Spotted a temperature change in your home? Heating bills on the increase? Or condensation appearing on or inside your windows first thing?
Does that ring true? Your windows are telling you something’s.
As windows wear, they gradually lose their seal.
Gas seeps out from between the panes. The rubber gaskets harden and shrink. What once did stop the cold now barely registers.
Glenrothes’s rain and wind can feel more frequent than the sun. Worn windows make a noticeable difference to how warm and comfortable your house feels.
However not to worry, The Advanced Group is here to assist with over 38 years of trusted experience. Whether you want new windows for a single room or a full house of replacement windows and doors, we can point you towards the right option and get everything fitted properly.

Some problems are obvious. Cracked glass, rotten timber frames, handles that won’t fasten properly.
Some signs slip under the radar however, and by the time you notice them, they’ve been silently losing you money for months or even years.

Moisture or fogging between the two sheets of glass is a classic sign. The sealed unit has broken down.
Once the seal has failed, the argon gas that delivers insulation seeps away, and the window loses a substantial chunk of its thermal efficiency.
Why waste money away on rising heating bills? Recover your home’s thermal efficiency with perfectly sealed new windows instead.

Put your hand near the edges of the window on a windy day. If you can feel cold air sneaking in, the seals have worn.
Draught proofing strips can help in the short term, but they’re a sticking plaster on a issue that will only deteriorate as the rubber continues to break down.

Windows that stick, won’t close correctly, or refuse to budge are both a security risk and an insulation problem. Warped frames, worn hinges, failed mechanisms. The window has hit the end of its useful life.
Multi-point locking systems outperform the old single-point catches for protection. Toughened glass provides another layer of security.

Did you know that windows account for a significant amount of heat loss in any house? They’re the bridge between your home and the outside elements.
Old double glazing doesn’t compare. The energy ratings are far below what’s available today, even if the original spec was good when first fitted.
High energy costs don’t have to be the norm. New double glazed windows and doors help shield your home and keep those costs down.

Glenrothes houses come in all forms, and the right window style depends on your building, the room, and how you live in it.
The Advanced Group supplies and fits a full choice 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 styles.

The casement window holds the crown of the UK’s most common style. Side-hinged and opening outwards, they’re great for ventilation and a breeze to clean from inside.
Casement windows suit most property kinds, from modern homes to traditional properties, and are offered in a wide choice of colours and finishes, including woodgrain effects that mimic the look of timber without the maintenance and worry of warping.

Our sliding sash windows mirror original wooden sash frames. Modern thermal performance and safety are built in as standard.
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 preserve its character.

Tilt and turn windows are genuinely clever! They tilt inward at the top for safe ventilation and swing fully inward on a side hinge for simple cleaning.
They’re particularly popular in upper-floor flats, where climbing up a ladder to clean the outside of the glass is not realistic.
Airflow without the safety worry of a fully open window. That’s what the tilt function delivers, and it’s particularly handy for families with young children.
Top hung windows are hinged at the top and open outward from the bottom, giving a practical choice for ventilation that also helps to keep rain out.
They’re often used in bathrooms, kitchens, stairwells, bay window arrangements, and other spaces where privacy and airflow are equally needed.

French windows are full-length windows that open outward like French doors.
Pair them up and match them with sidelights, and you can open up a wide opening with glass and natural light. The result is beautiful.

The Advanced Group specialises in uPVC frame materials for sound reasons.
Scottish weather is tough. uPVC is built to withstand it. Hardwearing, resilient to wild, windy, wet conditions. No warping or rot worries like timber.
Not only that, but uPVC is low maintenance.
Simply wipe it down with soapy water and it can look fresh.
Energy efficiency is where our uPVC windows truly stand out. Multi-chambered uPVC engineering, U-values as low as 0.8 W/m2K on some frames, and a proper boost to the energy efficiency of your home.
And you know the best part? uPVC double glazing is also the most affordable option out there!
That allows you can often opt for premium-grade glazing without breaking the budget. We also provide glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.
For a significant part of the year, Scotland’s climate is cold, wet, and windy.
That climate means the energy efficiency of your windows makes a difference. It affects how much you pay on heating and how warm your home feels from one day to the next.
U-value. That’s the number that shows you how thermally efficient a window really is.
A lower number means less heat getting out through the glass and frame. At present, Scottish building regulations require 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 the premium models can reach as low as 0.8 W/m2K. That’s double glazing and triple glazing operating at twice the level of the regulatory minimum.
That difference is directly shown on your energy costs.
A-rated energy-efficient windows and doors, fitted with argon gas filled sealed units and low-E glass coatings, work by reflecting heat back into the room while continuing to let light through.
If you’re upgrading from old single-glazed sash windows or 1990s double glazing, you could see a real drop in your heating costs within the first winter.
There are plenty of double glazing companies in Glenrothes selling standard products, but not many can rival the quality of what we provide.

Our trusted installers often get asked about our triple glazing products.
An extra pane of glass makes triple glazing apart. It means better insulation and improved noise control beyond standard double glazing.
Exposed spot. Up a hill. Facing north. Near a busy road or under a flight path. If any of those fits like your property, The Advanced Group is here to guide you through the advantages of triple glazing.
