Under-deck door

[fignewton]

Not a very exciting project, but one I've put off for a while.  My under-deck is enclosed in lattice.  I had previously made a door out of PVC and lattice.  It had 3 stiles and lattice panels inset into grooves.  Over time, the lattice broke in places, but to replace it I'd have to disassemble the door.  This time, I wanted a design change that would let me remove any single panel for replacement easily.
    My design this time had 3 rails, dividing the door into 4 panels.  The door is 57 inches wide.  I used Azek and PVC panels, as I need to be able to pressure wash all the lattice a couple of times a year due to dirt and summer green mold growth.  I u used 1x6 for the rails and stiles.  These are held together with Azek glue and Kreg blue pocket screws.  This was stronger than my original design which just used pocked scews.  To make the "frames" to hold the panels flush with the back side of the door, I routed a 1/8 x 3/4 rabbet into PVC 1x2 moldings, then mitered them and screwed the frames in with stainless screws.  This way, the panels can move with expansion.  To add some vertical rigidity, I used two aluminum L channel pieces, one on each side.  The door is fairly lightweight, which is good given its width, and sits flush with the other lattice.[attachimg=1][attachimg=2]

The door looks good!

Is your deck waterproof? If so, how did you do that?

Not really waterproof.  The decking is composite.  My walkout door is straight ahead of the new lattice door, 15 feet back.  I have installed galvanized paneling as a ceiling of sorts under the deck about 20 feet wide to keep the rain off the underneath area on that side.  It’s installed with a slope to the outer edge of the deck, so water collected comes off the drip edge into a gutter system.  It’s nice to have it dry under that end of the deck.  I used to let my little doggie out under there when it snowed, and I can run my generator outdoors there when the power goes out.

How are the galvanized panels suspended under the joists? Or are they screwed to the joists? If so, do you get leakage?

Beautiful door!

The panels have edges that overlap and lock, so they don't leak.  They're screwed to the joists with the screws that have rubber washers for this type of roofing material.  I made tapered longer spacers the width of the joists out of pressure treated 2x4s, and nailed them to the bottom of the joists out near the end so that there would be a fall at the end of the panels  to promote water flow.  It's worked well and no leakage.
