To ensure proper installation, safety, and compliance with local regulations, please carefully review the following requirements before purchasing the Janssens Gigant greenhouse.
Structural Certification & Permits
We do not provide structural certifications for custom greenhouse configurations.
If structural certification or permitting documentation is required in your area, these must be obtained independently through a licensed local engineer prior to placing your order.
We can provide contact information for our engineering partner to assist your local engineer if needed. However, all final approvals and certifications must be completed locally.
Depending on your region, additional structural considerations such as wind load and snow load requirements may apply. These requirements can only be accurately determined by a qualified engineer familiar with local building codes.
Professional Installation Required
Due to the size, weight, and complexity of the Janssens Gigant greenhouse, professional contractor installation is required.
This is especially important for:
-
Handling and installing large, heavy roof glass panels
-
Ensuring proper leveling and alignment
-
Installation on a knee wall or elevated base structure
This product is not intended for DIY installation.
Wall Mounting & Foundation Considerations
Installing this greenhouse on or into a wall structure introduces additional structural challenges.
The heavy-duty portal frame system is designed to be securely integrated into the wall structure, which typically requires advanced planning and construction.
For this reason, it is strongly recommended to work with experienced professional masons or contractors when building or modifying any supporting wall.
Improper anchoring or wall construction may compromise the structural integrity and safety of the installation.
