Hi , my house is going to get exterior insulation ( rock wool ) & pebble dashed over the insulation , i have a vent at the back of the house & was wondering if i can let them cover this , the vent is above floor level & comes into the back of my kitchen units ,
so i don't know the purpose of it ,
the house was a steel house originally , & breeze blocked & pebble dashed over 30 years ago
