Description of Work:

Reglaze Greenhouse in 16mm Triple wall Polycarbonate. The project includes removal and disposal of existing greenhouse material, clean-up and reinstallation of “like” glazing 16mm triple wall polycarbonate in matching thickness. Project estimated sizing is 47,600 sq.ft of surface area.

Project Includes:
  • Complete reglaze of all greenhouse buildings
  • Re-use Existing Aluminum glazing bars and fasteners (replace as needed)
  • New poly tape and caulking/sealant included
  • Reglazing to be done in coordination with greenhouse manager in order to maintain crop bio security
    • Each room needs to be clear of plants before removing polycarbonate
    • Each room will be fully sealed and reglazed before moving to adjacent rooms
  • Polycarbonate Notes:
    • 16mm, Clear
    • Sidewalls: ~235 Sheets 48” W x +/- 6’ L (includes 2’ tall side vent)
    • Gable Walls: 9 ½ gable walls to be fully reglazed
    • North side gable walls: 5 partial gable walls to be fully reglazed
    • Roof: Complete roof reglaze on all houses ~ 420 sheets 48” W x 21’L (includes roof vent area), ~ 29,500 sq.ft. of surface area
Not Included in Price:
  • Dumpster rental
  • Interior Partition walls to remain as is

Cost of Project (includes Materials and Installation): $257,448.00
Taxes: TBC
Freight of Materials: Included
TOTAL COST: TBD

Inspection Report:

We estimate 90% of the west side roof is damaged. One puncture could easily be missed if not examined closely. Our recommendation is to replace the entire glazing on all houses. This ensures that no damaged sheets are missed and the bio security of the research is not compromised.

Furthermore, the light transmission will not be consistent with different aged materials throughout. 16mm triple-wall polycarbonate panels naturally lose light transmission efficiency over time due to UV exposure, oxidation, and surface weathering. Installing new panels adjacent to aged existing material will create measurable differences in light transmission, light diffusion, and solar heat gain across the greenhouse envelope.

Because this facility is used for university research and controlled crop production, maintaining uniform environmental conditions is critical. Mixed aged and new glazing materials may negatively impact crop uniformity, growth rates, and the reliability of research outcomes. For these reasons, complete polycarbonate replacement is recommended rather than partial panel replacement.

Puncture in roof panel. Can be found on nearly all west side roof sheets, with several damaged gable wall panels.

Damage in several side vent panels on west side. Aged acrylic sheets show the light degradation and sustained considerably more damage.
