7. PERFORMANCE, DESIGN<br />
AND SITE PRACTICE<br />
7.1 Durability<br />
All dense bricks are classed as frost resistant and exhibit excellent freeze thaw characteristics. This has been<br />
confirmed by independent testing.<br />
For further information refer to our Brick <strong>Technical</strong> Bulletin BTB 6 – Durability.<br />
Although not directly comparable <strong>Edenhall</strong> bricks can be considered to be at least equivalent to a clay F1/S1<br />
grade brick.<br />
Lightweight coursing bricks are only recommended for use in internal walls above dpc.<br />
The table on the next page, which is extracted from Table 15 of PD 6697: 2010, shows the recommended<br />
brick strengths and mortar designations for specific locations. (Also Ref. BTB 4 – Mortars for Concrete<br />
Masonry Products).<br />
(Note: This Standard has superseded BS 5628: Part 3 which is still in common circulation. For more<br />
comprehensive information please consult the Standard. Further note that the strength grades given are<br />
those which apply for <strong>Edenhall</strong> bricks.)<br />
