Birkdale Perfect Fit® is a totally unique product that allows a variety of blind types to be fitted to double glazed windows and doors without the need to drill or screw into frames or surrounding plaster work. With Perfect Fit™ the frames are made to fit the windows/doors and the blinds are made to fit the frames and they all fit perfectly. Blinds using Perfect Fit™ are able to operate with the window allowing the ideal combination of shade and ventilation regardless of the window type. Perfect Fit™ blinds are particularly suitable for use with conservatory or atrium installations where multiple glazing units are used in tandem with each other. Perfect Fit™ blinds can be manufactured to fit even those awkward shapes found in conservatory roofs - and all of this without any need for drilling or screwing into your structure or plaster work. Perfect Fit™ blinds come in a variety of frame colours to compliment all types and makes of double glazed systems perfectly.
