All newer homes have insulation installed to make a house more comfortable and efficient. Insulation works by slowing the transfer of heat, both from the outside in the summer and from the inside in the winter. Everyone knows that insulation is important but what is generally not known is how important proper installation of insulation is for optimum performance.
Insulation needs to be installed evenly and completely, with no gaps, compression or areas without insulation – like possibly in the corner of a stud bay. Insulation also has to touch the air barrier for it to work; insulation not touching the air barrier is like having your coat open on a cold day – it doesn’t work.
