Our dedication to producing authentic sash windows has allowed us to become the industry leader for uPVC sash window manufacturing. To ensure that installation is as high quality as the sash windows themselves, we handpick reputable, professional installation companies as Rose Collection Approved Installers. Although independent companies, we have worked with these approved installers for years; we know and trust their work, ensuring they will deliver an installation that meets all requirements. This ensures hassle free, complete installations with complete peace of mind, Uf your project requires other glazed products that we don’t manufacture (e.g. doors), our Approved Installers will be able to help with those too.
