New Windows Bonnyrigg
Quality Energy Efficient Double Glazed Windows & Doors




A drop in temperature inside the home. Rising heating costs. Condensation sitting on or inside the windows each morning. Sound familiar?
If that sounds like your home, your windows are sending you a clear signal.
As windows wear, they start to lose their seal.
The gas between the panes seeps away, the rubber gaskets stiffen and shrink, and what once did block the cold out now barely holds it back.
Bonnyrigg gets its fair share of rain and wind, frequently more than sunshine. When your windows are past their best, you feel the difference in how warm and cosy your house is.
But not to worry, The Advanced Group is here to assist with over 38 years of trusted service. 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 installed correctly.

Some issues are hard to miss. Cracked glass. Rotten timber frames. Handles that don’t close correctly.
But other signs are harder to spot, and by the time you notice them, they’ve already been losing you money for months or even years.

Spotting moisture or fogging between your two panes of glass tells you the sealed unit has given up.
The seal goes, and with it escapes the argon gas that kept the insulation. The window loses a significant portion of its thermal efficiency.
Why throw money away on climbing heating prices? Bring back your home’s thermal performance with well sealed new windows today.

Place your hand near the window edges on a windy day. Cold air getting through? The seals have gone.
Draught proofing strips offer a short-term measure, but they’re just a sticking plaster on a fault that will only worsen as the rubber continues to perish.

A window that sticks, won’t close right, or refuses to budge is more than an annoyance. It’s a security risk and an insulation concern. Warped frames, worn hinges, and failed mechanisms are the window’s way of telling you it’s done.
Modern windows come with multi-point locking systems that are significantly more secure than the single-point catches on older frames. Options like toughened glass give additional security too.

A large proportion of heat loss in any home happens through the windows. They act as the barrier between your internal space and the outside elements.
Double glazing from the past is just that, in the past. The energy ratings sit significantly below current options, even if the original spec was solid when first installed.
Installing new double glazed windows and doors is one of the most effective ways to protect your home from high energy costs.

The right window type for your Bonnyrigg home will depend on the building itself, the room in question, and how you occupy it.
The Advanced Group offers and fits a full range 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.
Casement windows are likely the most popular window type in the UK. They’re side-hinged and open outwards, making them ideal for ventilation and simple to clean from inside.
Modern house or traditional house, casement windows complement the lot. A wide range of colours and finishes is on offer, and the woodgrain effects capture the look of timber without any of the maintenance or warping fear.

Our sliding sash windows are crafted to mirror the style of original wooden sash frames, while offering modern standards of thermal performance and protection.
The proportions, sight lines, and opening mechanism match the traditional design. That’s important if your property is in a conservation area or you just want to maintain its personality.
These windows give two functions: tilting inward at the top for safe ventilation, and turning completely inward on a side hinge for easy cleaning.
Upper-floor flat? Cleaning outside glass from a ladder isn’t practical. Tilt and turn windows solve that issue straight away.
The tilt feature gives airflow without safety worries. Especially valuable for families with young children.
Hinged at the top, swinging outward from the bottom. Top hung windows offer you ventilation and work to block the rain out at the same time.
Often used in bathrooms, kitchens, stairwells, and bay window configurations. Any space where privacy and airflow both count.

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

The Advanced Group concentrates in uPVC frame materials, and for really good reasons!
uPVC frame materials are especially well suited to the demanding Scottish weather, providing durability and resilience to rough, windy, and wet weather. Unlike timber frames, uPVC won’t suffer from the same warping or rot issues.
uPVC is low maintenance too.
Simply wipe it down with soapy water and it can look brand new.
Here’s the really big part: our uPVC windows are seriously energy efficient! Designed with multi-chambered uPVC, some of our frames reach a U-value as low as 0.8 W/m2K, which genuinely helps boost your home’s energy performance.
Best of all? uPVC double glazing is the most affordable option.
That means you can often upgrade to premium-grade glazing without blowing the budget! We also carry glazed uPVC doors, including uPVC doors, composite doors, and patio doors to coordinate.

Scotland is cold, wet, and windy for a significant chunk of the year.
With that weather, your windows’ energy performance genuinely impacts your heating costs and how warm your home feels daily.
U-value. That’s the number that reveals you how effective a window truly is.
The lower the number, the less heat gets out through the glass and frame. Scottish building regulations currently demand a maximum U-value of 1.6 W/m2K for replacement windows.
Our standard double glazed windows perform 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.
The difference appears on your energy statements.
A-rated energy-efficient windows and doors with argon gas filled sealed units and low-E glass coatings are brilliant at reflecting heat back into the room while still allowing 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 real drop in your heating spend within the first winter.
There are plenty of double glazing companies in Bonnyrigg selling entry-level products, but not many can rival the standard of what we provide.

Our trusted installers welcome talking about triple glazing, and it’s a question that arises a lot!
Triple glazing has an extra pane of glass, allowing it to provide better insulation and better noise levels.
If your home is in an exposed area, up a hill, facing north, or near a busy road or flight path, The Advanced Group is more than happy to guide you through the benefits of triple glazing.

We appreciate that new windows are an investment, and paying for them all at once isn’t always feasible.
That’s why we have 0% APR and up to 4 years of interest free credit.
It means you can get the windows you deserve by helping you spread the cost of your new windows and doors in a way that works for you.
