Application
An alternative to a traditional hardwood sill is the Brio 'patent applied' 95 HS Hybrid Self Draining Sill, a composite construction of aluminium and hardwood. Hardwood is used on the exposed visual surfaces leaving the aluminium to cope with water dispersion and contact. The result is a longer lasting door unit with conservation as an added bonus, since the 95HS uses a fraction of the hardwood as used in traditional sills. An aluminium external tread is also available for those high traffic applications where a durable low maintenance solution is required.

The 95HS Hybrid Self Draining Sill has been successfully tested to comply with Australian Standard AS2047 – 1999: Windows in buildings – selection and installation, by a third party NATA accredited laboratory as part of a complete folding door system fitted with Weatherfold 4s hardware.
