Case study

Since its inception Wooden Windows has produced high quality timber windows. With high attention to detail, using the best products and machinery available, our windows comfortably fit into high end properties, where high standards and expectations are required.

The Wooden Windows branding compared to our product was weak, and it is important within our strategy for growth to reach the world with branding that suits the product we’ve been producing for years.

Introducing BOISROIS. BOISROIS redefines our business, a new brand, that not only strengthens our existing strategy, but enables us to extend into new markets outside of the UK with our new generation of tilt and turn window in a ClimaTrend style.

With our ambitious nature, we are investing heavily not only in the brand and marketing, but also into upgrading our factory, with new machinery and standards being raised further to ensure quality, thermal insulation, design and capacity.

In the coming months, we are working on developing our new online presence, with a brand new website, social media outlets and print media.
For updates, please ensure keep an eye on our current social media outlets or by joining our mailing list.

BOISROIS – The wooden window manufacturer you can trust to exceed your expectations.
