Plastoform Acrylic Double-Glazed Windows

Plastoform (by Acryform, Slovenia) manufactures premium acrylic windows purpose-built for recreational vehicles. Their double-glazed construction uses shatter-resistant acrylic instead of glass — lighter, safer, and better insulating.

Key Features (All Plastoform Windows)

• Double-glazed acrylic — excellent thermal insulation, shatter-resistant, lighter than glass
• Tinted privacy glazing — reduces glare and provides daytime privacy
• Hidden hinge design — clean, modern look with no visible hardware on the exterior
• 4 opening positions — versatile ventilation from a small gap to fully open
• Locking handles — secure when closed or while driving
• Wall thickness: 24–40 mm (with optional extension elements for thicker walls)
• Suitable for flat or parabolic walls

Size Guide

Why Acrylic Over Glass?

• Weight: Acrylic is roughly half the weight of glass — critical in motorhomes where every kilogram affects fuel economy and payload
• Safety: Acrylic is shatter-resistant. If it does break, it breaks into large dull pieces rather than dangerous shards
• Insulation: Double-glazed acrylic provides better thermal insulation than single-glazed glass
• UV resistance: Tinted acrylic blocks UV rays, protecting interior furnishings from fading

Measuring for a Plastoform Window

1. Measure the wall opening (hole size) — width × height from inside the wall, at multiple points
2. Measure wall thickness — must be 24–40 mm. Thicker walls may need extension elements
3. Check wall profile — Plastoform suits both flat and parabolic (curved) wall surfaces
4. Note the corner radius — standard Plastoform uses R75 radius corners

Horrex DuoPliss Flyscreen & Blinds

Horrex is a Dutch manufacturer specialising in window treatments for recreational vehicles. Their DuoPliss (also called DuoPlissé) system combines an insect screen and a sun/blackout blind in a single compact unit.

How DuoPliss Works

The DuoPliss is a two-layer pleated system:

• Top layer: Fine mesh insect screen — keeps bugs out while allowing airflow
• Bottom layer: Fabric sun protection or blackout blind — blocks light and provides privacy
• A single smooth motion operates both layers — pull down for insect screen, continue for sun blind
• Silent operation — cords run behind the blind material, not through holes (eliminating noise)

Key Features

• Compact, space-saving design
• No visible screws — clean finish
• Beige/neutral frames that match most RV interiors
• Easy installation with supplied hardware
• Lightweight and durable
• European designed and manufactured

• Systems smaller than 900 mm use 4 wall screws, no Z-clips needed
• Check for wiring and electrical components in the wall before drilling

Milenco Universal External Blind

Size Matching — Windows + Blinds

If you're buying both a window and a blind, match them by size:

Already have a window? Just need a blind? The Horrex DuoPliss blinds work with most standard RV windows in matching sizes — not just Plastoform. Check your window opening dimensions and match to the closest Horrex size.

General Fitting & Installation Tips

Before You Order

1. Measure the window opening — not the old glass or frame. Width × height from inside the wall.
2. Measure wall thickness — Plastoform requires 24–40mm, Horrex requires minimum 26mm.
3. Check for obstructions — wiring, pipes, or structural members behind the wall at the mounting points.
4. Photograph existing windows from inside and outside — helpful if you need sizing advice.

Tools You'll Need

• Tape measure + spirit level
• Drill + drill bits (check wall material)
• Screwdriver (low torque setting for blind mounting)
• Flexible sealant (butyl or polyurethane — NOT silicone)
• Masking tape for marking

Common Mistakes to Avoid

• Measuring glass instead of opening — always measure the wall hole
• Ignoring wall thickness — if your wall is thinner than 26mm, blind screws may protrude outside
• Drilling without checking for wiring — use a cable detector or check from the other side first
• Over-tightening screws — acrylic frames can crack; stop when snug
• Using silicone sealant on windows — use butyl or polyurethane for long-term adhesion to acrylic and aluminium
