Concrete Wall With Insulation In The Middle

In this application thermaeze was placed on the outside of the wall in order to assist the steel decking and support design.

Concrete wall with insulation in the middle. With over 35 years of experience we are the undisputed leader in concrete sandwich wall technology and can help you create building envelopes that maximize energy efficiency durability and performance. The insulation becomes an integral part of the wall panel when the concrete is placed. Thermomass is an insulation product that contractors embed between two layers of concrete. The r value of thermaeze is 9 4 for 2 inches of the material and a 10 wall.

With either method a 2 inch thick layer of expanded polystyrene eps or extruded polystyrene xps is standard in warm climates. Most homeowners require insulation with an r value between 13 and 21 in their basements where most concrete walls can be found. Rigid board exterior insulation systems need little or no maintenance and varied exterior surface finishes are available to blend with any kind of architecture.

Interior insulation refers to insulation applied to the interior side of the concrete masonry as shown in figure 1. Adding layers of closed cell foam polyurethane sheeting or reflective barriers to a concrete wall can all increase the insulation value of concrete. The insulation may be rigid board extruded or expanded polystyrene or polyisocyanurate closed cell spray polyurethane foam cellular glass fibrous batt or fibrous blown in insulation note however that fibrous insulation is susceptible to moisture.

We are planning on using steel forms and pouring the inner 6 with the foam lacing the exterior of the form and then after the concrete sets moving the form along the extended ties to pour the outer 4 with the 2 foam on the middle wall and pour in 100 foot sections. 2 calculate how many inches of insulation you need to achieve your. Insulating concrete form or insulated concrete form icf is a system of formwork for reinforced concrete usually made with a rigid thermal insulation that stays in place as a permanent interior and exterior substrate for walls floors and roofs. Moving along the wall the crews placed insulation the rebar and then the exterior concrete wall panels.

Warnings if installed improperly and not sealed completely moisture will gather behind insulation components to a concrete wall allowing for mold and mildew growth a potential health hazard. A thermomass wall has concrete on the inside and the outside with the insulation in the middle.
