Temp here is like 5-10C all winter, 10-15 C autumn and spring and up to about 26 C in summer (30 is RARE but happens) (south coast of ireland)

I knew Ireland is known as the Green Island but like this? How do I find a work in this tropical paradise?

(The temperature here is 5°C +/- 25°C. Brrrr...)

On the insulation: It was once popular to do foam insulation of old houses here. Holes were drilled in walls, ceilings and floor and foam injected.
