Simple measures such as sealing air leaks and caulking around windows and doors can provide a faster payback and a better return on investment for limited budgets. Ultimately, the best strategy is to prioritize the measures that provide the most cost-effective energy savings and the quickest payback period.
Tables of Building Material R-values The R-values for specific assemblies like doors and glazing in the table below are generalizations because they can vary significantly based on special materials that the manufacturer uses. For instance, using argon gas in a double pane insulating glass unit will dramatically improve the R-value. Read more…
Copper has been the mainstay of plumbing supply systems for decades. While the system is very popular it is particularly susceptible to freezing. Copper plumbing is rigid and does not stretch when ice forms. Water expands approximately 9% when it freezes. Plastic plumbing systems have some stretch to them and Read more…
