Hi My garage is built on the side of the house and abuts to the garage next
door so the only 2 walls that are exposed are the back wall with a door and
window and the front which is a metal up and over door. I got a digital
thermometer which has a remote sensor and have noticed that the temp in the
garage is always about 6 - 7 degrees C higher than outside. Just now the
garage is 4.6 C and my greenhouse (unheated) is -2.5 C and because I always
feel cold the house is 22 C
My kitchen and hall and stairs are next to the garage so I assume that heat
is going through the wall.
For reasons that I won't go into, I cannot get my cavity walls insulated,
except by paying loads of money so I thought of lining the garage wall that
joins the house with sheets of 8ft by 4 ft polystyrene
Because the garage was built after the house was built the inside of the
garage wall next to the house is harrowed (is that the correct term, little
white stones) and the other walls made with breeze block and the roof is
tiled to match the house.
So how much less heat would be stopped from coming through the wall? I am
not bothered about the other walls as it is my house I want to stop heat
escaping from not keeping the garage warm.
So does anyone think it would be worth while?
And if the cost of gas and electric keep going up it might be worth while
getting the cavity walls done in the future.
