Welcome to a New Chapel Ridge Family

 

 

 

 

Signing the contract with the homeowners of this Chapel Ridge home happened in record time – 10 days from the day we met to the day the contract was signed.  I had been working with the homeowners for a week trying to find the perfect home and after determining that too many sacrifices would be made with everything we looked at, Rod and Susan decided to design their own home and built it exactly the way they wanted.  They found a floor plan that we had built before and made a couple modifications – 3-car garage, large bonus room and covered back deck for Rod and a large walk-in storage room and loft converted to craft room for Susan. Even with the changes we were able to finish the home in just about 5 months without going over budget.

“We never wanted to build a house, heard too many stories of problems with the process, but build we did and we are so happy with our decision.  Absolute Construction, Nelu and Lisa Skumpija and their vendors and sub-contractorsgave us a beautiful and well constructed house.  They involved us in each step of the process, gave us a list of vendors and a timetable for meeting deadlines for their product lines, and kept us apprised of costs so we stayed in

budget and within the parameters set for completion.  Nelu listened to our suggestions for changes and accommodated as many of these ideas as was practical and suggested a few of his own. The end result is more than a quality, Energy Star efficient house; it is our home, unique to us and our needs.   As we live in it we hope to take as good of care of it as Absolute Construction did in building it.

Thank you Nelu and Lisa and all your wonderful workers for making our dream come true.”

Another Silk Hope Home Completed!

We had the joy of working with very creative homeowners when building this beautiful home in the Silk

Hope area. We had been working with the homeowners for over a year in detailing the plans, specifications and allowances.  The homeowners were out of state which added a bit of a challenge, but one we’ve worked through on many occasions.  See full photo album of this Country Retreat in our Gallery.

“We selected Absolute Construction as our builder for a variety of reasons, but after visiting the homes that Nelu built, we were sold! The craftsmanship, style and attention to detail were exactly what we were looking for and our new home can now be added to the list of beautiful homes in Chatham County.

Living out of state for the entire building process could have been a significant disadvantage and we were concerned about it at the beginning. However, Lisa and Nelu were diligent about keeping us informed of the construction progress and expenses. We received electronic photos regularly which thrilled us to no end. When we were able to visit, Nelu arranged meetings with contractors according to our schedules and they were generous with their time and attention to us. 

Nelu and Lisa are a complete package and an effective team throughout the process. Lisa’s attention to detail in all things financial is something that cannot be overlooked. She acted as a liaison with the vendors, intervening on our behalf when necessary and settling any potential conflicts. They are both true to their word and honored all commitments to us. 

Our new home is really a life–long dream come true and we are so happy with the end product. We believe that Lisa and Nelu were the main reason that we had an overall fantastic experience. Their flexibility, integrity and skill make them a solid and smart choice for anyone considering building a home.”

Foam Insulation – The Hidden Super Construction Material

Current conventional insulation, fiberglass and cellulose, are readily available in rolls or blown forms. While, conventional insulation provides some form of resistance to heat transfer, its overall effectiveness needs significant improvement.  Approximately 40 years ago, foam insulation was first introduced into the construction industry. The initial introduction was plagued with problems, off gas of formaldehyde and VOCs, material shrinkage, and sensitivity to off gassing chemical and VOCs. However, through years of improvements in research and development, raw material quality and installation equipment, the development of open cell and closed cell foam have significantly improve thus greatly improving the ability to insulate a home/building.

When addressing heat transfer into and out of a housing/building structure, one needs to address all three forms of heat transfer:

  1. Conduction – conduction is the transfer of heat through a solid member such as studs in your walls and roof, sheathings, etc… The resistance to conductive heat transfer (R-values) is the current standards used for by the industry to measure the effectiveness of the insulation.
  2. Convection – convection is the transfer of heat through a viscous material such as air. Regardless of the R-values, if the insulation material allows air to transfer/move through it, its overall insulation effective performance is significantly diminished. How effectively a structure have been built to resist convective heat transfer can be measured through the use of “blow door testing”
  3. Radiant  – radiant heat transfer is the transfer of heat through energy waves. For example, the roof from a conventionally vented attic absorbs heat energy from the sun and heats up to temperature in excess of 160 degree F. The heat is then transferred through the roof sheathing and studs through conductive heat transfer and then re-radiate inward into the attic. The result is an attic with temperature in excess of 130 degree F or more. While reflective sheathings and reflective foil claims to reduce the heat by 17 to 30%, a foam insulated attic will stop up to 95% of total heat transfer into the attic.

Why is R-value not a true representative example of insulation values?

In a conventionally insulated home, conductive heat transfers only accounts for about 10-20% of the total heat lost and gains. Convective heat lost can accounts for as much as 60% of the total heat lost and heat gains. In addition, radiant heat transfer (heat gains from the sun’s radiant energy) will account for the remaining 20-30%. Furthermore, the R-values of conventional insulations are tested in a laboratory setting and does not take real life conditions into account.  Studies have shown that fiber glass insulation installed where air transfer are allow to circulate through it, will performed only at 30-50% of the claimed insulation values (ie. An R 13 in the exterior walls is only as effective as an R-5 to R-7 in actual performance value.) It is this author’s opinion that the department of Insurance and Department of Energy reconsider the current and obsolete manor for determining the true insulated values of an insulation  by taken into account not just resistance to conductive heat transfer (R-values), but also heat lost and gain through convective and radiant heat transfer. Oak Ridge National Laboratory (ORNL) conducted an experiment (*) to determine the efficiency of a roof assembly insulated with low density, loose-fill fiberglass insulation and discovered that up to 50% of the heat loss occurred as a result of convection; air circulation through the insulation. This result showed that the air-permeable insulation had loss its anticipated thermal performance level by half and that convective heat transfer had a significant negative impact on insulation performance.

Closed Cell (Medium Density) Foam vs Open Cell (Low Density) Foam.

There currently exist two types of foam being use in residential applications: Open cell – Low density foam, and Closed Cell – Medium density foam. There are positive and negative to both products:

Open Cell Positives:

  • High thermal efficiency, performed at 98% of prescriptive R-values
  • Lower cost – approximately 50% the cost of closed cell foam for same prescriptive R-values
  • Same thermal efficiency as closed cell at half the cost
  • Is a registered air barrier at 3.5” for most open cell foam
  • Cured in under 1 minute
  • Has zero off-gas
  • Does not create dust
  • When engineered with the HVAC system: provides for a healthy, energy efficient, low humidity, and comfortable indoor air quality
  • Adds toward building structure strength
  • Is a durable building material – certain manufactures will guarantee the product for the life of the structure
  • Excellent at suppressing audible noise
  • Has low environmental effects

 

Open Cell Negative:

  • Is not a vapor barrier, so in northern climate zones a vapor barrier (6 mil plastic) is required on the inside of the thermal envelope
  • Some open cell foam product will wick water, if this trait is high in a foam product, it could lead to water issues if house is not properly dried in (seek out hydrophobic foam products)
  • Requires significant trimming and has large quantity of waste

 Closed Cell Positive:

  • Higher R-values per inch when compared to conventional insulation and open cell foam.
  • Is a vapor barrier
  • Provide significant strength to building
  • Excellent at suppressing audible noise
  • Is a durable building material – certain manufactures will guarantee the product for the life of the structure
  • Does not create dust
  • Is a vapor and air barrier

Closed Cell Negative:

  • Extensive period of off-gas (up to 2 years)
  • Not recommended for people with sensitivity to chemicals, allergy, or have respiratory issues
  • VOCs
  • In North Carolina, the vapor barrier is placed on the wrong side of the building
  • Closed cell foam underneath roof can result in roof rot is roof leaks occur
  • Experienced company like Healthy Home Insulation, LLC who installed both open and closed cell foam has made it a practice to not utilized closed cell foam in residential application due to the health water damage liabilities.

Conclusion:

As a consumer, we can significant reduce utility cost for heating and cooling our new and existing homes by 50-70%. We can live in a home with superior indoor air quality, is quiet and comfortable. Foam insulation is the most energy efficient insulation product currently available in the market. The use of foam insulation should however, must be incorporated into the house as a system and not use just as a single building product. Correct sizing of the HVAC system(s) by an experience HVAC contractor or building engineer is strongly recommended and will provide for maximum energy efficiency, long-Gevity of the HVAC equipment, proper ventilation and dehumidification of indoor air quality, comfort and a healthy indoor air conditions. Foam insulation is one of the very few building product that can provide an immediate return on investment for new construction and has a ROI in existing retrofit projects in as little as two years.
