THE ULTIMATE ROSE BY ROSEVIEW
The most authentic timber-alternative sash window in the UK.
When you want a sash window that genuinely passes for timber — not just a passing impression — this is the one. Every joint, every horn, every detail is engineered to replicate traditional joinery, without any of the rot, the rattle, or the upkeep.
TRUSTED PARTNERS & ACCREDITATIONS
MADE FOR THESE HOMES
Right at home, whatever you're working with.
The Ultimate Rose isn't just for one type of property. The detailing flexes to suit period restorations, conservation areas, and modern builds wanting a bit of character.
Traditional Homes
Authenticity matters when you're restoring a period property. The fine details — the joints, the horns, the bar profiles — are what separate a proper sash window from a passing imitation.

Modern New Builds
If you're building or renovating and want to add some character, sash windows give a modern home an entirely different feel — timeless rather than off-the-shelf.
Conservation Properties
Sash windows are a defining feature of British architecture. The Ultimate Rose has been engineered with conservation requirements in mind — heritage authenticity at its core.
AUTHENTIC DETAILING
Nine details that make all the difference.
This is where Ultimate Rose stands apart from every other uPVC sash on the market. Look closely at the joints and the horns — most sashes give themselves away. These don't.
Authentic Joints
Mechanical 90° joints on frame and sash — exactly as found on traditional timber windows. No tell-tale welded mitres.
Authentic Astragal Bars
Properly proportioned Georgian and Victorian bar configurations — not the chunky stuck-on bars you see on cheaper sashes.
Removable Staff Bead
Just like a timber sash, the staff bead can be removed for servicing. Practical and authentic in equal measure.
Eclipse Trickle Vent
Concealed ventilation that meets Building Regs without ruining the look — none of that ugly plastic louvre on the head of the frame.
Chamber Covers
Concealed drainage and chamber covers — a clean look from every angle, top, bottom and side.
Globe Furniture
Traditional cast-style furniture — sash lifts, cam locks and pole eyes that suit the period of the property.
Seamless Midrail
The mid-rail where the sashes meet looks like a single piece — no awkward join lines giving the game away from inside or out.
Deep Cill
A substantial deep cill that matches what was there before — the right proportions for period properties where shallow cills look wrong.
Three Finish Options
Choose between Chalk, Woodgrain or Smooth — match the original timber finish or pick something contemporary.
HORN OPTIONS
Energy Efficient
A-Rated as standard, with a U-Value of 1.5, which can be up upgraded to 1.2.
