| Insulation options for basements
Dependant Foundations has reviewed several different
options for improving the "R-values" of the traditional poured wall foundation.
This is a result of customers that are concerned about rising energy costs and in
anticipation of changes in energy codes. Below is an overview of estimates on heat loss and 3-ways to address it
Estimate of heat loss. It is
estimated that 30% of home heat loss occurs in the basement and that 80%
of the 30% is between "Grade" and the "Sill Plate"

| Traditionally most homeowners used their basements for storage and utility.
However an increasing number of homeowners are benefiting from using the
basement area as additional living space and recreation.
The second benefit is higher resale values and return on investment
[notably higher returns on walkout basements or basements featuring emergency
egress].

WHAT ARE THREE WAYS TO INCREASE THE BASEMENT
WALL "R-VALUES"?
Furring out walls "Traditional Construction"
- In the past, the most common method has been to use 2"x4" wood
construction to build out walls with vapor barrier, insulation, required
electrical, and drywall.
Exterior Foundation Insulation
- Builders and homeowner that have no immediate plans to finish out a
basement, but are still concerned about energy cost and "R-Values" will
often waterproof the foundation and then cover the below grade foundation
with insulation materials. There are several types of substrate
materials that offer a value between R-5 to R-10. Some of these
substrate materials also have drainage features that help keep water away from the
foundation and reduce the likelihood of potential leaking. The primary
disadvantage of these systems are that they are not suited for area where
brickledge is required [an area where thermal bridging will occur].
Dependant Foundations can provide a number of these options for customers.
