Insulation

Basics

• The use of materials to prevent the passage/spread/leakage of heat
• Can improve efficiency
• Can allow for ulra low/ultra high temperatures

Common Materials

Fiberglass

• Sleeve, 1/2" I'd, 1/4 wall -[1]
• 1/4" ID, 9/32 wall - [2]

Aramid

• Fabric made of synthetic fibers roughly similar to nylon
• 1/4 I'd, 1/16 wall - [3]

Foamed Plastic

• Polyurethane Spray foams etc
• Easy to apply
• Fills cracks well
• Hard to remove

Aerogel

• Essentially a jell with the liquid being replaced with a gas
• VERY insulating
• Can be complex to make depending on type + materials etc

Vacuum Panel

• Aerogel but with a vacuum instead of a gas
• The bes insulator, but insulation degrades due to gas intrusion
