Knauf Insulation, the UK's leading manufacturer of insulation products, has supported the Energy Savings Trust (EST) by providing its products to create the energy efficient home unveiled at the Grand Design’s Live Show in ExCeL.
The house - which features products from the Crown glass mineral wool range in the roof, floor and walls – has been created by Bere Architects as a way to show consumers how to save money on fuel bills and reduce their household carbon emission. The house acts as a model to show how simple measures, such as installing loft and cavity wall insulation in a home, can reduce annual fuel bills by an average of £430 and carbon emissions by almost three tonnes per year.
For homeowners the quickest and most cost effective way to instantly reduce their home’s carbon emissions is through the inclusion of insulation, but some are discouraged by the initial cost. The energy efficient home demonstrated that the cost of installation can be saved through energy bills in less than a year. What’s more, Knauf Insulation’s Crown glass mineral wool range is made using a high percentage of recycled glass and processed using techniques which mean that during its normal life, it will typically save more than 1000 times the energy used to produce it.
Each of the house’s wall cavities has been filled with 65mm of Crown DriTherm Cavity Slab which is able to achieve a U-value of 0.27 (the minimum permitted in 2006’s revised Building Regulations). Further more, this is the only range of products which can be used within all block constructions – dense, medium dense, standard aircrete and lightweight aircrete.
Crown Loft Roll 44 has been used in both the floor and ceiling insulation at 150mm thickness in between the timber floor joists and above the ceiling joists, and at 100mm thickness between the ceiling joists. Crown Rafter Roll 32 has been used at 100mm thickness between the roof rafters while 140mm of Crown FrameTherm Slab has been used between the internal studwork. Every product within the Crown range has excellent thermal and acoustic properties and are friction fitted to eliminate air gaps, thus reducing thermal escape.
Justin Bere, director of Bere Architects, said: “When designing the house we approached Knauf Insulation as its products are EST recommended, which meant we were guaranteed energy saving products. To highlight the energy efficient modifications the existing building structure has been coloured white while the additions are in true colour. This works to help home owners see how many products are available on the market which are easily accessible, affordable and simple to install.”
Phil Rigby, Insulation Academy Manager from Knauf Insulation, said: “Energy efficient modifications to existing dwellings can be installed quickly and simply while achieving outstanding results. The EST stand helps to highlight products such as the Crown DriTherm range which is classified as Zero Ozone Depletion Potential (ODP) and Zero Global Warming Potential (GWP) as outlined in The Code for Sustainable Homes and EcoHomes, meaning they are suitable for the production of zero carbon homes.”
