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.
