INSULATED POLYURETHANE SANDWICH PANEL

 

We manufacture insulated polyurethane sandwich panels(which are )designed with interlocking joints and PVC sash. This so-called ‘brim’ style is distinguished from ‘exposed fastener style,’ in which a panel’s interior structural material is exposed.

 

Our sash panels forming the walls and ceilings of cold storage feature interlocking joints, which make the finished structure extremely solid and durable in and of itself.

 

Since the beginning of 2016, the demand has been growing for panels designed to accommodate ultra-low temperature or ultra-low/ high pressure inside cold-storage, and special engineering laboratories such as wind-tunnel testing labs. In responding to such a demand, we developed and began to mass-produce brim-style panels with hidden interlocking joints, which reinforces the physical strength of assembled structures.

 

 

(1) Advantages of PDS brim-type panels


① Our “brim style” panel features a seamless assembly of metal surface and PVC borders for superior vapor tightness. This effectively prevents cooling compartment’s condensation from leaking into the panel interior, ensuring durability and sustainable high performance

 

② Our panel’s integrated design increases the panel’s maximum structural load to prevent warping. This also allows for installation without requirement of additional structural reinforcement.

 

③ Thermal warping of cold storage panels can occur when materials composing the panels (steel, stainless steel) expand and contract at different rates. Sandwich panels installed for freezers are subject to thermal bowing, which occurs because the warm metal side expands and the cool metal side contracts. Our ‘brim type’ panel with its seamless assembly of surface metal and PVC sash, prevents the occurrence of such thermal bowing

 

④ Wall panels and ceiling panels interlock in T joints for increased durability. This type of joints has superior capacity to maintain shape. And as such, extra-long panels can withstand the internal pressure of storage compartment without additional structural reinforcement.

Superior insulation values

  • Superior vapor-tightness prevents cooling compartment’s condensation from leaking into the panel interior, ensuring durability and sustainable performance.
  • Our sandwich panels provide an economical means to meet our client’s thermal requirements since rigid polyurethane foamed in place as core material ensures near-zero air permeability to deliver superior energy-efficiency.

 

Extensive line of products

  • Our sandwich panels are designed and manufactured to meet our client’s various thermal, structural, and architectural requirements. The variety of core thickness, material, size, shape, and color options to choose from help create finished products that guarantees satisfaction.

 

 

Simple assembly and installation

  • Panels and doors are custom-fabricated according to the highly detailed design templates created by our experienced staff who evaluate client’s particular application and site requirements in advance. Installation is fast and easy because our panels come completely finished and require no additional processing on-site. This reduces construction time by over 1/5, as well as costs of expansion and moving.

 

Durability

  • Our foamed-in-place polyurethane panels provide superior durability with seamless PVC border design, which ensures the tightest possible seal against air and moisture penetration into the panel interior and reinforces load bearing capacity to prevent warping. This eliminates the need for additional structural reinforcement during installation.
