When upgrading your Attic insulation it is very important to lag all water pipes in your roof space and were necessary increase ventilation.
When upgrading your attic insulation your roof-space becomes colder especially in winter months! Lagging water pipes in your loft can help prevent them from freezing during the colder weather.
Increasing ventilation will moderate the temperature in an attic or roof space. By preventing a roof space from getting too hot or too cold you reduce the build-up of moisture levels. Allowing the air in a property to circulate keeps the air fresh and reduces the risk of condensation!
When you Insulate always Ventilate!
