An Eclipse aluminium frame is extremely slim, but don’t be fooled into thinking that it doesn’t offer the protection needed to keep your Cumbrian home secure. Together with the substantial piece of double or triple glazing it accommodates, you can rely on it to keep your possessions safe.
The other great thing about having such a huge pane of glass is that it will inevitably illuminate your interior far more than the previous window solution you had installed. You also have the luxury of being able to have your Eclipse aluminium windows decorated with a range of RAL powder-coated colours.

Over the past few years our Eclipse aluminium window range has rapidly expanded to accommodate demand for this extraordinarily reliable material. Aluminium really is in a league of its own when it comes to providing strength and durability.
You can’t fail to be impressed by how impressive the aluminium frame looks on the eye, predominantly due to the way it can be moulded to create sleek, slim and slender sightlines.


Explore our Eclipse Aluminium Windows
You’ll be amazed by the fantastic range of aluminium windows we have at Planet– we’re all about giving you plenty of options to find your perfect fit. Our aluminium range is called Eclipse. Pick the colour, glazing, and hardware that suit your style and make it truly yours. Every window is thoughtfully designed to combine elegance and strength, keeping your home cosy, secure, and looking its best.
Aluminium Casement Windows
Our aluminium casement windows are a shining example of this timelessly popular style, crafted with exceptional precision using premium materials. Trust Planet to create casements tailored to your preferred depth, size, and shape—showcasing the remarkable skill of our talented craftspeople.
Casement windows have a rich history spanning generations and remain a top choice for homeowners looking to upgrade their windows. Their classic side-hinged design allows for smooth outward opening, combining functionality with charm. Visit our Kendal showroom to see them up close and experience the quality firsthand.

Aluminium Flush Windows
Finding a suitable replacement for traditional flush casement windows might seem like a challenge, but it doesn’t have to be. At Planet, you’ll find Eclipse aluminium flush windows—a remarkably accurate replica of the classic design. Known for their perfectly flat exterior, flush windows have traditionally been crafted from authentic timber.
Despite their sleek appearance, Eclipse aluminium window frames boast exceptional durability. We believe there’s no better alternative to traditional timber windows—offering the same timeless look while significantly surpassing wooden frames in both security and insulation performance.

Aluminium Tilt & Turn Windows
Discover ultimate versatility with our tilt and turn aluminium window – where convenience meets smart design. A simple twist of the handle tilts the window inward from the top, letting in a gentle flow of fresh air while keeping safety a priority, especially for homes with young children.
Turn the handle fully, and the window opens wide from the side, giving you easy access for cleaning and seamless functionality. It’s a practical solution that makes life that little bit easier.

Aluminium Bay & Bow Windows
Bay and bow windows are unmistakable with their outward projection and arrangement of three or more panels. This iconic design adds depth and dimension to your interior spaces, making it a standout feature of any home.
Choose from rectangular, triangular, or polygonal panel configurations to create a bay and bow window that enhances your home’s exterior while offering a fresh perspective on the world outside.

Aluminium French Windows
French windows operate much like French doors, with two parallel-opening vents that create a wide, open space to welcome in natural light and fresh air. The generous light flow not only brightens your home but also gives it a more spacious feel.
This versatile opening style is perfect for days when you want to bring an outdoor ambiance into your indoor spaces. French windows are especially popular in kitchens, where they can even double as a convenient pass-through.

Aluminium Cottage Windows
Our aluminium cottage windows are a beautiful tribute to the heritage designs that once adorned period homes and historic properties. Combining timeless aesthetics with modern thermal efficiency and security, they’re a perfect choice for homes in conservation areas and equally suited to new builds.
Every detail has been carefully crafted to replicate the charm of traditional cottage windows, preserving their classic appeal while delivering the benefits of contemporary innovation.

Aluminium Shaped Windows
Traditional window designs might not fit every opening, but there’s no need to worry – we offer aluminium arched and custom-shaped windows. Whether your home is modern or classic, these unique designs can create a stunning focal point in the appropriate space.
Irregularly shaped windows often capture more natural light than conventional square or rectangular styles, bringing a brighter and more inviting atmosphere to any home that chooses them.

Aluminium Fixed Windows
To enhance a striking outdoor scene, consider aluminium fixed windows – a stationary option designed to elegantly showcase and highlight your view. With incredibly narrow aluminium frames, these windows allow for maximum glazing, offering an uninterrupted perspective of the outside world.
The robust quality of the aluminium frame ensures that our fixed windows resist the effects of weathering, retaining their timeless style throughout the entire warranty period.

Unmatched aluminium windows from a trusted window installer...
You truly have to see Eclipse aluminium windows in person at our Kendal showroom to fully appreciate their brilliance. The striking finishes are sure to catch your eye, thanks to the precise colouring techniques we use to apply our vibrant hues to the frames.
Once Eclipse aluminium windows are installed in your home, your rooms will feel noticeably more inviting. You’ll also experience a boost in warmth, thanks to the exceptional insulating properties of the frames.

Eclipse aluminium windows security
Windows play a crucial role in your home’s overall security, something we at Planet take seriously. Eclipse aluminium windows are equipped with a range of security-focused features. Let us walk you through some of them.

Cranked Window Handles
Operating your aluminium windows will actually be enjoyable, thanks to the ergonomically shaped handles we have created.

Window Hinge Bolts
The main reason for the hinge bolts is to ensure the hinge side of the sash remains securely fixed so there is much less of a risk of forced entry.

Herculean Window Hinges
Smooth functionality is guaranteed, thanks to the heavy-duty anti-weathering hinges, and you can expect no buildup of wear and tear.

Multi Locking Mechanisms
Intruders will find it frustrating to discover that aluminium windows are equipped with a multi-point locking mechanism, rendering break-in attempts pointless.
Premium window accessories bespoke to you
You have the freedom to make Eclipse aluminium windows your own, creating a unique look that stands out from your neighbours. Personalise the colour, glazing, and hardware, carefully considering the perfect finishing touches, and share your preferences with us.
Striking shades and captivating tones...
The colour options for aluminium windows are far more diverse these days—at least they are at Planet. In addition to timeless favourites like white and grey, you can choose from an array of powder-coated finishes, all displayed in our extensive colour palette.
If you’re a fan of timber windows, our woodgrain finishes will undoubtedly catch your eye. They’re incredibly realistic, with a texture that even feels like wood.
Premium handles...
Eclipse aluminium windows come with a dedicated range of handles designed to complement this premium collection. Our handles offer excellent security and smooth functionality, all while being visually appealing.
If you’re unsure which handle pairs best with your chosen window style, don’t hesitate to consult one of our advisors. At Planet, we’re committed to offering knowledgeable and reliable advice.
Bold handle finishes to highlight the quality...
As you browse through our handle catalogue, take note of the different finishes available for each one and consider which will best complement your window design. The colour options are divided into two categories – traditional and modern.
While most customers choose to match the handle colour with the window frames, there’s no reason you can’t create a striking contrast between the two for a unique look.
Smart glazing options for superior performance...
Replacement Eclipse aluminium windows enhance thermal efficiency thanks to the combination of their insulating framework and clever glazing. The glass helps trap external heat inside, significantly reducing heat loss.
While highly functional, the glazing selected for the Eclipse range is also exceptionally stylish. If you require privacy glazing for some of your new windows, just let us know—we can ensure your rooms remain protected from view.
Astragal, Georgian or leaded bars...
If you feel that plain Eclipse windows are too simple and want to add a touch of detail, leaded, astragal, or Georgian bars can provide the perfect decorative enhancement. These classic features will elevate the appeal of your Eclipse windows, adding timeless charm.
For those with a traditional taste, these decorative bars will bring an extra layer of personality and character. We can even show you a digital visualisation of the bar detailing on Eclipse windows using our design software, so you can see exactly how it will look.

Did you know our windows & doors come with a 20 year guarantee?
That’s double what most other double glazing companies offer for their windows & doors – giving you total peace of mind.
Have you explored our front & back doors to complement your new aluminium windows?
New aluminium windows deserve doors that live up to the same standard. Our stylish front and back doors are designed to complement your new aluminium windows perfectly – offering a seamless look, improved energy efficiency, and enhanced security across your entire home.
