Platinum Structural Insulated Panels are made with graphite-infused polystyrene (GPS) insulation cores and provide up to 21% more R-Value per inch than our standard white EPS insulation.
Platinum Structural Insulated Panels are most effective when space is limited. The graphite-infused polystyrene (GPS) cores increase the R-Value per inch, thus requiring the need for large, multi-layered walls. West-Eco’s 6” GPS SIP provides an effective R-28 without the need for studs every 4’.
Our largest Structural Insulated Panel can be made up to 8’x24’ and from 4” to 12” in thickness. This means that in one full-sized sheet contains only EPS foam and an OSB sheet on either side, no studs required.
A primary benefit of SIPs in roofs is their long clear span capability. The large, single-piece panels can span up to 20 feet, reducing the need for interior columns or other support.
SIPs can meet easily meet the requirements of a green roof by providing fewer gaps in the roof system and can handle larger loads to accommodate the soil, plants, and water.
Builders can save money through decreased construction and labor costs. A high performance building envelope often allows HVAC equipment to be downsized and ductwork to be minimized.
Material costs of SIPs may cost no more than conventional stick framing…IF…the stick framed envelope is built to compare to the same efficiencies as SIPs provide.
Overall project costs of SIPs over 2×6 stick framed construction is up to 30% less!
SIP homes are 15 TIMES more airtight, and more energy efficient that a stick-framed home.
Stick-framed buildings rely on lumber at regular intervals to provide structural support. 15-25% of the shell of a stick-framed home is lumber, compared to as little as 3% in the shell of a typical SIP home.
Once the SIPs are installed, you can apply virtually any finish to polish off the exterior – stucco, stone, Hardie Board, brick or clapboard.
Efficient SIP building envelopes are a regular part of Net-Zero Energy Projects as well as those seeking Green Credentialing.
SIPs can be used in the roof system of a custom designed home where either a flat or low slope roof is present or where vaulted ceilings are desired.
When you pair the timeless beauty of Timber Framing with SIP Construction, you get a Green and Sustainable Building by using products that are renewable, provide long-term Energy Efficiency and will maintain Structural Integrity far longer than a typical stick frame building.
Any design or structure can be built using SIPs. West-Eco converts and creates in-house shop drawings from previously designed Architectural and Structural drawings.
Electrical chases come standard in all SIP packages. In the walls, the standard chases are at 16” and 45” horizontally from the floor and vertically, every 4’ running floor to ceiling.
Depending on the size and design of a home, it can be enclosed with SIPs within days or even hours. This saves money on labor, insurance, and financing, as well as energy on the job site.
SIPs cut heating and cooling costs by as much as 60% over products used for conventional “stick” construction.
Components that comprise SIPs come from renewable resources. The insulation is a form of recyclable plastic, and oriented strand board (OSB) is made from fast growing trees and shrubs once considered waste by the lumber industry.
