Liteblok™ 38

Liteblok 38 Liteblok 38

Applications include

  • Commercial construction
  • Demising walls
  • Fire walls
  • Residential home construction (external and internal walls)
  • Safe rooms
  • Sound absorbing walls
The lightweight quality of the block and the discrete nature of the air pockets within are evident by the fact that our Liteblok 38 will float on water. Framing, fiberglass insulation, sheathing, vapor barriers and sheet rock can all be eliminated by using Liteblok 38 thereby saving time and money. Savings in heating and cooling expenses can also be achieved (see article in Links & Resources). Liteblok 38 exceeds the energy efficiency requirements that many municipalities require. For example, in Austin, Texas, Liteblok Grande 38 offers an R-35 rating (see International Energy Conservation Code or IECC Code and REScheck for equivalent R values for high thermal mass systems) as an eight inch thick form with no additional insulation.

"All week, the temperature outside was around freezing, inside my Liteblok™ home it stayed between 63°F and 67°F without any heat"

The method of determining equivalent R value comes from the IECC. The IECC are our Energy Codes, they are essentially what permit offices within the United States use in determining a structure’s compliance to energy efficiency requirements. The IECC recognizes than high thermal mass systems such as Liteblok contribute to energy efficiency not only by virtue of their thermal insulating performance but also by their ability to store energy. The IECC developed equivalency tables to equate the energy performance of high thermal mass systems with wood frame systems, hence the term equivalent R value. Equivalent R value varies by climate as per the IECC and is determined by comparing steady state R values with climate zone maps. The equivalent R value system serves the practical purpose of allowing one to size air conditioning equipment appropriately. Liteblok™ structures are very energy efficient; Liteblok reduces heating and cooling loads and the size of A/C systems.
Wood frame and other traditional methods of construction tend to be very labor intensive with labor costs often being many times the cost of the materials themselves. Liteblok™ is designed to simplify and quicken construction. Labor costs to erect a wall are typically less than 10% of the material cost.
Long lasting, durable and affordable structures can be built with Liteblok™. Its light weight means significantly less cement is consumed and reduced freight loads result in less energy consumption and pollution during transport. It does not rot, is not attacked by vermin, and does not absorb moisture into its core resulting in a lower maintenance requirement. Minimal job site waste is generated during construction. Lightweight cellular concrete absorbs sound (while dense concrete reflects sound) and significantly reduces indoor noise resulting in quieter rooms and little to no sound transmission to adjoining rooms.

"While building my Liteblok™ home, when the outside temperature exceeded 100°F, inside was still around 70°F without doors, windows or A/C installed"

Liteblok 38 is a very healthy and environmentally friendly green building material. No ozone depleting or hazardous chemicals are used during manufacture. Heavy use of pesticide is not required prior to construction. Liteblok 38 is a breathable material that removes toxins from the air and naturally maintains a low relative humidity within the home. Mold growth is inhibited by the lack of moisture and organic material (such as wood or paper) combined with the alkaline environment of our cement based system. Because Liteblok™ is a clean breathable material it is ideal for those suffering from asthma, allergies and chemical sensitivities.
Home owners can enjoy savings as great as 35% on their home insurance using non-combustible Liteblok™ for their walls versus wood frame. Lower electricity and heating bills and lower maintenance costs also provide annual savings to property owners. Learn about Liteblok applications and benefits by visiting our Solutions page.

Bond Beam and Lintel Blocks

A bond beam is a continuous beam, usually constructed of concrete and reinforced horizontally with rebar, on top of supporting walls. The purpose of the bond beam is to tie walls together and distribute weight evenly to the walls below. Our bond beam blocks are interlocking and mortarless and allow for vertical and horizontal steel reinforcement (see photo). The vertical rebar from blocks below (and above) can be tied to the horizontal rebar running through the blocks creating a strong structure with evenly distributed loads.

A lintel is a support beam above windows and doors. Lintel blocks are used in cases where flat bottom Liteblok blocks will not suffice. Our lintel blocks are similar in appearance to the bond beam block but have flat bottom surfaces

Our bond beam and lintel blocks are made of the same material and have the same physical properties as Liteblok 69.

                diameter vertical holes. 8 lb nominal weight                   
            Liteblok™ Grande: 7.87" (200 mm) deep x 7.87" (200 mm) tall x 15.75" (400 mm)
                wide with one 4" diameter horizontal hole and two 3.15" (80 mm) diameter

            Flat top for bond beams (tops of walls)
            Flat bottom for lintels

To take advantage of the modular design and to avoid cutting the blocks, walls and openings are typically dimensioned in multiples of whole or half blocks.
A pair of Liteblok 38 Standard blocks can be ordered for evaluation and mailed anywhere in the US for a charge of $30 (Order from our Ebay Store).
