EW brings the functionality and style of bifold technology to smaller-scale external openings. An exciting alternative to conventional window styles in the widest variety of applications.
Best Deal Windows EW is an external bifolding window hardware system for windows with a maximum sash weight up to 20 kilograms. 
EW is suitable for a range of smaller residential and commercial openings including counters and serveries, as an alternative  to conventional windows in bedrooms or living areas, or anywhere the larger panel capacity of one of Best Deal Windows bifold door systems is not required.
EW comes complete with aluminium and timber lineal kits and can be fully factory assembled prior to installation.

Impressive water performance ratings are achievable from outward opening windows with the system achieving its superior rain and wind resistance in part from the way window panel to close snugly against weather seals. Resistance to air infiltration  up to fifty times better than a sliding window, and impressive acoustic sealing qualities are additional benefits.
