  • Urethane panel for refrigeration
Using polyisocyanurate foam (PIR),
which has the highest insulation quality among heat insulators, urethane panels
are perfect self-assembly insulation and flame-resisting panels with superior
property.
These panels have better flame resistance,
heat resistance and produce less smoke to
maintain the advantages of PIR.		 High-quality polyurethane panel equipped with the best insulation

High insulation quality

We use panels with excellent insulation qualities whose wall thickness is 1/2 or less of those used in construction.

Energy saving

As these panels have an insulation capacity about six times greater than concrete buildings, they have the capacity to produce warmth quickly and substantially and can reduce the amount of energy wasted.

Light and strong durability

These panels possess the virtues of being practical, strong, durable and resistant to corrosion.

Stable quality management

These panels are being manufactured under strict quality management at a factory for specialized production based on 15-years of accumulated knowledge and technologies related to urethane.

High stability

Doors have double safe escape devices for users’ safety.

Swift and accurate worK

By working speedily and dealing with all aspects of the work process efficiently from orders to deliveries, the entire working period has been greatly shortened

Easy dissemble / relocation and expansion work

By using simple structures and employing convenient working methods, processes such as disassembly,
relocation and expansion are possible at any time.
Best customer service

We produce panels of three colors; ivory, vine pattern and silver, to give customers a greater choice and we try to
make sure that the best follow-up and most advanced service is provided.

Used special urethane glues

The air tightness of panels has been improved using special urethane Burim for joints,
instead of plastic injections.
Energy saving

The insulation quality is six times better than concrete structures
and this greatly improves the warming effect and reduces energy waste.
New PVC coating steel plate

Using embossing coating steel plates with luxurious patterns,
the quality of products has been upgraded.
Adopted a new assembly way

Assembling methods unique to Leehwa Polytech have been adopted and commercialized.

New assembly subsidiary materials for

A new saw-tooth-type joining material (staple) is used for the easy assembling of panel joints.

Adopted an all-in-one door

All-in-one doors are used for the easy assembling of panels, instead of a separate type.
Maintain the best insulation

Goods are produced under strict management in order to enhance the insulation capacity of panels.
