Pass ...

Our old porch gets mega hot in the afternoons, never thought about any issues. It would be impossible to do as you intend, since no cavity walls and the porch is directly under the floor of the upstairs small box room. I suppose fitting a awning is not a way out in this case? Sun shade and shelter at one fell swoop. Brian

Ours is chalet bungalow construction so the *porch* is tucked under the roof overhang.

To fit the ceiling vent, I'll have to get rid of the carpet offcuts stored up there!

Is this "Don't know!", or "not Fail ..." ?

What the OP needs is a porch, in front of the closed in porch. This will shade the new, closed-in porch from the sun. It will also do the work of a traditional porch - providing shelter for visitors whilst they wait for the door to be opened.

Hmmm. I think these houses in Andover are of timber-framed construction

I don't know if it matter but brick vents and the like seem likely to reduce the insulating effect of the porch in the winter.

I may have misunderstood what the porch is like but could you fasten the outer door open or is the inside liable to damage from rain etc?

Indeed. I suppose closing off the ceiling vent would minimise this.

As built, the front door was under a canopy formed by the roof overhang. We have fitted plastic doors/windows throughout and now further enclosed the entrance with a pair of double glazed French doors in an L shaped housing. I plan to arrange posts and door latches eventually. Last job was to cut and fit Coconut matting. This would be at risk if the doors were left open.

Not sure what the relationship is between the brick corner and the timber frame of the house but I assume the brick cavity is uninsulated to allow the hot air to vent and also has a way of dealing with any condensation?

Could you vent it directly into the house e.g. vents either side/ above/ below of the door? Could have the benefit of using the excess heat to add a bit of heat to he hall (although in the height of summer that may not be desirable :)) and also warm the porch a bit from the heat of the house (again may not be desirable).

This particular timber frame construction is from plywood sheeted weather proofed studwork panels. Glass fibre insulation is fitted between the studs and plaster board nailed on later. (everything is in

Not likely to be much of an issue during the heating season as we did not notice a significant problem before the Sun came out in the run up to the Wimbledon rainy season:-)

You could add heat-reducing film to the glass. It made a big difference to our west-facing porch. Search for SSAF.
