One of the most common questions we hear from clients looking for long-term marquee hire or temporary building space is: “Will it stay warm enough through winter?”

The answer: absolutely.

Today’s temporary structures — when properly specified — perform exceptionally well through every season. At Trafalgar, we design and install long-term marquees and temporary buildings that remain comfortable, energy-efficient and fully operational all year round, whether used as classrooms, canteens, welfare units, studios, storage, or additional workspace.

Energy-efficient insulation for long-term use

For long-term deployments, the right insulation is essential. It improves comfort, reduces heating costs and ensures your structure performs consistently over months or years.

We offer a range of insulation options specifically designed for long-term temporary buildings, including:

Insulated solid wall panels

These panels significantly reduce heat loss, increase structural rigidity and create a stable internal climate suitable for continuous daily use.

Specialised insulated linings

Lightweight yet extremely effective, these linings help regulate internal temperatures and improve the structure’s energy efficiency.

Double-skinned thermo-insulated roofs

Ideal for winter, these reduce heat escape and keep energy use low — an excellent choice for schools, business operations and long-term hospitality spaces.

During warmer periods, we can install full air-conditioning systems, ensuring year-round climate control for staff, students or customers.

Tailored heating systems for reliable year-round comfort

Every long-term installation operates under different site conditions. That’s why we offer site-specific heating solutions, designed to work within your existing power supply and operational requirements.

Our heating options include:

• Indirect, thermostatically controlled heaters – efficient, powerful and discreet — warm air is ducted into the structure without taking up internal space.
• Electric hot-water boiler systems – perfect for sites with electrical restrictions or where oil-based heating isn’t permitted.  We frequently install these systems for schools, colleges, and public-sector buildings requiring strict compliance.
• Outdoor heating for semi-open hospitality structures – for long-term restaurant, bar or café setups with open sides, we can supply the appropriate external heating to maintain comfort through colder months.

All systems can be serviced through scheduled ongoing checks as part of our long-term hire packages.

Heating solutions for specialist environments

Some temporary structures require more than “just heating”. They need controlled conditions suitable for activities such as:

• Education and classrooms
• Catering and dining facilities
• Storage, logistics & warehousing
• Dance, sports and training studios
• Film, TV & media production
• Construction welfare areas

One example is a performing arts school that required a fully insulated temporary studio. We installed:

• Hard walls and secure access doors
• Specialist flooring for movement
• Robust insulation
• A carefully balanced heating system

The space stayed warm and comfortable throughout winter, proving how well-designed long-term structures can perform under demanding conditions.

A comfortable, efficient space 365 days a year

Whether you need a structure for three months or several years, we make sure your temporary building remains:

• Warm in winter
• Cool in summer
• Energy-efficient
• Safe
• Fully compliant
• Comfortable for all users
