AluK Optio 58BW Casement

An understated elegance

We’ve also offer AluK’s Flush variant of the 58BW ST to our range. In common with the Optio 58 BW ST, the AluK optio 58bw casement aluminium window has an ultra-slim 46mm sash, which combined with a flush finish, has been developed to create a clean and contemporary appearance.

Suitable for either casement or French casement installations and top and side-hung options, the AlUK 58BW Flush Casement can also be combined with different colour options to create a more subtle and understated finish.

Like the rest of our window and door range, it features multi-point locking and cutting edge thermal breaking technologies.

Durable colour

Our aluminium window and door ranges use a special flash-anodising process.

Completed ahead of powder coating this creates a protective anodised layer of aluminium oxide providing a better substrate for powder coating but also preventing filiform corrosion.

It means that our window and door range is supplied in a marine grade finish as standard and guaranteed for 10-years.

Standard Colour Options

Our standard colour ranges include a choice of white, anthracite grey, chocolate brown and deep black, plus dual colour anthracite grey-on-white and deep black-on-white.

Special Colour Options

We can also offer you access to a range of textured finish options and supply any RAL colour on special order, giving your customers the flexibility to pick out the perfect shade to compliment their property.
