When considering insulation systems, consideration should also be given to the Environment.
BRE paper IP 2/93 outlines considerations to be made when refurbishment projects are carried out.
British Steel Engineering had several of their roof bays weatherproofed and insulated using Sprayed Foam and Elastomeric weather coating applied externally. The project was monitored before and after application by the D.O.E. (BRECSU) and on this 20,000+ m2 roof, the payback period was calculated at 2.4 years.
In addition, the C02 emission savings have now been calculated and amount to savings of 90kg of C02 per sq. metre per year.
There are Government plans for Energy Levies and MPI systems will help Industrial Energy users meet their responsibilities.
