A project that saw the installation of Knauf Insulation’s Internal Wall Insulation System has been recognised at the National Insulation Association Awards, as being an excellent example of a Victorian mid-terrace energy improvement refurbishment.
Knauf Insulation demonstrated the benefits of its Internal Wall Insulation (IWI) System for its entry into Best Hard to Treat Project category, as part of a whole house refurbishment in Doncaster. As finalists in the awards ceremony, judges commented on the quality of the entry overall as being an excellent example of a Victorian improvement via internal insulation.
Craig O' Donnell, Business Development Manager - Residential Refurbishment at Knauf Insulation comments: “We’re very pleased to be finalists in this category with the Knauf Insulation IWI system, which provided the most effective solution to this ‘whole house – low energy’ refurbishment. The whole project has delivered exceptional energy performance and thermal comfort through a very simple and easy to use installation.
“It can be a challenge to install a system in a mid terrace house, where the attractive brick frontage is unsuitable for external wall insulation (EWI). However, the IWI System helps to simplify the process of upgrading solid masonry walls internally, so there is no scaffolding required and the external appearance of the building is maintained.”
Knauf Insulation undertook the project in Doncaster, to internally insulate the 1890’s Victorian mid terrace property, to current energy standards. The aim was to install a system that would be able to be undertaken by any competent builder to achieve an effective and efficient low energy refurbishment at a modest marginal cost over normal refurbishment. The cost effective system has helped deliver a reduction of 52 per cent in CO2 emissions, energy savings of approximately £400 per year, as well as increased thermal comfort for the homeowner. The payback period is seven years based on energy prices at the time, irrespective of any rise in cost.
Knauf Insulation’s IWI System provided the ideal solution, as it is a highly cost effective method for achieving increased energy efficiency for any type of dwelling, with no specialist skills or equipment required to install the system and it is simple to maintain. The system can upgrade a property to current Building Regulation thermal standards and beyond, consisting of composite thermally engineered studs (EcoStuds) and insulation slabs (Earthwool® EcoBatt), which can be combined to provide greater thicknesses of thermal insulation than achievable by using a single thickness. What’s more, by internally insulating a wall, the heating time for rooms is significantly reduced allowing comfort levels to be quickly reached.
