Loft space ventilation for these hot summer days
Hi,
as usual it is like a sauna in the loft. There is a ventilator grille on one gable end, but I guess in ventilation terms this is the sound of one hand clapping. Any reason I shouldn't put a 'hit and miss' ventilator in the other gable end to encourage a free flow of air along the head of the 'T' shaped loft space? The plan is to leave it open in summer to get a flow of cooling air through, and shut it in the winter to keep any daytime heat in. If I was feeling fancy I guess I could even put an extractor fan coupled to a thermostat - although half the time it might be blowing agaist the wind and not achieving much. Plan 43A involves roof vents and greenhouse type auto vents; however life if probably too short :-) Cheers Dave R -- |
Loft space ventilation for these hot summer days
Hi Dave
I thought it was impossible to have too much ventilation in a roof above the insulation. In Winter you want to blow out any warm moisture laden that goes through the insulation before it has a chance to condense on the wood work in the loft. in the perfect world ( i.e. not my house) you should have eve vents as well as the vents in the gable cheers ian |

If the heat has got into the loft it's pretty much wasted anyway..... I can see no problem with what you propose, but I think it will make no great difference to the temp inside the loft. The area of ventilation will just be too small. -- Chris French, Leeds |
