We offer 6 products series: Lotos, Komfort, Peony, Edelweiss, Contour and Elegance, comprising 60mm, 70mm, 88mm, 107mm, 108mm and 127mm profile for sliding and combined windows and doors. DIMEX provides high-UV resistant white profiles, color coated profiles, colored body profiles. We have cooperation with international well-known enterprises, such as US DuPont, Renolit, SABIC, which provides high quality color products for construction windows and doors.
the window profiles also known as frames are made of upvc the new age framing material rated far better than wood and aluminium the world over Upvc windows now have all the ingredients needed in window frame .thermal insulation, weather endurance, UV resistance, strength, termite resistance fire Retardant properties, low maintenance, aesthetics and finish are all benefits of upvc windows.Upvc or unplasticised poly vinyl chloride is a product of Natural resources fifty seven percent salt and forty three percent oil. The manufacture of upvc requires minimal use of energy far less than the energy spent on the manufacture of aluminium or steel. Because, of the way these windows are designed and built today all that should filter through is sunlight no dust or Pollution or noise should pass through the upvc window .this window system should be air and watertight if it is installed correctly
Upvc windows have better thermal insulation properties than aluminium in an air conditioned room a properly designed window made of upvc can actually save thirty percent energy this is the expert view of Professor NK Bansal author of energy efficient windows. Professor Bansal defines an energy efficient window as one that consists of a heat insulating framing material, double glazed and proper sealing between the wall and window.
Noise pollution is a major urban problem, noise enters your home through cracks in your walls and gaps in your windows but test have shown that noise pollution can be reduced as much as thirty five decibels after installing upvc windows.
tall buildings need special windows that can with stand in accordance with British standards upvc windows should withstand 1200 Pascal’s or wind gusts of one hundred and sixty kilometres per hour with negligible deflection
The heat transfer coefficient of each specifications are as follows.
Three-cavity Casement Window Frame Uf =1.7W/m2.K、
Four-cavity Casement Window Frame Uf =1.6W/m2.K；
Five-cavity Casement Window Frame Uf =1.5W/m2.K；
During the manufacturing process of the raw materials heat stabilisers are added for material preservation, impact modifiers for toughness, UV stabilizers for resistance against fading and lubricants and oils for better extrusion .the process of manufacturing then continues onto fabrication which is a ten step process of precision engineering. This process includes cutting the frames to length, routing for hinges and locks, reinforcement fitting .this is when the steel reinforcement is installed inside the extruded Upvc frame, fusion welding. This process involves the pre-cut frames with the reinforced steel already installed being placed into a special fusion welding jig, immense heat and pressure welds the corners together, corner cleaning. This process removes the excess welded material known as flash, assembly .rubber seals are added at this point then glazing and then final assembly before packaging. The manufacture of precision engineered upvc windows is only the first step the other is installation
