Thermo-Cell Industries Limited is a manufacturer of thermal and acoustical insulation, specialty fibres and hydroseeding mulch. Thermo-Cell is currently one of the largest manufacturers of cellulose insulation in Canada and operates two manufacturing facilities. Products are actively marketed under the "Weathershield Insulation" and "Celumulch" trademarks, throughout Central and Eastern Canada and the Northeastern United States.

Weathershield Insulation is manufactured from recycled newsprint which is treated with fire retardant chemical. The organic, short and hollow nature of the fibres is non-irritating and provides excellent sound attenuation properties as well as superior resistance to heat loss, compared to rock wool and fibre glass insulation. Weathershield will not release any harmful emissions and is resistant to mold, mildew and rot as well as insects, mice and other vermin.

Celumulch is a hydroseeding mulch designed to be used in roadside seeding and general landscape seeding applications. It is produced from recycled paper and paperboard stock which is dyed green. The unique benefits of using Celumulch are that it protects seeded areas against evaporation, erosion and foraging birds and animals.
