It is critical to inspect the delivery before signing the courier documents. If damage is visible, note it on the transport document and contact our customer support immediately with photos.

For cold climates, polycarbonate glazing is often a practical choice because it provides better thermal insulation and higher impact resistance than single-pane glass. The best option still depends on the greenhouse model, local wind and snow conditions, and whether you plan to heat the greenhouse.

Regular maintenance helps keep your greenhouse safe and long-lasting. Clean the glazing, check the frame, fasteners, seals and doors, and make sure vents operate freely. Remove leaves and debris from gutters or roof areas, and follow the manufacturer’s instructions for seasonal checks and snow management.

Greenhouse ventilation may include roof vents, side vents, doors, louvre vents and automatic vent openers. A well-planned combination improves air circulation and helps manage temperature and humidity during warmer periods.

Professional installation is not always required, but it can be a good option for larger, permanent or more complex greenhouses. Careful assembly, correct anchoring and a level base are essential regardless of who installs the greenhouse. Always follow the supplied installation instructions.

A stable, level and properly prepared base is important for the safe installation and long-term performance of most greenhouses. Suitable foundation options vary by model and site, and may include a concrete base, timber frame, foundation base or ground anchors. Check the product documentation before choosing a solution.

Some greenhouse models can be extended using compatible extension kits. Availability depends on the specific model, frame system and manufacturer. If future expansion is important, check this before purchasing and allow enough space when planning the installation area.

WOM exposure refers to standardized testing conducted in a "Weather-Ometer." This laboratory equipment simulates years of outdoor weather conditions in a short period by exposing the material to intense UV radiation, high heat, and moisture. This test ensures the plastic film or sheet meets durability standards and will maintain its structural integrity and light transmission over many years in a real-world environment.

Polycarbonate and acrylic are both strong, lightweight alternatives to glass, but they have different properties. Polycarbonate is known for its very high impact resistance and is often chosen for demanding applications. Acrylic (PMMA) offers excellent clarity and a smooth, glass-like appearance. The best material depends on the application, required strength, appearance and installation conditions.

Solid polycarbonate sheets are compact, transparent sheets with a smooth surface and a glass-like appearance. Multiwall polycarbonate sheets have internal channels that make them lighter and improve thermal insulation. Solid sheets are often selected for clear glazing and impact resistance, while multiwall sheets are commonly used for roofs, greenhouses and insulated structures.

Yes. Our polycarbonate and acrylic (PMMA) sheets include UV protection for outdoor use. This helps protect the material from weathering and supports long-term performance when the sheets are installed correctly.

The right thickness depends on the material, application, supporting frame, distance between supports, local wind and snow conditions, and the insulation or impact resistance required. For roofing and glazing projects, select the sheet thickness together with a suitable support and fixing system.

Yes. Polycarbonate and acrylic sheets can usually be cut to size using appropriate tools and a blade suitable for plastics. Measure carefully, support the sheet properly while cutting and follow the product-specific cutting guidance. Multiwall polycarbonate channels should be cleaned of cutting dust before the sheet ends are sealed.

Yes. Polycarbonate and acrylic sheets expand and contract when temperatures change. Always allow suitable expansion gaps during installation, use compatible profiles and fixings, and avoid overtightening screws. This helps prevent stress, distortion and damage over time.

Multiwall polycarbonate sheet channels should be protected from dust, insects and moisture with suitable sealing tape and end profiles. The upper edge is normally sealed with solid tape, while the lower edge commonly uses breathable tape to allow condensation to drain. Always install the channels in the correct direction and follow the instructions for the selected sheet system.

Use lukewarm water, mild soap and a soft cloth or sponge. Rinse the sheet thoroughly before wiping to remove dust and loose particles. Avoid abrasive pads, strong solvents and harsh cleaning products, as they can scratch or damage the surface.

Yes. Polycarbonate and acrylic sheets are widely used for outdoor glazing, roofing, shelters, greenhouses and similar projects. Choose the material, thickness, support spacing and installation system according to the intended application and local weather conditions.

Multiwall polycarbonate is a popular greenhouse material because its internal structure improves thermal insulation while keeping the sheets lightweight. Solid polycarbonate or acrylic may also be suitable where a clearer appearance is preferred. Consider insulation, light transmission, structural requirements and the greenhouse design when choosing.

Yes. Read the complete product-specific instructions before starting work and check that all components are present. Installation methods, required tools, fixing details and safety requirements may vary between products.

Many products can be installed by an experienced DIY customer when the supplied instructions are followed carefully. Larger, heavier or more complex structures may require more than one person. Professional installation can be a practical option where the project, site conditions or local requirements make it necessary.

The required tools depend on the product and installation surface. Common tools may include a tape measure, spirit level, drill, screwdriver, suitable drill bits, saw and personal safety equipment. Check the product instructions before starting and use only tools and fixings suitable for the materials involved.

A level, stable and properly prepared base is essential for correct alignment, secure fixing and long-term performance. An uneven or unstable surface can cause frames, doors, panels, profiles and seals to fit incorrectly and may place unnecessary stress on the structure.

Avoid installation during strong winds, heavy rain, snow or icy conditions. Large sheets, panels and lightweight components can be difficult to handle safely in poor weather. Choose calm and dry conditions, and do not start work unless the installation area can be made safe.

Use the supplied fixings whenever they are included with the product. If additional or replacement fixings are needed, they must be compatible with the product, installation surface and local weather conditions. Incorrect screws, unsuitable sealants or overtightened fixings can damage the material and affect the installation.

A reliable rule of thumb for roofing and plastic sheets is to double the total thickness of the materials being fastened. Calculation: (Sheet Thickness + Profile Thickness) x 2. For example, a 10mm sheet and a 20mm profile equal 30mm total; multiplying by two results in a recommended 60mm screw length for a secure connection.

Polycarbonate, acrylic and other plastic sheets expand and contract as temperatures change. The recommended expansion gaps, profiles and fixing method must be used to help prevent stress, buckling, cracking and leaks. Follow the product-specific installation instructions for the selected sheet system.

Our polycarbonate roof installation guide explains the main stages of the project, including planning the structure, preparing the sheets, fitting profiles, sealing sheet ends and finishing the roof. Use the guide together with the instructions supplied for your specific sheet and installation system.

Our greenhouse assembly instructions provide guidance for preparing the site, building a suitable base, assembling the frame, fitting glazing and securing the structure. Always follow the instructions supplied with your specific greenhouse model, as components and assembly steps may differ.

After installation, check that the structure is level, securely fixed and correctly aligned. Confirm that fasteners are secure without being overtightened, seals and end caps are fitted correctly, drainage paths are clear, and moving parts such as doors or vents operate freely.
