What our customers are saying

  • "My greenhouse has held up extremely well after four winters of snow and with annual cleaning looks as good as the day it was built. Our only complaint is that we didn’t build a bigger greenhouse."

  • "Thanks for all the help and ease of ordering the 16mm TripleWall Polycarbonate."

  • "I appreciate your ability to cut the polycarbonate accurately, it made the assembly easy and I probably would have destroyed a piece if I cut it myself."
