The new horizontal caterpillar insect screen will certainly amaze you as even when closed it lets you enjoy the Thèa (view in Greek), from the interior of your house. Once more Japanese technology has come forth with Thèa, a new proposal with a unique design. The maximum opening width can reach 1,8m and the height can reach 2,6m. The fabric's material is polypropylene. The bottom silicone rollers give an improved scrolling on the bottom rail (since there is no bottom guide). One of the most innovative characteristics of this product is the ability to adjust the spring, even after the installation is finished without disassembling the product!
