What is Corrugated PVC? 

PVC corrugated sheeting is a widely available, economical option made from the popular plastic resin Polyvinyl Chloride. This includes products like the PVC Corrapol Clear Roofing Sheet. It is commonly used in construction products such as guttering and decking and offers a moderate lifespan.

The blue hue of PVC clear corrugated roofing sheets is a result of the manufacturing process. Despite their reputation for cracking, PVC sheets are still a viable option. 

Many PVC corrugated sheets on the market are infamous for yellowing fast and cracking and splitting from the brittleness of the sheet. Although a cheaper sheet at first may seem more appealing, most PVC sheets are only UV resistant which means no coating only a slight resistance to slow the degradation. 

So the main takeaway is to buy your PVC sheets from a well known manufacturer, rather than own brand PVC sheet.

What is Corrapol Stormproof?

Dry Verge & Roofline Direct offer the Corrapol® Stormproof sheets, which are exclusively manufactured by Clear Amber. Their unique composition and unparalleled strength defy all stereotypes about clear corrugated sheeting, offering exceptional endurance and longevity at an affordable price-  the unmatched benefits of a Corrapol® Stormproof Corrugated sheet, including high clarity, proper UV protection, longer lengths, and exceptional robustness.


Constructed using a virtually unbreakable resin, our stormproof sheets are the strongest choice for corrugated roofs. Their exceptional strength provides superior impact resistance, making them ideal for outdoor structures such as Lean-tos, carports, pergolas & much more.

When compared to PVC corrugated sheets, which are lighter and have a lower impact resistance, there is no denying the unmatched strength and strength is crucial in ensuring your roof withstands harsh weather conditions. Stormproof sheets live up to their name by providing unparalleled wind uplift and crack resistance. Don't settle for a standard PVC sheet from a DIY store that will easily succumb to even the slightest storm. Upgrade to the durability and reliability of Corrapol Stormproof sheets.


Installing a Stormproof clear corrugated sheet means choosing unmatched clarity that will last. This incredible clarity comes from the top-quality resin used in the manufacturing process. While other "clear" sheets may have a cloudy or tinted appearance, Corrapol® Stormproof remains truly transparent. This is important for larger projects where the cloudiness or tint can create a dull look and reduce light transmission. This is just one reason why homeowners are turning to Corrapol® Stormproof instead of traditional PVC corrugated sheets.

UV Protection:

Many installers may shy away from learning about 'UV Protection', but this concept is crucial for a roof's longevity and should not be overlooked. All clear materials are susceptible to UV damage, which can cause brittleness or yellowing over time as the sun's rays pass through. However, each type of plastic reacts differently to these rays, and some are even coated with a special layer to minimize the effects of UV. To ensure the longest possible lifespan, it's best to choose a Stormproof corrugated plastic sheet with a full UV protection coating. This will prevent the sheet from becoming brittle or discolored, unlike PVC sheets which tend to do so quickly.


The estimated lifespan of corrugated PVC sheets is approximately 5 years; however, this may vary depending on the level of sun exposure and potential weather conditions. The Corrapol Stormproof sheets, which offer superior strength and UV protection, have an impressive estimated lifespan of over 20 years. With their exceptional clarity and durability, these roofing sheets are suitable for various applications, including canopies, shelters, and covered walkways. While they may be slightly more expensive than traditional PVC sheets, the long-term benefits and return on investment make Corrapol Stormproof sheets a worthwhile and cost-effective option.


Do-it-yourselfers can easily install all types of corrugated sheets with their simple and efficient overlapping fitting method. By using corrugated roof fixings, a secure waterproof cover is ensured. The patented Rock N Lock® flashings, compatible with both PVC and Stormproof sheets from the Corrapol® range, are crucial in protecting against wind lift and securing the fixings at the gables. One of the main advantages of the Stormproof sheets is their strength, making them easier to cut and drill than traditional PVC sheets that may crack if not handled properly. This means that you can handle the product with confidence, knowing that you won't damage the sheets before they are installed and put to use. Additionally, the strong nature of the Stormproof sheets allows for lengths up to 4000mm, reducing or eliminating overlaps on longer roofs and minimizing the risk of leaks. Choose Corrapol Stormproof for a secure and durable roofing solution.
