PUF Panels

Being one of the leading manufacturers and suppliers of these Polyurethane Insulated Panels, we engage in using the finest raw materials that are available in the market. For the purpose of maintaining its quality, we abide by the industrial guidelines. Its high insulating capacity, commendable sturdiness, and superior lifespan, makes it highly praised and preferred amongst clients. We offer an extensive range of Polyurethane Foam (PUF) insulated panels, which are suited for a vast range of applications such as cold storages, packing houses, cold chambers, banana ripening chambers, and freezer rooms, etc. PUF panels are manufactured in a computerized plant and come in prepainted galvanized steel sheets (PPGS) and stainless steel fascias. In this, the density of Polyurethane Foam (PUF) sandwiched between two fascias is 40 ± 2 Kg/M3. These insulated PUF panels offer long-lasting value with controlled quality, accuracy & speed of construction.

PROJECTS

The PUF sandwich panels are manufactured in compliance with the set industrial norms and guidelines. The high-quality raw materials used in its fabrication give the panels a commendable structure, superior strength, and extraordinarily long life. It is used widely for building roofs and walls in several industries.

SFT’s panels have a close-celled polyurethane core eliminating any possible moisture accumulation and offering a higher thermal value per meter. These polyurethane panels have no organic skeletal elements, which are common sources of mold and warping. The polyurethane insulated panels are made out of two 26 or 24 gauge galvanized steel sheets covered with a white polyester enamel. Panel joints used along with integrated cam locks provide water-and-vapor-proof seal required for all types of environments. In addition, the elimination of thermal bridges results in efficient insulation which leads to reduced energy costs

FEATURES

  • Modular in nature and pre-engineered for precision and simplified construction.
  • Walls of different height, yet sturdy and robust construction.
  • Light-weight panels which are easy to lift and erect at any height inside the plant or any other place.
  • Frameless construction and ease of design, supply and erect for any type of construction.

BENEFITS

  • It provides excellent thermal insulation.
  • Construction pre-engineered and fewer components, internationally accepted and meets or exceeds all building code specifications.
  • Higher energy savings due to very low thermal conductivity.
  • Flexibility in design and choosing various options on fascia of panels and colors.
  • All weatherproof construction and maintenance-free.
  • These insulated panels give long-lasting value with controlled quality, accuracy & speed of construction and cater for better functionality and application.
  • These have been made as per the International standards and are completely eco-friendly.
