Cellulose Fibre Insulation is an environmentally responsible choice for insulating. Its long lasting superior performance helps to keep your home cool in summer and warm in winter.
Maybe that is all you want or need to know, but here are the technical properties that can help make it easier to understand, why cellulose fibre insulation is your best choice.
Cellulose fibre maintains an almost constant R-Value over the full range of densities at which it can be installed, whereas mineral fibre products suffer dramatic losses in R-Value as the installed density decreases.
Cellulose fibre, due to its perfect fit and greater density, inhibits air movement; whereas tests have proven that air movement through and around light density, poorly fitted fibre glass insulation can reduce its thermal effectiveness by up to 50%.
Sound waves travel throughout the empty cavities in your building and uses these empty spaces to amplify. Using cellulose fibre to fill these cavities effectively reduces areas where sound can travel. There are four performances to consider when measuring the effectiveness.
Cellulose fibre’s ability to transport moisture to a surface where it can evaporate is most important in keeping moisture levels low and insulation effectiveness high. It passes ASTM C739 Moisture Vapor Absorption test.
Cellulose fibre insulation has been treated with Borates for fire retardancy. It will only char under direct fire exposure and will provide longer heat protection to adjacent building materials. It has a Class 1 Fire Rating where flame spread is <25 and smoke development is <50. It is important to note that when cellulose fibre burns, it does not emit toxic chemicals.
The performance requirements of its CGSB standard are ensured. That's good news because it means that cellulose fibre insulation provides long term protection against wood decay, fungal growth, insects, mice and other vermin.
A less well known function of these borates is their ability to prevent formation of mould, mildew and wood rot. This unique characteristic of borates is becoming increasingly valuable as the trend toward tighter house construction increases the potential for moisture accumulation within the building envelope.
