Exterior Twinroll Screen
ALWECO’s exterior twin roll screens are virtually identical to its standard twin roll screens. They provide the perfect alternative to traditional glass walls, except that they are assembled outside the greenhouse if it is not possible to install them inside. This does not affect the system’s effectiveness in any way and even has an additional advantage insofar that heat is kept out before it has even reached the greenhouse itself. When fully retracted, ALWECO’s exterior twin roll screen is also extremely compact.
