Create Energy-Efficient and Durable Block-Outs with AmBuck™

The AmBuck™ Insulated Block-Out System is a stay-in-place buck formwork designed for creating window and door openings in Insulated Concrete Form (ICF) construction. It replaces traditional wood and vinyl block-outs with a more energy-efficient and durable solution that integrates seamlessly with ICF structures. AmBuck™ provides long-term thermal resistance, prevents thermal bridging, and ensures a faster, more reliable installation process.

Advantages of AmBuck™

  • A fully insulated buck system that offers stable, long term thermal resistance that surpasses typical wood or vinyl bucks.
  • Prevents warping, checking, cupping, bowing, rotting, and splitting from occurring, that is seen in most conventional wood-based block-out systems.
  • Long-life expectancy equal to that of the ICF.
  • Integrated insulation, preventing thermal bridging and gaps.
  • Lightweight, fast and easy assembly.
  • Does not contain organic materials, preventing rot and mold growth.
  • Each panel is easy to handle due to the low weight.
  • Equipped with integrated webs that support the swift installation of doors and windows at the face and edges of the panel.

Why Build with AmBuck™?

Superior Energy Efficiency

AmBuck™ Insulated Block-Out System prevents thermal bridging at windows and doors, significantly enhancing the overall thermal performance of ICF walls. This results in lower energy needs and a more sustainable building envelope.

Cost-Effective Solution

By eliminating the need for wood or vinyl block-outs, AmBuck™ reduces material costs and speeds up construction timelines. Its long-lasting, energy-efficient properties also result in long-term cost savings for building owners.

Fast & Easy Installation

With its lightweight panels and simple design, AmBuck™ can be installed quickly and efficiently. Integrated attachment points and webs allow for fast and secure placement of windows and doors, reducing labor time on site.

Long-Term Durability

The EPS panels in AmBuck™ are designed to last as long as the ICF structure itself. They resist issues like rot, warping, and mold growth, making them a durable, low-maintenance choice for both residential and commercial projects.

Why AmBuck™ is the Right Choice

Why ICF? Developers

Developers

Cost-effective, energy-efficient, and eco-friendly EPS materials help developers meet efficiency targets while reducing overall project costs.

Contractors & Installers

Lightweight panels are easy to handle and install, reducing on-site labor time. Complete projects faster and more efficiently.

Architects & Engineers

Integrates seamlessly with Amvic™ ICF walls, allowing for consistent thermal protection that meets stringent energy codes.

Homeowners

Provides superior insulation for window and door openings, reducing energy loss and utility needs.

Green Building with Alleguard

Amvic™ ICF, Amdeck, and AmBuck™ blocks are an excellent alternative for environmentally friendly and long-lasting buildings. There are several elements that make Alleguard’s ICF products a preferred choice for sustainable construction.

Reduces harmful emissions

Alleguard manufacturing facilities use steam and cold water to produce ICF. No harmful chemicals like CFC’s, HCFC’s, formaldehyde are used in Alleguard’s manufacturing process eliminating off-gassing and greatly reducing harmful emissions.

Minimizes waste

Amvic™ ICF can generate as little as 1% construction waste, greatly reducing landfill bound waste.

Uses recycled materials

Amvic™ ICF webs are manufactured using 100% post-industrial recycled polypropylene which effectively means that over 60% of the weight of an Amvic™ ICF block is comprised of recycled materials.

Contributes to LEED® certification

The USGBC’s LEED® Certification program provides a framework for assessing building performance and sustainability based on water savings, energy efficiency, materials selection and indoor environmental quality. Amvic™ ICF may contribute to 32-35 points towards LEED® certification.
