Spray Foam Insulation
in Princeton, TX

Princeton has grown rapidly over the past decade as homebuyers have looked east along US-380 for more affordable lots in Collin County. Communities like Bluebonnet Farms, Kreymer Estates, and the developments along the Lavon Lake corridor have brought thousands of new homes to Princeton in a short window. The vast majority of this housing stock is less than ten years old, built by production builders to the Collin County inspection standard. Code minimum insulation in these homes means R-20 to R-30 attic insulation — adequate for a certificate of occupancy, not adequate for a Collin County summer.

New Construction Does Not Mean Optimal Insulation

The most common misconception we encounter in Princeton is that new homes are well-insulated. They are insulated to pass inspection — that is a different standard. A home built in Kreymer Estates in 2021 has exactly the insulation the builder needed to install to get the final sign-off. On a 2,400-square-foot Princeton home sitting on an open lot with minimal shade, the gap between code-minimum fiberglass and a properly air-sealed attic shows up clearly in the first full summer. The HVAC runs long cycles, the second floor sits warmer than the first, and the bills are higher than the builder's energy estimates suggested.

Open Lots and Full Sun Exposure

Princeton's newer communities are built on land that was agricultural a decade ago. Tree canopy is minimal — it takes 10 to 15 years for planted trees to provide meaningful shade on a roof. In the meantime, a Princeton attic in July is absorbing direct sun for six or more hours a day with nothing to break it. Attic temperatures in these homes regularly exceed 145 degrees on peak summer afternoons. Spray foam applied to the roof deck creates an airtight seal at the source, reducing attic temperatures by 40 to 60 degrees and dramatically reducing the heat load on the HVAC system.
