1. How does heat move?
Heat moves through one of three basic methods:
- Conduction is the energy transfer through solids. Different types of solids transfer heat more easily than others, with metals among the most conductive and ceramics among the least conductive.
- Convection is energy transfer through gasses or liquids. Currents carry heat energy through the liquid or gas. Most heat energy is transferred through convection.
- Radiation is energy transferred through electromagnetic waves. Radiative energy converts to convection when it touches a solid surface.
2. Where is heat attracted?
As a simple rule, heat always follows cold. Just like water, heat will move through the path of least resistance until it reaches a state of equilibrium.
3. What is R-value?
An R-value is a measure of how well a convectional insulation resists heat transfer through conduction only. It was developed to test the insulating properties of traditional insulation and ignores heat transfer by radiation and convection. It measures only “conductive heat transfer” – how much and how fast it absorbs heat and transfers it through a specific insulation.
4. Is there a downside to R-value testing?
Yes. R-values are measured in a controlled environment and does not measure insulation against convective or radiational heat transfer. Real world situations can compromise the R-value of traditional insulation substantially. For example, traditional insulation can lose 35% of its R-value when as little as 1.5% humidity is introduced.
5. How does conventional insulation work?
Traditional insulation, including fiberglass, cellulose, polyurethane foam and other solids, contain small pockets of air that slow conductive heat transfer. They do not block or prevent the transfer of heat. Traditional insulation only slows the conductive heat transfer. However, heat will be absored, will load, and will transfer.
6. How can ceramic coatings help me?
Ceramic coatings effectively lower temperatures inside of buildings, leading to reduced energy costs and less heat stress. Super Therm® blocks heat load, moisture penetration, and air filtration.
7. When should I use Super Therm®?
Super Therm® can be used as replacement for traditional insulation on most substrates and in most conditions. Super Therm® is extremely effective because it reduces moisture load into a substrate and air infiltration through a wall cavity, which substantially increases its insulation value over traditional insulation. Super Therm® will prevent moisture load, seal surfaces and cracks, which reduces air flow as well as blocking heat transfer.
