HTA is a synthetic material designed to remain unaffected by corrosion in utility supplies in buildings. Because of the product's nature, scaling related problems are much less significant than with other metal pipe systems. This observation is particularly true in areas with soft water (very pure water). HTA system is rated Bs1d0 as certified by European classification (Euroclasses) issued by the LNE. Non flammable, no smoke and no droplets.
