We’ve installed thousands of windows over the last 34 years, take a look at what we have installed more recently.

New Windows Parkgate
Quality Energy Efficient Double Glazed Windows & Doors




Perhaps you’ve picked up on a change in temperature in your home. Bills going up. Or condensation forming on or inside your windows in the morning.
That nagging feeling? It’s your windows telling you they need attention.
As windows get older, they lose their seal.
The gas between the panes seeps away, the rubber gaskets stiffen and pull away, and what used to hold the cold out now barely holds it back.
Parkgate’s rain and wind can seem more common than the sun. Ageing windows make a clear difference to how warm and cosy your home feels.
The Advanced Group is here to help, bringing 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’ll work with you to choose the right fit and make sure everything is fitted the right way.

Some problems are straightforward, like cracked glass, rotten timber frames, and handles that don’t fasten the right way.
But other signs are easier to miss, and by the time you spot them, they’ve probably already been losing you money for months, sometimes even years.

If you can see moisture or fogging between the two panes of glass, this is a sure sign that the sealed unit has broken down.
The seal fails. The argon gas leaks out. The window loses a significant amount of its thermal efficiency.
Don’t keep pouring money away on increasing heating prices. Recover your home’s thermal efficiency with properly sealed new windows.

Hold your hand near the window edges on a windy day. Cold air getting through? The seals have worn away.
Draught proofing strips give a short-term fix, but they’re really a sticking plaster on a issue that will only deteriorate as the rubber keeps perish.

Seizing windows that won’t close properly aren’t just annoying, they’re a security risk and an insulation problem too. Warped frames, worn hinges, and failed mechanisms all point to a window that’s hit the end of its useful life.
Multi-point locking systems on today’s windows offer significantly stronger security than the single-point catches used in older frames, and toughened glass choices give an additional layer of safety.
Did you know that windows account for a significant share of heat loss in any home? They’re the link between your home and the outside world.
Double glazing from years ago is a thing of the past, and the energy ratings will be well below what’s achievable now, even if the specification was decent when first installed.
High energy costs don’t have to be the standard. New double glazed windows and doors help shield your property and keep those bills down.

No two Parkgate houses are the alike, and the best window style hinges on the property, the room, and how you live in it.
The Advanced Group supplies and fits a full selection of windows and doors in double glazed and triple glazed configurations, including uPVC casement, sash, tilt and turn, and top hung types.

Perhaps the most common window type in the UK, casement windows are side-hinged and open outwards, which makes them ideal for ventilation and simple to clean from inside.
Casement windows work with most property styles, from modern homes to traditional villas, and are offered in a wide selection of colours and finishes, including woodgrain effects that mimic the look of timber without the maintenance and risk of warping.

Our sliding sash windows mirror original wooden sash frames. Modern thermal performance and protection are included as standard.
Every proportion, sight line, and opening mechanism matches the traditional style. Whether your property is in a conservation area or you simply want to maintain its charm, these windows do the job.

These windows tilt inward at the top for protected ventilation and turn fully inward on a side hinge for easy cleaning.
Well-liked in upper-floor flats. Cleaning the outside from a ladder? Not an option.
The tilt feature is a real benefit! You get airflow without the security concerns of a fully open window, which is especially great if you’ve got young ones at home.
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 much like French doors.
Paired together, they work brilliantly and can be matched with sidelights to cover a wide opening with glass and natural light.
The Advanced Group’s focus is uPVC frame materials, and this choice is backed by sound reasons.
Scottish weather is tough. uPVC is designed to withstand it. Durable, tough to harsh, windy, wet conditions. No warping or rot concerns like timber.
Beyond that, uPVC provides the advantage of being low maintenance.
Wipe it down with soapy water. Job done. It looks as good as new.
More to the point however, our uPVC windows are highly energy efficient. With multi-chambered uPVC construction, some of our frames can achieve a U-value as low as 0.8 W/m2K, working to improve your home’s energy performance.
And better of all? uPVC double glazing is also the most affordable option.
That allows you can often choose premium-grade glazing without breaking the budget. We also carry glazed uPVC doors, including uPVC doors, composite doors, and patio doors to match.
For a significant portion of the year, Scotland’s climate is cold, wet, and windy.
With a climate like that, the energy rating of your windows makes a real difference to what you pay on heating and how pleasant your house feels every day!
The thermal efficiency of a window is measured by its U-value.
A lower U-value translates to less heat getting out through the 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 deliver 1.2 W/m2K, and our premium models can achieve values as low as 0.8 W/m2K. That’s superior double glazing and triple glazing that works twice as well as the regulatory minimum.
That difference is visually visible on your energy bills.
A-rated windows and doors. Argon gas filled sealed units. Low-E glass coatings. Heat reflected back in, light still getting through.
If you’re swapping out old single-glazed sash windows or dated double glazing, you could notice a noticeable drop in your heating spend within the first winter.
Many double glazing companies in Parkgate offer basic products, but few can compete with the calibre of the windows and doors we install.

We get asked about triple glazing all the time.
With an extra pane of glass, triple glazing offers enhanced insulation and greater noise reduction.
If your property is in an exposed area, at a raised altitude, facing north, or close to a busy road or flight path, The Advanced Group would be more than glad to guide you through the advantages of triple glazing.

We recognise that new windows represent a considerable purchase, and paying for them in full all at once isn’t always realistic.
0% APR. Up to 4 years interest free credit. That’s what we offer.
This lets you get the windows you want by spreading the cost of your new windows and doors in a way that fits around your budget.
