Flush Style Windows

Allstyle Aluminium

The Allstyle Flush Style Aluminium Window is seamless in appearance, with slim sightlines and a sleek, fluid design. Viewed externally, opening sashes sit level with the outer frame in the closed position and provide a sight line that the eyes find more appealing than a traditionally made casement window.


Manufactured exclusively by Allstyle Aluminium, this window features many unique features that include: concealed trickle ventilation and drainage caps, concealed mullions, and a dummy stay option. The system accommodates top or side-hung opening-out windows and each is complemented by hardware from a curated collection of handles and fixings to achieve exactly the look you desire.


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 Allstyle windows and doors, which can be enhanced by a range of single and dual colour options.


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 U value 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. Combining this with the latest thermal technology and high-performance glazing, 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 finishes.

Every aluminium window we fabricate is powder-coated with a polyester finish, renowned for resistance to fading or flaking, and 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.
