Perlite insulating concrete is a combination of perlite aggregate, Portland cement, air entraining agent, water and/ or other additives producing a concrete with an oven dry density of 800 kg/m3 or less. 1.3 – Usage Field placed perlite insulating concrete is commonly used for insulating roof decks, fills and other semi-structural insulation
In general, expanded perlite is a little bit better as far as insulation goes. When you use exfoliated vermiculite in a dry state it would be fine as well. In case you want the insulation to be rigid through mixing with clay slip, use perlite, this won't take up as much water as vermiculite.
Production, properties, and applications of perlite insulating concrete are described including miming and manufacture of perlite aggregate, variation in different perlite deposits, basic cost data, physical properties of perlite concrete, and significance of aggregate hardness.
Perlite concrete roof decks with polystyrene insulating bo ard meet the criteria for U.L. Class 90 and FM I -90 wind resistance. ROOF INSULATION Perlite concrete roof deck insulation is an ideal base for built -up and single ply roofing systems. It has superior wind and fire resistance over other roof insu lation material and with the additional of
Perlite is substituted for sand or heavier aggregates in concrete and plaster mixes to reduce weights and achieve better insulation and fire protection. Perlite is naturally incombustible, resistant to thermal transmission and lightweight.
The versatile mineral. Perlite plays an important role in a wide variety of construction-related uses including: as an aggregate in lightweight insulating concrete and plaster; as a loose fill insulation material for concrete masonry blocks, cavity walls, in residential homes; and in a variety of specialty applications including fireproofing sprays, chimney fills, interstitial floors ...
Perlite insulating concrete consists of an appropriate mixture of portland cement, perlite aggregate and water. Its weight can be varied in the range of 20 to 50 pounds per cubic foot, depending on the mix design selected. This is in comparison to sand and gravel concrete which weighs 140 to 150 ...
FB pizza oven insulation doesn’t provide a rigidity to the structure, so if you are looking for a mobile application, you will probably want to use both FB insulation AND a vermiculite / perlite mix. We often suggest “skinning” the dome with a 1″ (2.5 cm) layer of vermiculite / perlite, and then insulating with a FB insulation blanket.
Perlite concrete roof deck insulation is an ideal base for built-up and single ply roofing systems. It has superior wind and fire resistance over other roof insulation materials and with the addition of polystyrene insulation board sandwiched in the perlite concrete, high thermal resistance values, are …
Perlite concrete also has sound deadening properties, and is thermal insulating as well, depending on mix design. Generally speaking, the lighter the weight, the greater the isolative properties. Please use these mix designs as a guide recognizing that each and …
Perlite is a versatile and sustainable mineral that is mined and processed with a negligible impact on the environment. And the green community recognizes perlite-enhanced products—like lightweight insulating concrete roof decks—as a high-performance solution drawn from a natural material of nearly unlimited supply throughout the world.
Oct 04, 2013· The frost wall of our addition is concrete block. What is the best loose fill insulation for the hollow cores? Vermiculite? Perlite? EPS beads? (I understand they are made with the waste of EPS board, so this mitigates the environmental impact? Other ideas? Thanks.
Perlite concrete aggregate combined with portland cement and water produces a lightweight insulating concrete used for lightweight roof decks, floor fills, lightweight structural decks, insulation for steam and coolant lines, bases of cryogenic storage tanks, oven insulation, interstitial spaces in reconditioned water and sewer lines, interstitial floors in hospitals, lightweight pre-cast ...
Expanded perlite’s high insulating qualities, light weight, and versatility make it an essential part of the construction industry for loose fill insulation and lightweight insulating concrete. It is the ideal construction aggregate filler for masonry fill insulation, roof decks, floor systems and other significant areas that need insulation.
Construction. Perlite has many applications in the construction industry from slab insulation to insulated concrete for in ground vinyl pools. When mixed with concrete it's fire resistant, lightweight, & insulating.
Perlite insulating concrete pool base can substantially reduce heat loss to the ground thus keeping pool water warmer for a longer swimming season. This will reduce energy costs when pool water is heated. In addition, perlite pool base provides a firm, smooth, foundation that prolongs the life of vinyl liners. ...
Physical properties of perlite concrete vary according to mix designs. Perlite concrete can be made with a dry density of 320 kg/m3 or with the addition of sand or other aggregates up to 1440 kg/m3. The lower the density, the higher the insulating value. For most uses to maintain a proper balance between insulation value and compressive ...
insulating cellular concrete as the material of choice for roof decks. H. ere is a secret that has been around for many years—the. B. ACKGROUND. Insulating concrete roof decks come in two basic types—produced with either cellular concrete (preformed foam) or with expanded aggregate concrete (perlite or vermiculite).
Insulation R values of various materials: This article provides a Table of Insulation Values and Properties for Various Insulation Materials useful in procedures to measure or calculate heat loss in a building, defines thermal terms like BTU and calorie, provides measures of heat transmission in materials, building insulation design data, and heat loss in a building.
Formulas for Lightweight Concrete. ... (such as concrete) serve as an insulation material, the compromise is rarely worth the trouble. If the hemp provided a significant portion of the volume, it might approach a good insulation material, similar to papercrete. ... Perlite concrete can weigh between 20 and 09 lbs. per cubic foot, depending on ...
Typically ground floors are constructed with dense concrete covered with dense screed; second storey floors over garages and car parks are also usually built with dense concrete and screed giving little thermal insulation. A screed containing perlite can reduce thermal conductivity from 1.04 to between 0.15 and 0.25 w/m o C.
Perlite insulating concrete is a m i x t u r e of expanded perlite, port-land cement, water and an air- e n - t r aining agent. The dry concre t e weighs from 20 to 50 pounds per cu-bic foot, depending on the mix se-lected. Perlite concrete can be placed monolithically on flat, un-e v en, curved, or sloping surf a c e s .
Oct 31, 2015· This video shows you the basics of making Insulated Concrete out of Portland Cement and Vermiculite (or Perlite). The resulting mix is only 15% of the normal concrete weight but is heat/fireproof.
Increase or decrease the amount of perlite as needed to achieve the desired insulation value and compressive strength. Perlite concrete mixed at a ratio of 1 part cement to 6 parts perlite has an insulation value, or "k" value, of 0.64 and a compressive strength of 125 to 200 pounds per square inch.
