete with the multi-point locking systems on modern windows. Factor in toughened glass, and your property has a real protection improvement.

A considerable amount of heat loss in any home occurs through the windows. They represent the bridge between your living space and the outside weather.
Your old double glazing? It’s had its day! The energy ratings are well below what’s available now, even if the original specification was good when first installed.
New double glazed windows and doors will protect your property from high energy costs.

The right window choice for your Crown home will depend on the property itself, the room in question, and how you live in it.
The Advanced Group supplies and fits a full selection of windows and doors in both double glazed and triple glazed options, including uPVC triple and double and triple glazed casement, sash, tilt and turn, and top hung styles.

Casement windows are probably the UK’s most popular window type! They’re side-hinged, open outwards, and are great for ventilation and simple to clean from inside.
They complement most kinds of property, from modern builds to traditional properties, and are available in a wide choice of colours and finishes. Woodgrain effects replicate the look of timber without the maintenance or fear of warping.
Like the look of original wooden sash frames? Our sliding sash windows recreate that original look while packing in modern thermal performance and security.
The proportions, sight lines, and opening mechanism are all made to match the traditional style, which is particularly relevant if your property is in a conservation area or you wish to maintain its character.

Tilt and turn windows are really handy! They tilt inward at the top for safe ventilation and swing fully inward on a side hinge for easy cleaning.
They’re especially common in upper-floor flats, where getting up a ladder to clean the outside of the glass is not practical.
The tilt function allows air in without the safety worries of having the window wide open, which is particularly useful if you’ve got young children.

Hinged at the top, opening outward from the bottom. Sensible for ventilation and great at keeping rain out.
They’re often used in bathrooms, kitchens, stairwells, bay window configurations, and other spaces where privacy and airflow are just as needed.

French windows are full-length units that open outward just like French doors.
They perform well in pairs and can be combined with sidelights to cover a wide opening with glass and natural light.

The Advanced Group focuses in uPVC frame materials, and for very good reasons!
Scottish weather can be harsh, but uPVC withstands 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 come with.
And here’s one more bonus: uPVC is seriously low maintenance!
A simple wipe down with soapy water is all it needs to keep your uPVC windows looking brand new.
Perhaps most importantly, our uPVC windows offer impressive levels of energy efficiency. Designed with multi-chambered uPVC, some of our frames attain a U-value as low as 0.8 W/m2K, helping to bring back energy efficiency in your home.
And you know the best news? uPVC double glazing is also the most budget-friendly option out there!
So you can often install premium-grade glazing and still stay within budget. We provide glazed uPVC doors too, including uPVC doors, composite doors, and patio doors to coordinate.
Scotland’s weather is cold, wet, and windy for a good chunk of the year.
In that type of weather, the energy performance of your windows genuinely affects how much you pay on heating and how cosy your house feels day to day.
A window’s thermal efficiency is measured by what’s known as its U-value.
The lower that value, the less heat escapes through your glass and frame. Scottish building regulations currently set a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows come in at 1.2 W/m2K, and our premium range can hit 0.8 W/m2K! That’s performance at twice the regulatory minimum!
The evidence? It lands on your energy costs.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings are amazing at sending heat back into the room while still letting loads of light through.
If you’re upgrading from old single-glazed sash windows or early double glazing from the 1990s, you could see a genuinely significant drop in your heating bills within even the first winter!
Crown has a good number of double glazing firms. Few come close to the standard of our windows and doors.
Our experienced installers enjoy chatting about triple glazing, and it’s a question that arises a lot!
An extra pane of glass sets triple glazing apart. It delivers stronger insulation and greater noise reduction over standard double glazing.
If your property is in an exposed position, at a raised altitude, facing north, or near a busy road or flight path, The Advanced Group would be more than pleased to walk you through the benefits of triple glazing.

New windows are an investment, and we know that paying for them all at once isn’t always realistic.
That’s why we provide 0% APR and up to 4 years of interest free credit.
The windows you deserve, with the cost spread in a way that suits for you. That’s what 0% finance allows.
