Acrylic or polycarbonate skylight dome sizes came today. The "can in height. Its width and length anywhere from 12" traditional, however, are square to rectangular, and run from 5 to 36 "and 1 / 8" thick.
These domes can be mounted on wooden rods (2x2 "to 2x6") for the roof tiles or thin metal caulking to prevent rain, lightning every loss. These domes can also be surface mounted directly on the tar paper and woodMovies directly under the tiles.
In the latter case, the coupling flanges are secured directly surrounding shingles on her at full throttle, as the shingles is often over the metal roof windows, the chimney of the furnace, duct openings, etc. down. This setup minimizes the height of the dome.
Problem. They are in both cases, no matter how or domes mounted, it can and will deliver similar condensation reactions and losses, even if they have a plastic innerSign in them. These domes are also prone to dropping large hail, tree branches, earthquakes, roofing negligent or cracked. When these events occur, skylights and loss of rain water, in addition to the formation of moisture.
Solution. Create and install a plate-type box 5-1/2 "tall clear cover hard over the dome on the roof. This cover is like a window of time is changing the brunt of the temperature and the condensation it to act. For thisArticle, 20 "square dome (containing a 1" flange on both sides of the 18 "-square dome), 5" tall, and mounted directly on the surface of the metal roof will be used as an example to be covered by the box-like cover storm. Similar coverings are made in proportion to other dimensions of the dome.
Tools and materials (total cost for parts: $ 50-90, depending on the availability of the acrylic plate).
Pressure 2x6x96 'treated boards ($ 5) A 22x22 "sheets of heavy 0.22" thick acrylicPlexiglas ($ 25-60, depending on the internal forces out). If the piece should be cut from a larger sheet, leaving the film on both sides of the leaf, unpeeled, until the saw is made. With a sharp thin blade tooth. Otherwise, leave the power is cut to size for you. Twelve # 12x3 "Phillips screws 20-30 - # 8x1 "drywall screws Philips (head width) Seal a small tube of clear silicone ($ 4) Two silicone tubes sealed windows / door with the similar colored tiles($ 8) Four vertical flat 2-1/2 "L brackets ($ 5) Eight # 10x1 "wood screws (for attaching the L-brackets to the frame coverage) Eight # 10x1-1 / 2 to 2 "wood screws (for securing the frame L-brackets on the roof with the tiles) A liter of oil-based waterproof paint similar in color to match the tiles ($ 4) Tools: electric circular saw, drill, drill bits, screwdriver, caulking gun, trowel, rat-tail file, brush
Cover construction.
Cut 12x6 "square pieces on board in four corners: two 22" long and the two 19 "long.
2 Install the 22 "square box-like frame sealing / securing the four corners of the silicon-window / door seal and water conservation 3" screws.
3 What is the bottom of the bottom side of being, you use the file in at least three crescent grove to make way for the drainage of moisture.
4 paint both inside and outside of the timber frame. Let dry.
5 Place the acrylic paint on plexiglassFrame.
6 Mark the Plexiglas where the holes will be about 5 "around the top side of the frame.
7 For each mark, drill a hole through the plexiglas (only) is wider than the screw drywall.
8 Then, with a small hole 1 / 2 "deep in the dead wood-frame through the holes in plexiglass.
9 Remove the Plexiglas from the frame and determines the fit to the frame.
10 Sweep away any plastic or wood chips from the frame andPlexiglas.
11 Seal with silicone, add a thin bead along each side of the frame around the hole around it.
12 Carefully replace the upper plexiglass frame and set it up according to the original holes.
13 Install the screws of average density, so as not to break the plexiglass. The caulk is spread flat between the frame and plexiglass to seal.
14 Add at least one flat L-shaped brackets on each side of the frame flush with itsFund with 1 "wood screws.
Paint the brackets 15.
Coverage of installation (the easiest).
1 With the use of safety devices, run the lid filled to the roof, provided that the roof is a low-pitch and walked.
2 There on the vaulted ceiling, one place to another.
3 Place the dome on the roof through the tiles with a 1-1/2 to 2 "wood screws, depending on the thickness of the tile.
4 Seal the bottom of the top and the twoThe sides of the lid with silicone window / door seal. Seal the brackets and screws the same way. Let the underside of the lower end was cut for drainage. There is a window of time.
5 If necessary, touch up the frame and the brackets with the color.
By installing the shingles cover the top of the slide of wood under the shingles and all damages moisture is protected. This position also increases the coverage on the bubble for an adequate space.
This coverage takes overThe formation of almost all the condensation that would otherwise occur within the dome is, none of which are through the dome in the cabin or under the shingles. It 'also to protect the dome from hail, branches of fallen trees and other damage. For more information on the types of roof windows and their maintenance, see these pages.
