Structural Insulated Panels or SIP’s

 The outside walls are made with SIP’s.  Made by R-Control the SIPs (Structural Insulated Panels) are a strong structural system consisting of Perform Guard Expanded Polystyrene (EPS) insulation laminated to oriented strand board (OSB) forming a structural panel. These panels are formaldehyde free and termite resistant.   

In a test program performed at the Oak Ridge National Laboratories, SIP’s exceeded standard frame walls in energy efficiency by over 50%.

 

Another test program was sponsored by the Structural Insulated Panel Association (SIPA). Testing demonstrated that panel joints did not create cold spots. This contrasted to stick built walls which had cold spots over each lumber stud in the testing. Dramatically reducing cold spots provides a more comfortable interior environment.

Insulated Concrete Forms, ICF’s

To make the basement more comfortable insulated forms made of Perform Guard polystyrene are used to form the basement walls and are left in place as part of the wall.    A basement wall built with this system has 17 times the insulating value of a standard concrete wall.

  Silent floor system

The Silent floor system is designed with engineered lumber.  It includes the floor trusses and the flooring glued and nailed together.  With proper installation it eliminated squeaks, is stiffer than a regular floor system, and uses 1/3 less natural forest than a standard floor system.

 Exteriors

 Envision homes exteriors are finished with materials which have a long life expectancy and minimum maintenance.  This allows for increased peace of mind and a decrease in time and expense maintaining the house.
