SJRV Caravan Window 400mm H × 450mm W – Blind & Flyscreen

Caravan Window – 400mm High × 450mm Wide

The SJRV 400mm H × 450mm W caravan window combines double-glazed acrylic, push-out ventilation, a blockout blind and an integrated flyscreen in a compact assembly.

Its slightly wider-than-tall shape provides daylight and fresh air where your caravan layout calls for a smaller window. The built-in blind and screen let you adjust privacy, light and airflow without fitting separate window coverings.

Measurements are Height × Width: 400mm high × 450mm wide. These identify the nominal window size, not the overall external frame dimensions.

Available with radius or square corner profiles, this window suits caravan renovations, replacement installations and new RV builds with a matching opening and wall construction.

Double-glazed, UV-resistant acrylic

The flat acrylic panel features double glazing to help reduce heat transfer through the window. UV-resistant acrylic is designed for outdoor exposure, while the flat exterior profile and black outer frame provide a clean finish.

Push-out ventilation with support struts

The panel opens outwards, with support struts holding the window open so you can adjust ventilation. Push-button locking handles secure the panel when closed.

Use the integrated flyscreen while the window is open to enjoy fresh air with an insect barrier. Close and lock the window before travelling.

Blockout blind and flyscreen included

The built-in blockout blind provides privacy and helps darken the caravan interior for sleeping. Its reflective backing helps reduce incoming radiant heat when drawn.

The blind and flyscreen can operate independently or clip together, allowing you to adjust their position as light, privacy and ventilation needs change.

Powder-coated aluminium frames

The window features a black powder-coated aluminium alloy outer frame and a white powder-coated aluminium alloy inner frame.

The inner assembly houses the blind and flyscreen for a neat interior finish. An EPDM rubber seal forms part of the outer frame’s sealing system.

Radius or square corner profiles

Match the window profile to your caravan’s wall opening:

• Radius corner profile: rounded R80 corners; suits wall thicknesses of 25–40mm.

• Square corner profile: square corners; suits wall thicknesses of 30–40mm.

For replacement installations, match the corner shape, opening dimensions and wall thickness. Refer to the drawing for your chosen profile before cutting a new opening.
