Prepare a Level Floor Surface

MOUNTING SURFACE:
The SunPorch sunroom/screenroom has been designed to mount on wood decks, concrete slabs, and patios. The heavy-duty aluminum framing is flexible, yet strong, and the glazing materials are rigid, shatter-resistant, and lightweight. The installed weight is less than 500 pounds for a 9' x 12' structure.
Most enclosed deck options have footings and concrete patios are generally poured on a base of well drained sand or gravel so they will not move in cold weather. Depending upon your climate and codes (if applicable), the base mounting surface preparation requirements may vary by region. Your local building inspector may or may not require modifications to your deck, slab or patio.
You also might be asked to provide details on the mounting surface to make sure it has been designed properly. This may require analysis services of a local engineer at your expense.
MOUNTING NOTES:
The SunPorch base must be mounted to a properly anchored surface to prevent movement. Because every installation has unique requirements, jobsite specific materials such as wood shims, lag bolts, anchors, etc., are not included with the kit. Your local home center or hardware store can provide you with these materials and is an excellent reference source for information on building and construction.
