Cellular Perfect Fit Blinds offers a range of benefits including keeping the heat in during winter and providing a cooler living space in the summer. Cellular fabrics are slightly different to Pleated fabrics, they are a honeycomb effect, meaning you can not see any visible cords due to them being hidden between two pleats giving the blind a neater look. The most important aspect to Perfect Fit Blinds is the way they fit, simply slide the bracket into the rubber beading. No holes, no drilling and no screws!
