BIBS is blown in dry, and tests have shown that walls insulated with a BIBS system are significantly better filled than those insulated using other forms of fiberglass insulation such as batts because of the effective coverage obtained by this method of application. One variation of fiberglass loose-fill insulation is the Blow-In-Blanket System® (BIBS). Loose-fill insulation must be applied using an insulation-blowing machine in either open-blow applications (such as attic spaces) or closed-cavity applications (such as those found inside existing walls or covered attic floors). Most manufacturers use up tp 40% to 60% recycled glass content. R-38 batts for 12-inch (304-mm) spaces are also available.įiberglass insulation is made from molten glass that is spun or blown into fibers. High-density batts for a 2 by 6-inch (51 by 152 mm) frame wall offer R-21, and high-density batts for an 8.5-inch (216-mm) spaces yield about an R-30 value. A medium-density batt offers R-13 for the same thickness. High-density fiberglass batts for a 2 by 4-inch (51 by 102 millimeter ) stud-framed wall has an R-15 value, compared to R-11 for "low density" types. The denser products are intended for insulating areas with limited cavity space, such as cathedral ceilings. Manufacturers now produce medium- and high-density fiberglass batt insulation products that have slightly higher R-values than the standard batts. It's commonly used in many different forms of insulation: blanket (batts and rolls), loose-fill, and is also available as rigid boards and duct insulation. The installation of cavity wall insulation in all three towers is expected to be completed by the end of September 2010.Fiberglass consists of extremely fine glass fibers and is one of the most ubiquitous insulation materials. The installation itself is a speedy process, which does not require manual handling and causes minimal disturbance to the residents”. We had to adapt the installing technique and the machine setting for the task, but it is expected at a project of this scale. However, this project is about multi-storey social housing buildings. Gary Cox, Managing Director of UK Homes Insulation, the installer of the insulation added “Cavity wall insulation is a popular cost effective solution for one or two storey single dwelling houses, mostly in the private domestic sector. Residents have been involved in the scheme from the start, with representatives from each block working with the design consultants, using their local knowledge to help steer the proposals for the benefit of all who live there.Īs well as Rockwool EnergySaver, other Rockwool products to be used in the project include external wall insulation, roofing boards, partition walls, Rockfon ceiling tiles and Rockpanel – an external wall cladding chosen by the residents that increases the aesthetic as well as thermal value of the buildings. The £12.2 million regeneration project is intended to extend the life of the towers for another 40 years through a thorough thermal and visual upgrade. The Edward Wood Estate is a 1960’s social housing development that is to be refurbished rather than demolished and replaced. ![]() Working closely with our approved installer UK Homes Insulation we have engineered a quick and effective way of providing cavity wall insulation to residents of the Edward Woods Estate with the minimum amount of disturbance”. However, the Edward Woods Estate project, filling 1380 cavities with insulation weighing the equivalent of 36 mini coopers, is truly exceptional in scale.Īndrew Champ, Business Development Director at Rockwool said “This clearly is a massive undertaking, and has involved meticulous planning from the start. ![]() The stone wool is pumped from machines set in the back of a van adjacent to the building through a hose. ![]() The practice of filling cavities with granulate stone wool insulation is now a common sight across Britain, with homeowners utilising measures to increase the energy efficiency of their homes with minimum cost and disturbance.
