insulation

Building insulation is any object in a building used as insulation for thermal management. While the majority of insulation in buildings is for thermal purposes, the term also applies to acoustic insulation, fire insulation, and impact insulation (e.g. for vibrations caused by industrial applications). Often an insulation material will be chosen for its ability to perform several of these functions at once.
Insulation is an important economic and environmental investment for buildings. By installing insulation, building use less energy for heating and cooling and occupants experience less thermal variability. Retrofitting buildings with further insulation is an important climate change mitigation tactic, especially in geographies where energy production is carbon-intensive. Local and national governments and utilities often have a mix of incentives and regulations to encourage insulation efforts on new and renovated buildings as part of efficiency programs in order to reduce grid energy use and it's related environmental impacts and infrastructure costs.

    Gas pipe under loft insulation.

    The copper gas pipe to my boiler in the loft runs between joists and sits on the plasterboard. I understand that it should not be covered by insulation. Why? Is it satisfactory to create a dome over the pipe with upside down guttering and then put fibreglass insulation over the top please?

    Foam insulation wrap question

    Hi everyone, I have bare pipes under the kitchen sink and also in a cupboard next to my bathroom. Is it a good idea to put foam wrap on them and if so should the wrap be on both hot and cold water pipes or just the hot water pipes? Thank you any advice would be appreciated.

    Is this pipe lagging safe to remove?

    Ideally, I want to cut these redundant pipes out. I’m pretty sure this is hair felt insulation but I’m a sparky by trade so not familiar with pipe lagging. I do know pipe lagging often contained asbestos and as the house was built in 1890 and sporadically worked on ever since… could do with some...
