Bah, heating humbug!

I've just had my flat secondary-glazed (after spending a year unsuccessfully trying to talk the residents' association into letting me double-glaze the flat before the upcoming winter). I've spent over a thousand pounds on trying to stem the haemorrhaging of heat from my lounge—in addition to the secondary glazing, I've nailed slats of wood over the gaps around the edges of the juliet balcony doors, I've put brush draught excluders under the lounge and kitchen doors, I've put foam insulation around the opening panes of my windows, I've put secondary glazing film down on the windows of the juliet balcony door; and the place is still I-feel-like-an-old-granny-with-this-blanket-over-my-knees cold from the knees down.

I'm rather narked at this... but not very surprised. This place is appallingly shoddily constructed. What narks me is that my parents' place is roughly the same age (two years old than me), but was built properly: with double-glazing from the word go, and cavity wall insulation, and so forth. The difference is that their place was built by the people who wanted to live in it; this place was probably built to be let from the word go.

I'm not quite completely at a loss for how to try and warm my place further: my father suggested a fan heater set to blow air (but not heat it), to mix up the layered air; I suggested velcroing the curtains to the windowsill to stop the cold air sinking to floor level and escaping below the curtains; and also putting secondary glazing film back on my non-opening panes, so the glass secondary glazing becomes in effect tertiary glazing; but I'm still rather narked that the secondary glazing has had so little effect, for all it's cost me.
