Our Valley roof loft space has four large air bricks at each of its ends. When a slight bit of breeze blows a cold draught rattles through the loft hatches and chills the whole house.
I understand that ventilation is needed to prevent rot in the roof beams but is it sensible to instal some adjustable air vents on the air bricks to restrict the flow a little?
Also what is the recommended depth of loft insulation at the mo? Can the new silver sheet style insulation be laid over fibreglass or does the fibreglass need removing first?
