Insulating Homes in West Palm Beach
Spray Foam Insulation in West Palm Beach starts with the climate. The city's 1991-2020 normals list a July average high of 90.0F and a July average low of 76.1F, about 61.75 inches of rain a year, and a record high of 101F. Wikipedia classifies the climate as tropical rainforest, with a hot, humid wet season from May through October. Air conditioning runs most of the year, which makes attic heat and air leaks the biggest targets.
A city with history
West Palm Beach was incorporated as a town on November 5, 1894, and as a city on July 21, 1903, two years before Miami, and it became the county seat in 1909. It has at least 13 locally designated historic districts, including Old Northwood, Flamingo Park and El Cid; most Flamingo Park homes were built from 1921 to 1930. ACS data via Point2Homes shows 8.7% of housing from 1939 or earlier and 24% from 2000 to 2009.
Historic homes
Mediterranean Revival and Mission-style houses from the 1920s often have low-slope or flat roof sections, cathedral ceilings and attics too small to work in. Closed-cell foam fits shallow spaces; where attics are accessible, sealing and blown-in work well. In historic districts we avoid anything that changes the exterior.
Newer homes
Homes from the 2000s usually have more insulation but often have leaky duct connections and gaps at the air handler. A sealed attic or a sealed ceiling with more blown-in are the two paths, and we price both.
Flood maps
New FEMA flood zone maps took effect December 20, 2024, affecting more than 1,000 properties in the city. Flooding does not change attic insulation targets, but homes that took on water may have wet wall insulation that needs replacing.
