Why choose Cellulose Insulation?
We believe in using solutions that are good for both people and the planet — and cellulose delivers on both fronts.
Cellulose insulation is one of the most sustainable, effective, and safe ways to insulate your home. It provides year-round comfort while reducing your carbon footprint.
Made from 85% recycled paper – more recycled material than any other commercially available insulation – and treated with natural fire retardants.
Small pieces of paper are ‘fiberized’ so they can be densely packed into small places to stop airflow. It can store and release humidity without affecting its thermal performance.
Cellulose doesn’t use any greenhouse gases as propellants and its components of cellulose are natural and biodegradable. And, its hygroscopic properties regulate humidity, contributing to a healthy, comfortable living environment.
Key Benefits at a Glance:
Exceptional Thermal Performance – Keeps heat in during winter and out during summer.
Environmentally Friendly – Highest recycled content of any insulation and no fossil fuels are required to make it, unlike rock wool or mineral wool.
Safe & Healthy – Treated with non-toxic fire retardants and pest deterrents.
Superior Soundproofing – Dense structure absorbs noise.
Long-Lasting – Will last the life of your building. You don’t need to replace it or top it up after a few years.
Hygroscopic – Absorbs and releases moisture throughout the year and helps to keep air healthy and prevent mould.
Grant Eligible – SEAI-approved for attic and wall insulation grants.
What is Cellulose Insulation Made of?
Environmental Advantages
85% recycled paper
Less landfill, less waste.
No greenhouse gases
used as propellants.
Biodegradable
at the end of its life.
Low embodied energy
due to minimal processing and local sourcing.
Fire, Pest & Mould Resistance
Despite being made from paper, cellulose insulation is not flammable.
It is treated with safe, natural fire retardants such as boric acid and magnesium hydroxide. These also act as:
- Pest deterrents (against rodents and insects)
- Mould inhibitors
How Cellulose Insulation Works?
Cellulose insulation is blown or sprayed into your attic, walls, or floors. This allows it to:
- Fill every gap, crack, and crevice to prevent air leaks.
- Provide a dense, seamless thermal barrier.
- Regulate humidity naturally thanks to its hygroscopic properties.
Where It’s Used:
- It can be used in existing homes, new constructions, apartments and commercial buildings.
- It is suitable for timber framed-homes, attics and lofts.
- It can be blown as loose-fill insulation into attic cavities, packed into walls and floors
- It helps increase heat retention.
- It dampens noise levels.
Is Cellulose Insulation Safe for Your Home?
In short, yes! Cellulose is made from recycled paper but it does not make your home vulnerable to fire.
This is because it is treated with fire retardants such as magnesium hydroxide, gypsum, borax, and boric acid. By doing so, it meets building regulations requirements. And, because it is fire retardant, it can help control the spread of fire.

How Does Cellulose Compare to other type of Insulation?
| Feature | Cellulose | Spray Foam | Fibreglass |
| Thermal Performance | ★★★★☆ | ★★★★★ | ★★★☆☆ |
| Soundproofing | Excellent | Excellent | Good |
| Eco-Friendly | ★★★★★ | ★★☆☆☆ | ★★☆☆☆ |
| Air Seal | Very Good | Excellent | Fair |

The cost of cellulose insulation beats any other form of insulation available on the market when you look at the ratio of EUR /U-Value! Its energy efficiency will reduce energy costs and lower carbon emissions.
Thermal Mass of Cellulose Insulation
Cellulose is a dense product which makes it thermally massive and can absorb heat before transferring it.
The followings are the times for heat to go through the insulation material (350mm thick). In the below example, we look at the thermal inertia, the insulation is at floor level in the attic floor.
- Cellulose insulation: 9.5 hours
- Rock wool: 5 hours
- Fiberglass: 3.6 hours
