Frame Event Marquees for Extreme Cold Winter Outdoor Space

How to Operate a Winter Event Marquee Safely in –20℃?

An expert guide on using a winter event marquee in extreme cold. Learn about snow load engineering, thermal insulation systems, and industrial heating to keep your event marquee efficient at -20℃.

Q1: Is the structure of a winter event marquee safe during heavy snowstorms?

The Direct Answer: Safety depends on the Snow Load rating and the strength of the frame.

Standard tents cannot handle the weight of heavy snow, but a professional winter event marquee utilizes a high-strength 6061-T6 aluminum alloy frame. This material remains stable and does not become brittle in freezing temperatures. To prevent snow buildup, we design the roof with a steeper pitch to allow snow to slide off naturally and reinforce the beams based on local climate data. This ensures your event marquee remains structurally sound even during overnight blizzards.

Q2: How do you prevent rapid heat loss inside a winter event marquee?

The Direct Answer: By creating a Thermal Barrier using a multi-layer insulation system instead of a single-layer cover.

At -20℃, a single layer of PVC fabric cannot retain heat. To maintain a stable interior temperature, we recommend the following:

• Thermo Roof (Inflatable): This system pumps air between two layers of PVC, creating an air gap that acts like a “vacuum flask” to block heat from escaping through the top.

• Insulated Sandwich Panels: We replace soft side curtains with hard-pressed panels filled with rock wool or foam. These panels have a high insulation value, effectively keeping the cold out of the event marquee and maintaining a comfortable -20℃ interior.

Q3: How do you deal with condensation and air quality issues inside the marquee?

The Direct Answer: Use an Indirect Fired Heating System combined with active air circulation.

When the temperature difference between inside and outside reaches 40℃, moisture can condense on the inner walls of the event marquee, potentially damaging electronics. The professional solution is an industrial HVAC system that exhausts combustion fumes and moisture outside, sending only clean, dry, warm air inside. This prevents window fogging and ensures the air remains fresh for long-term working or living.

Q4: Will the freezing ground absorb all the interior heat?

The Direct Answer: Yes, which is why an Integrated Cassette Flooring System is essential.

Working directly on frozen ground or snow is inefficient and uncomfortable. Our event marquee flooring uses aluminum joists to raise the floor 10–20 cm above the ground. This “air gap” acts as natural insulation, cutting off the conduction of cold from the earth. When finished with carpet or wood, it provides a walking surface comparable to a permanent building.

Q5: Is it cost-effective to upgrade to these winter-ready configurations?

The Direct Answer: High-spec configurations lead to a higher ROI (Return on Investment) through lower energy costs.

While the initial setup for a winter event marquee is higher than a standard marquee, the insulated design can reduce fuel consumption by 40%–50%. Over several months of winter operation, the savings in heating costs are significant. More importantly, it ensures Business Continuity—preventing project shutdowns or staff discomfort, which is the core value for any B2B operation.

💡 Expert Tip

At -20℃, every detail matters. We recommend installing an Air-lock Entrance (a small foyer). This prevents a massive blast of cold air from entering the event marquee every time someone opens the door, maximizing your heating efficiency.
