Unbeatably authentic, the Ultimate Rose sash window is the pinnacle of sliding sash windows. The best aspects of modern uPVC materials and an indistinguishable timber aesthetic offer the greatest timber alternative sliding sash solution. Featuring our innovative and irreplicable 35mm midrail, it has a slim and sleek design that creates unparalleled style. Seamless run through horns and an internal interlock are just some of our handcrafted finishing touches that complete the look of these distinguished sliding sash windows
But the Ultimate Rose isn’t just the ultimate in terms of style; it will also provide your homeowners with fantastic performance. A rated for its thermal efficiency, it’ll keep homes warm throughout the year, potentially also saving customers on heating costs. While the heat stays inside, noise will be kept out, with our Ultimate Rose windows providing sound reduction, keeping your customer’s interior peaceful and quiet
Ultra Slim Meeting Rail
Our Ultimate Rose windows use a 35mm meeting rail, the slimmest meeting rail available. Significantly thinner than most meeting rails, it ensures the authentic timber replication of our sliding sash windows. This incredibly slim design feature makes the meeting rail look like a single solid piece of timber, keeping the wooden aesthetic. It’s a small but essential design feature that reflects the attention to detail Roseview take towards our sash windows
Authentic Mechanical Joints
Pushing the boundaries of timber replication, we have developed true end-sealed mechanical joints that capture the look of traditional sliding sash windows. We ensure that every join of our uPVC sliding sash windows is finished in a butt joint, a distinct timber stylistic feature. These joints are also constructed in the same fashion as timber – horizontal on the frame and vertical on the sashes. Homeowners get authentic style with an modern performance
Run Through Horns
One of our most innovative design choices was our decision to use seamless run through horns on our uPVC sliding sash windows. This recreates the style commonly found on Edwardian and Victorian timber windows and is a great finishing touch for homeowners looking for perfect timber style. What sets these apart from other sash windows is that the horns have no visible cap, seam or shadow line. However, to give you and your homeowners an extra level of choice, we include the option to forgo the run through horns, making the Ultimate Rose sash window perfect for matching the Georgian style
Seahorse Sash Horn
As an upgrade option, we offer a classic curved horn, which is typical of traditional hardwood sash windows from the 19th century. Although these sash horns were purely decorative, they were often used by joiners to demonstrate superior craftsmanship.
Chamber Cover
A new decorative feature exclusively available to Ultimate Rose, the chamber cover is an innovative new system that provides a seamless finish to the external window while providing a traditional appearance that you can’t get on any other uPVC sash window. The chamber cover comes as an optional extra which can be colour matched and finished for any project.
Authentic Joints
Constructed using traditional methods you’d find in a joinery-built timber window, the Ultimate Rose sash window can achieve what no other can. They have true end-sealed mechanical joints for perfect period authenticity.
Eclipse Trickle Vent
Our newest optional feature, Eclipse, is a two-part hood system that replaces the external trickle vent hood with a foil-matched aluminium cover and separate flyscreen, both of which run the full width of the window. Eclipse attaches directly to the top of the window frame without adding any height

Astragal Bar options
A key feature of our uPVC sliding sash windows, astragal bars are an essential part of traditional design. They are an identifying characteristic of Victorian, Edwardian and Georgian timber sash windows.
We have excellent flexibility and versatility when it comes to astragal bar design for our sliding sash windows, ensuring replication of any period style
Our Ultimate Rose and Heritage Rose windows use authentic, fully putty line chamfered bars on the outside, with ovolo inside the frame. Our Charisma Rose sash windows use cottage style ovolo bars inside and out.
Our astragal barred sash windows use back to back duplex bars inside the glass unit to replicate the style of sperate glass panes. Colour matched to your customers colour option; these will fit with any traditional property.
These bars are manufactured using full length aluminium carrier bars instead of the classic clips and tape approach. This makes our astragal bars stronger and more durable than those you’d get elsewhere.
Some of the most popular astragal bar designs are shown
Victorian
1837 – 1901. Single vertical astragal bars, reflecting the improved glass technology that allowed for larger panes
Georgian
1714 – 1830. Grid pattern, necessitated by glass technology only allowing for small panes
Edwardian
1901-1914. Purely decorative, leading to a mixture of Victorian and Georgian revival style
Perimeter Bars
Modern style enabled by improved flat glass technology. Often used to show off wealth by people who could afford the new, larger panes
Bespoke
Used throughout history to add design flair to windows. Includes anything from perimeter bars to dual verticals and fully bespoke grids with stained glass elements. Often found in clusters in a given area
Sills
We use integrated flush cills as standard in our Rose collection sash windows, which fit perfectly on top of stone cills. However, we also have a selection of projecting cill options to ensure we fulfil your customers’ requirements
