Why Cellulose Insulation is Better than Fiberglass Insulation?

Cellulose insulation is one of the warmest materials available and also has a fantastic density which puts it right up there as one of the best performing materials. Cellulose insulation is also extremely eco-friendly – it is made from natural fibers which are recycled from the newspaper. These natural fibers last much longer than man-made fibers which have a much shorter life span. Cellulose insulation is also made in Ireland, registered with the Irish Agrément Board, NSAI.
Registered by BSI quality assurance, to produce cellulose fibre thermal insulation. Also accredited by the Irish Agrement Board (IAB), cert number 07/0285.
Cellulose insulation is made from cellulose fibre derived from waste newsprint that is treated fire retardant and biocide salts.

Cellulose Insulation Characteristics/Specifications
- Cellulose insulation is natural insulation, designed to minimize energy loss more effectively than mineral fibers.
- Cellulose insulation is blown into walls, roofs and floors, creating a continuous draught-proof layer with excellent thermal and acoustic properties. It helps create a comfortable living environment free from HCFC’s, VOC’s or other toxic substances.
- Cellulose insulation is made from discarded newspaper, a major component of the waste stream, easing pressure on landfill sites and putting to good use an otherwise wasted resource.
- Cellulose insulation uses borate-based fire retardants which have less toxicity than common salt, provides a high level of fire resistance and enables ecocel to easily meet all fire protection standards (tested to BS5803) and in effect to act as a fire stop.
- Cellulose insulation has an impressive thermal conductivity value of 0.038 W/Mk at a density of 26.7 kg/m3, which remains stable over a wide range of 3 temperatures. However, the real world performance is further enhanced by its superior resistance to air infiltration resulting in a 25% overall improvement in energy efficiency.
- Cellulose insulation components are non-toxic, non-irritant and environmentally benign. It also requires relatively little energy in production and does not pollute water, air or soil. It can easily be removed and reused, and can ultimately be returned to the earth (i.e. composted).
- Cellulose insulation is blown by trained personnel into walls and ceilings using a pressurized installation system which ensures complete filling of cavities to the correct density.
