Spray Foam Insulation in Lawrence, KS

Spray Foam Insulation in Lawrence spans a wide range of houses. Neighborhoods closest to downtown, including Old West Lawrence, North Lawrence, East Lawrence, Oread, Hancock and Pinkney, hold older homes, and several are on the National Register of Historic Places. West of Iowa Street, neighborhoods such as Sunset Hills, Prairie Meadows, Deerfield and Alvamar are newer. The 2020 census counted 94,934 residents and 43,421 housing units, 8.6% vacant.

Historic homes

Most of Lawrence was burned in Quantrill's 1863 raid and rebuilt afterward. Homes from that era and the decades after usually need dense-pack walls, sealed attics with blocked balloon-frame tops, and closed-cell foam on the rim and foundation. Interior work leaves historic exteriors untouched.

Rentals near KU

The University of Kansas is the city's largest employer, with 10,116 employees as of 2020, and many houses near campus are rentals. Sealing and blowing the attic and foaming the rim are cost-effective upgrades tenants feel.

Newer west-side homes

Newer homes need targeted work: rims, bonus rooms, recessed lights and attics built to minimum depth.

The code here
