Hemp Insulation – INNOVATIVE

Hempitecture HempWool is made from 92% industrial hemp fiber. Because it’s mostly plant based, it’s non-abrasive and non-toxic It comes in 16 and 24-inch batts with R-values of 7, 13, 20 and 28. Working with hemp wool requires the eye protection and dust masks typical of any insulation job. It’s best to cut the material with a table saw and an angle grinder.      Discuss this Product

Structural Insulated Panels (SIPs)

Structural insulated panels (SIPs) are a high performance building system for residential and light commercial construction. The panels consist of an insulating foam core sandwiched between two structural facings, typically oriented strand board (OSB).  SIPs are manufactured under factory controlled conditions and can be fabricated to fit nearly any building design. The result is a building system that is extremely strong, energy efficient and cost effective. Building with SIPs will save you time, money and labor.

Are Structural Insulated Panels More Expensive?

Building with SIPs generally costs about the same as or less than building with wood frame construction when you factor in the labor cost savings resulting from shorter construction time and less jobsite waste.  Other savings are realized because smaller heating and cooling systems are required with SIP construction.

SIPS are Ideal for Zero Energy Construction

SIPs provide insulated, air-tight construction, with lower costs for getting to zero net energy than traditional stick frame construction. All SIPs manufacturers have had net zero projects and most SIPs projects are HERS rated in the 35 - 45 range pre renewables. The Rocky Mountain Institute’s Innovation Center used SIPs for their new zero energy commercial building, and SIPs are ideal for zero energy homes as well, such as this single family home in Houston.

Highly compression resistant wood fiberboard insulation for floors, walls, ceilings and roofs. Can be used in facades and fully sheathed roofs in rainscreen application when protected by ProClima WRB or roof underlayment.


  • Biologically safe (natureplus® certified- biologically save, carbon sequestering insulation that is vapor open
  • High thermal mass, allows product to protect interior from solar heat in summer. Highly sound absorbing
  • Raw material for all GUTEX insulation boards comes solely from wood that is harvested and grown using sustained forestry management practices
  • Boards are made using the dry process meaning that the boards contain 96% wood, and maximizes the use of this sustainable, recyclable natural resource
  • When used as insulation in exterior walls or roofs, THERMOSAFE WD needs protection by WRB (Pro Clima MENTO Membranes) or cover board by GUTEX cover boards (MULTIPLEX TOP, ULTRATHERM, THERMOWALL or MULTITHERM)


  • R-value/in: R- 3.6 per inch (U-value 0.039 W/mK)
  • THERMOSAFE-WD 40 Board R-value: 5.8
  • Custom orders in bulk possible for other thicknesses
  • Perm rating: 44/inch (Sd 0.24m for 40 mm board)
