Perfect fit Pleated blinds offer ultimate light control and can be operated as a top down as well as a bottom up blind, providing ultimate privacy and light control. They offer a 32% reduction in heat loss, by combining the honeycomb structure with the perfect fit frame, these blinds eliminate the gaps around the edge of the fabric and have been shown to perform better than free hanging options. The perfect fit system allows you to fit the blind without the need for drilling or screwing into your UPVC window, so you won’t invalidate the warranty on your windows like you would with other systems. What’s more, all tension cords are enclosed within the system and is child safe by design. This is not a total blackout product, so you will get some light leakage at the edge of the Perfect Fit Frame.
