Today we put up two extra layers of plastic sheeting on the underside of the corrugated roof. We wanted to reduce the heat losses of such a large “window”! being only a temporary construction, we use standard builders plastic sheeting which is not absolutely clear and only costs a few pence per metre.


Putting up two more layers will hopefully create some additional insulation effect especially during the Winter months. It does cut down on the light level (probably by a third) but it is such a large area (10m x 2m), it is still very bright.

Now we can install the return-path air ducting to remove the old hot air from the corridor and allow fresh cooler air in the bedrooms and lounge.
