Hibernia Wool Carpet Installation Recommendations


All Hibernia Wool Carpets are subjected to multiple inspections in the manufacturing and shipping process. Final inspection of the carpet is the responsibility of the installation contractor. Claims for carpeting installed with visible defects will not be considered by the manufacturer.


Hibernia Wool Carpeting should be laid according to the installation and seaming diagram designed by the retailer/contractor. Extreme care should be taken to eliminate seams in the carpet wherever possible. The installation diagram should direct all seams in the direction of the light source (sliding doors or windows) whenever possible. All carpet must be installed with the nap or face yarn in the same direction. Hibernia wool carpet is marked on the backing to help determine pile direction.


All Hibernia Wool Carpets have factory edges to prevent damage during shipping. Some Hibernia carpets must be row cut to remove the factory edge. Other Hibernia carpets that have adequate surface pile can be back cut. All cut edges must be sealed on both sides of the seam with Roberts seam sealer or a comparable product. Extreme care should be taken to insure that the seam sealer glue does not make contact with the carpet face yarn. Failure to seal the seam edges will result in yarn loss and poor seam quality.

Use of a premium quality hot melt seaming tape is recommended. With low profile carpet a special seam tape should be used. The seaming iron should have a proper heat shield and the iron heat setting should be set at a medium heat level. The Iron should be moved at a speed that will completely melt the hot melt adhesive. The seam should be made over a firm surface and the iron should be run in the same direction as the face pile of the carpet, never against the pile.

When pressing the carpet into the hot melt adhesive, use a tractor or skate to insure proper bonding. Overheating the seaming tape in an attempt to speed up seaming can damage the wool face fiber as well as the backing. This will cause distortion to the seam and discoloration to the carpet. A weighted piece of wood with holes should be used to weight the seam rather than using a metal toolbox tray, which can retain heat. Also soil and rust form the bottom of the tray will discolor the face of the carpet.


Please refer to the following technical bulletins for specific information:
CRI Bulletin No. 66 - Floor Preparation
CRI Bulletin No. 108 - Stretch-in Installation

The face of the seam areas should be completely cool before the carpet is power stretched. Premium tackless strip must be securely fastened to the floor with the pins pointing to the wall. The gully space between the wall and the tackless strip should not exceed 3/8". The carpet should be stretched approximately 1-1/2% in length (1-1/2 feet in 100 feet) and a snug fit in the width is recommended. A power stretcher must be used. For some Hibernia carpets with a low profile or a low pile height, a cotton head attachment to the stretcher is required. Sufficient stretch cannot be obtained using a mini-stretcher (pick stretcher attachment) or a knee kicker. Again, with low profile and pile height carpets, a cotton head attachment is required. The carpet must be secure and tight against all walls for completion of stretch type installation.


Hibernia Woolen Mills does not recommend nor will it warrant Hibernia Wool Carpet glued directly to the floor.


Hibernia carpets may be installed using the double glue installation procedure. Follow the specific instructions of the double glue padding and adhesive manufacturers. Extreme care should be used with the placement of carpet into the adhesive allowing for proper glue tack. For proper seaming for double stick installation follow the same procedures as stretch-in method of installation.


Hibernia Woolen Mills recommends the use of new carpet padding for all installations. All carpet padding must meet specific density factors.

Examples of proper padding:

  • 40 ounce synthetic fiber padding (undyed)
  • minimum 8 lb. density, maximum 3/8" thickness foam or rebond pad
  • solid sponge rubber pad 1/4" thickness

If the installation is over radiant heat, floor padding must be approved by the radiant heating contractor.

Special note: Some carpet padding will excrete an odor that will dissipate over time. This odor is not from the carpeting because we triple scour Hibernia Wool Carpet.

All Hibernia carpets should be installed by a licensed flooring contractor.
