Spray Foam Insulation – High-Performance Thermal Envelopeby Evergreen P. Evergreen Power UK, No.1 spray foam insulation
To build your home energy-efficient, it is important to lower energy loss with the help of a high-performance thermal envelope. Unlike fiberglass insulation, Spray foam insulation is a better choice when it comes down to picking the right insulation package for your home. It saves huge energy bills and cuts down on utility bills.
Several studies by the U.S. Department of Energy have reported air penetration through various openings causes a 40% loss in your home’s energy. The buildings that are having spray-on foam insulation offers 50% protection.
Spray foam insulation also protects your home through a thermal envelope.
The R-value refers to the heat flow to thermal resistance. The spray loft insulation product contains an exorbitant amount of R-value. The product becomes super-effective. The R-value may increase when the insulating material becomes thick. While measuring thermal resistance, the air infiltration and air exfiltration are not taken into consideration. Closed-cell foam insulation, polyurethane is one such closed-cell foam insulation product that has low-conductivity gas in its cells. As the product has high thermal resistance to gas, polyurethane insulation has an R-value of 5-6 per inch. Fiberglass insulation comprises an R-value of 2-4 per inch.
The Spray insulation foam has an important ability to make an air seal by developing a custom airtight envelope in the building structure. The benefit of air sealing is that it restricts the transfer of heat in the summer months and reverses in the winter months. Because the heat from the building cannot escape through the openings, as there is not enough movement of air.
Spray-on Foam insulation can block all heat transfer
Transfer of heat through conductive methods – When thermal energy from a substance flows from an upper region to a lower region.
Transferring of heat radiant methods – The other elements absorb the heat energy visible in the warm surfaces. This happens when these other surfaces emit low reflectivity.
Heat transfer through convective methods – The heat that develops somewhere else and supplied through various atmospheric means like air and water.
How does it work?
Spray insulation UK comprises two-part while spraying. One has two 55-gallon drums containing urethane material, and the other has water blowing agent.They mix these two chemicals in the spray nozzle and then it expands a hundred times when it is application mode. Naturally, it fills all the openings and spaces and creates a huge barrier for air to enter.
