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.

Foiled Finishes

Colour and finishes are an integral finishing touch for our Ultimate Rose windows. They will allow your customers to match our uPVC sliding sash windows perfectly to their home’s style and decor. We offer several wood effect options to provide a great replacement to timber windows. However, we also have the option for our Ultimate Rose windows to be finished in any RAL colour, or with a unique chalked finish that imitates painted timber.
