Our range of Eclipse aluminium windows tick every box when it comes to energy efficiency, durability and elegance.

Aluminium is an extremely strong material and this means it can be moulded to create slim frames. With the slender profile, TWC’s Eclipse aluminium windows have a large space for glazing. The high proportion of glazing will welcome maximum natural light into homes.

From traditional white finishes to wood effect finishes, you’ll be able to customise your Eclipse windows to your taste.

Eclipse Hinge

Our highly engineered hinge provides increased load bearing and features unique anti-crowbar technology, providing a lifetime of protection and reassurance. With 90 degree opening and Egress easy clean as standard, window maintenance has never been so simple.

Eclipse Glass

High performance, next generation glass offers excellent energy efficiency. With an ultra-clear outer pane, and a super soft coat inner pane as standard.

Eclipse Frame

A true declaration of style. Our low density, slimline frames are perfect for a clean, modern appearance, but are also built with the strength to withstand even the harshest of weather conditions.

Eclipse Locking

The sophisticated multi-point lock within the Envisage system ensures the window is fully secure when locked. Featuring our patented ‘Secure It’ mechanism, the window was tested over 30,000 times during the development stage.

Eclipse Weather Seal

Dual density and high elasticity for twice the coverage of standard windows. The Eclipse flush casement range boasts long lasting airtight protection from the elements and added noise reduction.
Offering a view that will continuously captivate

Eclipse has one of the slimmest aluminium window profiles ever created and it’s because of this that it carries so much glass.

All this glass makes for the most amazing view through an Eclipse window and will also see your home interior enriched with natural light.

We know that one-size doesn’t fit all so far as how each individual customer wants their Eclipse Aluminium Windows to look, so we will adapt it for you. You just let us know what finish, glazing and hardware you want, and we will deliver it.

Only with a powder-coated finish can you get such exuberant colours...

TWC firmly believes in the 11-stage powder-coating method that we employ when adding finishes to our Eclipse aluminium windows. When we undertake that process it causes strong paint adhesions to be induced and makes for the most wonderful of finishes. Sublimation is the act performed for those customers wanting a modern aluminium woodgrain. Available in Rosewood, Oak and Walnut, these woodgrains brilliantly mimic authentic woodgrains.

Choose your favoured type of glass...

The most common form of glazing chosen for replacement windows is plain glass, but there is a large audience for energy saving glass and privacy glass too. If maximising your energy savings is important to you, it makes sense to include energy saving glass, just as it would also be logical to request privacy glass should you want to enhance privacy levels at home.

The finest window hardware

Much of the charm of an Eclipse Aluminium Window stems from the handle used in the design - there are an array of handles to choose from.

Some of these handle styles are antiquated in their look, with others more up-to-date if you want to be a trend-setter, rather than a follower of tradition.

We know that finding the right windows for you is essential, and finding the right installer is even more important. We have over 30 years of combined experience transforming homes across Wiltshire and Oxfordshire, this includes installing our outstanding range of aluminium windows. With TWC Home Improvements you can trust that you’re getting the aluminium windows you want along with peace of mind thanks to our 20 year guarantee.
