<p><font size="1">The National Association of Chimney Engineers (N.A.C.E. Ltd.) was formed in
1982 by a group of independent companies specialising in chimney lining. Their
purpose was to set and enforce national standards of workmanship and quality
of product in this demanding sector of the construction industry, culminating
in the recent introduction of NVQs (Chimney Engineering).</font></p>
<p><font size="1">By law, all new flues, for all types of fuels, built since the
introduction of the 1965 Building Regulations, must have been fitted with an
inner lining to protect the chimney structure from the harmful and corrosive
effects of flue gases. A properly designed and installed flue lining improves
flue performance and therefore fuel economy. </font></p>
<p><font size="1">This is particularly the case with modern boilers and appliances
which discharge at low flue gas temperature. This principal has been understood
since Roman times so that even prior to 1965, most flues were lined with a sand-based
rendering (or parging) that decayed quite rapidly due to the condensation from
the cooling flue gases thus exposing the original stack structure, usually porous,
to acidic decay. </font></p>
<p><font size="1">The inevitable results over the years are increased
fuel consumption; malodorous stains on chimney outer surfaces; deterioration
of the structure leading to sometimes fatal toxic smoke/fume escape and a weakening
of the entire chimney structure, especially where unsupported above the roofline.
Finally, deposits remain inaccessibly trapped in corroded mortar joints and
brickwork, impossible to remove by the most efficient chimney sweeping, leading
to chimney fires which present a serious risk to the entire building structure.</font></p>
