Insulation

Question 1

What are the three processes of heat transfer?

Answer 1

Convection

Radiation

Conduction

Question 2

When do you use cryogenic insulation?

Answer 2

For processes below -101°C

Question 3

When do you use thermal insulation?

Answer 3

For processes between -101°c and +815°C

Question 4

When do you use refractory insulation?

Answer 4

For processes above +815°C

Question 5

What temperature is absolute zero?

Answer 5

-273°C / -459°F

Question 6

What are three categories of thermal insulation?

Answer 6

Fibrous
Cellular
Granular

Question 7

What is temperature conductance?

C

Answer 7

Indicates the total rate of heat flow for the actual thickness of an insulating material

Question 8

What does a low C value stand for?

Answer 8

The lower the C value the better the insulation value is

Question 9

What is temperature conductivity?

K

Answer 9

Total rate of heat flow for a 1-inch section of insulation

Question 10

What does it mean if a material has a lower K value?

Answer 10

Lower K factors are better insulators

Question 11

What is temperature resistance?

R

Answer 11

The resistance to heat flow through a unit of area

Question 12

What does a higher R value show on a material?

Answer 12

The higher the R value, the more efficient the insulation

Question 13

What noise is permanent hearing damage possible at?

Answer 13

70 dBs

Question 14

What is cladding?

Answer 14

A protective cover for insulation

Question 15

What side do you pace the vapour barrier?

Answer 15

The warm side of the insulation to restrict the movement of moisture
