week 25. insulation batts arrived this week. made from polyester fibre, they are rated 180mm R3.2 for ceiling and 100mm R2.2 for walls. we cut them with a handsaw to fit snugly between studs. crevices at the corners are stuffed with ribbons of insulation offcuts.
 |
| insulation batts for the ceiling are thicker than those for the walls, laid across the ceiling battens with staggered joints; note no gaps |
 |
wall insulation is fitted between studs; note: building wrap is trimmed around window and turned up before stapling to sides and gap between window frame and wall frame is sealed with expanding foam
 |
| wall insulation batts fit snugly between studs and between sill and bottom plate |
