Folding doors for coastal homes

Begin with the site

Give your architect, builder, and Lanai team the project address, opening dimensions, building plans, and an explanation of the exposure. An ocean-facing opening, sheltered courtyard, and elevated balcony may call for different design decisions.

Ask the project design professional to establish the required design pressures, impact requirements where applicable, and the documentation needed by the permitting authority. Do not select a system from a general wind-speed headline.

Ask for the approval that matches the order

Lanai offers impact-rated folding door and window systems. Product families, configurations, and approval documents must be matched to the intended installation; a family name or approval logo alone is not enough.

Treat the threshold as a design decision

Discuss weather exposure, finished-floor levels, the desired transition, overhangs, and drainage together. A low or flush appearance does not establish water performance.

The supplied 2019 E3 aluminum guide distinguishes standard, lowrise, and flush-guide arrangements. It calls for keeping standard-sill weep paths open and for drainage design by others with lowrise or flush arrangements. Use the current instructions and approved details for the system you actually order.

Plan for salt, sand, and service access

Ask for the care schedule and approved cleaning methods for the selected finish, glazing, seals, and hardware. Make routine cleaning and inspection possible without moving permanent furniture or finishes.

Include the owner or facilities team in the handover. Keep the order information, approved drawings, maintenance instructions, and warranty together so future service starts with the correct system details.
