Caravan Windows: All You Need to Know

Caravan windows: all you need to know

Owning a caravan opens the door to endless adventures on the road, but your caravan occasionally requires a little TLC. Caravan windows are easily overlooked, as these clear plastic units, rubber seals, and various catches appear primarily maintenance-free.

These double-glazed window units provide us with a view of the stunning landscapes we encounter and insulate us from inclement weather. However, simple maintenance could extend the life of our caravan windows, saving us from costly repairs in the future.

What are caravan windows made of?

Caravan windows are typically made of durable, lightweight materials like acrylic or polycarbonate. These materials are preferred because they resist cracking and shattering, making them safer and lighter options for leisure vehicle use. Additionally, they are often treated with UV protection to prevent discolouration and damage from sunlight exposure. Caravan windows are designed to provide a clear view of the outside while insulating the interior living space from adverse weather conditions.

Types of caravan windows

A simple overview of the many different types of caravan windows and some key information for each one.

Traditional Windows

Much like house windows, traditional caravan windows were made from glass, with many pre-war examples having leaded windows. However, advances in transparent plastics transformed the way we caravanned.

Acrylic windows

Acrylic windows are popular due to their lightweight and durable nature. These windows are easy to handle and resistant to shattering, making them a practical choice. It remains a popular material, with Polyplastic supplying many acrylic caravan windows to UK manufacturers.

Polycarbonate windows

Polycarbonate is made from synthetic resin. It is easily shaped and moulded and is well known for its durability and impact resistance. It is also lightweight, making it the perfect partner for a modern window system.

Double glazing windows

Double glazing tends to be used with plastic windows, as it's easy to construct a thermally efficient unit from acrylic or polycarbonate.

Caravan window seals

An annual damp test is an essential part of the servicing schedule to ensure your caravan remains watertight. Although maintenance-free, window seals sometimes fail, leading to water ingress around the window areas.

A visual inspection usually alerts caravanners to a potential seal failure. This can be done by lifting the window and checking that the exterior edge of the seal remains bonded to the caravan's exterior skin. If all looks good, applying a thin film of silicon spray to the seal's rubber lip aids its water-repelling ability. Implementing the correct window maintenance regime can add years to the lifespan of window-related products.

Caravan window blinds

Caravans are usually fitted with two blinds. The first - the flyscreen - keeps insects at bay, while the second acts as a blackout blind. Two nuggets of caravan blind information are worth sharing:

Key guide for caravan blinds

1 - What if the light streams through?

If light streams through the bottom of the blackout blind, close the flyscreen before closing the blackout blind. The flyscreen frame bridges the gap between the blackout blind frame and the wall.

2 - Why you should not to leave blinds down for extended periods?

Don't leave the blinds down for extended periods. While it is tempting to leave them closed while in storage, this can weaken the springs over time.

Caravan window locks

Many caravans have basic window catches that turn ninety degrees to open and close.

Some models have a pushbutton operation that acts as an additional layer of security, making it difficult for the catches to be pushed upwards from underneath.

Security devices are available to buy, stopping anyone from opening the window from outside.

Repairing a caravan window: How to remove scratches

Removing scratches from a plastic caravan window may seem daunting, but a renovation kit for plastic headlights will likely contain everything you need to remove lighter scratches.

Halfords sells an Autoglym kit for £29.99.

A guide on how to remove scratches

1. Sand the scratch with the abrasive disc.

2. Remove sanding marks and any remaining fine scratches with the foam disc.

3. Finish with the finest-grade foam disc.

4. Attach the polishing head to a drill.

5. Apply the polishing compound to the polishing head.

6. Polish the window until any haziness has gone.

7. Clean and buff with the microfibre cloth.

Replacing a caravan window

Should you need to remove a caravan window for repair or replacement, the following steps make it an easy DIY task:

On the inside of the window, unscrew the fixings that hold the catches and stays to the window.
Outside, lift the window to expose the end cap screw and remove it.
With the screw removed, the window assembly can be slid along the hinge.
Slide the window along this hinge until the window is free.
Place it somewhere safe and scratch-free to protect the window.

To install a window, follow the above steps in reverse order.

Cleaning and maintaining your caravan windows

Regularly cleaning your caravan windows will prevent the build-up of dirt and grime.

A simple exterior shampoo and a soft sponge will work wonders, but avoid abrasive materials that could leave minor scratches on the surface.

Road grime can also be abrasive, so take care.

Inspecting the window seals is a worthwhile task.

Lift the window and check that the outside of the seal is firmly bonded to the caravan's exterior skin. Don't forget the moving parts.

Hinges and locks need lubrication to ensure smooth operation and to prevent corrosion.

A little attention here can save you from sticking windows and doors. Silicon spray works wonders.

Frequently Asked Questions
