Hello Chris,
Dolphin Insulation hit it out of the park on this complicated attic retrofit. In terms of both specifying the retrofit measures and installation of materials, the quality of work was exceptional. It is common for installers to have difficulty in connecting the dots in difficult to access areas, but not the Dolphin crew, the thermal and air boundaries on this job were continuous in all areas and without a single quality issue. Well done, you folks really make our cellulose look good.
