Polycarbonate Store

05/26/2026

This DIY greenhouse build in Olympia, WA is a great example of using the right materials for a wet climate.

The structure was built with milled lumber from their own backyard fir tree, paired with repurposed windows for the sidewalls. For the greenhouse roof, they needed something that looked good, installed clean, and could handle rainy conditions.

They landed on twinwall polycarbonate panels.

Polycarbonate is a strong choice for greenhouse roofing in the Pacific Northwest. It’s lightweight, durable, and handles moisture well when paired with the right sealing components.

With help from our team, they put together a setup that fit the build and made installation straightforward.

Materials used:
• 6mm Twinwall Polycarbonate Sheets
• Joiner Cap
• End Cap
• Foam Glazing Tape
• Gasket Washers
• Washer Head Screws
• Sikasil-N Plus Silicone Sealant

From first panel to final screw, this one came together right.

Built with our 8mm twinwall polycarbonate, capping, and install accessories for a tight, durable setup that’s ready for the long haul.

“I really appreciate all of your help and patience as I worked through this process. Your products are great and so was your support.”

Good materials matter. So does having the right support behind them.

This customer built their own cedar greenhouse using our polycarbonate materials and sealing components and the results speak for themselves.

"We are so happy!! The other morning when the temperature dipped to just 32 degrees, the inside of our greenhouse was still a balmy 67 degrees with no supplemental heating!"

That kind of performance comes down to panel choice, proper sealing, and how everything is put together.

Materials used:
• 16mm Triple Wall Polycarbonate Sheets
• 16mm 5X-Wall Storm Sheets
• Polycarbonate End Cap (U Channel)
• Brown Aluminum Bar Cap
• 16mm Aluminum U Channels (special request)
• Vented Polycarbonate Tape
• Foam Glazing Tape
• Sikasil-N Plus Silicone Sealant
• Gasket Washers
• Washer Head Screws
• Zinc Plated Pan Head Screws

Built for Maine winters. Still going strong.

Jacquesinthegarden of Epic Gardening built this 12x16 DIY greenhouse using polycarbonate for one big reason: flexibility. Easy to cut, easy to customize, and built to handle real conditions.

16mm triplewall on the roof for snow load. 10mm on the sides. Buried in snow outside, warm and usable inside.

That’s the difference when you build it right.

If polycarbonate shipping caught you off guard, you’re not the only one.

There’s a lot happening behind the scenes with freight, crating, and delivery, and crate size is what really drives the cost.

The good news is, with a little planning upfront, you’ve got solid ways to keep it manageable.
