New Windows Castlehill
Quality Energy Efficient Double Glazed Windows & Doors




Maybe you’ve felt a drop in temperature inside your home. Energy bills rising. Or condensation building up on or inside your windows each morning.
If any of that rings familiar, your windows are trying to tell you something.
Windows don’t last forever, and older ones drop theirs over time.
The gas between the panes seeps away, the rubber gaskets harden and pull away, and what once did hold the cold out now barely makes a difference.
In Castlehill, where the rain and wind can seem more regular than sunshine, ageing windows definitely change how warm and comfortable your house feels.
No need to stress about it! The Advanced Group has been helping homeowners for over 38 years. Whether you need new windows for just one room or every room of replacement windows and doors, we’ll guide you to the right choice and get it all fitted properly.

Some issues are plain to see. Cracked glass. Rotten timber frames. Handles that won’t fasten correctly.
Other signs are harder to catch. By the time you do, they’ve been costing you money for months or years.

Moisture or fogging between the two sheets of glass is a classic sign. The sealed unit has broken down.
Once the seal has gone, the argon gas that provides insulation seeps away, and the window loses a significant amount of its thermal efficiency.
Increasing heating bills don’t have to eat into your wallet. Bring back your home’s thermal performance with perfectly sealed new windows.

Try a quick test: place your hand near the edges of the window on a windy day. If cold air is coming through, the seals have worn out.
Sure, draught proofing strips can help for a bit, but they’re honestly a sticking plaster. The fault only worsens as the rubber keeps degrading.

Windows that stick, won’t lock properly, or refuse to open are both a safety risk and an insulation concern. Warped frames, worn hinges, failed mechanisms. The window has come to the end of its functional life.
Multi-point locking systems on today’s windows offer far better protection than the single-point catches used in older windows, and toughened glass options provide an further layer of safety.
Did you know that windows account for a significant amount of heat loss in any home? They’re the link between your house and the outside world.
If your double glazing is dated, the energy ratings will almost always be well below what’s on offer today, even if they were a good specification when first installed.
Fitting new double glazed windows and doors is one of the most effective ways to shield your property from high energy costs.

Every Castlehill property has its own personality. The right window type hinges on the property, the room, and how you live in it.
The Advanced Group provides a full choice of windows and doors in both double glazed and triple glazed configurations, including uPVC casement, sash, tilt and turn, and top hung designs.

Quite likely the most popular window style in the UK, casement windows are side-hinged and open outwards, which makes them practical for ventilation and straightforward to clean from inside.
Modern home or traditional villa, casement windows work with the lot. A wide selection of colours and finishes is available, and the woodgrain effects capture the look of timber without any of the maintenance or warping worries.

Our sliding sash windows are made to replicate the style of original wooden sash frames, while offering modern standards of thermal performance and protection.
The proportions, sight lines, and opening mechanism all stay true to the traditional look, which is brilliant if your property’s in a conservation area or you just want to hold onto its character.

Tilt them inward at the top for secure ventilation. Turn them fully inward on a side hinge for easy cleaning. Two functions, one window.
They’re especially well-liked in upper-floor flats, where getting up a ladder to clean the outside of the glass is not realistic.
The tilt mode provides you airflow without the safety risks of a fully open window, which is particularly useful for families with young children.
Top hung windows are hinged at the top and open outward from the bottom, making them a sensible choice for ventilation while working to keep rain out.
You’ll find top hung windows in bathrooms, kitchens, stairwells, and bay window arrangements, basically anywhere that privacy and airflow are both needed.

French windows are full-length units that open outward, operating in the same way as French doors.
In pairs, they work fantastic, and you can combine them with sidelights to flood a wide opening with glass and plenty of natural light.
The Advanced Group’s focus is uPVC frame materials, and this decision is backed by good reasons.
Scottish weather can be rough, but uPVC withstands it all! It’s hardwearing, stands up to wind, rain, and the harshest of it, and you won’t get the warping or rot problems that timber frames come with.
Not only that, but uPVC is low maintenance.
Simply wipe it down with soapy water and it can look brand new.
The real benefit? Energy efficiency. Our uPVC windows feature multi-chambered uPVC, and some frames hit a U-value as low as 0.8 W/m2K. That recovers proper energy performance to your home.
And the better part? uPVC double glazing happens to be the most affordable option on the market.
This means you can often install higher-spec glazing without blowing the budget. We also supply glazed uPVC doors, including uPVC doors, composite doors, and patio doors to complement.
Cold, wet, and windy. That’s Scotland for a good chunk of the year.
That climate means the energy rating of your windows makes a difference. It influences how much you pay on heating and how comfortable your property feels from one day to the next.
The thermal performance of a window is assessed by its U-value.
The lower that figure goes, the less heat gets through. Scottish building regulations require the maximum at 1.6 W/m2K for replacement windows right now.
Standard double glazed windows: 1.2 W/m2K. Premium models: as low as 0.8 W/m2K. That’s twice as good as the regulatory minimum.
You’ll spot the difference on your energy costs.
A-rated energy-efficient windows and doors, equipped with argon gas filled sealed units and low-E glass coatings, work by reflecting heat back into the room while still managing to let light through.
Old single-glazed sash windows or 1990s double glazing? Upgrade them, and you could see a noticeable drop in heating spend before the first winter is done.
While many double glazing companies in Castlehill offer standard products, few can match the quality of the windows and doors we provide.

Our trusted installers often get asked about our triple glazing options.
Triple glazing has an extra pane of glass, allowing it to provide enhanced insulation and greater noise control.
Exposed area? Up a hill? Facing north? Near a busy road or flight path? The Advanced Group will talk you through the advantages of triple glazing.

New windows are an investment. Paying for them all at once? Not always realistic. We get that.
So we offer 0% APR and up to 4 years of interest free credit. Straightforward.
The windows you need, with the cost spread in a way that suits for you. That’s what 0% finance allows.
