Kinzler Installs Gypsum Concrete and Insulation for Attivo Trail

Kinzler Construction Services completes multiple phases of Attivo Trail property for Haverkamp Construction.

Haverkamp Group has built many of its properties in central and eastern Iowa with its on-site construction company, Haverkamp Construction. One of their ongoing projects that Kinzler Construction Services was hired for was their Attivo Trail property located in Ankeny, Iowa. As part of the first phase, Kinzler completed gypsum concrete pre-pours underneath tubs and open chases, which ensures continuous coverage across the entire floor to pass the fire code. Once the drywall and painting are complete, we come back and pour the entire floor. Gypsum concrete is a lightweight material used for sound reduction, and fire ratings and can also be used for radiant heating and some floor leveling projects.

On the project, we were also contracted to install all the insulation in the building. This includes spray foam, fiberglass batt insulation, and blown-in. After air sealing the exterior cavities, we insulate them with R21 batts. Ensuring all six points of contact for a continuous R-value across the whole wall system. Afterward, we put on 6mil poly that acts as a vapor barrier. The corridor and partition walls were insulated with R19 batts to meet the fire code and separate sounds from other units and the hallway.

Open cell spray foam of 5-6 inches was applied in box sills and rim joists between the floor systems and the roof. A strong R-value here helps eliminate air penetration in the floor assemblies where waterlines could freeze if not insulated properly. Lastly, an air-breathable netting is stapled onto the ceiling before blowing the entire floor assembly with fiberglass insulation to help eliminate sound travel between the floors of each unit and to meet the fire code.
