OW70 · OW80

The classic British window, re-engineered in aluminium. Casements open outwards for maximum ventilation, with slim frames that let in more glass than a standard UPVC window of the same opening.

Security: Multi-point locking, PAS 24 accredited
Glazing: Double or triple glazed

Slim sightlines for maximum light
Egress and fire-escape options
Matched to your door finish

OW80 Premium

Bay Windows

A bay adds floor space, light and presence to a room. The OW80 system allows bays to be constructed with an internal flush design, giving a clean, contemporary finish inside as well as out.

System: OW80 Premium
Design: Internal flush finish
Options: Angled or square bays

Adds usable floor area
Roof and underside finished to match
Insulated bay roofs available

Glazing: Fixed, or with opening lights
Finish: Any RAL shade

Precise site-measured templates
Fixed and opening combinations
Ideal for vaulted interiors

Security: Multi-point locking

Direct access to gardens and balconies
Matched to French doors

Hardware: Matching handle suite

Creates an inside-outside servery
Flush stacking panels
Colour matched to your doors

Exceptional thermal performance

The Systems

OW70 Slimline, or OW80 Premium.

Two aluminium window systems, one bespoke process. Both are engineered, powder coated and assembled by Origin in the UK, made to your exact sizes and covered by a guarantee of up to 20 years. The difference is how much frame you want around the glass — and how far you want the thermal performance pushed.

OW70

OW70 Slimline

A refined aluminium casement window with elegant proportions. Its 65mm sightline creates a slim, considered frame that works just as well on a contemporary extension as it does on a period cottage.

Sightline: 65mm
U-Value: Up to 1.2 W/m²K
Configurations: Fixed, side-hung and top-hung
Best for: Slim frames and maximum glass

OW80

OW80 Premium

Built for homes where thermal performance comes first. U-values as low as 0.8 W/m²K, a more substantial 91mm frame and two sightline options — presence and comfort in one window.

Sightline: 91mm
U-Value: Up to 0.8 W/m²K with Aerogel
Configurations: Fixed, side-hung and top-hung
Best for: Thermal performance and larger openings

Both systems are available in the Soho range, in over 150 RAL colours — including dual colour inside and out — with a standard guarantee of up to 20 years, or 10 years on the frame and 5 on hardware in marine environments.

Origin square sash aluminium window in the Soho style

The Square Sash

Square sash windows, exactly square.

A square sash window is a casement window with a single, square-proportioned sash — one clean light of glass, symmetrical from every angle. It's the detail that keeps a full-house scheme consistent, and it's made bespoke to your opening in either Origin system.

Specify it as a fixed picture window, or as an opening sash side-hung or top-hung for ventilation. Square sash windows are a natural fit for the Soho aesthetic with steel-style bars, and for Georgian-style homes where square proportions and flush casements are the whole point — often sitting alongside Origin doors in the same finish and hardware.

Systems: OW70 Slimline & OW80 Premium
Arrangement: Fixed picture, side-hung or top-hung
Aesthetics: Soho steel-style, Gallery or Georgian
Finishes: 150+ RAL colours, dual colour available

The Soho Range

The Soho window, and the Soho range.

Soho is the steel-look range for Origin windows — slim aluminium frames with steel-style square bars, giving the industrial character of steel without the maintenance. It runs across casement, square sash, picture and tilt & turn windows, so a whole house can be matched in one finish.

Soho

The Soho Range

Steel-style windows, slim and architectural.

Clean, uninterrupted lines and a flush, minimal finish. Soho is the range that includes the Soho window — steel-style square bars in slim aluminium frames, giving the industrial look of steel without the maintenance. It suits modern extensions, new builds and interiors where the glazing should recede and the view should lead.

Sightlines: 65mm on OW70 · 91mm on OW80
Glazing bars: Steel-style square bars
Best for: Contemporary extensions and period renovations
Hardware: Signature Knurled or slim lever

Window Hardware

A handle for every window — and every style.

Inline, offset and heritage handles for the casement windows, plus the Rounded and Gallery handles made specifically for Tilt & Turn. Every handle can be finished to suit your frame, whether that's a sleek Gallery style, a bold Soho statement or a traditional Georgian look.

Tilt & Turn handles

Tilt & Turn windows need a handle built for two motions: rotate it 90° and the sash tilts gently from the top; rotate it 180° and the sash opens fully inwards. These two handles are designed for that movement — and available on tilt & turn windows only.
