Flush Style Windows

an Allstyle exclusive

We set out to create a window design which is seamless in appearance. Sleek sightlines and fluidity. Viewed externally the opening sash sits level with the outer frame in the closed position providing a sight line which is much more appealing to the eye than a traditionally made casement window.

Designed for top or side hung opening-out windows, this unique window is manufactured exclusively by Allstyle Aluminium and can be complemented with a wide selection of hardware to achieve the look you desire.


Allstyle aluminium windows are highly resistant to corrosion and rust whilst offering strength and durability.  An Allstyle aluminium window is maintenance free, built to last and above all, a premium product. Aluminium is extremely recyclable and very environmentally friendly – it’s lifespan is measured in decades instead of just years.


Aluminium windows are powder-coated, allowing you to have your windows finished in 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 have a polyester powder coat finish, renowned for its resistance to fading or flaking.



Strength & Durability are provided by the use of aluminium sections which give structurally sound windows for your peace of mind.


Warmth & Comfort are benefits enjoyed by homeowners because Affordable windows and doors are thermally efficient and contribute to a reduction in the cost of heating bills.


Elegant Slim Sightlines are features of the Affordable windows and doors, which are enhanced by an ovolo, chamfered or square profile edge appearance. Additionally, homeowners have a dual colour option which means having the choice of finishes and colours externally and internally.


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.


Alitherm profiles utilise Smart’s innovative polyamide thermal break technology which creates a barrier between the cold air outside and the warm air inside. This technology significantly reduces thermal transmittance and enhances the overall uValue of a product and is designed to meet the exacting requirements of Document L 2010.


Aluminium windows are all about slim, elegant sight lines to provide the look and feel you require. Combine this with the latest thermal technology and high-performance glazing then aluminium windows become the obvious choice to give any home that ‘architectural look’.

Using different sections it is possible to create traditional casement windows inspired by the elegance and styling of timber products, or contemporary style windows designed for modern homes or offices. Available with a choice of hardware and in a range of standard or non-standard colours, including metallic, dual colour & textured.
