Our goal at Centerstone is to build a better house. We
are constantly exploring cutting edge research and advancements
in residential construction technology. Centerstone analyzes
all potential advancements based on our experience and
local conditions before incorporating the change into
our construction practices. Below is a brief description
of the building technology Centerstone currently incorporates
into each house. Feel free to call at (303) 778-8745 or
email Don if
you have any questions.

Centerstone
homes are designed as an integrated, holistic system
with respect to building technology. From foundation
to roof, these sub-systems work together towards
a well crafted, comfortable and durable home.
This integrated approach begins with an understanding
of Colorado's climate and geographical conditions.
Denver is considered in the "cold" climate
zone, while some mountain regions fall within the
"very cold" zone based on hygro-thermal
regions. These regions take into account both temperature
ranges and precipitation. To learn more about Hygro-Thermal
regions, download a free copy of "Houses
that Work II" published by NREL's Building
America program. In addition to climate, many local
Colorado soils are expansive and demand special
attention with respect to foundations. Fire
is also a potential problem for houses along the
urban/wildland interface and other wild areas in
Colorado. To learn more about strategies that protect
homes from wildfires, visit the Wildland
Fire page of South Metro Fire Rescue.

HVAC or Heating, Venting, and Air Conditioning
are primarily understood as creating a comfortable climate
for occupants. However, the HVAC system also plays an
important roll in building durability and longevity by
exhausting moist air out of the building before it can
build up within the wall or roof system. Centerstone's
Energy Star Certified homes combine the latest in HVAC
technology to achieve maximum occupant comfort at minimum
energy consumption. These systems are also designed to
work in coordination with vapor barriers and other envelope
components.

Energy Star upgrade includes:
- High Efficiency Furnaces
- Sealed Duct System
- Manual "J" & manual
"D" engineering of system
- 13 Seer A.C.
- Setback thermostats
- Advanced insulation and sealed
envelope package.

A
home's roof plays a vital role in keeping the weather
out and keeping conditioned air in. The roof can also
provide shading and protection for the walls and foundation.
And reduce heat gain for the entire home. A strategy of
Centerstone is to provide an engineered energy truss where
practical. Not only do engineered energy trusses provide
longer spans with less material. They allow for full depth
insulation all the way to the exterior of the wall. A
Deeper truss also provides space for venting from soffit
to ridge. Venting of the attic above the insulation is
a key component to keeping the roof cool, extending the
life of roofing, reducing heat gain, and minimizing moisture
build up in the attic.
Centerstone
maximizes the benefits of engineered energy trusses with
the addition of an advanced attic venting system. This
system is composed of continuous soffit venting combined
with air scutes as needed and a continuous ridge vent.
2 foot wide overhangs are utilized to shade and protect
the exterior walls when the home's style allows. All Centerstone
homes come complete with gutters and downspouts with extensions.
Gutters are a key strategy for keeping water away from
the home's foundation. Downspouts should extend at least
5 feet from the foundation wall.
No
matter how well constructed a home's wall assembly, water
will enter somehow. Centerstone's typical wall section
is designed to minimize water infiltration with state
of the art flashing, building paper and exterior finishes.
However, our walls are also designed to remove water when
it does enter the system. Unlike most builders, Centerstone
uses CDX plywood instead of OSB on exterior walls. Combined
with building paper lapped "shingle style" and
a breathable exterior finish our walls dry to the exterior
as is recommended by the Building
Sciences Corporation and other experts. To read more
about moisture download their research paper "Insulation,
Sheathings and Vapor Diffusion Retarders" (BSC
2003). Our commitment to quality construction is further
demonstrated by the fact that Centerstone homes have 2x6
exterior walls usually insulated to R-21. These walls
are highly sealed to prevent air infiltration according
to Energy Star guidelines. And because the wall dries
to the outside, Centerstone provides a vapor retarder
on the inside to prevent moist warm interior air (in winter)
from condensing inside the wall.
The Denver Metro area has many soil types,
some are moderately to highly expansive. Each home Centerstone
builds has a foundation specifically engineered to meet
the demands of the site's soil conditions. Many of our
projects feature caisson footings to bedrock. Keeping
the foundation as dry as possible is a critical part of
quality construction. Unlike most builders Centerstone
provides a double foundation drain system. 4" drain
tile is placed on both the inside and outside of most
Centerstone foundation walls. The exterior drain tile
is tied directly into area well drains. Drain tile connects
to a sump pit which is designed to accept a sump pump
should the need arise. This drainage strategy combined
with a positive grade away from the house, gutters, downspout
extensions, and foundation wall damp proofing help make
Centerstone's foundation system far superior to standard
practice.
