How to Install a Caravan Window with Flyscreen

Intro
Modern caravan windows often include a built-in flyscreen and blockout blind. Installation is straightforward if you prepare properly and tighten the frame evenly.

Tools and Materials

Tape measure, drill/driver, screwdriver bits
Non-setting butyl tape or caravan window sealant
Masking tape, plastic trim tools, rags
Assistant to hold the outer frame during clamp-up

Before You Start

Confirm the cut-out size matches the window ordered.
Check wall thickness suits the frame clamp range.
Dry-fit the window to confirm alignment and screw reach.

Step-by-Step Installation

Prep the opening – remove old sealant, clean the surface, and ensure the cut-out is square.
Apply sealant – run butyl tape or a continuous bead of caravan-safe sealant around the opening, avoiding gaps.
Place the outer window – from outside, seat the frame squarely against the wall. Use masking tape to hold temporarily.
Fit the inner frame – from inside, align the inner clamping frame with the factory holes.
Insert screws – start all screws by hand. Tighten in a cross pattern a little at a time to compress the seal evenly.
Check operation – open and close the sash, run the blind and flyscreen, confirm latches lock positively.
Seal the perimeter – tool any external sealant neatly. Remove masking tape while sealant is still soft.

Common Mistakes to Avoid

Overtightening – can warp the frame and cause binding or leaks.
Gaps in sealant – always lay a continuous bead or full butyl loop.
Measuring the old frame – order by cut-out size, not overall frame size.
Ignoring wall thickness – ensure the clamp range matches your panel.

Aftercare and Checks

Recheck screw tension after the first drive as seals settle.
Keep slider tracks clean and lightly lubricated if applicable.
Inspect seals annually for compression set or damage.

Pro Tips

Use a second person to hold the outer frame for a cleaner finish.
Work in shade where possible so sealant skins slower and tools cleaner.
If between sizes, discuss trim options instead of enlarging the opening immediately.
