A greenhouse is one of the most popular garden structures in Lithuania. Many of us can't imagine a summer dinner table without fresh, clean, flavourful vegetables grown in our own greenhouse: lettuce, tomatoes, peppers, cucumbers or zucchini. As our lifestyles and hobbies change rapidly, so does the function of the greenhouse. A greenhouse can be used not only for farming. It can also serve as an additional leisure space where it is a pleasure to spend time at any weather. A quality and functional greenhouse will become the highlight of your garden or yard.

When choosing a new greenhouse, think about:

• Why do you need a greenhouse? What will you do in the greenhouse?
• Who will use the greenhouse, how and when?
• What materials should the greenhouse be made of?
• What shape and size do you want?
• Where will you put the greenhouse? How much space will you give it? Is the surface of the site is leveled?
• How much money can you spend on the greenhouse?

GARDENIS greenhouses are manufactured using 4mm tempered clear glass and 10mm clear polycarbonate.

We are often asked, which greenhouse material you recommend—glass or polycarbonate?

There is no clear answer. Each of us has different requirements regarding form, function, and aesthetics, which may or may not be met by both materials. When choosing a material for your greenhouse, you need to consider the main features of both.

Glass greenhouse:

• Aesthetic appearance
• Extremely durable
• Maximum transmission of sunlight
• Resistant to scratches, heat, and cold, easy to clean and wash.
• It warms up quickly but cools down quickly.
• Higher weight, more complex greenhouse roof construction

Polycarbonate greenhouse:

• Excellent thermal insulation properties
• Proper sealing of polycarbonate channels is crucial
• Long-lasting but more susceptible to scratches
• Lower weight, simpler greenhouse roof construction

The greenhouse must be set back at least 1 m from the boundary of the adjacent plot.

Choose a safe, sunny, and wind-free garden location for the greenhouse.

Do not place the greenhouse under trees or close to another building. This will avoid shade, which reduces the amount of light the plants need.

In addition, falling fruit, branches, or snow can damage the glazing.

Also, nearby trees' roots will drain your greenhouse's soil much faster.

GARDENIS greenhouses, conservatories, garden rooms, and other outdoor structures are crafted from premium-quality raw materials sourced directly from leading manufacturers within the EU.

• The structures are built using aluminium profiles of various shapes, lengths, and thicknesses, securely assembled with stainless steel bolts and nuts for maximum durability.
• We use 4 mm tempered safety glass and/or 10 mm clear twin-wall polycarbonate for coverings, which offer excellent insulation and protection.
• All coverings are secured with EPDM rubber seals, which are highly resistant to weathering, chemicals, and extreme temperature fluctuations, ensuring long-lasting performance.

• All GARDENIS products are designed with the customer/end user in mind. They adhere to the D.I.Y. (Do It Yourself) principle, allowing you to assemble any greenhouse model independently.
• Each product package includes detailed assembly instructions in multiple languages and a complete list of the product's elements.
• A solid, stable, and even foundation is essential for any greenhouse. All GARDENIS greenhouse models include an aluminium base as a reliable foundation. Our greenhouses can be installed directly on the ground, grass, terrace floors, paving stones, or concrete surfaces. While concrete or brick wall-type foundations are not required, they can be used for additional stability or style preferences.
• Before selecting the design and size of your greenhouse, it is essential to check your local legal requirements for greenhouse installation. This step ensures compliance with local regulations and a smooth installation and usage process.

Packaging

Our products are large aluminium structures with glass or polycarbonate. All elements are carefully packed to ensure safe transport and practical handling at every stage - from loading to installation.

Aluminium components are packed in carton units of up to 30 kg, suitable for handling by two persons.

Polycarbonate sheets are packed in carton and can typically be handled by one or two persons.

Glass sheets and panels are always packed in a wooden crate. These are heavy and require technical equipment (such as a forklift or crane) for loading and unloading.

-

Glass sheets for greenhouses are packed in 1 (for larger structures - 2, 3) wooden crates.

-

Structural (aluminium) profiles are packed in carton boxes.

 -

The box length corresponds to the longest wall of the greenhouse (up to max 604 cm); width 45 cm, height 20 cm.

The number and lengths of carton boxes vary according to the dimensions of the greenhouse structure.

Max. weight per carton box: 30 kg.

As each our product varies in size, weight, and packaging, therefore it requires individual loading arrangements. Detailed cargo information is provided upon order submission.
