The crucial difference lies in the side guides. A zip screen (also known as a Ritsscreen®) has a unique zip system along the sides of the fabric, which is held in the guides. As a result, the fabric is fully enclosed and extremely wind-resistant (up to wind force 8).
A standard screen does not have this zip system, so the fabric can flap in strong winds and hangs less taut. For most situations in Limburg, our advisers at Renoco Sittard often recommend zip screens because of their durability and stability.
