Item 2 of Table 3 (Maximum nominal internal diameter of pipes passing through fire separating element) now makes it clear that a uPVC pipe, up to 110mm in diameter, can pass through a wall or floor separating a dwellinghouse from an integral garage. The pipe should, however, still be fire stopped in accordance with paragraph 7.8. This would involve sealing around the pipe where it penetrates the wall or floor using a suitable material or a proprietary system as described in Paragraph 7.14.
