Pitched roof insulation details.

Pitched roof actis products are suitable for pitched roofs providing the complete package combining breather membrane vapour control layer and insulation. As this requires fitting insulation above the rafters the roof covering will have to be removed in order to fit the insulation. When it comes to pitched roofs however adding a thick layer of insulation to the rafters can result in a depth of roof construction that may not suit every site meaning over rafter insulation sarking only is not a viable option. Ventilation vapour control and insulation to provide adequate ventilation and to avoid condensation in roof voids pitched roofs that have insulation at ceiling level should be ventilated to the outside air.

Fabrications with 3mm 10mm openings are acceptable. Another key advantage of specifying a pitched roof is the ability to provide a very high level of thermal performance in these roof types whether you re looking to insulate at joist ceiling level for a cold pitched roof or at rafter level if a living area within a warm roof construction is desired. Insulation is effective within the pitched roof but a strong fabric performance means the design and installation extends beyond the u value and thicknesses of celotex.
