What does insulation really do?

A well-insulated home, particularly one that is insulated with fiber glass insulation, is one of the most cost-effective ways of saving energy and reducing heating and cooling bills while adding to the thermal and acoustical comfort of a home.

Why do I need a professional to install my insulation?

To do the job properly is the short answer. The professional will install the correct amount of insulation you need and avoid the common mistakes that cause air filtration or making the house "too tight". Improperly installed insulation can cause you to spend too much on heating/cooling or even cause structural damage to the house due to humidity or moisture build up. The professional will do the job right the first time.

What is R-Value?

Insulation is identified and labeled by R-Value. "R" stands for resistance to heat flow. The higher the R-Value, the greater the insulation power.

Does a company have to be lead certified for certain jobs?

Yes, the new EPA rule states that on or after April 22, 2010, firms working in pre-1978 homes and child occupied facilities must be certified and use lead-safe practices during renovations. Boak & Sons has obtained this certification and will follow EPA lead-safe guidelines for jobs that require such treatment.
