Vision d'O glossary

• Glass swimming pool: swimming pool of which one or more sides, or whose bottom is made of glass 
• Glass swimming pool wall, other name, glass swimming pool panel, glass wall 
  • 3-sided swimming pool wall: configuration, where the sheet of glass or PMMA (acrylic glass) is enclosed in the U-shaped rebate (bottom + sides), leaving one side free. The free side of the glass sheet provides an extraordinarily graphic, light and designer dimension. 
  • 3-sided overflow swimming pool wall: 3-sided swimming pool configuration characterized by a thin sheet of water of approximately 3mm which flows below the pool, by overflow action. 
  • Corner pool wall: configuration, where two glass or PMMA walls form an angle. 
  • Outgoing U-shaped wall: Configuration combining 3 glass walls (glass or PMMA) forming a U containing the pool water. 
• U-shaped re-entry wall: Configuration combining 3 glass walls (glass or PMMA) forming a U-shaped re-entry into the pool remaining out of water. 
• Vertical swimming pool window, other name Swimming pool porthole, aquatic or underwater window. 
  • Any configuration where a sheet of glass or PMMA (acrylic glass) is enclosed on all 4 sides in an L-shaped rebate. 
  • The transparent sheet, completely enclosed in a frame, then takes on the appearance of a window. (round, rectangular or free shape, depending on the customer's tastes). 
• Horizontal window, other name glass swimming pool bottom, glass bottom, glass swimming pool floor 
  • Any configuration where a sheet of glass is integrated into the bottom of a swimming pool, with a grip on all 4 sides and enclosed in an L-shaped rebate. 
  • One side of the glass is exposed to water, the other to air.
• Typology of way of inserting the glass 
  • Frameless: without frame 
  • Window with stainless steel frame: any configuration, where the glass sheet is enclosed in a stainless steel frame 
• Submerged window: window which is located partially or completely in the water. 
• Continuous immersion: the submerged part of the window always remains underwater. 
• Waterline: limit between the submerged part and the emerged part of an object when it is in the water. Our walls give you access to vision below this waterline. 
• Mirror pool: this type of pool is characterized by the overflow of water on all sides of the pool. Thus, with its completely flat, smooth and shiny surface, the water reflects the sky and gives this “mirror” appearance.

• Hydrophobic material: material that remains waterproof, which does not mix with water 
• Tempered glass: glass heat-treated by rapid cooling processes, “tempering”, with the aim of increasing its resistance to shocks. Tempered glass is two to five times stronger than ordinary glass. It is part of safety glass. 
• Laminated glass: glass made by assembling two (or more) sheets of glass using plastic films: SentryGlas interlayer. From the safety glass family. 
• Transparent polymer: substance composed of macromolecules and derived from molecules of low molecular mass. The polymer used at Vision d’O is PMMA, it has a higher light transmission than that of glass.
• Extra Clear Glass: glass characterized by very low coloring and excellent light transmission, thanks to its very low iron oxide content. 
• PMMA: highly transparent thermoplastic polymer, obtained by polymerization of methyl methacrylate monomer. Its transparency and its visual appearance mean that PMMA can be considered as an alternative to glass. It is sometimes called acrylic glass or Plexiglas. Compared to glass, PMMA is ten times stronger, lighter and more transparent. On the other hand, PMMA is more sensitive than glass to scratches while being easier to polish, to make them disappear.
• Chemical welding of PMMA: delicate physico-chemical process which aims to join two PMMA plates. The welding is almost imperceptible. 
• Marie Louise screen printing: The Marie Louise screen printing is a digital printing made on the edge of the glass for a perfect visual rendering, choice of shade adapted to the color of the interior covering of the swimming pool (manual for PMMA). 
• Sealing products: all products used to treat the sealing of the junction points between the glass wall and the structure in which it is integrated and thus preventing any risk of water leakage. 
• Polished flat joint: finishing of the edges of the glass obtained by shaping and characterized by edges beveled at 45° over a width of approximately 1 mm. This type of finish allows you to obtain a edge with a perfect aesthetic appearance, while avoiding any risk of cuts on the edge of the glass. 
• Rounded edge: Finishing of the upper edge of the wall characterized by a rounded shape, this type of finishing can only be achieved on PMMA. 
• Cutting: action which consists of cutting the glazing to obtain the desired shape. 
• Simple shape: we designate a simple shape, any regular shape (rectangle, square, round, triangle, etc.), which can be identified by ribs as opposed to a complex shape which requires a template. 
• PMMA Stainless steel frame: PMMA window with mechanically sealed frame allowing the integration of a window with an incompatible frameless coating.

• Reinforced concrete: Reinforced concrete is a composite material made up of concrete and steel bars which combines the compressive strength of concrete and the tensile strength of steel. 
• Stainless steel: Stainless steel, commonly called stainless steel or inox, is a steel with more than 10.5% chromium, the property of which is to be little sensitive to corrosion and not to degrade into rust. 
• Reinforced PVC: swimming pool covering membrane, made up of two layers of flexible PVC, between which a polyester frame is positioned. This coating is thicker than a traditional liner. Also called reinforced membrane. 
• Earthenware: in the context of our activity we designate by earthenware any covering in the form of tiles (tiles, glass paste, natural stone, etc.) 
• Gelcoat: a gelcoat (from the English gel coat) is a thermosetting resin-based material, used to provide a high finish and protection of the visible surface of the swimming pool.

Interview :

• Winterizing a swimming pool: set of necessary precautions to take for the maintenance of a swimming pool, due to the risk of freezing, during the winter. 
• Scratches: slight marks that may occur during the life of a wall. These scratches can be caused by metal objects (jewelry, watches, swimsuit cords, etc.). 
• Cleaning: operation which consists of removing dirt in order to ensure the cleanliness, hygiene, aesthetics and maintenance of the swimming pool, for glass surfaces a clean sponge and glass product are recommended for cleaning the walls of the swimming pool. glass. 
• Polishing: operation aimed at eliminating scratches present on the walls. 
• Limestone: sedimentary rocks, mainly calcium and magnesium carbonate. which enrich the water on contact. 
• Water pH: pH measures the acidity or basicity of a solution. Thus, in an aqueous medium at 25°C: a solution of pH = 7 is said to be neutral; a solution with a pH < 7 is said to be acidic; the lower its pH, the more acidic it is; a solution with a pH > 7 is said to be basic; the more its pH increases, the more basic it is. In the swimming pool, the ideal pH should be between 6.8 and 7.2. 
• Leak: water flow due to a sealing problem between the wall and the structure of the swimming pool. 
• Surface flatness: quality of a surface that is perfectly flat, without significant scratches or deformation. 
• Visual distortion: alteration of visual perception that results in distortion of objects or shapes. On an aquatic window, it can be caused by scratches or dents. 
• Seal repair: process of replacing, repairing or restoring the seals of the aquatic window. This often involves removing old, worn gaskets, followed by applying new ones to ensure a tight seal.

• Polymerization: chemical reaction that allows sealants to acquire their optimal properties. (polymerization time: minimum time to be respected before filling the pool with water so that the watertightness of the pool is ensured.)

• Observation pool: water pool specially designed to allow the observation of certain activities or phenomena, generally in a scientific or research context. Most of them are designed with transparent walls to facilitate underwater observation. 
• Sports pool: certain competition pools and municipal swimming pools now include transparent walls to offer coaches a perspective and a clear view of the athletes' performances. Through these windows, coaches can analyze swimmers' movements in real time, identifying necessary adjustments to maximize their potential. 
• Tank window: aquatic window, often round, placed in a tank to observe a phenomenon or liquid. 
• Dolphinarium: establishment specially designed to house and present dolphins and other cetaceans in captivity. These facilities, usually found in wildlife parks, offer shows where dolphins perform acrobatics and tricks under the guidance of trainers. Transparent walls are most often installed in order to make the view more fluid and observe the behavior of these animals underwater. 
• Oceanarium: giant aquarium specially designed to accommodate and exhibit a wide variety of marine animals living in different ocean ecosystems. It aims to realistically recreate natural marine habitats. Designed with transparent walls, this offers visitors an immersion in the underwater world.
• Anti-flood barrier: Certain buildings close to a water point present a risk of flooding. Barriers exist, made of glass, they help retain water while not obstructing the surrounding landscape.

• Continuous underwater pressure: pressure exerted by water on an object submerged at a given depth. This pressure is constant and continuous in the sense that it acts uniformly especially on the surface of the submerged window. 
• Hydrostatic pressure: thrust exerted by water on the surface of a submerged body. 
• Pressurized environment: environment in which the pressure is greater than normal atmospheric pressure. 
• Water column: height of a body of water measured vertically from the bottom of the aquatic window to the water surface. This measurement is used to assess the pressure exerted by the water column on your aquatic window and determine the wall thickness 
• Heat Soak Test (HST): test which aims to detect, after tempering, glasses that may be subject to spontaneous breakage before they are used. This test consists of an additional heat treatment (destructive in the case of defective glass) in specific equipment (heat soak test oven).
