Water Proof Polyurethane Sandwich Panel is the best material for heat and sound insulation. It can reduce the heat transmission caused by difference in the internal and external temperature, and get to maximum efficiency of freezing and refrigeration systems. It is a new type of heat insulation material for lower construction cost.Panels are in multiple varieties and specifications to meet the need of various sites and projects.

Product Introduction
Water Proof Polyurethane Sandwich Panel is widely used as an external cladding for single and multi-storey buildings, where they are
required to provide weather resistance, and resistance to wind-loading, access loads, self-weight and so on. However, they are also used
to create insulated internal envelopes, ceiling panels, partitions (for example in cold stores) and for fire-resisting compartment walls.

Water Proof Polyurethane Sandwich Panel, referred to as PIR board, is a sandwich board made of PIR as the insulation core material
and double-sided color steel. It uses the excellent self-adhesiveness of the PIR foaming process and is continuously formed on an
automated production line. It has high dimensional stability and high flame retardancy.
In times of high energy costs, our roof panels with a highly heat-insulating core of polyurethane rigid foam are the first choice.You can
thus satisfy the highest requirements for heat and moisture protection and sustainably protect your building.
Core materials: Water Proof Polyurethane Sandwich Panel
Rigid polyurethane foam is the most environmentally friendly insulation materials in the world.
Compared with other roof panels, our aluminum roof panels are water proof ,fire proof,and eco-friendly.
Surface material: Aluminum Plates

THE DIFFERENCE BETWEEN PIR AND PUR
PUR and PIR are both types of rigid polyurethane foam, but there are significant differences in their chemical and physical properties.
Polyurethane rigid foam is mainly composed of polyols and isocyanates. Polyols are further divided into polyether polyols and polyester
polyols. The product produced by the reaction of polyether polyols and isocyanates is PUR, while polyester polyols and isocyanates undergo trimerization to produce polyisocyanurate (PIR).
The production process of PUR and PIR is different, and the product performance may vary. PIR foam has more excellent and stable performance. Compared with PUR foam, PIR foam with the same density has much higher compressive strength than PUR.
PIR has better flame retardancy and low smoke properties than PUR. Therefore, it is mainly used for building insulation.
PIR has good heat resistance. It can be used for a long time in an environment of 150 ℃, with a size change rate of less than 1%. The temperature
is higher for short-term use. If ordinary polyurethane rigid foam is used at this temperature for a long time, its strength will gradually decline, and its appearance and size will also change.
