Aluprof – Aluminium Heritage

Suitable for every façade, Aluprof windows are engineered from strong aluminium to form a sturdy, minimalist frame.

Offering versatile designs, including slimline aluminium windows, the collection comes complete with a plethora of finishes, colours, and styles to suit your home or commercial space.

Suitable for modern and historic builds, these windows are not only sustainable but specially designed to blend seamlessly with contemporary architecture as well as traditional brick or stonework. State of the art renovation frames can also be fitted seamlessly around older windows, if they’re too fragile to be removed.

Designed with smooth opening and closing mechanisms, including side-hung, pivoting, and sliding, all Aluprof windows are practical and easy to operate. From statement floor-to-ceiling windows to chic cottage windows, our bespoke designs mean you are guaranteed a window to suit your requirements. Aesthetics and efficiency run hand-in-hand with Aluprof.

Specialising in large dimensions and invisible casements, the Aluprof aluminium window model maximises natural light, transforming your living and commercial interior.

While these windows are designed to bring the outside in, the frames are highly resistant to moisture and air infiltration, meaning you won’t have to worry about cold or damp weather conditions. Exceptional levels of thermal insulation keeps your home warm in the winter and your energy costs down. Added noise reduction is also a great way to keep the sounds of the busy, modern world out.

Very Happy

We’ve been very happy with the work Klosen recently completed for us. They installed a variety of windows and sliding doors for us on our new build project. All of the information we requested early on was provided promptly and they were great with our architect. Very happy with the end result and the colour they helped us chose.
