Learn About the Unique and Energy Efficient Products that we use - Product #1: Roxul Insulation

To learn why we use Roxul Insulation (Stone Wool Insulation), here is the brief history and benefits/features of stone wool.

Origin & Properties of Stone Wool


Stone wool was discovered on the islands of Hawaii at the beginning of the century. It occurs there naturally as abyproduct of volcanic activity. In its manufactured state, stone wool combines the power of rock with the characteristics of typical insulation wool. In addition, thanks to its non-directional fiber orientation, it also exhibits some unique and valuable characteristics.

Thermal insulation

Stone wool is an excellent insulator and a vital component of an energy efficient building. In fact Insulation saves 12 times as much energy per pound in its first year in place as the energy used to produce it. [http://www.naima.org/pages/benefits/environ/effic.html]

Sound Absorption

The non-directional fiber orientation of the stone wool helps the absorption of acoustic waves and can reduce the intensity and propagation of noise.

Fire Resistant

Stone wool can withstand temperatures up to 2150º F (1177º C). Conequently it does not contribute either to the development and spread of fire or the release of toxic gases.

Water Repellent

Stone wool is water repellent yet vapor permeable. This means that the insulation cannot absorb water so the R-value is not affected. Additionally it is completely resistant to rot, mildew, mold and bacterial growth, contributing to a safer indoor environment.

Dimensional stability

Stone wool retains its characteristics unaltered over time. It undergoes only minimal changes in size or performance to the changing conditions of temperature and humidity.

How is Roxul Insulation made?

Production Process:

The production process for stone wool begins with the fusion of volcanic rock at a temperature of 1500° C (2732°F). Volcanic rock, slag and coke are automatically fed from the top of the cupola furnace. The melt runs out of the bottom of the furnace and onto the spinning machine, where the wool is spun. Minor amounts of binder and oil are added, and the wool is collected on a belt conveyor in the spinning chamber. The structure and density of the wool are adjusted before it enters the curing oven. These properties are maintained after the binder has been cured.

The cured wool then proceeds to the cutting saws and packing equipment or is led to off-line equipment for special treatment. The off-gases from the production – furnace, spinning chamber, curing oven – are cleaned in filters and after-burners before they enter the chimney. The waste inevitably created during the production is re-cycled.


A series of environmental equipment (filters, preheaters, afterburner and other systems of purification and collection) are featured in our production process to help make us environmentally responsible.

Existing Home Energy Efficient Tip #2 - Add Insulation

Existing Home Energy Efficient Tip #2 - Add Insulation

 
Insulation keeps your home warm in the winter and cool in the summer. There are several common types of insulation — fiberglass (in both batt and blown forms), cellulose, rigid foam board, and spray foam. Reflective insulation (or radiant barrier) is another insulating product which can help save energy in hot, sunny climates.
When correctly installed with air sealing, each type of insulation can deliver comfort and lower energy bills during the hottest and coldest times of the year.
Insulation performance is measured by R-value — its ability to resist heat flow. Higher R-values mean more insulating power. Different R-values are recommended for walls, attics, basements and crawlspaces, depending on your area of the country. Insulation works best when air is not moving through or around it. So it is very important to seal air leaks before installing insulation to ensure that you get the best performance from the insulation.
To get the biggest savings, the easiest place to add insulation is usually in the attic. A quick way to see if you need more insulation is to look across your uncovered attic floor. If your insulation is level with or below the attic floor joists, you probably need to add more insulation. The recommended insulation level for most attics is R-38 (or about 12–15 inches, depending on the insulation type). In the coldest climates, insulating up to R-49 is recommended.
Building new and thinking this information doesn't apply? Well good news, it does! Insulation is just as important when building new. The greatest thing about building new is you can start with the right foundation. We recommend using an ICF (Insulated Concrete Forms) foundation because the number one source of energy loss in your home is through the basement. Which is why starting with the correct foundation is one the most important decisions you can make when building a new home. To learn more about ICF foundation and walls read our first blog post.

Don't just stop at the foundation! You can use ICF's all the way to the trusses to provide even more insulation and energy efficiency. Don't want to spend the extra money on a full ICF home? Then use a higher R-Value of insulation of at least R-23. This combined with an ICF foundation will create an energy efficient home sealing the "envelope" or "shell" of your home — its outer walls, ceiling, windows, doors, and floors. This often the most cost effective way to improve energy efficiency and comfort. ENERGY STAR estimates that a knowledgeable homeowner or skilled contractor can save up to 20% on heating and cooling costs (or up to 10% on their total annual energy bill) by sealing and insulating.

ICF Facts

ICF Facts


What are Insulating Concrete Forms (ICFs)?
Insulated Concrete Forms (or ICFs) are forms or molds that have built-in insulation for accepting reinforced concrete. The first patent application for an ICF was registered in the late 1960’s. Since then, and particularly in the last 4 years, ICFs have been fast-becoming the mainstream preferred building product worldwide for all of the right reasons. These large, hollow blocks are stacked right off of the truck and filled with reinforcing bar and concrete. The end result leaves you with a high-performing wall that is structurally sound, insulated, strapped, has a vapor barrier and is ready to accept final exterior and interior finishes.

Why should you build with ICFs?

A better question would be, “Why would you consider building with anything else?” Here are a few of the best reasons to build with ICFs:


Comfort – Nothing blows through reinforced concrete. There will be absolutely no drafts or cold spots. ICF homeowners have commented on how constant temperatures stay within their homes. Because of the tremendous thermal mass of the exterior wall envelope, temperature peaks are smoothed, and therefore homes are noticeably warmer in the winter and cooler in the summer.


Safe & Healthy – There are no CFCs, HCFCs, or formaldehydes, and also no wood to rot and mold. ICFs are the answer for allergy and asthma sufferers. They have a two-hour fire rating and are termite and pest resistant. But most importantly, these structures can withstand a severe storm hit. Have you considered climate change into your future structure’s design?


Flexibility in Design – Reinforced concrete has tremendous proven design capabilities. For example, how many bridges do you travel over every day? ICF wall systems can support concrete floor and roof systems and give you the ultimate in innovative design.


Quiet – Your outside noises are eliminated. Is your future building site near train tracks, airports, highways or recreational vehicle trails? Maybe you simply do not wish to hear the neighbor mowing his lawn.


Energy Efficiency – Homes built with ICF exterior walls require an estimated 44% less energy to heat and 32% less energy to cool than comparable frame houses. Consequently, your HVAC systems can be downsized. Since floor systems are hung on the inside of the wall, real energy savings come when you design above-grade, thereby eliminating a huge heat loss area in conventional housing.


Build Green with ICFs - Protect our Children's Future!

Our world’s number one challenge is to reduce the amount of carbon dioxide that is being discharged into our atmosphere. The earth’s relatively sudden warming and consequent dramatic effects of climate change are directly related to these carbon dioxide emissions.

· Landfilling construction waste is reduced to less than 1% when you build with AMVIC. For every one tone of methane produced by landfilling practices, 20 tones of CO2 are produced.

· Every ICF home saves approximately 8.5 trees and effectively preserve nature’s air filters. Ask yourself the question, “How much oxygen does sand and gravel produce?”

· If we can reduce our energy bills by as high as 40%, we can reduce CO2 emissions by the same amount. The world’s international Kyoto agreement insists on a reduction of emissions by 50% just to slow down the effects of global warming. ICFs are a part of the answer to CO2 reductions.


Storm Warning!

Most importantly, ICF walls provide safe shelter from severe storms, whose occurrence is increasing in frequency as well as severity. Provinces and states with no past history of tornadoes are now experiencing them. As a result of the recent number of hurricanes in their areas, building codes are being upgraded along the seashores of the Caribbean, Florida and the Carolinas. Since 1983, insurance claims due to a majority of severe storm events have been doubling every five years. Protect your investment, protect your family, and protect yourself. Build with Insulated Concrete Forms.
