The Ventura tab panels are woven in a unique way that has beautiful slubs of linen woven throughout the base cloth. This weaving technique gives the panels a lightly speckled effect increasing the surface texture of the fabric. These are then bonded with a flocked rayon backing which makes them impervious to light penetration, repel summers heat, defends against winter's cold and effectively dampens sound from outside sources. These Thermaplus panels are our premium grouping from fashion to efficiency and comply with all condominium regulations. These panels are sold in pairs each panel measuring 78"" wide, finished with twelve tabs per panel each measuring 2""W x 3""L inches and can accept up to a 1.25 inch decorative curtain rod to complete the look. These extra wide panels are great for double doors or wider windows.
