Internal Wall Insulation
Internal wall insulation can be used in both commercial and residential properties to improve indoor comfort and boost energy efficiency.
What is Internal Wall Insulation?
Internal wall insulation is the process of applying insulation to the inner face of exterior walls to increase the property’s thermal efficiency. Interior wall insulation boards are normally bonded or screwed to the walls and runs from the ground floor all the way up to the eaves level, where it reaches the roof insulation. Its aim is to provide a complete internal layer of insulation to keep the building warm.
Types of indoor wall insulation
- Rigid foam insulation boards (PIR) – It is a type of thermal insulation developed from polyurethane and is one of the most used material in construction that is primarily used for pitched walls, floors, and pitched roofs.
- Insulated plasterboard is a typical building material that consists of a single sheet of regular plasterboard or gypsum board sandwiched between two sheets of insulating material.
- Acoustic Roll is a Glass Mineral Wool roll with sound absorption and noise reduction properties that can be used in internal wall application Slab insulation is one of the most efficient ways to improve your home’s thermal quality while reducing sound transmission.
Benefits of Internal Wall Insulation
If you do not wish to lose a lot of room space, you can use thin insulation for internal walls. PIR Insulation board are available in variety of thicknesses to suit all types of walls for all projects.
Internal wall insulation cost is affordable although it costs more than cavity wall insulation, it’s usually cheaper than external insulation and in a long run it will save costs on energy consumption bills by preventing heat loss of your home.
The work can also be done room by room minimizing any disruption.
