Ultimate Rose Sash uPVC Windows

Osborn Windows > Windows > Sash Window Installer > Ultimate Rose Sash uPVC Windows

The most authentic wooden window look for homes, new builds and other constructions. An award-winning window design which is specifically designed for the heritage and conservation sector, they are perfect for updating old frames, or for a fresh installation. The Ultimate is already accepted by a series of conservation areas across the UK. It was the winner of the 2013 New Product of the Year at the Glass and Glazing industry awards.

The Ultimate uPVC Alternative to Traditional Timber Frames

You will struggle to find a range of windows as effective at replicating traditional and heritage style windows; you will not be able to tell the difference. With features including:

  • Mechanical joints
  • Run-through horns
  • Woodgrain finishes
  • A deep bottom rail
  • Authentic putty lines as standard

These features all work together to effectively replicate the details of a traditional timber box sash windows.

In some cases, this style of window is the only uPVC window accepted in conservation areas, and it has been recognised in many of these locations. Worry less about getting planning permissions past local authority.

Top of the Range Security Features

Available with PAS24 and Secured by Design (SBD) accreditation this window is not just ready to match a conservation area’s demands, but it is prepared to stand up to intruders. Its security features are next to none. It’s inclusive of mechanical and magnetic locking features next to a series of different jambs and latches. Laminating the windowpanes is always an option to add further security to your frames. 

Ultimate Heat Retention

A weakness of aged timber sash windows is their heat efficiency. If they are particularly aged or have not been adequately maintained, they can lose heat through draughts and gaps in insulation. With double glazing as standard alongside the specially designed insulating airspaces found in our uPVC window frames, combined with their low conductivity, makes these windows extra resistant to heat transfer. 

No Nuisance Maintenance and Sustainability

With a tilting sash as standard, maintaining this window could not be easier. Giving the owner the ability to use a range of cleaning products, either off the shelf or homemade – keeping these windows pleasing on the eye and well-functioning could not be simpler.

57% of the molecular weight of PVC is derived from common salt, which is an abundant natural resource, with the remaining 43% derived from hydrocarbon feedstocks. PVC uses less fossil fuel to make than any other commodity plastic, can offer a lifespan of at least 35 years, and can be recycled as many as ten times.

Your Choice of Colours

uPVC double glazed windows are available in a wide range of colours and finishes, complementing the style of your property. We offer white windows as well as Rosewood, Cherrywood, Irish Oak, Black and White woodgrain finishes are also available.
