Different fibres are available depending on your lifestyle & the room you’re carpeting. For example, nylon treated with stain protection is great for heavy traffic areas, and homes with pets and children. Wool carpets, on the other hand, are less stain resistant, but minimize allergic reactions & improve air quality.
Are there carpet options that protect the environment?
Yes! Before exploring ‘green’ carpeting, there is the out-right benefit of all carpets that they are natural insulators, providing us with extra warmth in the colder months and lowering energy usage. There is also a wide range of carpeting available that is made with recycled or sustainable materials such as recycled nylon, recycled polyester, or wool.
- The use of carpet in a wall-to-wall application actually increases the R-value, or insulation level, of the carpet area, potentially saving homeowners like you utility costs while reducing energy use. The R-value (thermal resistance) measures how much a material resists the movement of heat through a ceiling, wall, or floor in a building. The higher the number, the more effective the insulation.
- Recently, tests carried out at the Johns Manville Technical Center Thermal Labs, one of the most sophisticated laboratories of its kind in the world, confirm carpet and pad significantly increase R-value compared to other flooring materials. Results varied according to the carpet’s construction, with heavier products generally providing higher R-value. Carpets were tested with and without cushion, and the combination maximized the R-value. Carpet really is warmer.
- Test results from the different carpet constructions were compared to three hard surface products – ceramic tile, laminate, and engineered hardwood – and the differences were dramatic.
Is it true that carpets may aggravate my allergies/asthma?
As with any surface, if the carpet is left unattended for an extended period it will eventually become dirty, causing allergic reactions to the contaminants in your home. When cared for properly, carpets actually trap dust particles instead of allowing them to continue to circulate in the air we breathe. Once the carpet has been vacuumed, the dust particles are permanently trapped and can no longer inflame symptoms of asthma or allergies.
“In 2002, two schools in North Carolina were the subject of a study conducted by Research Triangle Institue (RTI) and University of North Carolina (UNC) investigators. One school had mostly resilient tile floors, while the other was 70-75% carpeted. The study found that airborne contaminants, possible sources of allergens, were higher over the tiled floors than over carpet.
Also in 2002, Professional Testing Laboratory studied the effect of foot traffic on air quality, using commercial carpet and commercial vinyl flooring. Following 16 minutes of foot traffic over both surfaces, the particulate concentration over the vinyl floor was found to be four times that of carpet.
Other studies, including one using Computational Fluid Dynamics (CFD), have reinforced these findings and concluded that carpets actually reduce exposure to particulates and potential adverse health effects.
In a recent paper, “Carpet, Asthma and Allergies – Myth or Realty,” Dr. Mitchell Sauerhoff, Ph.D., DABT, examined numerous scientific studies and other research contradicting some long-held beliefs on carpet’s alleged negative characteristics.
Sauerhoff concluded, “…based on the available science, carpet does not cause asthma or allergies and does not increase the incidence or severity of asthma or allergies symptoms. In fact, with respect to asthma and allergies, multiple studies have reported fewer allergy and asthma symptoms associated with carpet.”
Is carpet difficult to care for?
This depends on the type of carpet. Some carpets are designed for luxury and aesthetic, and are not intended to withstand high traffic or rough usage. Other types of carpet are very durable and stain-resistant, ideal for high-traffic areas, families with young children and busy lifestyles. The more ‘luxurious’ carpets will require more maintenance, and the carpets that are designed for durability and resistance will not require as much care.
