Use a thermal tube to wrap the joints and wrap the tube tightly with ethylene
tape.
Fix the wrapped pipelines vertically on the external wall with
duct through and pipe clamps, available at DIY-stores.
Fill the gaps in the holes made for the pipeline to prevent
rain-water from entering.
Lead the water drainage pipe to a suitable drainage point,
making sure that the water can flow through freely.
