Replacement and Retrofit Variations: Frame-In vs. Frame-Out; Wall Constructions; and Window Frame Materials

STANDARDS AND PRACTICES

There are many wall constructions (wood frame, masonry,and concrete block) along with vinyl, wood, and metal windows that are to be removed, and vinyl, wood, compositeand metal windows to be mounted as replacement.

These variations require individual considerations whenremoving the old windows; such as whether you leave theold frame in place, or remove it completely.

These wall construction and window frame materials alsoimpact how you remove the old window, how you install thenew windows, and how you flash and seal the opening toprevent air and water infiltration.

It’s important how you install so you can preserve the in-labperformance of the new product when placed in-service.With all these variations, the basic approach is the same.

What needs to be decided first is whether the new windowmounts against the old window frame, preserving the exist-ing weather barrier interfaces already established betweenthe left-in place window and the wall; or does the new win-dow go into an opening where the old frame is gone and allthe weather barriers need to be re-constructed.

The following shows examples of different approaches - withthe common goal of proper weather management.

Interior Stop(Outside-In)Operating Sash removed from exterior by trimmingdown blindstop. Operating balances,ropes, pulleys, tracksremoved to outside.Interior stop left-in-place. Windowinstalled from exterior,against inside stopwith full exterior wrapto cover exterior stop.

WOOD WINDOW Frame In and Frame Out

STEEL WINDOW Windows set in Concrete, Stucco or Masonry

Frame In - B

Frame Out (Integral J-Channel)

Blind Stop(Inside-Out)Basic sash pocketreplacement. TheOperating Sash and balance system(Ropes, Pulleys, and Weights) are disconnected andremoved to inside (or aluminumtrack/spring). The New window isinstalled into the sash pocket from theinterior (head expanderas needed) with optionalwrap of exterior trim.

Rough OpeningBrick mold, old frame & sash pocket removed. Sheathingrevealed to width of casing. New, finned window installedwith new brick mold exteriorcasing over new fin to butt siding. Interior trimmed as needed. The Integral J-Channelcan allow re-application of thesiding and create effective water management.

FIN MOUNTED WINDOW Frame Cut-Out

Box Frame

Mounting Fin Cutout. Sawsall cuts through nailingfin of old window on all 4-sides. The fin remains are leftin place. A block is used tomake an interior “stop” andthe new window is installedfrom the outside against thestop. Backer Rod andsealant, J-Channel or cap-ping is installed to seal theoutside.

UNIVERSAL FIN WINDOW REPLACEMENT Box Frame Pocket Install

Box Frame

Creating BlindstopRather than saws-all cutsaround old window to leave the fin in place, removing old trim and siding to expose the old finned window allows full removal. Replacing the removed trim and/or siding with new trim, 3/8” wider, to project into the opening, creates a “blindstop” allowing a Pocket Install from the inside. Using shims under the window and cap nails to secure the sill flashing in place provides proper, functional drainage.

Wood Frame-In or Frame-Out

Wood Openings Whether the old win-dow frame is left inor removed, a pvcliner works like areceptor system. The liner can beinstalled plumb andsquare with allweather barriers re-established. Thenthe new window isinstalled into theliner weather tight.

Concrete Frame-In

Masonry OpeningsWhen windows are installed into masonry openings of block and stucco,removal leaves a messthat’s difficult to makeweather tight. A rigid linersystem overcomes thedestruction of removal and allows a good performing installation.

Frame-Out

Frame-In

Wood Buck SurroundThe old frame is removed, exposing the wall gap between the stucco coating and the interior. Taperedwood bucks are fastened to theunderlying block walls with cementnails to provide a secure mountingsurface. The wood bucks areapplied along header and jambs.Any gap in the sill can be filledwith quick-set compound (fast drying leveling cement) to makesure a level surface is provided for the sill buck, unless it’s a pre-formed sill with taper.

Butt to old frame fromExteriorAll panels are removed down tothe left-in-place frame. The newwindow, unequal legged, ismounted against the old framefrom the outside to make aweathertight installation withthe new window covering theold frame. Wood or cellular pvctrim blocks can be applied onthe inside to level out the spacebetween the new window andthe old sheetrock return, andallow trim to be applied to finish the install.
