Q. What is Polyisocyanurate Foam?
 
Polyisocyanurate foam is a rigid board insulation material composed of a uniform closed cell, Polyisocyanurate foam core bonded on each side to impermeable trilaminate foil facers.  Polyisocyanurate is now produced with a non-CFC and non-HCFC blowing agent, meeting the latest environmental regulations for using chemicals that do not harm the protective ozone layer in the earth’s atmosphere.  The new formula enhances the positive environmental profile for this energy saving product.
    
Laboratory and field testing data suggest that the stabilized R-value of rigid foam with this metal foil facing remains unchanged after 10 years.  Panels with foil facings also have higher stabilized R-values of 7.1 to 8.7 per inch.
 
Q. What is an R-Value?
 
Insulation is rated in terms of thermal resistance, called R-value, which indicates the resistance to heat flow.  The higher the R-value, the greater the insulating effectiveness.  The R-value of thermal insulation depends on the type of material, its thickness, and its density. 
 
Q. How  do you Measure a Box?
 
Measuring a box is as easy as 1-2-3.



Simply measure the length, width, and height of what you would like to pack and express the measurements.  Make sure to give the measurements in this order:

1.  Length
2.  Width
3.  Height

Allow a minimum of 1/8” extra to each dimension for the fitting.  Be sure that the length and width do correspond to the opening of the box.

Q. What size Insulated Box do I need?
 
Measure your product by length, by width and by height.  Allow some additional space for refrigerant packs (coolants) or wet ice or dry ice.
Keep in mind the ideal location of refrigerant in packing is on top or around your product.  Once you have determined this space you have your inside cavity space.  To that space you will add 2 times the thickness of insulation to each dimension.

Example:

You have determined your inside cavity required is – 9” x 9” x 9”.
Your temperature specifications require 1-1/2” insulation.
Add ( 2 x 1-1/2”) or 3” to each dimension……..
(Add 3” to the length, add 3” to the width, add 3” to the height)
Insulated Box Size Required:  12” x 12’’ x 12”
 
Q. How do you determine what type of refrigerant and what thickness of insulation you need?
 
These are determined by:

1.  What temperature you need your product to maintain.
2.  How long your product needs to maintain that temperature
3.  What type of transportation will be used for shipping.
 
Q. What is a refrigerant?
 
Refrigerants are products designed to control the internal temperature of a package.  There are typically only three temperature ranges refrigerants can maintain:  frozen, refrigerated, and warm.  The temperature requirements of your perishable product will determine the type of refrigerant you need to use.   Some common type of refrigerants  are refrigerant packs (gel, foam), wet ice or dry ice.
