A homeowner on 9th Street in Dallas, TX, just a short drive from downtown and the Bishop Arts District, had a bigger plan for his basement. He wanted to expand it into an office ADU, with a quiet, comfortable space to work without leaving home. Before he put up any drywall, he knew the walls needed proper insulation or the room would never feel right in a Texas summer.
He called Dallas Spray Foam Insulation, and our team sprayed open cell foam into the framed wall cavities, filling every stud bay and sealing the gaps around the framing. With the walls insulated, the basement is ready for finishing, and his future office will stay comfortable and quiet.

A homeowner on Doyle Avenue in Dallas, TX, not far from the Dallas Zoo, liked spending his free time in his garage, but the Texas heat made every project a slog. By midafternoon the air under the roof felt like an oven, and the tiredness it brought out meant he kept putting off the jobs he meant to finish. He decided the garage needed to stop working against him.
He called Dallas Spray Foam Insulation, and our team sprayed closed cell foam over the roof deck and between the framing, covering the foil-faced surfaces that were not stopping the heat. Now the garage stays cooler, and he can start a project in the afternoon instead of waiting for evening to get anything done.

A business owner who had just rented a commercial space on Perimeter Drive in Dallas, TX, was already thinking about summer. His crew would be working inside all day, and the goods he sells could not sit in a hot building. Delivery trucks coming in along Interstate 30 would unload straight into that heat, and bare metal walls and a metal roof only make it worse.
He called Dallas Spray Foam Insulation before he moved his stock in. Our team sprayed foam across the metal wall panels and up into the roof section, sealing the gaps along the posts and trusses. The building now holds a steadier temperature, so his employees can work comfortably and his products stay protected through the hottest months.

AFTER
A homeowner on Buckner Terrace in Dallas, TX, had a home office right below his son’s bedroom. His son plays music, and he never played it loudly, but with Dallas summers keeping every window shut and the AC running all day, even a quiet guitar or keyboard carried through the ceiling. The homeowner wanted fewer interruptions while he worked, without asking his son to stop playing.
He called Dallas Spray Foam Insulation, and our team sprayed foam across the office ceiling, covering the surface and the gaps around the conduit and light fixtures. The sound coming down from the bedroom dropped noticeably, so the father can focus on his work, and his son can keep playing.
