Maybe you’ve spotted a change in temperature in your house. Bills rising. Or condensation sitting on or inside your windows in the morning.
Sound familiar? Your windows are sending you a clear sign.
As windows wear, they gradually lose their seal.
The gas between the panes gradually leaks, the rubber gaskets stiffen and shrink, and what used to blocked the cold out now barely holds it back.
In Renfrew, where the rain and wind can appear more frequent than sunshine, ageing windows really affect how warm and cosy your home feels.
But there’s no need to worry, The Advanced Group is here to lend a hand with more than 38 years of trusted experience. Whether it’s new windows for one room or a full house of replacement windows and doors, we’ll find you the right fit and get everything fitted correctly.

Some problems are easy to spot. Cracked glass, rotten timber frames, handles that don’t close correctly.
But other signs are easier to miss, and by the time you catch them, they’ve already been losing you money for months or even years.

Noticing moisture or fogging between your two sheets of glass indicates the sealed unit has broken down.
The seal goes. The argon gas leaks out. The window loses a major portion of its thermal efficiency.
Don’t let rising heating prices drain your budget. Restore your home’s thermal efficiency by installing properly sealed new windows.

A windy day shows you a lot. Put your hand near the edges of the window. Cold air getting through means the seals have gone.
Draught proofing strips offer you time, but they’re a sticking plaster at best. The rubber keeps perishing, and the fault only grows.

Windows that stick, won’t fasten correctly, or refuse to budge are both a safety risk and an insulation problem. Warped frames, worn hinges, failed mechanisms. The window has reached the end of its functional life.
Modern windows feature multi-point locking systems that are far more safe than the single-point catches on older models. Options like toughened glass add further security too.
Windows are responsible for a considerable amount of heat loss in any home. Your window is the bridge between you and the outside weather.
Double glazing from years ago is old news, and the energy ratings will be significantly below what’s achievable now, even if the spec was decent when first fitted.
New double glazed windows and doors will guard your property from high energy costs.

Every Renfrew property has its own feel. The right window type depends on the building, the room, and how you use it.
A full range of windows and doors, double glazed and triple glazed, is ready from The Advanced Group, including uPVC casement, sash, tilt and turn, and top hung styles, all supplied and fitted by our installers.

Quite likely the most popular window style in the UK, casement windows are side-hinged and open outwards, which makes them great for ventilation and straightforward to clean from inside.
Casement windows suit most property types, from modern houses to traditional properties, and are provided in a wide range of colours and finishes, including woodgrain effects that replicate the look of timber without the maintenance and fear of warping.

Our sliding sash windows look like original wooden sash frames. Modern thermal efficiency and protection are built in as standard.
The proportions, sight lines, and opening mechanism all match the traditional style, which matters if your property is in a conservation area or you simply want to preserve its charm.

Tilt and turn windows are genuinely clever! They tilt inward at the top for protected ventilation and swing completely inward on a side hinge for easy cleaning.
They’re a popular choice for upper-floor flats where cleaning the outside of the glass from a ladder isn’t an option.
The tilt feature lets air in without the safety concerns of having the window fully open, which is especially handy if you’ve got young children.
Top hung windows hinge at the top and open outward from the bottom. This makes them a sensible choice for ventilation while helping to hold rain out.
They are frequently fitted in bathrooms, kitchens, stairwells, bay window arrangements, and other spaces where privacy and airflow are equally important.

French windows are full-length units that open outward, working in the same way as French doors.
In pairs, they work fantastic, and you can match them with sidelights to open up a wide opening with glass and lots of natural light.
The Advanced Group’s focus is uPVC frame materials, and this decision is backed by solid reasons.
Scottish weather can be harsh, but uPVC handles it all! It’s hardwearing, resists wind, rain, and the roughest of it, and you won’t get the warping or rot issues that timber frames come with.
Not only that, but uPVC is low maintenance.
Just a simple wipe with soapy water and it looks as good as new!
Perhaps most significantly, our uPVC windows offer strong levels of energy performance. Built with multi-chambered uPVC, some of our frames achieve a U-value as low as 0.8 W/m2K, working to restore energy performance throughout your house.
And best of all? uPVC double glazing is also the most budget-friendly option.
This allows you to often choose premium-grade glazing without blowing your budget. We also provide glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.
Scotland’s weather is cold, wet, and windy for a large part of the year.
In that sort of weather, the energy efficiency of your windows truly influences how much you pay on heating and how warm your house feels day to day.
A window’s thermal efficiency is measured by what’s known as its U-value.
A lower value means less heat escaping through the glass and frame. Currently, Scottish building regulations 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 good as the regulatory minimum.
And where does that difference show up? Right on your energy costs!
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings are brilliant at sending heat back into the room while still letting loads of light through.
If you’re swapping out old single-glazed sash windows or dated double glazing, you could notice a significant drop in your heating bills within the first winter.
Renfrew has its share of double glazing companies, and most supply entry-level products. Few, though, match the calibre of the windows and doors supplied by The Advanced Group.

Our trusted installers enjoy chatting about triple glazing, and it’s a question that comes up frequently!
An extra pane of glass sets triple glazing apart. It translates to enhanced insulation and improved noise dampening over standard double glazing.
If your property is in an exposed position, at a high altitude, facing north, or close to a busy road or flight path, The Advanced Group would be more than happy to walk you through the benefits of triple glazing.
