Finishing

Fitting skirting

It is advisable to fit some foam strip or 
sealant around the port opening before 
fitting the skirting. This will provide an 
air-tight seal between the wall and the 
skirting and reduce the possibility of 
any whistling or other noises that may 
occur due to air passing gaps behind the 
skirting.
•  Fix the foam strip to the wall around 

the opening. 

Choose a strip thickness that will just 
compress behind the skirting when 
fitted.

•  Fit the skirting.
