Building High-Performance Homes for the Upstate

Building smarter, stronger, and better for today and for your future. We believe homes should do more than look beautiful. Performance building means healthier indoor air, greater comfort year round, lower energy costs, and assemblies designed to hold up over time.

ComfortA better envelope helps your home feel more even, quieter, and more predictable through every season.
DurabilityMoisture control, airtight detailing, and disciplined assemblies protect the structure for the long term.
EfficiencySmarter energy performance supports lower operating costs and a better day to day living experience.

Why Build Smart?

At Grander Construction, we believe homes can do more than look beautiful. For homeowners who choose to prioritize it, high-performance building offers healthier indoor air, greater comfort year-round, and lower energy costs. By incorporating advanced methods and durable materials as upgrade options, we create spaces designed to last while helping reduce long-term environmental impact.

Performance is not one product or one upgrade. It is the result of good design, disciplined sequencing, and assemblies that work together as a complete system.

What Smart Building Delivers

  • Better indoor air quality and comfort.
  • Lower energy use over time.
  • Better moisture and pest control.
  • Greater long term durability.
Build Science Practice 01

ZIP System Envelope

A continuous air barrier with ZIP System sheathing provides superior resistance to air leakage, improving energy efficiency and lowering operating costs. By controlling both air and moisture movement, it enhances indoor air quality while protecting the structure from long term damage. This system also minimizes insect and pest intrusion, creating a tighter and healthier living environment. The result is a durable, low maintenance building envelope engineered for lasting performance, with detailing at soffit, fascia, and foundation transitions ensuring a fully continuous seal.

Windsor Windows

Energy efficient Windsor aluminum clad windows are selected for lasting performance, low maintenance, and the architectural finish expected in a Grander home. These assemblies help minimize thermal bridging and air infiltration while supporting better comfort and a more refined exterior envelope.

Airtight Wall Assemblies

Airtight wall assemblies with no unnecessary roof penetrations support superior moisture and air control. Every penetration is sealed deliberately to protect the continuous building envelope and reduce the kinds of small failures that lead to long term comfort and durability issues.

Continuous Air Barrier

A continuous air barrier across critical junctions helps the full enclosure work as one system. By reducing uncontrolled air leakage, the home performs more predictably through seasonal swings, supports indoor air quality, and protects structural assemblies from hidden moisture movement.

High-Performance Insulation

High-performance construction creates a continuous building envelope that minimizes uncontrolled air movement and thermal loss. By combining a spray applied air and thermal barrier at the roof deck with dense-pack cellulose in the wall cavities, we deliver both airtightness and hygroscopic moisture buffering. This proven assembly reduces thermal bridging, stabilizes interior temperatures, and significantly lowers heating and cooling loads.
