Firestop Penetrations

Through-penetration firestop systems are designed to restore the hourly rating of fire resistive-assemblies that have been breached due to penetration by electrical, plumbing, or mechanical items.

Said items are vital in modern building construction, which oftentimes requires them to pass through fire-resistive floor or wall assemblies.

To maintain the fire-resistant properties, large openings are cut through the wall or floor, and the penetrating items are installed, leaving an annular space around them.

Various types of fire-resistant materials are then installed within that open space, around the penetrants, to prevent flames and hot gasses from passing through.

All of AFI’s applications are tested by UL Systems and Engineering Judgements.

Fireproofing

Used as a preventative measure to keep steel from reaching a weakening temperature.

Accurate Firestop & Insulation offers Cementitious, Board, and Intumescent Fireproofing applications. Cementitious Fireproofing, the faster application rate of the three, can still be left exposed, but the finish is not as polished.

Board Fireproofing is a dry application form and can be left exposed. The application of Intumescent Fireproofing is aesthetically appealing, while still achieving the necessary, regulated fire rating.

All of AFI’s applications are tested by UL Systems and Engineering Judgements.

Thermal & Acoustic Insulation

Thermal Insulation refers to the materials, methods, or processes used to reduce heat transfer. It helps maintain the temperature by preventing heat from escaping or entering an area, keeping an enclosed area, such as a building, warm, or the inside of a cold area.

When a space is well insulated, it is more energy and cost-efficient by preserving a stable, consistent temperature.

Additionally, most forms of Acoustic Insulation work as a buffer to absorb noise and vibrations coming from outside of the room.

Unlike heating and cooling equipment, insulation does not require maintenance, upkeep, or adjustments regardless of the outside conditions.

AFI offers a variety of insulation installations, including a convenient spray-on method.

Acoustical Sealant & Spray

Used to fill the gap between acoustically rated assemblies or penetrations, most commonly for top-of-wall, bottom-of-wall, and wall-to-wall applications.

This particular sealant is not fire-rated and does not provide any form of fire safety, but is smoke resistant and makes the gaps in conjoined areas more aesthetically appealing.

Acoustical Sealant & Spray also helps to achieve the STC ratings required for Sound and all of AFI’s applications are tested by UL Systems and Engineering Judgements.

K-13

A spray-applied acoustic insulation, typically used as an exposed ceiling finish requiring no additional barriers or materials. K-13 meets project requirements for noise control with an attractive natural texture that is available in standard and custom colors.

The K-13 sound absorption spray system begins with specially prepared cellulose fibers combined with natural fire retardants in a strict, quality-controlled manufacturing process to produce a Class A, Class 1-rated material. K-13 is then spray-applied by an international network of professional contractors licensed by ICC to ensure consistent and predictable results. During application, the K-13 fibers combine with a patented water-based adhesive resulting in a durable, exposed finish.

K13 is a thermal and acoustical insulation.

It’s important to note that while K-13 spray provides thermal and acoustical benefits, it is not intended to be a standalone solution for structural fire protection. Specific fire protection requirements should be addressed separately based on local building codes and regulations.

Expansion Joints

Also known as a ‘Seismic Joint’, is a structural element designed to absorb the dimensional changes and movement that occur within a structure due to various factors such as temperature variations, seismic activity, moisture expansion, or settlement of the building. It is commonly used in buildings and parking structures to accommodate the expansion and contraction.

Expansion Joints can be fire-rated and are installed as required by the Building Code.
