A framing system suitable for the assembly of thin panels such as glass or acrylic, which might be used in the construction of greenhouses, sun rooms, pool enclosures, wind screens or other non-insulating applications. The framing system consists of a unique three piece design which makes it particularly suitable for application to plastic materials such as ABS or PVC. The three piece design consists of an main supporting beam with a toothed slot to accept a correspondingly toothed extension of a T-shaped cover strip. The cover strip acts only to retain the supported panel against the beam. The beam supports the entire weight of the panelling. The beam is grooved along its edge in order to mate with a correspondingly shaped connector block. The connector block serves to connect adjacent beams.
