We had an extension built earlier this year. The insulation is amazing and spending time in that part of the house is a toasty joyfest.
The rest of the house is cold. And it’s not even winter yet. **Which insulation option should we choose? **Here is some extra info:
- The outside of the house has brick cladding in parts and pebble dash on others. Although it’s detached, it fits in with the style of other houses in the estate so we’re hesitant about external insulation.
- During the extension project we saw inside the walls. There is a cavity which has a fairly thin piece of polystyrene in the middle (house built in early 1990s). This doesn’t fill the space so I wonder if pumping into it is an option.
- Internal insulation seems like a runner. The only hesitation is that we would lose space.
Bonus question about internal insulation: the bathroom and en suite have relatively narrow walls/windows to the outside. I mean, they are rectangular rooms where the long side is an internal wall. Is it worth dry-lining the narrow walls? My hesitation there is the upheaval it will cause because the walls in question have toilets up against them.
