Prior Canopies Supported Carports use polycarbonate sheets as the roof glazing material, not corrugated plastic. What is the difference?
Basically our polycarbonate roof glazing sheets are multi-wall, super strong, with a beautiful smooth finish. Corrugated plastic sheets are thin, “wavy”, sheets of clear or opaque plastic, which can be brittle and allow dirt to gather in the valleys.
The difference between the strength of the two products can be illustrated by a true story. My carport, with polycarbonate glazing, has been fitted for 3 or 4 years. My neighbour had a carport fitted 6 weeks ago, using corrugated sheeting. Two weeks ago, on 28th June, there was a freak hailstorm at home (Hinckley, Leicestershire). Massive damage was done to properties and cars. Luckily my car was at work, 40 miles away. On checking the damage that weekend I noticed some broken roof tiles and broken branches. My carport was completely in tact, not a mark on it. However, when I checked my neighbour’s carport, I could hardly believe the damage. There were literally more holes than roof – it was completely destroyed! Both of our carports are on the west side of the house and the houses are the same size. My neighbour now has to claim on his house insurance, which will no doubt result in increased premiums in the future. By trying to save himself a few quid he has caused himself a lot of hassle and extra expense.
Remember – buying cheap doesn’t always save money.
