Roseview is one of the UK's foremost authority on timber-alternative sash windows. Since 1985 Roseview has specialised in manufacturing sash windows, making them the first company in the UK to do so. As a result they have more 35 years of dedicated knowledge and expertise, both in manufacturing sash windows and in general heritage and conservation window technology. Roseview manufacturers three models of sash window - Charisma Rose, Heritage Rose and Ultimate Rose - which combine to form the Rose Collection. Each model offers different features and benefits, and comes in at a different price point. From modern to heritage, new build to conservation, the Rose Collection has a model for every project. Roseview also manufactures Incarnation aluminium secondary glazing. Designed for refurbishment and conversion projects where replacement windows are not an option, secondary glazing brings modern levels of thermal and acoustic performance to original windows, without changing the appearance of the building.
