The beautiful exterior cladding is made from sustainably-sourced cedar, and the option of a sedum roof is available to make the structure fit in seamlessly into its surroundings. This system is widely used to achieve positive drainage when the structure or subdeck is not adequately sloped to drain. You can’t have drainage without a drainage gap. The traffic surface protects the waterproofing membrane or the "water control layer." And just as important, there is a drainage gap above the water control layer/waterproofing membrane. Wow. You drain the traffic surface and you also drain the water control layer. Because of the relatively high aggregate content, excess free water is used in pouring the deck. If you have any questions about this project, feel free to contact me. Baiyoke Tower II - Wikipedia, The Free Encyclopedia With the antenna included, the building's height is 328.4 m a 360-degree revolving roof deck on the 84th floor and the hotel offers 673 guest rooms.

Ballasted roofs are rarely used, since the deck systems are designed for lightweight roofs and the inertia effect of ballast under seismic conditions might destroy the building's integrity. However, that construction work might not translate well to making a strong, and safe composite deck because if you have several people on it at once, you do not want it to fall and break, hurting your friends, family and even children. These fibrous decks generally have a gypsum-like or cementitious binder and combine the functions of a roof deck, thermal insulation, and finished ceiling. While gypsum is rarely installed in new construction today, there are still structures around with these old decks. Now some of you folks who are older than Aaron Rodgers2 will recognize double-drains from old plumbing textbooks. Although Charlotte is currently seeing a brief rest from the downfalls, you can be sure that a fresh supply of that glittery liquid refreshment will accompany the balance of the Fall season. Be sure to make the front roof triangle flush with the rest of the house. When a roof is constructed to be unvented, it must be designed to control condensation.

Rainwater control at its best. DURANAR SPF IR reflective coatings are multi-coat systems consisting of a nominal 0.2 mil corrosion inhibitive primer, a 0.75 mil fluoropolymer topcoat, and a 0.5 mil clearcoat, when applicable. Steel decks are produced with galvanizing for corrosion resistance, or a thin layer of coating called "shop-primer." The primed deck is not very corrosion resistant, so the Rosemont, IL-based National Roofing Contractors Association (NRCA) recommends that owners always specify galvanized decking. The Westford, MA-based National Roof Deck Contractors Association has published guidelines for rehabilitation of old gypsum decking. It’s how old guys used to do shower Sump Pans (Figure 2). Plumbers figured out this stuff before roofers figured out this stuff, and before Max Baker put it down in writing for the rest of us. Figure 1: A Max Baker Classic-I just love this figure. Single-ply membranes may be fully adhered to wood product decks since the membranes are capable of accommodating the deck movement.

Because these decks are porous, roofing cannot be adhered directly to the deck. While steel decks are termed "non-nailable," they are generally roofed by using screws or special penetrating fasteners to anchor a layer of gypsum board or board insulation. Generally, a base sheet is mechanically fastened, using a specially designed divergent fastener for wind resistance. FM global has recently updated information on fastening patterns for adequate wind resistance. If the deck is badly corroded, these sections should be replaced at the time of re-cover, as the corroded deck may not provide enough fastener withdrawal resistance. With today’s energy demands, additional thermal resistance is achieved by embedding water-resistant polystyrene foam in the poured fill. Coated base sheets are nailed to the fill using special diverging fasteners designed for this type of decking. Because the gypsum was prone to developing cracks, it was treated much the same as wood fiber by using mechanically fastened base sheets. A good way to curb this is by having a layer of thick plastic sheets placed on the ground before applying the pebbles or granite stones.
