Roof waterproofing works After their implementation, the necessary test is carried out and to ensure that there are no observations or leaks in the At the same time, the supply and installation of ducts for central air conditioning, concealed «Concealed» and desert air conditioning, if any, is carried out, provided that The work of installing ducts after the waterproofing test allows us to watch the leaks, God forbid, if they exist in the ceilings, and if the «ducts» as well as the borrowed ceilings «gypsum» are installed before the waterproofing test, when any leaks occur from the insulation, it is impossible to see them.
<p class=«p1The air conditioning plan is prepared by the air conditioning contractor in accordance with the design of the gypsum ceilings, which is prepared by the interior designer "decorative engineer« and emphasize the importance of reviewing the air conditioning duct plan by the interior designer before starting implementation in order to match it with the gypsum plans and approve it
Care must be taken to review the decorative plans for borrowed ceilings »gypsum and others«, provided that the plans include the locations of lighting openings, there is no doubt that lighting plays an important role in the aesthetics of the space and the building in general, the lighting plan can be implemented in accordance with the design of borrowed ceilings by the interior designer, or by specialized agencies in lighting.
The lighting plan can be implemented by the interior designer, or by those specialized in lighting.
The duct sheeting is supplied to the site and executed according to the plans, emphasizing the importance of good duct insulation and observing the specifications specified in the contract, which are usually according to the American Society of Heating, Refrigeration and Ventilation Engineers ASHRAE Standard Specifications (ASHRAE) as well as the specifications of the building's air conditioning, refrigeration and ventilation system.
After that, the implementation of the borrowed ceilings is started, usually gypsum is used as we can use gypsum board, ordinary gypsum is characterized by the possibility of molding it and implementing all designs in it no matter how many decorative details and carvings, gypsum board can also implement multiple designs in it and is ideal if the ceilings have designs that do not have many decorative details, bends and so on.
After that, the implementation of the borrowed ceilings is started.
When there are borrowed ceilings exposed to external weather factors, it is recommended to use moisture-resistant gypsum board or cement board, as it has high resistance and this contributes to extending its lifespan without being affected, and care must be taken to contract with a specialized body to carry out plaster work or a specialized contractor, with the need to make several quotations and choose the most appropriate one, specifying the method of installation and specifications And the thickness of the gypsum tiles, and writing a contract on the official paper of the executing entity with the need to specify the prices of all works and the method of calculating the costs, whether for ceilings and also for wall decorations, if any, noting that wall decorations are implemented later when the floor tiles are completed to avoid the contact of gypsum or gypsum board with the mortar and this contributes to the arrival of moisture and the impact and damage of gypsum and peeling paint.
Regular gypsum is used in rooms, halls, etc., and moisture-resistant gypsum known as French gypsum and moisture-resistant gypsum board is used in places exposed to moisture such as kitchens, restrooms and laundry rooms, and gypsum is installed and hung in two ways, the first: Using pistol bullets, hair and metal wire, the second: using metal mesh, which is the best and the most expensive and is recommended for large areas as well as when the borrowed ceiling drops more than 25 cm from the concrete ceiling when there are air ducts "ducts", also gypsum board and cement board are installed using metal mesh.
