Insulation Material	Price/Sq Ft.	R-Value/Inch	Green? (Environmentally Friendly)	Flammable?	Notes:
Fibreglass	$	R-3.1	Yes	No	Does not absorb water.
Mineral Wool	$$	R-3.1	Yes	No	Does not melt or support combustion.
Cellulose	$$	R-3.7	Yes	Yes	Contains the highest amount of recycled content.
Polyurethane Foam	$$$	R-6.3	No	Yes	Makes a great sound insulator.
Polystyrene (EPS)	$	R-4	No	Yes	Difficult to use around imperfections, can be come costly.

What are the performance terms and what do they mean?

Thermal Conductivity

Thermal conductivity measures the ease with which heat can travel through a material by conduction.

Thermal Resistance (R)

Thermal Resistance is a figure that connects the Thermal Conductivity of a material to its Width.

Specific Heat Capacity

The Specific Heat Capacity of a material is the amount of heat needed to raise the temperature of 1kg of the material by 1K

Density

The density refers to the mass (or ‘weight’) per unit volume of a material.

Thermal Diffusivity

Thermal Diffusivity measures the ability of a material to conduct thermal energy relative to its ability to store thermal energy.
