Motorhome windows: Hinged window vs. framed window

Last updated: May 24, 2026

What are the differences between awning windows and framed windows in a motorhome?

awning window tilt outwards — similar to a tilt window in a house, only the sash swings outwards. They usually consist of a simple plastic frame with acrylic glass and a tilt fitting. Sash window on the other hand, are firmly installed in a stable frame, often with double glazing, and either do not open at all or open via a separate ventilation sash.

The most important differences at a glance:

Pro Tip: Awning windows are standard in many campervans and panel vans. Framed windows are more commonly found in fully equipped motorhomes and alcove vehicles.

What type of window is more affordable for an RV?

Outswing windows are significantly cheaper to purchase than framed windows. A simple outswing window (e.g. from Heki or Dometic) is available from around 100–150 € available, while comparable casement windows at Starting at €200 and quickly for high-quality models with double glazing. 500–600 € increase.

In the long term, however, framed windows can be more economical because they are more durable and need to be replaced less often. Anyone who uses a motorhome for many years should factor in the total costs over its lifespan – not just the purchase price.

Rule of thumb: Those who use a vehicle for occasional summer trips will find hinged windows more affordable. For those who travel year-round and rely on energy efficiency, framed windows pay for themselves faster.

Which type of window is better for thermal insulation and energy efficiency?

Casement windows are clearly superior when it comes to thermal insulation. Many models come with Double glazing (similar to household panes), which significantly reduces heat loss. This is particularly relevant for autumn and winter trips or for anyone traveling with auxiliary heating.

Awning windows usually have Single-pane acrylic glazing, which are barely insulated. At temperatures below 5 °C, they quickly fog up from the inside and let heat escape. For year-round travelers, this is a real disadvantage.

Those who pay particular attention to energy efficiencyshould also consider thermal curtains or custom-made insulating mats for hinged windows—this noticeably improves insulation without having to buy new windows right away.

How do I repair a broken RV awning window?

In many cases, a broken vent window can be repaired yourself if only the acrylic pane is cracked. The frame usually remains intact.

Step-by-step instructions:

1. Measure the disc: Note the length, width, and thickness of the original pane (usually 3–4 mm acrylic).
2. Order a replacement lens: Acrylic glass cut-to-size sheets are available online or at the hardware store. Pay attention to UV resistance.
3. Remove old adhesive and sealant: Carefully loosen with a plastic spatula, clean the frame.
4. Install new disc: Attach with special acrylic adhesive or caravan sealant.
5. Allow to cure. At least 24 hours before the vehicle is moved.

Important: If the frame itself is broken or warped, a complete replacement is recommended. A warped frame will never seal properly again — and moisture in the RV is an expensive problem.

Can I install casement windows myself, or do I need a professional?

Installing frame windows yourself is possible, but challenging. The cutout in the vehicle wall must fit exactly, the seal must be seated all around, and with vehicles with insulating cladding, it quickly turns into a project lasting several hours.

Self-installation: suitable if...

• Handcrafted experience is available
• The vehicle already has a suitable cutout.
• Good tools (jigsaw, sealant, rivet pliers) are available

Hire a professional: makes sense if…

• The vehicle does not have a cutout yet.
• The body is made of GRP or sandwich construction.
• Warranty on the tightness desired

A specialized company typically charges the following for installing a window frame: 150–400 € labor costs in addition to the window material. This is money well spent if you want to avoid water damage due to poor sealing.

What are typical mistakes when buying RV windows?

Many campers make avoidable mistakes when buying windows — and only notice it when the new window doesn't fit or leaks after the first trip.

The most common errors:

• Incorrect dimensions: Outer dimensions and installation dimensions (cutout) are not the same. Always check both dimensions.
• Incorrect window type for the installation depth: Some framed windows require a specific wall thickness—which can be a problem with thin van walls.
• Cheap seals: Inexpensive replacement seals from the hardware store rarely last longer than one season. Rely on caravan-specific EPDM seals.
• Acrylic instead of polycarbonate: Polycarbonate is more impact-resistant, but more expensive. For vehicles that are frequently driven on gravel roads, the extra expense is worthwhile.
• UV resistance not tested. Not every acrylic sheet can withstand years of sun exposure—yellowing and cracking are the result.

Wer ein Rent a campervan prefers to rent instead of buying, completely avoids these problems — the vehicles of professional rental companies are maintained and equipped with inspected windows.

What type of windows do professionals recommend for small vs. large RVs?

For small campervans and panel vans Professionals almost unanimously recommend awning windows: They are lighter, cheaper and can be opened in a space-saving manner without taking up much space outside. Especially for vehicles that are attached to the 3.5-tonne limit When operating, every kilogram counts.

For Large motorhomes, alcoves and semi-integrated models Framed windows are the better choice: They are a better fit for the robust construction method, offer more security, and improve the energy balance during long downtimes.

Decision rule:

• Vehicle under 3.5 t, summer travel, limited budget awning window
• Vehicle over 3.5 t, year-round travel, comfort important Sash window

Are awning windows or casement windows better for rainy regions?

Awning windows can leak in heavy rain, especially if the seals are old. Furthermore, they cannot be opened in the rain without water entering the vehicle — a real disadvantage on rainy days when you still want fresh air.

Who uses display windows anywayThe seals should be checked at least once per season and replaced if necessary. High-quality EPDM seals reliably keep moisture out.

Which type of window is lighter and saves more weight in a camper van?

Awning windows are lighter — a typical model weighs 2–4 kg, while comparable framed windows 4-8 kg bring to the scales. In a vehicle with four side windows, this makes a difference of up to 16 kg.

Yes, and professionals even actively recommend it. A proven combination: Pop-out windows on the sides for good ventilation and low weight, Framed window in the rear area or above the seating area for improved insulation and comfort.

This blend can be found in many serially manufactured motorhomes. It combines the strengths of both window types and minimizes their respective weaknesses. Anyone converting their vehicle themselves has complete freedom in planning.

What do I need to consider when replacing the seals on RV windows?

Replacing the seal is one of the most important maintenance tasks on a campervan window — and is postponed by many campers for too long. Leaky windows lead to moisture in the wall structure, which can cause expensive mold and structural damage.

What to Consider When Replacing Seals:

• Choosing the Right Seal: Always use EPDM seals for caravan applications. Hardware store foam doesn't last two seasons.
• Completely remove old gasket: Residue from adhesive or old sealant must be completely removed, otherwise the new seal will not seal properly.
• Clean the frame: Before installing the new seal, clean the frame with isopropyl alcohol.
• Check fit: Seals are available in various profiles — the profile must fit the frame, otherwise a gap will form.
• Use adhesive sparingly. Too much glue oozes out and not only looks unsightly, it can also impair the sealing function.
• Leak test: After replacing it, test with a garden hose to see if the window is sealed - better now than during the next downpour at the campsite.

Anyone who regularly checks their motorhome for defects is less likely to experience nasty surprises - similar to when... TÜV check, which becomes particularly critical from the sixth year onwards..
