Window Fitters Guide to Window Installation 116 ©2022 AWDI, LLC Do not reproduce without permission Installing Tilt ‘n Turn Windows Tilt ‘n Turn windows provide two open positions: the tilt position provides draft-free ventilation and worry free rain protection. In the turn position, tilt and turn windows act like casement windows, swinging their full glass area open. These windows have dual hardware to allow them to pivot in from the top using bottom hinge system, or swing from the side using a jamb hinge setup. The control is obtained using the handle which when turned one way will allow the tilt, and turned the other will allow the in-swing. The complete hardware system of a Tilt ‘n Turn window is necessarily complex and precision requiring tight tolerances between the operating sash and the frame to engage the hardware and maintain weather tightness. In addition, because they open to the inside, the tolerances and the locking precision is critical because the inward air pressure from wind is forcing against the closure rather than aiding it as would be the case in an outswing casement or awning window. Precision is necessary for proper weather seal. 5 Critical Requirements for Proper Installation 1. Plumb, Level, Square, and Planar Because of the multiple locations of operating hardware (hinge, lock, tilt, roll, etc.) each opening critically needs to be plumb (precisely vertical), Level, Square (right angles at each corner), Planar (perfectly flush and not contorted at all). Any deviances might impact the proper operation. It is more critical than with any other type of window. 2. Properly supported Use of Capture blocks. Due to the weight, and offset sash, neoprene or plastic capture blocks (support blocks, sized to fit within the window or door frame) are to be used under the sill and at key hinge points at jambs - all near the fasten point. We recommend proper shimming and pre-shimming using air bag shims for proper adjustment prior to fastening, rather than hammering Proper shimming and sup- port will allow the unit to “float” in the opening to preserve operational tolerances. 3. Wood surround for Installation All openings shall be rough framing or an applied wood surround for solid support and anchoring. Replacement will need to be full frame removal of the old window, and if that removal cannot get the opening down to the rough opening framing, a wood buck is prescribed. 4. Weather Sealing of the opening needs to be done prior to window placement or mounting. All flashing and weather sealing of the opening will be done prior to the window install. Then the unit will be properly sealed (backer rod, foam, sealant, etc.) to the opening ands against the weather. 5. Fastening using Mounting Clips Use of mounting clips is recommended rather than through the frame anchors to accommodate the most opening variances, and to discourage anchors which can distort the frame when over-tightened.
