99HSA Hybrid Self Draining Sill
The Brio 99HSA Hybrid Sill is an alternative to a traditional hardwood sill for exterior outward opening Weatherfold 4s 150 system. The self draining sill has an aluminium tread with a built in channel for guides. Hardwood can be inserted into the rear of the sill for the internal, visual surfaces leaving the aluminium to cope with water dispersion and contact. The result is a longer lasting bifold unit with conservation as an added bonus, since the 99HSA uses a fraction of the hardwood as used in traditional sills. Suitable with or without the Brio 612 Retractable Pleated Insect Screen.
