1. What is Reddi-Wall?
Reddi-Wall is a polystyrene foam block similar in appearance to a cinder block. It is used in the construction of residential, commercial and industrial buildings.

2. Is Reddi-Wall as strong as a cement block or a poured wall?
With the truss type construction and rebar it is many times stronger than block or reinforced poured wall systems.

3. What material can be used to finish the exterior surface of a Reddi-Wall system?
Any surface treatment that is put on a conventional home can be placed on the exterior of the Reddi-Wall building.

4. What is the R value of Reddi-Wall?
The calculated R value of the wall empty is R 26. In actual infrared tests, the wall assembly has tested in excess of R 70. The average R value of an ICF wall is R 50, as testing has proven by a certified company.

5. What kind of performance record does Reddi-Wall have?
There are over 11,000,000 homes in Europe over 25 years old. In Michigan there are over 5000 structures with the Reddi-Wall system. There has never been a problem with the structure or water leakage.

6. How does using Reddi-Wall affect heating bills?
When used for basements only, heating bills are reduced by 50% or more. There is a 2600 square foot test home that is built entirely with Reddi-Wall blocks. The year (1998) average heating bill is $15.86 per month.

7. How are cooling bills affected when the basement is made with insulated foam? Doesn't the basement help cool the house?
In an actual test it was found that the air conditioning bills are much lower. The part of the basement above grade is only R 1. This lets in a lot of heat.

8. Are there any smells associated with the foam block?
No, it is odorless.

9. Is there any off gassing from the foam?
There is no off gassing. The foam has been given a food clearance.

10. Is the smoke toxic if a fire should occur?
The by products of combustion are CO2, CO and water. That could suffocate someone. It is nowhere as toxic as a burning sofa or carpet.

11. What is the temperature at which polypropylene melts?
The melting temperature is at 254* F. Some woods and most cloth materials will spontaneously burn at that temperature.

12. At what temperature will Reddi-Wall block flash into flames?
At 650-700* F. The block has a 2 Hour Fire Rating -Flame Spread 15 -Smoke Developed 125.
