Technicial Guidance Document F 2009

The latest version of  Technical Guidance Document F 2009 relating to Ventilation was published during the week. The document comes into effect in October year, although if one has applied for planning permission before 30th September 2010 and has the building substantially complete (meaning external walls complete) one can use the 2002 TGD F. The document is more informative to previous documents and provides better guidance in my opinion.

Many will question why bother making a dwelling air-tight when one is required to provide addtional backround ventilation where MVHR is not used. Definately something for another days debate.
