Since its introduction in 1938, fiberglass has remained as one of the pre-eminent insulation materials for both residential and commercial insulations. The insulation roll is made from fibres glass insulation materials.It has been rendering the buildings energy-efficient while reducing the utility cost and increasing the occupancy comfort. These and other features have given fibreglass rolls a leading place in many of the green building projects of the current times.
Insulation Roll and sustainable building structures
Generally, fibreglass insulation is manufacture in two major forms. One is the insulation batts and rolls and another one is blown-in loose fill form. In each of the cases, fibreglass insulation is primarily used for acoustical and thermal purposes in attics, wall cavities and other vital places in the building assemblies.The fibreglass roll insulation involves a low-cost installation process than most of the other insulating materials. Moreover, fibreglass acts as a much superior and cost-effective choice for R-value (Thermal resistance) performance in comparison to sprayed foam or cellulose options.
Energy efficiency and thermal performance
Fibreglass insulation enhances the thermal efficiency of the buildings by retaining the desired temperature inside the premises whether cooled or heated. The thermal performance of the fibreglass reduces the utility costs for the property owners apart from conserving the biofuel or non-renewable energy resources. Moreover, the insulation materials render a greater occupant comfort if other factors like the rightly-sized cooling and heating equipment are in place.
Apart from this, the application of fibreglass insulation roll provides for design flexibility. Larger amounts of rolls can be installed in some parts of the building for greater thermal performance for the areas having lower thermal values like the doors and windows.So, a greater range of R-values can be catered for. This gives the ‘specifier’ a greater number of options for complying with the energy code requirements of the area.
One can find fibreglass batt and rolls in various pre-made R values. These values range from R-8 to R-40. The loose fill fibreglass can meet any R values as it can be blown–in with the help of pneumatic devices to the required extent.
One can also install a new fibreglass roll or batt on an existing insulation for increasing the R-value in various insulation projects.
Insulation and acoustics
Fibreglass is an inert material that does not settle. Therefore, the insulation can be maintained for a long period of time without any compromise or decrease in the R-value.Keep in mind that the fibreglass batt and roll must be installed in their full thickness or attaining the R-value specified with them. Compressed fibreglass would lose an apart of its stated R-value. Installers must make sure that the insulation materials completely fill the voids and cavities and there are no gaps left. Fibreglass Insulation roll is moisture resistance, fire resistance and acts as a natural sound absorbent. Moreover, due to its ability to be recycled, it is an environment–friendly material with great insulation properties.
