No compromise on style or performance

Creating sash windows with modern performance and all the aesthetics of heritage style is what Roseview is about. Specify & Build reports on Roseview’s Rose Collection. 

Sash windows have always been an ideal option for classical and high-end architecture, and Roseview Windows has been manufacturing high end, heritage-style uPVC sash windows for more than 40 years. Its Rose Collection is a suite of three windows – Charisma, Heritage and Ultimate Rose – that have been designed to suit any style of building, from newbuilds to classic buildings. However, they don’t just focus on traditional style, they also deliver modern performance and compliance, to the benefit of architects, specifiers and homeowners alike. 

Energy efficiency and weather protection 

With windows making up, on average, 25% of the external surface area of a house, windows need to provide security, energy efficiency, weather proofing and – in some cases – good acoustics, as well as fitting a building’s aesthetic. All three of Roseview’s windows are A-rated as standard, with a standard U-value of 1.5W/m²K that’s upgradeable to 1.4W/m²K by changing the glass. Ultimate Rose and Heritage Rose offer an optional upgrade to ThermoVFlex technology, which reaches 1.2W/m²K. Energy efficient windows offer effective heat regulation all year round, ensuring the home stays warm in the winter and doesn’t overheat during the warmer months. Not only does this make homes more comfortable, it’s an eco-friendly choice that helps homeowners save on energy. 

Living in the UK means that the weather is often unpredictable, so windows that can face the challenges the climate throws at them is a must. All the windows in the Rose Collection are independently tested to BS6375 for air and water permeability and wind loading. All Rose Collection sash windows achieve Class 3 for air permeability, Class 8A for water tightness, and 1600 Pa (114.3mph) for wind loading, which is classed as hurricane level. To reduce draughts, each window has a system of six separate weather seals – a UV-resistant combination of QIon, brushpiles and EPDM gaskets – in the frame, around the recessed, stepped sashes and across the interlocks.  

Noise reduction as standard 

Comfort isn’t just about weatherproofing; it’s about providing a calm and quiet living environment.  With so many new and existing homes on or near main infrastructure, busy roads, urban developments and brownfield sites, noise ingress can be a significant problem. Where possible, noise insulation should be designed into projects without compromising other design elements. Rose Collection sash windows have been independently tested and accredited to provide noise reduction of up to 38dB. 

Security is a top priority for homeowners, which is why security is built into the heart of every Rose Collection sash window. The windows are internally reinforced with steel, increasing the strength and rigidity of the profiles. For enhanced security, the full suite of windows come with the optional addition of Secured by Design and PAS24:2022 accreditation, with Part Q compliance for newbuilds.  

Style without compromise 

Modern performance doesn’t mean having to compromise on the style and authenticity. Roseview’s 40 years of experience in sash windows has enabled Roseview to develop features that keep the traditional charm and character of period timber. Each window can be fully customised, from sash horns to woodgrain finishes, cills, internal staff beads, external chamber covers, astragal bars and window furniture, there is an array of traditional features for homeowners, specifiers and architects to choose from. Once the building is inhabited, there is no time-consuming maintenance or regular repainting required.  

The Rose Collection is listed on NBS Source, offering direct access to structured product data and documentation. Roseview also provides a full range of technical resources, including datasets, test reports and CAD drawings, making compliance simple.
