Energy Efficiency for Hardie Siding in Houston TX with Tyvek ThermaWrap

Energy Efficiency for Hardie Siding with Tyvek ThermaWrap

Southeast Houston TX homeowners often remove their old siding and install James Hardie Siding. This is a great decision for the longevity that fiber cement offers. Although often overlooked by most siding contractors, is what can be done before the new HardiPlank Siding is installed to improve the energy efficiency of the home. By adding a reflective energy efficient vapor barrier such as Dupont Tyvek ThermaWrap, this will help in utility bills with it’s added increased R and reflective values. Below I explain and provide some suggestions.

Your Texas home exterior walls can account for 40-70% of the solar heat gain and/or loss of your home. This varies depending on many factors such as the amount of sun exposure to walls, shade and the type of building materials your home was built with. Often I notice a job sign of a contractor doing a siding job and I see no roles of the Tyvek product delivered to the jobsite. When the siding is removed and there is no extra insulation existing with any level of R-Value such as Home Wrap being installed on the home, this is the perfect opportunity to install the Tyvek product while the siding is off and being replaced.

The Perfect Time to Install

Tyvek Thermawrap Reduce Texas Energy - Bills How It WorksSomething to think about, when you have your old siding removed, this is the best time to improve the energy efficiency of your Texas home, don’t you say? I would think that the immediate answer would be yes! When you have your old siding removed, this is absolutely the perfect time to install Dupont Tyvek ThermaWrap.

What this product will do for your Texas home is to push the unwanted HEAT Back Out of your home in the Texas Summertime and push the HEAT back INTO your home (prevent it from escaping) in the Texas wintertime. This in turn will save you money year round and reduce your Texas utility bills every month by having your Heat/AC unit run less now that your home is more energy efficient because the Tyvek ThermaWrap is stopping much of the heat gain/loss!

Energy Efficiency Performance under Your Hardie Siding 

Tyvek ThermaWrap is a low emissivity (Low-E), metallized weather barrier that will actually increase the effective and total R-value of any wall systems, to help improve energy efficiency in our Texas homes. DuPont Tyvek ThermaWrap is made with a metallized, low-emission (low-e) surface that reflects solar radiation away from our Houston Texas metro area homes. Cold weather in Texas, this will help stop radiant heat transfer and loss from within the home.

In the Texas summer weather, Tyvek ThermaWrap do the opposite by reflecting warm air back out and away from our Texas homes, to help improve air-conditioning (A/C) efficiency. In all of our Texas seasons, that can help make our homes much more comfortable, more energy efficient, and less costly to operate. No more Hot and Cold rooms and the home has more of an even temperature.

R-2 Plus Helping Block Air Infiltration and Exfiltration

ThermaWrap has the ability to help increase the effective R-Value of a wall, Tyvek ThermaWrap is also an excellent vapor permeable air and water barrier, like all Tyvek materials. The low-e surface changes the dynamics of radiant heat flow across the entire wall system.

Nearly two-thirds of the total heat lost or gained is through our Texas homes occurs through radiant heat flow. Tyvek ThermaWrap addresses this by helping to dramatically improve the effective R-value (resistance Value) of the wall system. This is highly effective at reducing heat gain when the weather turns hot here in Southeast Texas for over 6 months. Tyvek ThermaWrap is ideal for our Southeast Texas weather.

Radiant Heat

Radiant Heat flow occurs when heat is transferred from a warmer object to a cooler one by electromagnetic waves and natural heat flow. These waves do not need to pass through air and they do not require any contact between the two materials. They simply cross empty space in exactly the same way as the heat of the sun, which
can be felt on cold days. Tyvek ThermaWrap incorporates a low-e, metallic surface that changes the radiant heat flow dynamics of the entire wall system. In winter, it reflects and or pushes radiant heat back into the wall system. Texas summer time,
ThermaWrap reflects the outside solar radiation away from the wall system, to reduce unwanted heat gain into our Texas homes in southeast TX. The total overall effect is an overall total increase in the effective R-value to the entire wall system.

When installed, Tyvek ThermaWrap adds an effective R-value (thermal resistance) equal to R-2 (R- Value). In Texas homes this can help reduce energy usage and costs for heating and cooling systems, year-round. This is a huge plus for southeast Texas Homeowners in the Houston, Spring The Woodlands metro area.
