Pipe routing in timber frames/stud work
When installing Pipe-in-Pipe in timber frames,
the conduit must always be fixed against wall
studs or floor joists as follows:
• At the beginning and at the end of each
bend.
• In straights with at least 1 fixing every two
metres for PAL pipe-in-pipe.
• For PE-X pipe-in-pipe, fixings must be
provided every 0.6 m so that they can be
replaced. The pipes should not be drawn
completely straight between the connection
points. Soft curves give the inner tubes the
required expansion space, thereby reducing
expansion movements at the tube ends.
In addition to fixing, clamping must take place
so that any movements in the pipe network, for
instance due to rapid pressure changes, do not
cause disruptive noise or abrasion of the conduit.
Conduit fixing and clamping must take place us-

Protection Plate are recommended to protect
against nailing damage. To protect ducts from
sharp sheet edges when laying in a sheet metal
walls, LK Tube Protector can be used. Always in-
sulate potable water pipes from any underfloor
heating or hot tap water by placing the pipes
deep in the floor insulation. However, make sure
that the tapwater pipes are laid in compliance
with the requirements for laying to prevent dam-
age due to freezing
