Advantages of using Fiberglass (FRP) Ceiling Domes

• Fiber­glass ceil­ing Domes are used wher­ev­er light, strong, weath­er resis­tant struc­ture are required.
• Archi­tec­tur­al FRP domes resist rot, rust, water,chemical and flame, FRP Domes also are hur­ri­cane and earth­quake resistant.
• Fiber­glass dome can be fin­ished to repli­cate any oth­er build­ing mate­r­i­al like gold, cop­per, ter­ra cora, mar­ble, gran­ite and stone.
• Finals can be added to the top of the FRP Ceil­ing Dome, these finals can be pin­na­cles, cross­es, urns cupo­las and towers.
• Fiber­glass Domes are easy to install and require very low maintenance.
• Petra design’s FRP Domes con­sist of pie shaped sec­tions that bolt togeth­er at the job site. After the FRP dome is assem­bled it can be lift­ed with a crane as one unit. When placed on the build­ing struc­ture it only needs to be bolt­ed down to the structure.
• Inte­ri­or Ceil­ing Domes can also be man­u­fac­tured and incor­po­rat­ed with Exte­ri­or Domes, by hav­ing inte­ri­or dome and Exte­ri­or Dome This allows for insu­la­tion of the cav­i­ty between the inte­ri­or and the Exte­ri­or Ceil­ing Dome shells.
