Our company is regarded as a specialist in offering a huge array of Turbine Air Ventilator. These ventilators are renowned for their sturdy spider type frame construction to withstand adverse weather conditions. Working Principle of  Air Ventilator: The ventilator is combination of both natural & forced ventilation system. It Functions as a natural ventilator when there is a difference in thermal or wind pressure between the inside and outside of the building which Forces the air to move through the opening of the ventilator. Industrial activity generates heat and hot air being lighter moves upwards. The lighter air get accumulated in the turbine of the  Wind Ventilator. As the hot air tries to escape from the turbine, it exerts a backwards thrust on the vanes and sets them in a rotational movement . When the ventilator blades rotate the turbine it gives rise to the centrifugal force and creates a vacuum inside the turbine .The partial vacuum is replaced by strong upward forceful movement of the wind . As the hot air is thrown out, fresh air starts entering through windows and door openings .This works for a perfect exhaust by wind driven ventilator thrown out, fresh air starts entering through windows and door openings.

Metal -faced polyurethane sandwich panels are the system of choice today for large industrial buildings, refrigerated ware houses, office blocks, exhibition halls, fair pavilions, schools and sports halls. The aluminium or steel facings themselves are surface coated and can be manufactured with profiles of various depths leading to a higher load bearing. Polyurethane sandwich panels come complete with specially formed tongue – and – groove joints ensuring a perfect fit and maximum integrity. Assembly is fast, easy and cost effective. The resultant sandwich panel has a load-dearing capability many times greater than that achieved by adding together the load-bearing capacities of the individual layers. As a result, these thin, relatively lightweight sandwich panels can safely bridgewide spans.Puf insulated sandwich panels for roof and wall : These panels functions well as a roof or wall panel when used in conjunction with pre-engineered buildings or conventional steel framing systems. The product features an overlapping major rib at the panel sidelap, this sandwich panel is filled with CFC free polyurethane in the core achieving Good R- Values and consists of exterior and interior facings of relatively thin metal sheet profiled. Panel strength will be more because of double sheet with corrugated profiles with core thickness varies from – 30 – 120 mm thickness. Purlin spacings will be upto 5 m so that steel structure cost in purlin will be saved.

The energy crisis globally has brought about an increase in combustible costs, where only an appropriate insulation system can bring about significant economic savings. The need to insulate buildings at all exposed or susceptible surfaces from inside or outside is an indisputable reality that finally goes on to increasing the comfort of occupants-both temporary and permanent, humans and livestock and finally products and goods that are heat and moisture sensitive And the objective stems from a basic understanding to keep the heat out during summers and to keep the heat in during winters. In order to keep the insulation effective and efficient, it needs to be well protected with a good air and vapour barrier – which Insulation’s products do extremely well.A GOOD INSULATION SYSTEM :The surface that create or make the cover or envelope of any building including it’s sub-structural system is mainly composed of five essential elements: general weather barrier, an air barrier, the insulation, the vapour barrier andthe interior finishing All these together must – *provide thermal resistance * limit air flow * limit diffusion of moisture *allow moisture to evaporate towards exterior from within the envelope. The Product :Our OPTIMUM insulation is constructed with two layers of 10 mm thick fire retardant big air bubble film laminated with both side pure aluminium foil.
