Polycarbonate greenhouses – durable, practical and easy to enjoy

A polycarbonate greenhouse is a practical choice if you want a durable growing space with good insulation and relatively little maintenance. The lightweight panels are more impact-resistant than traditional glass and are combined with strong frames to create a protected environment for vegetables, herbs, fruit and flowers.

For many gardeners, the appeal is simple: a greenhouse makes it possible to start growing earlier in spring, continue later into autumn and give heat-loving plants such as tomatoes, cucumbers and chillies more sheltered conditions than they would have in the open garden.

Why choose a polycarbonate greenhouse?

Polycarbonate combines several qualities that make it well suited to greenhouses.

The panels are lightweight, durable and resistant to impact, while twin-wall polycarbonate can also provide useful insulation. Many Dancover models use UV-protected panels together with rust-resistant aluminium frames, creating a greenhouse that requires relatively little maintenance.

Depending on the model, the panels may be clear for greater visibility or twin-wall panels that diffuse the sunlight more evenly.

A polycarbonate greenhouse is therefore particularly relevant if you prioritise durability, practical growing conditions and easy maintenance.

Polycarbonate or glass greenhouse – which should you choose?

Both materials can create an excellent growing environment, but they offer different advantages.

Choose a polycarbonate greenhouse if you want lightweight, impact-resistant panels, useful insulation and straightforward maintenance.

Choose a [glass greenhouse] if maximum transparency and the traditional greenhouse appearance are more important to you. Glass provides excellent natural light and clear views into and out of the greenhouse.

Neither material is automatically right for everyone. Your garden, budget, preferred appearance and what you plan to grow should all influence the decision.

Extend the growing season

One of the main reasons for having a greenhouse is the opportunity to create a more protected growing environment.

During spring, the enclosed structure warms more quickly than the open garden, making it possible to start seedlings and young plants earlier. Later in the year, the greenhouse can help protect crops as outdoor temperatures begin to fall.

This gives you more time to enjoy growing tomatoes, cucumbers, chillies, herbs, salads, flowers and many other plants.

A greenhouse does not automatically create ideal conditions all year round, however. Temperature, daylight, ventilation and possibly additional heating will determine what you can successfully grow during the colder months.

Choose the right size and design

Before choosing a greenhouse, think about both the space available in your garden and how you expect to use the interior.

A compact greenhouse may provide enough room for a few tomato plants, herbs and seed trays. A larger structure gives you more freedom for different crops as well as space for shelving, plant tables, irrigation equipment and comfortable walkways.

Greenhouses often fill up faster than expected, so it can be sensible to allow some extra room if your garden and budget permit.

Dancover offers polycarbonate greenhouses in different sizes, shapes and colours, from compact traditional designs to larger structures with generous doors and high ceilings.

If you want to combine growing with space for seating and relaxation, consider one of our [orangeries], which are designed specifically to accommodate both plants and outdoor living.

Where should you place your greenhouse?

A good location can make a significant difference to how well your greenhouse works.

Choose a level and stable surface with plenty of natural light and avoid unnecessary shade from buildings, trees and tall fences. A reasonably sheltered position can also reduce exposure to strong wind.

Think about everyday use as well. Easy access to water is useful, and you should have enough space around the greenhouse for assembly, maintenance and cleaning.

The ideal orientation depends on the layout of your garden and what you want to grow, so good overall light exposure is generally more important than following one fixed orientation rule.

Ventilation and good growing conditions

Warmth is useful for plants, but too much heat can quickly become a problem inside a greenhouse.

Ventilation windows and doors allow hot air to escape and help regulate temperature and humidity. Many polycarbonate greenhouse models therefore include one or more ventilation windows, with the number depending on the size and design.

Regular watering is equally important, especially during warm periods when plants can dry out quickly. Shelving, plant tables and irrigation systems can make the available space easier to organise and help simplify everyday greenhouse care.

The goal is not simply to make the greenhouse as warm as possible, but to create balanced conditions with sufficient light, ventilation and water.

What about winter and demanding weather?

Polycarbonate panels are robust, but not every polycarbonate greenhouse is designed for the same weather loads.

Wind resistance and snow-load capacity vary from one model to another, so always check the specifications for the greenhouse you are considering. Doors, windows and automatic openers should also be secured appropriately when the greenhouse is prepared for winter.

If you live in an area where significant snowfall or demanding winter weather is an important consideration, explore our [snow-proof greenhouses]. These models are designed with higher snow and wind load capacities than standard greenhouse structures.

Choosing the appropriate construction for your local conditions is more important than assuming that all polycarbonate greenhouses provide the same level of winter strength.

Frequently asked questions about polycarbonate greenhouses

Are polycarbonate greenhouses better than glass?

Not necessarily – they offer different advantages. Polycarbonate is lightweight, impact-resistant and can provide good insulation, while glass offers excellent transparency and the traditional greenhouse appearance. The best choice depends on your priorities.

Do polycarbonate greenhouses block UV rays?

Many Dancover polycarbonate greenhouse panels are UV-protected or UV-resistant. Exact panel properties vary by model, so check the specifications of the greenhouse you are considering.

Can you use a polycarbonate greenhouse all year?

The greenhouse structure can remain in place throughout the year when used according to its specifications, but what you can grow during winter depends on temperature, daylight, insulation and whether additional heating or lighting is used.

Are polycarbonate greenhouses easy to assemble?

Many models are designed for DIY assembly and include pre-cut panels, profiles and step-by-step instructions. Assembly varies according to size and design, and larger greenhouses will naturally require more time and handling. Always follow the instructions supplied with the individual model.
