How to Install a Prefabricated Aluminum Sunroom Kit

• 1

  Prepare foundation. Options include a 6-inch height poured-in-place concrete pad, finished wood deck, level patio or kneewall made from wood, brick, concrete pavers or stone.

• 2

  Lay out bottom rails in the exact place you want to install the sunroom and attach to wood deck, concrete pad or kneewall with lagbolts or masonry screws, ensuring all angles are at 90 degrees.

• 3

  Where the two bottom rails abut the house, attach a vertical rail to the house with lagbolts, ensuring that they are securely fastened to an interior stud, concrete block or brick wall. For additional support, you can attach a 2x6 to the wall first.

• 4

  Attach the ledger on top of the two vertical rails with lagbolts.

• 5

  Assemble vertical and horizontal rails into an L-shape on the ground, then lift and secure into place. Continue like this until all aluminum rails are installed.

• 6

  Attach glazing and door with the included assembly pieces.
