GREEN OP­TIONS IN HOME SID­ING

Richmond Times-Dispatch Weekend - - SCOREBOARD -

If new sid­ing is on the list of must-do home projects this year, there are many fac­tors to con­sider. Though it's a trans­for­ma­tive ren­o­va­tion, re­place­ment sid­ing is a sig­nif­i­cant and po­ten­tially ex­pen­sive un­der­tak­ing. There­fore, care­ful con­sid­er­a­tion must be given to the ma­te­ri­als used and their main­te­nance, longevity, in­su­la­tion fac­tor, and cost. Many home­own­ers also want sid­ing that is eco-friendly.

Sus­tain­abil­ity is an im­por­tant con­sid­er­a­tion for many home­own­ers. Data from the Na­tional As­so­ci­a­tion of Home Builders' "Green

Mul­ti­fam­ily and Sin­gle Fam­ily Homes 2017 SmartMar­ket Brief " in­di­cates that at least onethird of sin­gle-fam­ily and mul­ti­fam­ily home builders who were sur­veyed said that green build­ing is a sig­nif­i­cant por­tion of their over­all ac­tiv­ity (more than 60 per­cent of their port­fo­lio). By 2022, this num­ber should in­crease to nearly one-half in both the sin­gle-fam­ily and mul­ti­fam­ily sec­tors. Green build­ing has be­come an im­por­tant and es­tab­lished part of the res­i­den­tal con­struc­tion sec­tor.

Where sid­ing is sourced, the ma­te­ri­als that go into its fab­ri­ca­tion and how well that sid­ing in­su­lates a home are key as­pects of its green fac­tor. The fol­low­ing are some of the more sus­tain­able op­tions in home sid­ing.

Re­claimed tim­ber. A house sided with clap­board, or a log cabin-in­spired look, is iconic. These types of sid­ing are typ­i­cally made from in­sect-re­pel­lant pine, cedar, cy­press, or red­wood. While lum­ber cer­ti­fied by the For­est Stew­ard­ship Coun­cil is en­vi­ron­men­tally friendly, home­own­ers may want to seek out re­claimed lum­ber. This wood has his­tory and causes very lit­tle en­vi­ron­men­tal im­pact. Plus, tim­ber sal­vaged from old build­ings or fallen trees may be su­pe­rior to new wood be­cause it likely came from slow­grow­ing, old trees with dense grain.

Brick. Avoid any neg­a­tive en­vi­ron­men­tal im­pact by choos­ing lo­cally pro­duced or re­claimed bricks — or those made from post-con­sumer con­tent. The longevity of bricks can of­ten off­set the en­ergy ex­pen­di­ture in their man­u­fac­ture. Plus, many bricks are made from nat­u­ral clay, which can be an ex­cel­lent in­su­la­tor.

Stucco. HouseLogic said tra­di­tional stucco is made from sand and Port­land ce­ment mixed with wa­ter to make a us­able plas­ter. It's tough and durable — of­ten last­ing the life of the house. Eco-friendly vari­ants in­clude stucco made with an earth-and-lime mix­ture, off­set­ting the CO2 emis­sions as­so­ci­ated with ce­ment pro­duc­tion. Stucco can re­duce air in­fil­tra­tion that causes drafts in a home.

Fiber-ce­ment. Fiber-ce­ment is sim­i­lar to stucco in that it is made from sand, Port­land ce­ment, clay, and wood pulp fibers. It can be fire-re­sis­tant and in­sect-proof and will not rot. It's a sta­ble ma­te­rial that can re­cover al­most 80 per­cent of the ini­tial cost, ac­cord­ing to the Na­tional As­so­ci­a­tion of Real­tors.

Stone. This non­re­new­able re­source can be beau­ti­ful on a home and durable, but min­ing it can im­pact the en­vi­ron­ment. If home­own­ers can use re­claimed or dis­placed stone, those are more sus­tain­able op­tions. Man­u­fac­tured stone, which is ce­ment and other ma­te­ri­als molded to look like stone, is also aes­thet­i­cally ap­peal­ing and more eco-friendly. Re­plac­ing sid­ing is a sig­nif­i­cant un­der­tak­ing. Home­own­ers can con­sider sus­tain­abil­ity when se­lect­ing re­place­ment sid­ing ma­te­ri­als.
