Sunpeak Construction Company contracted with Illig Construction Company to work on the Holy Trinity Catholic Church, owned by Diocese of Orange, located in Ladera Ranch. This beautiful church is located next to residential development, required special sound attenuation, and was designed by Lundstrom & Associates which featured an Italian Tuscan look with heavy steel structure. The overall project included a Chapel, Sanctuary, Baptismal, Sacristy, Narthex, meeting rooms, facilities, storage, and a 60-feet Tall Bell Tower.

Sunpeak Construction Team performed Metal Stud Framing, welded all-steel backings needed for wall-mounted fixtures, installed 2 layers of Exterior Dense Glass with a 2-Inch thermal and sound Rigid Insulation Styrofoam by Dow between the layers attached with Stainless Steel Screws, installed 2 layers Interior Fire-Rated Mold & Mildew Resistance Hi-Impact Type XP Gypsum Board / Gold Bond manufactured by National Gypsum, with top quality level 5 Smooth Finish or Putty Coat, installed all the Sure-Board manufactured by Cemco, to provide shear value on the walls with large openings for windows & doors, performed all rough carpentry work and used special Simpson Strong-Tie Hardware and installed roof sheathing with Fire-Treated Plywood and performed all lath & plaster in Historical Smooth Steel Trowel Finish. In order to obtain a very smooth & clean surface and mitigate cracks, Sunpeak installed Structa Mega Lath and XJ Control Joints / Expansion joints by Clark Dietrich throughout and applied Omega Crack Isolation system on the Brown Coat before application of final coat.

The special construction of exterior walls consisting of 2 layers on interior drywall, 2 layers of exterior Dense Glass, 2” Rigid Insulation and 7/8” lath & Plaster along with GFRC veneers at certain locations created a heavy-duty barrier for noise transfer which made this beautiful church located next to residential development pretty much sound-proof while the church would be in session and of course a very good thermal barrier for heat transfer that made it very energy efficient and a Green Building. To expedite the construction schedule and cut down on cure time, Sunpeak Taping crew used 20-Minute, 40-Minute, and 90-Minute Fast Set Lite or hot mud manufactured by Westpac for the interior work and used Omega Diamond Wall PM System for exterior plastering.
