National Fiber''s Cel-Pak is a high quality, all borate, loose fill cellulose insulation for blowing caps in attics and dense packing in walls and ceiling cavities either for retrofit or new construction. The borate infused cellulose offers exceptional thermal properties that is 40 times better than fiberglass. Dense-packing cellulose continues to retain heat in your home or building no matter how cold it gets - fiberglass loses its effectiveness when the temperature drops below freezing. The borates also act as a natural fire retardant that actually protects your home better than fiberglass or foam insulations. In addition, because cellulose fills in the gaps and leaves no voids, the high density material absorbs sound leaving your home or building protected. Since airflow accounts for 98 of the moisture movement in a structure, the density of cellulose blocks that movement and does not require vapor barriers. The borates also act as a natural mold inhibitor to protect the substrates it is in contact with. These same borates also repel insects and vermin, such as mice, cockroaches, and termites.
Hydro-Spray Mulch is a high quality 100 paper mulch designed for use in Hydro-seeding sprayers. The mulch is made from over-issue newsprint - yesterdays unsold newspapers - hand sorted to remove glossy stocks, plastic and wire to make the cleanest mulch available.
