Internal Wall Thermal Insulation

Internal wall insulation is a great solution for those looking to improve the thermal properties of solid walls and reduce the cost of energy bills.

That said, it can be disruptive as it requires the removal and refitting of items such as radiators and kitchen units. External wall insulation is a common alternative for solid walls, which doesn't require the same level of disruption.

What is The Best Insulation For Internal Walls?

Which insulation is best for internal walls depends on your requirements and budget. Some of the most popular types include boards, slabs and rolls. Roll is the most efficient solution, but also the most expensive, whereas boards and slabs are more affordable.
