User Review: Northwest Territory 15 x 15 Polyester Pentagon Screen House
Design: petagonal warm weather screen house
Ease of Setup: usual hassle, not hard or easy
Weight: no idea - it's very lightweight.
Price Paid: 60 bucks on sale
Funny, I bought this screen house a couple of years ago, and have had no problems with it. We have a very shady yard and I'm sure this is why we had no sun damage. If I set the screen house up in the sun, I would be sure to buy some kind of sunscreen spray, I know Scotchguard has one - to protect it from sun damage. Thing is that the sun is a potent oxidizer. I don't care what fabric you're talking about, unless it has some kind of protection, the sun is going to make it fall apart.
I even put it in the washing machine at the beginning of the season and it looks like new (well, almost.) If you do this, remember to take off all the metal fittings and cords.
