Our Chimney Blocks:
Stop air from infiltrating the balance pocket and leaking around the sash.
Reduce negative air pressure.
Reduce wind noise and condensation at the meeting rail
Available with single hole, dual-hole, off-center holes and no holes.
Used with block and tackle, spiral and constant force balance systems.
Available in custom sizes and can accommodate any window and balance combination.
In order to decrease air infiltration it is extremely important to follow these steps:
Position the chimney blocks on the balance for the lower (inner) sash. This prevents much of the outside air from entering through weep slots in the sill, traveling up the jamb pocket and coming through the interlock area and into the room.
They should be positioned about 2”-4” below the tilt latches for maximum benefit.
