A frame assembly for sheet material. A plurality of inner frame sections have at least one recess for receiving the sheet material. The inner frame sections can be fitted around at least part of the periphery of the sheet material. A first outer frame for receiving the sheet material with the inner frame sections fitted thereon is provided, together with a second outer frame to be applied to the sheet material with the inner frame sections fitted thereon. A mechanism to connect the first and second external frames together is provided, with the inner frame sections therebetween. The first and second outer frames together define a space whose shape corresponds to that of the outer cross-sectional shape of the inner frame sections. Thus, the first and second outer frames capture the sheet material with the inner frame sections fitted thereon. A mechanism to hold the inner frame section in place is included.
