Abstract:
1. A method of attaching a daylighting sheet to a transparent glazing surface for receiving incident light, wherein the daylighting sheet comprises a base and a microstructure-defining surface opposite the base defining a series of light controlling microstructures selected from the group consisting of troughs, grooves, prisms, and posts further define a series of elevated points and troughs relative to the base, comprising the steps of: providing an optical adhesive for adhesively contacting substantially only selected elevated points, such that the selected elevated points of adhesive contact provide an optically transmissive adhesive for contacting the glazing such that troughs, grooves, prisms, and posts of the light controlling microstructures face the incident light; engaging the microstructure-defining surface directly against the glazing with an applied pressure, such that the adhesive effectively seals light controlling microstructures against the glazing surface.
