Windsor’s Pinnacle clad double-hung product has traditionally offered a compression jambliner. This flex-back design has been very popular due to the fact that it can be adjusted during installation. However, in recent years, there have been several technological advances that now allow us to offer a design providing a CONCEALED jambliner. The concealed jambliner option reveals more wood from the interior while allowing a fully clad exterior. In addition, the new design allows us to build larger sizes because it utilizes a full-size block and tackle.
Along with improved appearance, the concealed jambliner option will provide the following benefits:
- With this new offering, raised sill stops will now be incorporated into ALL Pinnacle clad double-hung windows, including both the compression jambliner option and the concealed jambliner option. The sill stop will be flush with the bottom of the finger-pull, providing better performance.
- Half-screens will be available on the concealed jambliner option.
- A wood head parting stop replaces a vinyl parting stop.
- A new full-size inverted block and tackle provides support for a heavier sash, allowing for future production of larger sizes.
- Interior jamb covers are available in all wood species, providing more wood on the interior and less plastic. Exterior jamb covers will be available in finishes that match the aluminum.
- Jamb jacks provide the ability to make future adjustments after settling.
- On windows ordered with the concealed jambliner option, the head frame corners are now secured with corner keys, injected silicone and screws for improved stability. Therefore, the corner gaskets are no longer needed.
- A trim identification line on the side and head inside stops provides easy alignment during installation.
- The sill bottom rail weather-strip will now be available in two shades, bronze and beige – one to blend in with lighter clad colors and the other to blend with darker clad colors.
- Structural changes of the concealed jambliner provide improved DP ratings.
- The picture window back-out strip is now color-matched aluminum for a consistent exterior appearance.

Please note: Clad single-hung oriel windows will now only be available with the concealed jambliner option. The concealed jambliner option is NOT available in the Pinnacle Impact product, Win-Pac or the Legend HBR product.
