Englerts Series 1100 system is designed for sloped roofs and other exterior sur faces of light commercial and residential projects. The 1100 profile, with concealed clips and fasteners, requires no mechanical seaming or separate seam cap. The narrow standing seam can be detailed to provide a smooth transition from roof to fascia or mansard. The snap-lock panels offer the designer an architectural system for creating clean roof lines with minimum of shadows and textures. Special clips allow smooth expansion and contraction without binding.
