How to Build Structures Using GCT’s Panels

The wall panel can be easily handled by one or two people, helping the team to speed up the construction.

Plumbing and electrical piping installation 

  • Before placing the concrete or mortar on the panel surface, install all plumbing and electrical piping. 
  • Heat guns can be used to create the chases in the EPS prior to placing the electrical, communications and plumbing conduits. 
    • If rigid conduits are required, the steel metal mesh can be trimmed with normal steel cutting shears and afterwards replaced with portions of steel reinforced mesh.
    • The insulation and steel wire can be easily cut to allow concealed placement of all utility.

Once the panels have been correctly positioned and the electrical and plumbing is in place, Structural mortar is applied to the panel surface on both sides up to three quarter (3/4) inches over the wire mesh. 

For optimal panel performance, use a coat of structural mortar of three quarter (3/4) inch thickness over the wire mesh on both sides. For finishes, use a thin coat of Type N or Type S mortar. 

The installation of the panels works great with our mortar application machines for an efficient construction project. 

Applicable Codes and Standards

GCT Structural Panels meet IBC/IRC Building codes and have the Florida Product Approval (FPA). For additional code compliance, please refer to the Section 2 in page 2 of the Carmelo Panel’s TER.

Zoning Codes and R-Value Requirements

Our Panels meet Zone 1 codes for thermal insulation as well as other Zone requirements across all US states. They also meet the R-Value Requirements in accordance with the PRECC for walls and roofs*: 

  • According to the International Energy Conservation Code (IECC) some of our panels meet the ideal R-Value of 30 for roofs, necessary for Part of Climate Zones 1. 
  • The Puerto Rico Energy Conservation Code establishes that we are Zone 1 and in the region of Tropical Sun requires that roofs need to have a minimum insulation R-Value of 15 to follow the codes. 
  • In Chapter 4 on residential energy efficiency, section R401.2.1 on Tropical Sun in point number 6 it speaks about the R-Value of 15 for the roofs which should meet the requirements in table 402.3 and 402.1.1. 
  • Our Roof Panels meet these R-value requirements and have the capacity to reach R Values up to 36 as confirmed in our TER (Table 15 in page 23 ). This provides optimal insulation and cooling for homes, helping with residential energy efficiency.
