Our History - There had to be a better way!
In 2003 the company that evolved into SlottedSection consisted mainly of Peter Dudley and Peter Merrien who had been in the insulation and ducting business for over 40 years and together for 28 years.
They found that insulating and weatherproofing external pipework and ductwork in the traditional method with mineral wool and weatherproofing with either PIB (polyisobutyline) or aluminium cladding, was problematic. The air leakage from the ductwork was a major problem as it would pressurise the sealed PIB or Aluminium Cladding and ultimately burst the seams allowing water into the mineral wool which would become saturated and fall off.
They would normally have to repair the PIB projects prior to the one year retention release period in order to obtain the retention for the whole project. This was costly both in monetary terms and labour time taken from newer projects.
