Single Hung
Our single hung offers great performance
and smooth operation. The 5900 has block
and tackle balances, a tilt-in sash, recessed
tilt latches, automatic sill locks and dual pull
rails. Our air infiltration is an amazingly low
.03! This great performance is enhanced
with features like a sloped sill, dual weather-
stripping and a center interlock.
