Best Practice Installation

TamlynWrap® Drainable Wrap or Tamlyn ProSelect Commercial Wrap should always be lapped in shingle fashion starting from the lowest point. This means that you start from the bottom of the wall and work your way up. Proper shingling is required to shed water and to prevent water from entering the wall system.

  • Unroll TamlynWrap® Drainable Wrap with spacers facing to the exterior and fasten to sheathing with cap- fasteners.

  • Use commonly available scissors to cut TamlynWrap® Drainable Wrap. Use of utility knife will break the bond of filaments (spacers).

  • Fasteners should provide a minimum 1/2" penetration into the nail base and be spaced approximately 12 to 18 inches apart along the horizontal and vertical laps through XtremeSeam Tape. Fasten every 3 sq. ft. everywhere else.

  • TamlynWrap® Drainable Wrap should be installed shingle lap fashion (i.e. begin installation at the base of the wall assembly).

  • Extend housewrap a minimum 2 inches over sill plate.

  • Overlap all horizontal seams by at least 6 inches, all vertical seams by at least 6 inches and corners by 12 inches.

  • Be sure that the housewrap installation and flashing provide for positive drainage to the exterior of the assembly.

  • Do not allow the housewrap to be exposed to sunlight in excess of 120 days. recommended coverage within 30 days.

  • When using TamlynWrap® Drainable Wrap as primary air barrier and for 25 year warranty tape all seams using XtremeSeam Tape, ensuring the area is dry and clean and it is recommended that for best adhesion a hard roller or hand applicator is used.


XtremeSeam Tape

STEP 1
Unroll first course of TamlynWrap® Drainable Wrap with spacers facing the exterior and fasten to sheathing with cap- fasteners. XtremeSeam Tape is applied to the first course by removing one side of the release paper and for best results lay down with a hard roller or hand applicator.

STEP 2
With this in-place unroll the next course of TamlynWrap® Drainable Wrap maintaining the required 6” of overlap, with fastening stopping 9” from the bottom of this course allowing for it to be folded up.

Fold upper layer of TamlynWrap® up and remove the release paper on the XtremeSeam Tape, then press the layers together, for best results use a hard roller or hand applicator. Then complete fastening along the seam.


Flashing Openings - Modified "I" Method

Rough Opening
Cut across the header with scissors, then down the center of the opening. Make a horizontal cut and two angled cuts to the sill. Cut from the corners of the header 45 degrees away from the window to create the top tab. Fasten the tabs down, then fold up the top tab, and tuck it out of the way.

Sill Flashing
9” wide XtremeFlashing is recommended for sill installation. Apply XtremeSealantTM at the jambs and head before setting the window.

Set Window
Set the window into the rough opening, level, and fasten to the structure per window manufacturer’s recommendation. Membrane should be visible below the sill flange. Do Not apply XtremeFlashing over the bottom flange. This area is left open to allow water to drain in the event of a window leak.

Jamb Flashing
Adhere vertical sections of XtremeFlashing over the jamb (side) flanges and to the TamlynWrap® with a hard roller or hand applicator. The vertical flashing should overlap the flashing at the sill (bottom) and extend approximately 3” above the rough opening at the head (top), preferably onto the exposed sheathing.

Head Flashing
Adhere XtremeFlashing to the header flange and to the sheathing. Head (top) section must extend beyond jamb (side) sections on either side. Jamb (side) sections should not extend above the head (top) section.

Final Steps
When done, fold the top tab of TamlynWrap® back in place over the head (top) section of XtremeFlashing and tape or fasten it in place. XtremeFlashing has self-sealing properties that allow it to seal arround nails, screws or fasteners used when siding the house.
