Proper Insulation Is Very Important For Energy Efficiency 

Insulation is measured by R value (resistance to heat flow).  The higher the number the better.  Proper insulation is one of the best energy investments for your home.  As much as 42% of your home’s energy loss is through the attic.  This makes your heat and air conditioning unit have to work harder to maintain a comfortable temperature in your home.    Having a home that’s been well insulated and sealed can save most homeowners as much as 20% on their heating and cooling costs.


There are Several Options for Insulating Your Home 

We are happy to provide input on the best type of insulation for your home and budget.

 

Attic Insulation

Fiberglass blown insulation has the benefit over rolled insulation since it does not leave gaps in which heat or cool can escape.    This provides an uninterrupted blanket for your home.  A few years ago, 6” of insulation was considered to be adequate, but in our climate zone R38 (14” of attic insulation) is recommended.

Open Cell Foam Insulation

Significant benefit can be achieved by foaming knee walls.  A knee wall is any wall where one side of a wall is an interior wall and the other side of the wall is attic, like a vaulted ceiling.    The interior wall can reach temperatures close to 130 degrees on very hot summer days.  Foaming these knee walls provides the kind of resistance to heat that can significantly improve the comfort and efficiency of your home.  It also provides air infiltration sealing.  Open cell foam is also very effective where there are dropped ceilings that have similar energy issues as knee walls.

Foam the Roof Line

 It is becoming increasingly popular to foam the roof line.  While this can be very effective, a professional needs to give guidance as this can be very expensive on retrofit homes and can introduce moisture issues and safety concerns if not done properly.

Closed Cell Foam Insulation for Crawl Spaces  

Foaming the perimeter of a crawl space or the floor can significantly improve the comfort and efficiency of your home.  This effectively reduces dust, pollutants, and moisture from entering the home while creating an area of “conditioned space” under the house.  This make the floors more comfortable for bare feet and can keep pipes from freezing under the house in the winter.

Drill and Fill Fiberglass Exterior Wall Insulation

Exterior walls can have insulation added on retrofit homes by drilling holes along the interior of the wall and blowing fiberglass insulation into the holes under pressure. 

 


Insulation -- Blown or Foam

What are knee walls, and why is

insulating them so important?


What is a knee wall anyway?!  Think about having an interior wall in your home and the other side of that wall is a HOT attic that can reach 130 degrees in the summer.  Frequently we find these by vaulted ceilings or walk in attics.  The only thing separating you from all that heat is drywall and ineffective insulation.   Most knee walls have batt insulation on the attic wall.  Batt insulation was meant to function in a closed sided box like an exterior wall.  Applied to a knee wall, it's like having only 2" of insulation separating you and your loved ones from that sweltering 130 degrees!  

There are several solutions, but one of the most effective, is foaming that knee wall with about 5.5" of open cell foam.  This can make a major difference in the comfort level of a room!

Don't be Fooled by Unskilled or Dishonest Contractors!

Be sure you get the right amount of insulation.  Dishonest or unskilled companies will blow insulation to 14" but not all 14" are the same.  

If the company "fluffs" the insulation, it will settle and you will not get the R Value that you paid for.  Blown insulation should always be blown by the bag count to assure that you are receiving the proper amount of insulation!
