Custom Components of Eagle River, Inc., was formed by Glenn Schiffmann, as Founder, President and CEO, in 1990. The original business plan was to provide open wall framing packages (shells) to other residential and light commercial builders in the Eagle River area. Currently employing designers, drivers, accountants, clerical, administrative, manufacturing, sales, field crew, and maintenance personnel, the firm services builders and general contractors throughout northern Wisconsin and the Upper Peninsula of Michigan. In the fall of 2001, Schiffmann established a new corporate identity to take charge of Custom Components’ emerging general residential and commercial contracting business. This new company, CornerStone Custom Builders, Inc., has built up to 100 homes per year. Today, CornerStone is the principal contractor for 120 area subcontractors.

The Need for a Solution

Is it time to introduce a better way to build? Is it time to incorporate engineered, high performance, composite materials into our living space – materials that offer clean and comfortable living space – materials with tremendous R-values – materials that offer energy savings that will help reduce our dependence on fossil fuels?

Solution is Found in High Performance Composites

Composites offer incredible performance, having gained the trust of engineers in aviation many years ago. The material can withstand extreme pressure and temperature changes with favorable expansion and contraction rates.

Composites are trusted by the marine industry, where impact resistance and watertight qualities are paramount.

Corvette cars have used composites from the very beginning for their light weight and strength characteristics. High performance composites are all around us and they have been for years.

The military uses composites for their ballistic panels as the replacement for steel. The lightweight characteristics make the ships faster, using less energy to travel. Structurally sound and dependable, composites are trusted materials for infrastructure where corrosion has been a concern in applications such as bridges.
