• Flush Style Windows

    Exclusive flush style aluminium windows that replicate traditional wooden casement style.

Traditional flush casements, redesigned.

Replicating traditional flush windows made from timber, the Flush Style aluminium system is like no other. Viewed externally, opening sashes sit level with the outer frame, providing a sightline that is naturally more appealing to the eye. Balance and proportion, with clean and crisp looks.


Designed for top or side hung opening-out windows, this is unique window system that is available exclusively from our factories. They are thermally efficient and virtually maintenance free – available in a range of finishes that perfectly complement our slim aluminium bifolding doors.

Flush aluminium windows


The flagship Flush Style aluminium window is designed to look like a traditional wooden casement window. With opening sashes sitting level with the outer frame, you get the look of a flush sash window except with the benefits of a modern aluminium system.


The sight lines are just 101mm from sash to sash – not only slim, but incredibly pleasing to the eye. They have authentic looks with balance and proportion. The clean, minimal flush style is complemented by concealed night ventilation and mullions & transoms that are concealed.

Built to last


Our affordable aluminium windows are highly resistant to corrosion and rust whilst offering strength and durability. Aluminium is extremely recyclable and very environmentally friendly – it’s lifespan is measured in decades instead of just years.


Aluminium windows also allow you to have your windows coloured in any of over 200 different RAL colours.  It is even possible to have your windows manufactured to have alternate colours on the inside and out.  All our products are painted in a polyester powder coat finish, which is renowned for not fading or flaking.


Powder coated colours



Windows can be powder coated in any of over 200+ RAL colours. In addition, most of those are available in matt or gloss finishes too! Dual colour finishes are also available, offering one colour outside with another colour inside.


If you are looking for an even more luxurious finish, additional premium colour ranges include metallic paints, textured surfaces, and their anodised effect finishes as well.


We have a choice of concealed night ventilation with an integrated head. This ensures that the stylish and slim look of your new Flush Aluminium Windows will not be disrupted by visible trickle vent canopy hoods.


The windows are fitted with multi-point steel locking mechanisms that exceed British Standards for security. Night Vents are lockable and key-locking handles are supplied with all opening lights.


Affordable Aluminium windows and doors are thermally efficient, contributing to a reduction in the cost of heating bills. Warmth and comfort are built in to our window systems.


Aluminium frames will never rot, rust, peel or flake, making them maintenance free. We offer our windows with a 10-year guarantee for your peace of mind – making them a sound investment.



This versatile range of profiles can provide many solutions for residential and light commercial applications. It can create traditional casement windows inspired by the elegance and styling of timber products, or contemporary style windows designed for modern homes or offices.
