If you trying to deduct an energy credit then see below. If not then please provide more details.
Homeowners can be eligible for a tax credit of up to $500 or 10% of qualified energy efficiency improvements, such as insulation. Is that what you are trying to deduct?
I suggest you call the company for a breakdown or compute the actual cost yourself by calling to price the type that you received by the area space. Keep your receipt to show total cost and how you determined the deductible portion.
