What we represent

We want to give Architects, Surveyors and Design and Build professionals the reassurance of knowing that the best products are being installed to the required standards while complying with all relevant codes of practice.

More than just a name – a guarantee

At a time of economic uncertainty for all those in the construction industry, an insured guarantee is a highly valuable asset. A BMI Icopal roof installed by an IMA contractor carries an approved guarantee which provides peace of mind for up to 35 years, depending on product and specification. The full range of guarantees, covering both materials and workmanship, provides unrivalled protection and demonstrates BMI Icopal’s confidence in both its product range and in IMA contractors’ skills and workmanship.
