Dupont introduced a new insulating material that reflects heat in the summer and insulates in the winter. DuPont Tyvek ThermaWrap is breathable aluminum housewrap that prevents condensation and lasts for the lifetime of the building, according to Dupont.

Dupont is rolling out a line of sustainability-oriented products that it expects will add $2 billion per year in revenue. Obviously they believe that new construction is interested in paying extra for energy efficiency. The company's press release says its energy efficient products will cut CO2 emissions by 40 million tons (no idea over how many years).

Hopefully builders will quickly offer materials like this as standard options to commercial and residential buyers. Considering that the extra cost can be added to the mortgage and reduce the tax liability, investing in energy efficiency building materials is a no-brainer.
