Sandwich Panels for Cold Storage | KoolKeeper Brooklyn NY

Polyisocyanurate (PIR Premier) panels

 PH Insulation sandwich panels with the polyisocyanurate PIR Premier core are used in 20 countries all over the world for construction of cold rooms, warehouses, cold storages, manufacturing buildings, distribution centers and other fast-build construction. With thermal conductivity at 0,0194 W/mK the PIR Premier panels have the best characteristics among the hydro and heat insulation materials.

Polyurethane foam (PUR Classic) panels 

Polyurethane foam PUR Classic sandwich panels are designed for the construction of refrigerating Walk-in Boxes, small warehouses, heat-insulation of industrial facilities, construction of technical and auxiliary buildings. They have the elevated hydro and heat insulation properties, are economical and easy to mount. They can have smooth or profiled surface of any RAL color.

Eccentric Lock Sandwich Panels 

Sandwich panels with insulation PUR Classic (PUR "Classic") on Italian eccentric locks - three-layer panels with tightening locks made in Italy. Thermal insulation is provided by rigid PUR Classic polyurethane foam from international chemical concerns.

Mineral wool sandwich panels 

Mineral wool sandwich panels - three-layer panels with thermal insulation from fire-resistant mineral wool. ProfHolod sandwich panels with fire-resistant mineral wool will allow you to quickly build retail and sports facilities, gas stations, storage, agricultural and industrial premises with high fire safety requirements.

SIP panels 

SIP panels are the three layer panels made of OSB panels with the polyurethane foam filler. SIP panels are used for the construction of “Canadian technology” houses. The panel thickness is from 124 mm to 230 mm. The maximum panel size is 1 250 mm x 2 800 mm. The panels have the exceptional energy saving properties and excellent strength. Houses built of SIP panels create comfortable living in any climatic conditions.

WHAT IS PU? 

Polyurethane foam is a lightweight and durable material that was invented in 1937 in Germany. Polyurethane is made up of small closed cells. 3% of its volume is solid material, and 97% — cells filled with gas. As a result polyurethane foam perfectly holds the temperature you need: thermal conductivity of gases is lower by tens and hundreds times compared to solid materials.

PU

Delivers thermal conductivity of up to 0.020 W/(m*K), and with advanced blowing agents up to 0.018 W/(m*K)
Eco-friendly: used everywhere, from the sole of your shoes and steering wheel in a car to insulation of spacecrafts’ fuel tanks
Hygienic: used in cold storages for food
Steamproof
Resistant to mold, mildew. And no rodents or insects: they just don’t eat it
Preserves unchanged thermal conductivity and other values over time, up to 50 years

HOW IS PUR DIFFERENT FROM PIR?

Polyurethane foam (PUR) and polyisocyanurate foam (PIR) are related polymers of rigid polyurethane foams, which are created as a result of several components’ reaction.

Compared to PUR systems, PIR foam has reduced flammability. Under the influence of flame the outer layer of PIR is charred to form a porous carbon matrix that protects the inner layers and prevents them from burning.
Insulation sandwich panels with PUR Classic are mainly used for the construction of refrigerating and freezing rooms. PUR sandwich panels are also used to build warehouses in earthquake zones: for added strength, these panels can be fastened with eccentric locks.
PIR or Polyiso has more universal applications. PIR Premier sandwich panels are used to build

Refrigerators, cold and freezing rooms
Vegetable and fruit storages
A variety of agricultural facilities: cowsheds, pig farms, poultry houses, etc
Logistic facilities, refrigerated warehouses
Production and office buildings, workshops
Service stations, hangars

Sandwich panels with PIR Premier are also used to modernize and improve energy efficiency of buildings constructedfrom other materials.

LET’S COMPARE THE NUMBERS 

In terms of thermal insulation properties, polyurethane foam surpasses characteristics of standard building materials, such as brick or concrete, by 15 times. A sandwich panel with PUR or PIR insulation 100 mm thick retains heat or cold as a 1.5 meter brick wall.

PU	EPS	Mineral Wool	Cinder Blocks	Bricks
Thermal conductivity	0,022	0,038 - 0,052	0,041	0,160	0,370
Thickness, mm, to retain the needed temperature on the same level	100	160	264	730	1680
Volume of materials needed for a 10 sq. m wall, in m3	1,0	1,6	2,6	7,3	16,8
Volume of materials needed for a 10 sq. m wall, in m3	124	161	382	2920	20160

How is PIR Premier different from other PIR systems? 

For more than three years our custom-made PIR Premier blend guarantees the quality of sandwich panels and PIR Plita® insulator: thermal conductivity and physical and mechanical characteristics. The reason is PIR Premier was created specifically for our lines. Whereas most manufacturers of sandwich panels with polyurethane use universal foam from a limited range of manufacturers.
