Whether to insulate a house inside or outside is one of the most important choices that builders and homeowners face. Internal insulation can save money but reduces usable space and is susceptible to condensation. External insulation minimises cold bridging and is more resilient against water and the elements. But which is the best option?

It’s a good idea to insulate your home’s walls with either blanket or loose-fill insulation, depending on the type of home you have. It’s best to apply the insulation during the build process, but older homes can also benefit from it too. It’s vital to ensure the correct type of insulation is used, as it can significantly impact the performance and life of your home’s structure.

Builders often insulate the exterior walls of a new home to keep heat in during winter. However, they don’t usually insulate interior walls unless they’re between heated and unheated spaces. The government sets minimum insulation requirements that builders must follow. For details on Insulated Render Systems, contact https://www.apsltdbristol.co.uk/external-wall-insulation/

If you’re building a new home, consider using advanced wall framing techniques like structural insulated panels and insulating concrete blocks which have insulation built in to them. This helps to improve the whole-wall R-value and reduces thermal bridging through wood studs. Also, if your home is timber framed, you can insulate the walls by applying a layer of blown-in insulation between the joists. This method provides a seamless, continuous layer of insulation and greatly improves the overall R-value of your house’s solid walls.
