How do you heat a grow tent enclosure

My plan for uvb is to sew a mesh pannel onto the roof to allow uv in and to secure the fixture to but I’m not sure if putting a heat bulb in a similar set up would cause the mesh to heat to the point the mesh melts the tent? Does anyone have experience keeping reptiles in grow tents?
