JM Spider® custom insulation is installed with little to no waste. JM Spider Custom Insulation is made of greater than 98% fiber glass - an abundant and renewable resource. And at least 25% of the glass is made of recycled glass content. It is made with certified JM Formaldehyde-free fiber glass, which improves indoor air quality by reducing overall exposure to formaldehyde. It also offers a high R-value per inch which provides superior resistance to heat transfer, helping to reduce energy consumption and energy bills.
