Green Retrofit As much as 50% of air loss in well insulated buildings occurs around windows and doors. Although a revolving door offers the best protection from air loss occurring through the entry of a building and can save you considerably on energy cost, there is always room for improvement. As new technological innovations have become available, we now offer a Green Retrofit package that can improve the energy efficiency of a revolving door even further. The Green Retrofit package consists of a number of improvements. As of 2013 these improvements are offered standard on all new doors leaving our factory. However if you have a previously installed door, upgra­ ding can save cost and improve the sustainability of your building. Each improvement can be ordered separately or as a complete package, allowing you to pick and choose what measures suit your entry’s requirements best.

However it is impos­ sible to prevent some air being lost even between the horsehair. Our new draught strip combines the aesthe­ tic look of horsehair with the improved air permea­ ility b characteristics of a rubber inlay to improve air tightness by 30%. Similarly, improved air tightness of our ceiling lighting helps prevent energy...
