What Roseview Windows does

Roseview Windows (legal entity Spicgem Limited) is a UK-based, privately held fabricator founded in 1977 in Olney, Buckinghamshire, and recognised as the UK's first dedicated uPVC sash window manufacturer since 1985. The company designs, manufactures and supplies the Rose Collection of timber-alternative uPVC vertical sliding sash windows (Ultimate Rose, Heritage Rose, Charisma Rose) alongside its wholly-owned Incarnation aluminium secondary glazing subsidiary and Foilit Northampton foiling operation. Core technology centres on mechanically jointed seamless run-through sash horns (Dolphin, Seahorse, Emperor), a proprietary 35mm midrail profile, and the ThermoVFlex system achieving an industry-first 1.2 u-value, with all products A-rated and Secured by Design / PAS 24 / Part Q compliant.

Roseview operates as a B2B trade fabricator, selling exclusively through a nationwide UK network of trade installers, fabricators, architects, specifiers, builders and commercial customers rather than directly to homeowners. Distribution is supported by the Trade Installation Partner Scheme (TIPS), a Trade Hub portal, dedicated installer training centre, and online quoting systems (BM Touch, Tommy Trinder Framepoint). Manufacturing spans 40,000+ square feet across multiple Olney units, employing 80+ staff under the Bygrave family leadership. Pricing is quote-based and tiered across the Rose Collection, with the company controlling a 40-year exclusive partnership with REHAU for profile supply.

Revenue is generated primarily through hardware sales of uPVC sash windows and aluminium secondary glazing to trade accounts, complemented by an expanding ecosystem of add-on modules (sash horns, foiled trims, trickle vents, online quoting). The business is family-controlled with no disclosed institutional investors, and is currently executing a five-year modernisation programme that has delivered the Foilit acquisition, TIPS launch, BM Touch portal and multiple product innovations during 2024-2025.

Allows Roseview to offer complete heritage window solutions including for listed buildings where uPVC replacement isn't appropriate.
• REHAUcoreTechnology or Integration · 1 January 198540-year partnership (1985-2025) with systems house REHAU.

Roseview was brought on as fabricator and within three years pivoted to become UK's first dedicated uPVC sash window manufacturer. REHAU continues to supply world-class profiles supporting Roseview's innovation.
• Peabody TrustfoundationalStrategic or Co-development Partner · 1 January 1985Long-standing housing association customer.

Expansion highlights6 records

Direct peers

• Quickslide: UK fabricator specializing in sliding sash windows and bi-fold doors, serving trade installers nationwide. Comparable to Roseview in trade-channel focus and heritage-style product offering.
• Zenith Staybrite Windows: UK fabricator of uPVC and aluminium windows and doors including sash window ranges, supplying trade installers. Overlaps with Roseview on sash window product category and trade-channel go-to-market.
• Victorian Sliders: Specialist UK manufacturer of uPVC vertical sliding sash windows serving trade and retail customers. Directly competes with Roseview in the timber-alternative sash window category with similar conservation/heritage positioning.
• Masterframe Windows: UK-based specialist manufacturer of timber-alternative uPVC sash windows serving the heritage and conservation market. Closely comparable to Roseview in product positioning, customer base (trade installers and conservation-area specifiers), and premium sash window focus.
• Evolution Windows: UK manufacturer of uPVC and timber sash windows and doors, including Storm 2 and timber-alternative ranges. Competes with Roseview in both trade supply and the heritage-style window segment.

Broad incumbents

• Everest: Long-established UK manufacturer and installer of windows, doors, and home improvements. A broad incumbent competing across multiple window categories including heritage-style products, though with a consumer-direct rather than trade-channel model.
• Eurocell: UK uPVC profile extruder and window/door fabricator that supplies profiles to Roseview (used for Charisma Rose) and also fabricates its own competing products. Comparable as both a supply chain partner and a competing fabricator in the broader uPVC window market.
• Anglian Home Improvements: One of the UK's largest home improvement companies manufacturing and installing windows, doors, and conservatories. A broad incumbent whose window portfolio (including sash-style options) overlaps with Roseview, though it serves end consumers directly rather than via trade.
• Safestyle UK: UK's largest uPVC window and door installer focused on volume retail consumer sales. A broad incumbent in the uPVC window category but competing primarily on price/affordability rather than the heritage/conservation premium niche Roseview targets.

Others

• REHAU: Global polymer systems house and Roseview's 40-year profile supply partner. Comparable as the upstream supplier underpinning Roseview's Ultimate Rose and Heritage Rose ranges, and adjacent as REHAU also sells window systems directly to other fabricators and competes in the broader fenestration market.
