Several points should be kept in mind when selling and installing berbers…

Seams are best made with either 6-inch wide seaming tape or special steaming irons, to help flatten seam peaking.
Seams should be sealed to reduce fraying the carpet fibers along the seams.

Power stretching equipment must be used with berber carpets to overcome the stiffness of the backing and achieve the required amount of stretch.

Berbers usually have more pronounced seam peaking than pile-cut carpets due to their thicker backings.

Carpet cushion (pad) used under berbers should be thin (1/4″-7/16″ recommended) and firm (8-lb. Density recommended). The minimum acceptable cushion is 7/16″, 6-lb. Density. Experience has shown that the thicker backings required for berber carpet can break down and deteriorate faster if not supported by the firm cushion. Thick, soft carpet cushion can cause wrinkling and seam delamination in berbers.

Finally, the thinner cushions recommended for berbers will result in a noticeable gap between baseboards and the edge of the carpet if baseboards are set too high. A baseboard height of ¼” to 3/8″ is best.

Since berber carpet has different physical characteristics from most other carpets, several points should be kept in mind when selling and installing berbers.

The thick yarn bundle required to produce the desired berber appearance creates a thicker backing “sandwich”. This “sandwich” consists of two woven layers of polypropylene backing material encapsulating the yarn bundle in latex. The thicker backing and greater amount makes berber carpets stiffer and harder to work with.

Therefore, berber carpets cost more to install because they require extra time to cut, handle, and seam.
