Skylight-Homemade shallow box-shaped acrylic condensate cover for dome installation

Today, acrylic or polycarbonate dome windows come in a variety of sizes. However, the traditional one has a square to rectangular shape and is about 5 inches long. It ranges in width and length from 12 inches to 36 inches and is 1/8 inch thick.
These domes can be attached to wooden curbs (2×2 “to 2×6”) that wrap roof tiles to prevent rain from leaking or attach thin metal flashes. These domes can also be attached directly to tar paper or a wooden sheet beneath the shingles. In the latter case, the dome around the shingles is placed directly on the flat outer flange, just as shingles is usually on flat metal such as roof openings, kiln chimneys, barrels, sewers, etc. Will be It will be laid. This installation lowers the height of the dome.
problem. In any case, no matter how the dome is mounted or with a plastic screen inside, unwanted condensation and similar leaks can occur. These domes are also vulnerable to cracks due to large hail, limb drops, earthquakes, or inadvertent roof coverings. When these events occur, the skylight leaks rainwater in addition to the formation of moisture.
Solution. A 5-1 / 2 “height, transparent, shallow acrylic tube manufacturers box-shaped canopy is constructed and installed on top of the dome. This canopy withstands most changes in temperature and most condensation formations, resulting in a storm. Acts as a window for this item, a 20 “square dome (including 1 inch flanges on each side of an 18 inch square dome), 5 inches high, a surface attached directly to the roof sheet, It is used as an example of covering with a box-shaped storm cover. Similar enclosures can be built in proportion to other dome sizes.

Roof construction.
Cut a 1.2×6 inch board into four square corner pieces. It is 222 inches long and 219 inches long.
2.2. Install the 22 “square box frame by sealing / fixing the four corners with silicone waterproof window / door paint and 3” screws.
At the bottom of the bottom, use the file to make at least three crescent-shaped bushes to drain water.
4. Paint the inside and outside of the crate. Let it dry.
5. Place the acrylic plexiglass on the frame.
6. Mark the plexiglass with the screw holes about 5 inches away from the top of the frame. 7. Drill holes at each point on plexiglass (only), which is wider than drywall screws.
