Exterior Surfaces06
Combining new and old technologies may be the best way to boost the durability of a home’s exterior-a key to long-term sustainability.
WHAT MAKES IT GREEN?
THE DURABLE HOUSE
Durability and the ability to handle rough weather are bottom-line standards for today’s roofing, siding, and windows. But more and more, sustainability is becoming part of the equation. A roof that fights smog and another made from recycled tires highlight green innovations that manufacturers have brought to the building envelope. Siding that incorporates power-plant ash, and concrete that filters water into the ground benefit the environment in unseen but very real ways. Some products, such as lime finishes, have weathered the test of time. Others, like concrete veneer siding that looks like stone, represent a new take on old traditions.


 


MADE TO LAST
A new take on old materials may be just what’s needed to extend the life-span of America’s housing.


PERVIOUS CONCRETE
As an alternative to costly underground drainage that puts a strain on local wastewater treatment, new concrete admixtures allow you to have a carport slab, or driveway that’s completely porous.


MASONRY VENEER
With the look of real stone, cement-based veneers weigh (and cost) much less than natural stone, yet have many of the same durability benefits. It’s easy to install them over rigid insulation, and they also can be color matched to siding, trim, or personal taste.


 


EUROSHIELD RUBBER ROOFING
The problem of old tires clogging landfills led to this green roofing system, which uses material from 600 to 1,000 recycled rubber tires to cover an average home. The shingles come in slate, shake, and tile styles. Designed for high performance in all climates, the roof is light weight, fire resistant, and maintenance free. There is virtually no waste; scrap shingles can be recycled. EuroSlate is shown. www.euroshieldroofing.com


BORAL MONIERLIFETILE: SMOG-EATING ROOF TILES
This concept is a breath of fresh air-a roof tile that acts like the catalytic converter on your car. The concrete roof tile is embedded with a photo catalyst that speeds up oxidation in the presence of sunlight, reducing nitrogen oxide emissions. Boral says 2,000 square feet of this first-of-its-kind product covering a roof mitigates the same amount of carbon dioxide as one car driven 10,800 miles. www.monierlifetile.com
