QIIP PANELS WALL FIXING DETAILS

The following can be concluded from the above series of experiments:

Even with 12000C flame burning the Panel for 2 hours, there is no damage to the core of the panel. There is no flashover effect on QIIP WALLS. The PUF core is not affected. However, after 2 hours of constant flaming, the bonding between the GI sheet and PUF core was lost on the side where flaming was done. Direct flame on PUF has shown that it forms a char layer on the surface which is exposed to the flame. This layer prevents the fire from spreading inwards. As the PUF is of high density, there are no air gaps inside the foam. This means that there is very less chimney effect. The foam, even after burning, does not form droplets, which means that, there is no scope of secondary fires.

Although polyurethane is a combustible material, the protective coverings on both sides not only protect the panel from failing but also do not transmit heat to the other side. The aluminum outer frame imparts even more structural stability to the entire panel. The flash point of polyurethane foam is 3100C which means the foam does not ignite spontaneously. From the above observations, it can be said that QIIP WALLS fall under the fire-resistant building material category. QIIP WALLS are green building product and bio degradable.

 Fiber-reinforced polymer (FRP), also Fiber-reinforced plastic, is a composite material made of a polymer matrix reinforced with fibers. The fibers are usually glass, carbon, or aramid, although other fibers such as paper or wood or asbestos have been sometimes used. The polymer is usually an epoxy, vinylester or polyester thermosetting plastic, and phenol formaldehyde resins are still in use. FRPs are commonly used in the aerospace, automotive, marine, and construction industries.

Composite materials are engineered or naturally occurring materials made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct within the finished structure. Most composites have strong, stiff fibers in a matrix which is weaker and less stiff. The objective is usually to make a component which is strong and stiff, often with a low density. Commercial material commonly has glass or carbon fibers in matrices based on thermosetting polymers, such as epoxy or polyester resins. Sometimes, thermoplastic polymers may be preferred, since they are moldable after initial production. There are further classes of composite in which the matrix is a metal or a ceramic. For the most part, these are still in a developmental stage, with problems of high manufacturing costs yet to be overcome. Furthermore, in these composites the reasons for adding the fibers (or, in some cases, particles) are often rather complex; for example, improvements may be sought in creep, wear, fracture toughness, thermal stability, etc.

Fiber reinforced polymer (FRP) are composites used in almost every type of advanced engineering structure, with their usage ranging from aircraft, helicopters and spacecraft through to boats, ships and offshore platforms and to automobiles, sports goods, chemical processing equipment and civil infrastructure such as bridges and buildings. The usage of FRP composites continues to grow at an impressive rate as these materials are used more in their existing markets and become established in relatively new markets such as biomedical devices and civil structures. A key factor driving the increased applications of composites over the recent years is the development of new advanced forms of FRP materials. This includes developments in high performance resin systems and new styles of reinforcement, such as carbon nanotubes and nanoparticles

The fiber reinforced polymer composites (FRPs) are increasingly being considered as an enhancement to and/or substitute for infrastructure components or systems that are constructed of traditional civil engineering materials, namely concrete and steel. FRP composites are lightweight, non-corrosive, exhibit high specific strength and specific stiffness, are easily constructed, and can be tailored to satisfy performance requirements. Due to these advantageous characteristics, FRP composites have been included in new construction and rehabilitation of structures through its use as reinforcement in concrete, bridge decks, modular structures, formwork, and external reinforcement for strengthening and seismic upgrade.

The applicability of Fiber Reinforced Polymer (FRP) reinforcements to concrete structures as a substitute for steel bars or prestressing tendons has been actively studied in numerous research laboratories and professional organizations around the world. FRP reinforcements offer a number of advantages such as corrosion resistance, non-magnetic properties, high tensile strength, lightweight and ease of handling.

The potential advantages present in using FRP composites are:

• Higher strength
• Lighter weight
• Higher performance
• Longer lasting
• Rehabilitating existing structures and extending their life
• Seismic upgrades
• Defense systems
• Space systems
• Ocean environments

Polycarbonate is a polymer with a unique blend of desirable properties. This polymer can be given shape by different processes, which include injection molding, blow molding, extrusion -and thermoforming. Polycarbonate roof sheets are manufactured by the process of extrusion. Polycarbonate roof sheets are commonly called transparent steel due to their wonderful impact resistance and glass like clarity. Following are a few salient properties of corrugated roof sheets:

Polycarbonate sheets possess superb impact strength (Virtually Unbreakable)	Excellent flexural strength hence can be cold curved or even cold bent into simple shapes
Very high light transmission of upto 90%	Superlative fire performance (Self extinguishing) and TAC approved
Light in weight hence easy to handle & install	Available in tailored lengths, hence minimum wastages
High temperature tolerance (from -40°C to +130°C)	Excellent thermal and electrical insulation properties

Being an engineering thermoplastic, polycarbonate sheets can be thermoformed to make them suitable for a host of different applications where high performance is sought in combination with transparency/ translucency. These plastic corrugated roof sheets can also be engineered to suit various innovative applications in the future.
Polycarbonate Corrugated Sheets

Polycarbonate sheets are extensively used in Industrial Applications. These are used for Industrial Sky Lights and North-Light Glazing to provide daylight solutions in Industrial and Commercial Structures. These polycarbonate roof sheets are available in a variety of profiles matching to commonly used industrial roofing sheets that include asbestos cement sheets & metal corrugated sheets, corrugated roof sheets and plastic corrugated roof sheets.

Polycarbonate corrugated sheets can be manufactured from compact clear, embossed or opal white sheets depending upon the amount of light required for the specific industrial application. The light transmission can be as high as 89% or controlled to as low as 35%. These sheets can be offered to the customer as a tailor-made product in terms of dimensions. The process of forming these sheets is generally referred to as Thermoforming

Gypsum board is one of several building materials covered by the umbrella term “gypsum panel products.” All gypsum panel products contain gypsum cores; however, they can be faced with a variety of different materials, including paper and fiberglass mats.
Gypsum board is often called drywall, wallboard, or plasterboard. It differs from other panel-type building products, such as plywood, hardboard, and fiberboard, because of its noncombustible core and paper facers. When joints and fastener heads are covered with a joint compound system, gypsum wall board creates a continuous surface suitable for most types of interior decoration.
Advantages of Gypsum Board Construction
Gypsum board walls and ceilings have a number of outstanding advantages:

• Ease of installation
• Fire resistance
• Sound isolation
• Durability
• Economy
• Versatility

Ease of installation
Gypsum board building systems are easy to install for several reasons. Gypsum board panels are relatively large compared to other materials. They come in 48- and 54-inch wide sheets and in lengths of 8, 10, or 12 feet, so they quickly cover large wall and ceiling areas. Gypsum board assemblies require only a few tools for their construction. Gypsum board can be cut with either a utility knife or a variety of saws, and it can be attached with a variety of fasteners, including screws, nails, and staples. It can also be adhesively attached to many substrates. Gypsum board is a lightweight material. Two workers can easily handle most panels and cover large areas in very short time periods. Gypsum board is easily finished using either a few hand tools or relatively modest machines. Gypsum board installers can quickly learn most application techniques in a few hours.
Fire resistance
Gypsum board is an excellent fire-resistive building material. In North America, it is the most commonly used interior finish where fire resistance classifications are required. Its noncombustible core contains nearly 21% chemically combined water, as described earlier, which, under high heat, is slowly released as steam. Because steam will not exceed 212 degrees F under normal atmospheric pressure, it very effectively retards the transfer of heat and the spread of fire. Even after complete calcination, when all the water has been released from its core, gypsum board continues to serve as a heat-insulating barrier. When installed in combination with other materials in laboratory-tested wall and ceiling assemblies, gypsum board serves to effectively protect building elements from fire for prescribed time periods.
Sound isolation
Preventing the transfer of unwanted sound to adjoining areas is a key consideration when designing a building, specifically when taking into account the intended activities of the occupants in the various parts of the building. For example, a building containing office spaces adjacent to manufacturing facilities requires more noise-reducing features than are typically necessary in a building that has only office space in it. Gypsum board wall and ceilings systems effectively help control sound transmission.
Durability
Gypsum board is used to construct strong, high quality walls and ceilings that offer excellent dimensional stability and durability. Surfaces created using gypsum board are easily decorated and refinished.
Economy
Gypsum board is readily available and easy to apply. It is an inexpensive wall surfacing material that provides a fire resistant interior finish. Gypsum board building systems can generally be installed at significantly lower labor costs than most alternate systems.
Versatility

Gypsum board satisfies a wide range of architectural requirements for design. Ease of application, performance, ease of repair, availability, and its adaptability to all forms of decoration combine to make gypsum board unmatched by any other surfacing product

Stainless steel is great for creating durable and attractive products. Our laser cutting technology allows you to achieve a level of precision and build quality at unbeatable value. Build stunning art pieces, unique decorations, house appliances, and virtually anything you dream up.
Leesha Fabritech is equipped with the innovative pulsed laser technology which allows for accurate cutting of sheet metal. Commonly cut metals include stainless steel, mild steel and aluminum.
Clean and Accurate Cut
A high pressure assist gas, such as oxygen or nitrogen is injected through the metal cutting nozzle. The result is a dross free cut edge which requires little to no deburring. A pierce dwell and variable pierce assist pressure are adjustable within the laser software. The servo motor motion system is capable of tight tolerances and accurate positioning
Low Operating Cost
Laser cutting is a non-contact process that eliminates the high costs of replacement die stamps, machine center re-tooling and router bits. Laser users also benefit from low electrical and maintenance costs. Our laser software contains money saving features such as the ability to turn off the gas assist while the laser head is moving between parts. This will ensure consumable costs are kept at a minimum.
Intricate Cutting
Our metal cutting machines are capable of cutting thin gauge metals with detailed designs. A laser beam cutting kerf of just .004” allows for the most intricate of cuts to be made. These tasks are often difficult or impossible to perform with a high powered kW laser as they are unable to cut with a stable power level resulting in blow-outs or heat affected zones.
