San Francisco Energy Efficiency Requirements of
Insulation for New Homes Explained
Are you building a new home in San Francisco and
struggling to work out the requirements for insulation?
Find the answers to your questions in USA Spray Me's
guide!
In the guide, you'll find a
breakdown of fiberglass and
spray foam insulation and which
one aligns best with the new
building codes in San Francisco.
San Francisco’s building codes are part of the California Title 24 Building Energy Efficiency
Standards, which are put in place to reduce the environmental impact of new homes.
One of the measures for energy efficiency is the U-
factor, with lower values indicating better insulation
performance.
For walls, the minimum R-value for external insulation is
R-3.5 or a combined R-16 for internal and external
insulation and at least R-30 to R-38 for roofs and
ceilings.
USA Spray Me uses polyurethane foam, a safe material that makes it easy to comply with Title 24
regulations, which will be updated on the 1st of January 2025.
