Building Envelope

A building envelope is the physical separator between the conditioned and unconditioned environment of a building including the resistance to air, water, heat, light, and noise transfer. The building envelope is all of the elements of the outer shell that maintain a dry, heated, or cooled indoor environment and facilitate its climate control. Building envelope design is a specialized area of architectural and engineering practice that draws from all areas of building science and indoor climate control. The control function is at the core of good performance, and in practice focuses, in order of importance, on rain control, air control, heat control, and vapor control.

The many functions of the building envelope can be separated into three categories:

  • Support (to resist and transfer structural loads)
  • Control (the flow of matter and energy of all types)
  • Finish (to meet human desires on the inside and outside)

Upgrade Your Building’s Efficiency

Components of the envelope are typically:

  • Walls (Advanced Framing & Spray Foam Insulation)
  • Floors
  • Roofs (Standing seam metal roofs)
  • Doors
  • Fenestrations (any opening: windows, skylights, clerestories, etc)

Spray Foam Insulation

At NATiVE we use spray foam on most of our homes as the best method of achieving a high performance thermal building envelope. Residential spray foam is the most cost effective insulating material that seals your home from air and moisture intrusion, saves on utility bills, and protects your family’s health from airborne pollutants, and allergens.

NATiVE customers have a lot to like about the energy efficient windows we use at a very economical price. The windows we use meet ENERGY STAR® qualifications in all climate zones. The materials they’re made from block thermal transfer nearly 700 times better than aluminum, and full-perimeter weatherstripping helps provide superior insulation. The field-proven composite material that make up the energy-efficient windows allows us to offer high-quality and low-maintenance products at a lower cost.

With their durable, environmentally friendly material construction, the windows NATiVE uses offer the strength of solid wood and twice the stability and rigidity of vinyl. The composition, which has more than 30 U.S. patents, ensures your windows will last for decades.

At a time when more people care about the environmental impact of their choices, NATiVE homeowners can feel good about the products NATiVE uses to build their homes. The frame and sash of the windows we use contain 40% pre-consumer reclaimed wood fiber by weight, and the glass contains 12% reclaimed glass by weight.

The windows we use meet ENERGY STAR® qualifications in all climate zones. The materials they’re made from block thermal transfer nearly 700 times better than aluminum, and full-perimeter weatherstripping helps provide superior insulation. NATiVE windows meet or exceed Performance Grade 30 air, water and structural requirements, helping to keep the wind and weather outside. Traditional and commonly used vinyl windows in dark colors can become soft when exposed to the sun’s intense heat. NATiVE windows retain their rigidity and strength in temperatures exceeding 160 F.
