SAVE MONEY, instantly, on your energy bill.

House A - Good attic insulation - White frosted roof

House B - Poor attic insulation - spotty frost
On an early frosty morning, take a look at your roof and other roofs as you drive through your neighborhood.

Some roofs will be frost or snow covered and others will appears to have melted the frost away.


In our area of Coastal South Carolina, this is mainly due to heat escaping through the ceiling and into the attic because of poor ceiling insulation.  The escaping heat warms the roof shingles & melts the frost & snow.


Be friendly to your wallet. Your local Electric Company is charging more and more for the gas & electricity to heat your home.  When  your heat escapes through the ceiling, you spend more money to replace the lost heat.


An immediate and inexpensive solution to help you keep more of your money is to add attic insulation.


A confident DIY'er can tackle attic insulation as a fairly simple one day project.  If you'd rather hire someone, then use a licensed contractor or insulation company to help you.  (see our website www.strockenterprises.com for the 10 things to know before you hire someone to work on your home).

What are your choices for attic insulation?
You have several good choices for insulation in your attic.
Blown fiberglass - Quick, cost effective, good r-value if installed properly.
Blown cellulose - Same as above, but can compress quickly, especially in humid attics
Fiberglass batt - Good r-value, but more intensive labor required for proper install on existing attics.
Expanding foam insulation - Good energy savings with significant upfront cost and other drawbacks.
Recycled denim & water bottles - Newer "green" products.  I haven't used these yet.


With a little time & money, you can significantly reduce your energy bill.

Note:  The photos above were taken on 12/27/2010 at 8am.  Each roof is the Northern facing roof.  And, each house was built around 1950.  House A has had blown fiberglass installed in the attic within the last 8 years.  House B hasn't had any improvements within the past 10+ years.  The heavy frost seen of House A indicates that heat from the occupied space is not conducting into the attic because of insulation.  The melted frost seen on House B indicates that quite a bit of the heat from the occupied space is conducting through the ceiling and into the attic.  This raises the ambient air temperature in the attic, the roof framing & sheathing & shingles which causes the frost to melt.
