At a Glance: Summer Cooling Tips
- The Enemy: Solar gain through glass windows is the primary reason motorhomes overheat.
- The Solution: Exterior shading is up to 80% more effective at stopping heat than internal blinds.
- The Material: Micro-perforated mesh panels block intense UV rays while maintaining ventilation and views.
- The Expert Setup: Combine front and side panels for maximum all-day protection.
When the summer sun hits UK and European campsites, stepping inside your touring vehicle can quickly feel like walking into an oven. Keeping a motorhome cool in summer requires stopping solar gain, the process where sunlight passes through your windows and traps intense heat inside the vehicle, before it warms up your living space. While many owners rely heavily on internal blinds or energy-intensive air conditioning units, the most efficient method is tackling the heat source from the outside. At Rose Awnings, we specialise in premium shading solutions designed to keep your living space comfortable and liveable without draining your leisure battery.
Why does your motorhome get so hot?
Think of your motorhome as a mini greenhouse on wheels. When intense sunlight streams through your large front windscreen and side windows, it strikes your dashboard, seats, and carpets. These surfaces absorb the light and convert it into pure heat. Because this heat cannot easily pass back out through the glass, it becomes trapped inside, causing the indoor temperature to skyrocket. Once your vehicle’s interior furnishings soak up this energy, they continue to radiate heat long into the evening, making a comfortable night’s sleep nearly impossible.
Why are internal blinds failing to keep you cool?
A common misconception is that pulling down internal flyscreens or silver blinds will successfully lower the temperature. While internal blinds stop the blinding glare, they are highly inefficient at thermal management. By the time the sun’s rays hit an internal blind, the heat has already passed through the glass and entered the cabin. The air trapped between the window and the blind quickly superheats, acting just like a domestic radiator inside your lounge. To truly stop the heat, you must intercept the sun externally.
How does exterior shading solve the problem?
To prevent solar gain effectively, external shading is vital. Investing in a high-quality Thule Sun Blocker system provides a smart barrier against intense UV rays. Unlike solid plastic sheets or canvas walls that trap stagnant hot air underneath your awning, these panels are manufactured using an innovative micro-perforated mesh fabric. This material reflects up to 85% of solar radiation, drastically lowering the temperature hitting your vehicle’s sidewalls. Because the fabric is translucent, it keeps your interior shaded without blocking your view or campsite breeze.
How should you configure your external awning panels?
For maximum protection throughout the day as the sun moves, a modular layout is best. Adding an external front panel slides directly into the lead rail of your awning, offering immediate relief from overhead midday rays. To combat lower angles from morning or afternoon sun, attaching a matching G2 side panel via a tension rafter creates a comprehensive cooling zone. Each Thule Sun Blocker features robust, weather-resistant materials designed for years of reliable touring.
Frequently Asked Questions
Can I leave sun blocker panels up in windy weather?
Because the micro-perforated mesh fabric allows air to pass through freely, these panels experience significantly less wind resistance than solid canvas walls. However, we always recommend securing them properly with quality pegs and tension straps, and winding the awning in if severe storms are forecast.
Do these panels provide daytime privacy?
Yes, the unique screen material offers excellent one-way visibility during the day. You can easily see out to watch the world go by, but anyone walking past your pitch will struggle to see inside, giving you peace of mind on busy campsites.
Will they fit my specific awning model?
These panels are specifically engineered to fit seamlessly with the Thule Omnistor awning range. If you are unsure about your awning model, projection, or mounting height, our team at Rose Awnings can assist you in selecting the exact size required for a flawless fit.
