Parade of Homes

8 Parade of Homes Fall 2014 Energy-Efficient >> First-rate insulation and venting systems may not deliver the same wow factor as lush landscaping, stylish kitchens and integrated decor themes in new houses. but energy-efficient building materials are the secret to creating the real comforts of home. products that provide effective, efficient barriers to the elements will save money and energy, and they'll keep your home cozy in all weather conditions. Some features to keep in mind: eXTerior doors "Doors with a fiberglass skin will be warmer and look nicer," says trent reid, purchas- ing manager with mcmunn and yates building Supplies. "you really get what you pay for with doors." reid says fiberglass doors are damage resistant and can provide the look of wood, but with much better insulating properties. Steel doors require more care and main- tenance, but are also superior to wood for insulation. two of the biggest factors in maintaining the efficiency of exterior doors are weath- erstripping and door sweeps, so no matter what type of door you choose, these areas should receive periodic attention. iNsUlaTioN Insulation is typically considered in terms of its r-value, which measures its effective- ness. traditional batt or blanket insulation is still common, but not terribly efficient. Loose fill insulation isn't much better, but can be quick and easy to install, especially in attics. rigid board insulation has a high r-value, but is limited in its use. Spray foam, how- ever, works in many situations, boasts a high r-value and creates an air seal once it's expanded. though it comes with a higher initial expense, it's one of the best ways to build efficiency into a home. building codes specify minimum r-values for different zones of a house. For example, attics must be insulated to an r50 level. but some new home builders offer an option to increase those levels (for example, going up to r60 in the attic) to boost efficiency. reid says using insulated concrete blocks in the basement is another option that's gaining traction with homeowners looking for warmer downstairs walls. And rigid insulation on outside walls will increase r-values above ground. Finally, exterior walls can be covered in house wrap for a more complete air barrier.
