What a great day to demonstrate the effectiveness of an insulated conservatory roof. The media are calling it "Furnace Friday" - the hottest day of the year, decade, since records began!? We will find out later.
At lunchtime we thought we would try a little experiment and placed a thermometer in a conservatory with an insulated room and reached 25 C or 75 F quite warm but not bad considering the 35 C outside.
Then we placed the same thermostat in the conservatory with a traditional roof. This is why we say it is cooler in the summer and warmer in the winter! It went off the scale above 50 C and above 120 F
