Sliding-sash windows
Why choose Roseview Windows
The primary advantage of choosing Roseview uPVC sliding sash windows is the perfect balance of traditional style and modern convenience. Unlike original wooden sash windows that are prone to rattling, draughts, and rot, the Rose Collection is manufactured from highly durable, maintenance-free uPVC. They will never require sanding or repainting; a simple wipe down is all that is needed to keep them looking pristine. Furthermore, the advanced multi-chambered profiles and high-quality double glazing provide exceptional acoustic insulation and A-rated energy efficiency. This ensures your home remains warm, quiet, and secure, while integrated tilt-and-slide functionality makes cleaning the exterior glass from inside your home effortless.
Three different styles for your budget
The Rose Collection Range
The Rose Collection features three distinct window systems to suit different budgets and architectural requirements. The Ultimate Rose is the pinnacle of the range; featuring true mechanical joints, an ultra-slim 35mm seamless midrail, and authentic run-through sash horns, it is frequently approved for use in strict conservation areas. The Heritage Rose offers an exceptional mid-tier option, utilising strong welded joints alongside traditional details like a deep bottom rail and a slim 44mm midrail for a classic timber look. Finally, the Charisma Rose provides a highly cost-effective, versatile solution that delivers modern performance while retaining the core aesthetic of a traditional sash window.

Frequently Asked Questions
Are Roseview uPVC sash windows suitable for conservation areas?
Yes. The flagship Ultimate Rose system was specifically engineered to mimic traditional joinery. Because it features true mechanical butt joints, a putty-line glass profile, authentic astragal bars, and the slimmest midrail on the market (35mm), it is frequently approved by local authorities for use in strict conservation areas.
How do I clean the outside of my new sliding sash windows?
All windows in the Rose Collection come equipped with a built-in tilt-and-slide function as standard. This mechanism allows both the top and bottom sashes to tilt inwards towards the room, meaning you can easily and safely clean the exterior glass from inside your home, even on upper floors.
What is the difference between mechanical joints and welded joints?
Mechanical joints (found on the Ultimate Rose) are constructed exactly like traditional timber windows, where the horizontal and vertical sections of the frame are physically butted together and sealed. Welded joints (found on the Heritage and Charisma Rose) use a modern manufacturing process where the uPVC is melted and fused together at high temperatures, creating a smooth diagonal seam at the corners that provides incredible strength.
Do these windows rattle in the wind like old timber sash windows?
No. Traditional timber sash windows often rely on weights and cords, which can loosen and rattle over time. Roseview windows utilise modern, pre-tensioned spring balances that hold the sashes firmly in place. When closed, the advanced weather-stripping and modern uPVC profile create a tight, draught-proof seal that eliminates rattling and reduces external noise.
Can I customise the colours and hardware to match my home?
Yes. The Rose Collection is available in a wide range of fade-resistant finishes, including traditional smooth white, highly authentic woodgrain foils, and bespoke RAL colour matches. You can also choose from a selection of traditional heritage hardware, such as globe hooks and tilt knobs, available in finishes like antique black, bronze, chrome, and gold.
