We have now lived here for more than ten years. Each year we've done something which has improved the energy efficiency of our home, including this year when we inexpensively added more insulation to the top floor of our home. The result is that this winter our home is again a little warmer and also more energy efficient so more economical than it was before.
This year's improvement was quite minor: We added insulation to the ceiling above the top floor landing and staircase. This results in the first floor landing and ground floor entrance hall being better insulated than they were before. This job actually began in the first winter that we lived here when I quickly added some thin insulation panels to this area after seeing our first winter fuel bill. It continued a few years later when I doubled the thickness of that insulation but then remained as an unfinished job until the beginning of this year when we began the last part of it, stretched out over months because of other commitments, beginning by adding yet more insulation to reach a total thickness of about 10 cm, covering this with reflective and damp proof foil and finally hiding that with plasterboard (aka gipsplaten, gypsum board, sheetrock), sealant to fill the gaps and applying some paint. Actually, the job is still not quite finished. I need to paint again.
Anyway the process was simple and can be summed up in one photo:
It's been five years since I last wrote about insulating our home but that's not five years of doing nothing. Another job which was completed a couple of years ago was taking apart the lower parts of the front and back walls on the ground floor of our home. I had long suspected that there was not much insulation inside these walls, and was pleasantly surprised to find that they were better constructed than I had expected. In total there was 4 cm of glass wool plus another 3 cm of polystyrene solid insulation bonded to an asbestos sheet which provides weather protection on the outside of the house to a height of about half a metre (we don't have any other asbestos so far as I know, except a fireproof panel on the door to the room with the central heating).
Neither of these jobs cost much to do. The results of them are difficult to quantify, but thicker insulation and reflective materials to keep infra red energy within the house ought to be expected to bring improvements. We notice that even on cold nights the wall behind the radiator now feels warm rather than feeling cold so it seems that the reflection within the wall is helping. Even more obvious is that we keep snow or frost on our roof a lot longer than any of our neighbours do. Our immediate neighbour's home, featured in some of our photos because it's closest by, is far from the worst in this regard.
Neither of these two jobs was expensive to do. The materials (reflective foil, insulation, tape, sealant, glue, screws) are cheap. It required a bit of planning and took quite a few hours, but it's a reasonable DIY job.
A less inexpensive job
Last year we also had a problem with one of our windows. The seal had broken on an older double glazed unit in our front room, dating from the 1970s, and we arranged for this to be replaced by a new triple glazed unit:
|The old glass looked misted up all the time because moisture was caught between the two panes. This is not a rainy day photo even though it looks like one.|
|The new triple-glazed HR++ panel before installation. It only covers a small percentage of our total glass area but at least this small percentage will perform far better than before.|
Measurements made with an infra-red thermometer show that when the outside temperature is -2 C and the inside temperature of our home is 17.5 C, the inside of the older double glazed panel is 9 C while the inside of the new triple glazed panel alongside is 14 C. Clearly heat loss with be much smaller through the triple glazed panel.
Our current plan is to replace other double glazed units with triple glazing as they fail. When we bought our home there was single glazing upstairs but we had that replaced some years ago.
Better insulation = a more pleasant home
Better insulation means a more comfortable home, less energy consumption, a lower carbon footprint, and lower bills. What's not to like about any of that ? Many effective treatments can be made
