300 Brickmold Trim Series

The Kas-Kel 300 New Construction Window Series is combines high thermal efficiency and beefy design of the 220 Window Series with Brickmold Trim. For a Tradigital Look.
Other Vinyl windows have thin sashes – Ours sports a hefty 1.5″ sash (the moveable part of a window made up of the vertical and horizontal frame that holds the glass).
Jam jacks on both inner and outer parts come standard in our windows – for a consistent fit.
Draft Blocks take the place of weather stripping (which wears off over time). Our draft blocks prevent those nasty guts of cold air often associated with inferior windows.
Kas-Kel Windows have a truly sloped sill. The 15 degree angled sill allows water to run off naturally – like a traditional wood window.
This is a hefty, solidly built window frame.
Nailing fin with J-Channel, Nail fin Only, J channel filler configurations available.
