INSULATION

THE FIRST INSULATION

• Mud was used as one of the first insulators
• Straw was also a popular insulator
• During the 1800's insulation was most commonly straw and horse hair

INSULATION R-VALUES

• R-Value is a measure of insulation’s ability to resist heat traveling through it.
• Colder regions require thicker insulation. Therefore the thicker the
• Insulation the higher the r-value.

TYPES OF INSULATION

BATTS AND ROLLS

FIBERGLASS INSULATION

• Applicable on unfinished walls, including foundation walls.
• Insulation methods, between studs, joists and beams
• Inexpensive

MINERAL WOOL INSULATION

• Can be installed like fiber glass insulation
• Relatively in expensive, 30$ a roll

CONCRETE BLOCK INSULATION

CONCRETE BLOCK INSULATION

• Materials:
• Foam board, to be placed on outside of wall
• Where applicable:
• Unfinished walls, including foundation walls
