Insulation Solutions

Overview

These are common insulation solutions, organized by cost, complexity, and performance. Example assemblies and material choices shown here should help you get started on the right insulation combination for your climate and your specific project requirements.

Preinstalled Insulation

In contrast to insulating wall panels, such as SIPS or ICF, the am‑cor System is first & foremost a structural system: by design, preinstalled insulation is not included in am‑cor Kits.
This allows you the flexibility to:
  • Choose which insulation assembly is right for your project, budget, and lifestyle
  • Swap in healthy alternatives to ensure low-VOC, high indoor air quality, and fire safety
  • Achieve higher performance and a tighter building envelope with site-installed insulation (no joints = no air leakage)
  • Avoid environmental degradation caused by toxic polystyrene pellets/waste material blowing around your building site, onto neighboring properties, into waterways and generally disrupting the environment

What R-Value / U-Value does the am-cor System have?

Example Wall Insulation Assemblies

You can mix and match different aspects of these wall insulation assemblies, to get the thermal resistance needed for your project.

am‑cor Basic Wall Insulation

am‑cor Basic Wall Insulation

Wall - Basic

This is the least expensive assembly which meets the minimum IBC & IRC code requirements.  The outer surface of am‑cor walls is made of seamless amcorite Ferrocement. Because there are no junctions or gaps, insulation in am‑cor walls functions better than standard applications because the seamless Ferrocement skin eliminates air infiltration.




am‑cor Better Wall Insulation

am‑cor Better Wall Insulation

Wall - Better

This assembly exceeds building code requirements, and offers good performance at a relatively low cost. Its average R value is similar to the average functional R value of many SIPS, ICF, and other manufactured insulating wall panels. However, since the amcorite structural Ferrocement skin is seamless, there is zero air infiltration through the am‑cor wall.  Air infiltration in normal walls reduces manufacturers' stated R values by up to 50%.





am‑cor Super Wall Insulation

am‑cor Super Wall Insulation

Wall - Super

This super-insulated wall sample includes an inner framework for hanging finishes, separated from the am‑cor structural framework by Aerogel thermal breaks. The specified type of spray foam functions both as a vapor barrier and an excellent insulator. Its average total R value substantially exceeds both codes and most manufactured wall panel products. This assembly eliminates thermal bridging from the building's structure to the conditioned interior.





am‑cor Passiv Wall Insulation

am‑cor Passiv Wall Insulation

Wall - Passiv

Superinsulation is a major part of the Passivhaus philosophy. Buildings built to the Passivhas specification have a lower carbon footprint, and require very little energy to heat or cool – consuming minimal fossil fuels or electrical power to create a comfortable environment all year round. Passivhaus designs often feature a complete unbroken thermal break between the inner and outer structures. Many European examples are framed with wood. This Passivhaus am‑cor wall utilizes a double wall separated by aerogel thermal breaks, and is framed in galvanized steel with a galvanized Carbon steel Ferrocement coat. This assembly eliminates thermal bridging from the building's structure to the conditioned interior.


Example Roof Insulation Assemblies

You can mix and match different aspects of these roof insulation assemblies, to get the thermal resistance needed for your project.

Roof - Basic

Similar to the Basic Wall Insulation Assembly above, this Basic Roof Insulation Assembly with attic is an inexpensive assembly and actually exceeds the minimum IBC & IRC code requirements.

Roof - Super

This superinsulated roof assembly can be used in conjunction with the Super Wall assembly by continuing the wall's inner finish framework along the roof frame interior. This assembly eliminates thermal bridging from the building's structure to the conditioned interior.

Roof - Passiv

Superinsulation is a major part of the Passivhaus philosophy. Buildings built to the Passivhas specification have a lower carbon footprint, and require very little energy to heat or cool – consuming minimal fossil fuels or electrical power to create a comfortable environment all year round. Passivhaus designs often feature a complete unbroken thermal break between the inner and outer structures. Many European examples are framed with wood. This Passivhaus am‑cor roof utilizes an insulated ceiling space with an insulated drop ceiling cross frame separated by aerogel thermal breaks, and is framed in galvanized steel. This assembly eliminates thermal bridging from the building's structure to the conditioned interior.


Foundation - Super

This is an example of a well-performing, affordable radiant floor & stem wall insulation assembly, and can be used with the Super Wall Insulation assembly above. All interior living spaces are insulated from the building's structural frame, and all insulation is encased in a seamless, weather-resistant coat of amcorite Ferrocement.

Healthy

High IEQ = Healthy & Safe Interiors

High IEQ = Healthy & Safe Interiors

Indoor air quality and VOCs (Volatile organic compounds) are an important concern for the longterm health of you and your family. Ideally, you want products which are:
  • sustainably manufactured
  • long-lasting (low-maintenance & non-degradation in performance)
  • non-petroleum based
  • don't support the growth of mold or mildew
  • don't release toxins at room temperature over the product's lifetime (low-VOCs)
  • don't release toxins in case of a fire (inert)
While it's unlikely any one product will meet all these requirements and be affordable, some come close. You can balance your project's thermal & budgetary requirements by using a combination of healthy & standard products. For example, many of our typical am‑cor insulation assemblies include a combination of safe aerogel thermal breaks and high performance batts or polyiscocyanurate spray foam.
