Choose the Right “Cap” for Your Roof

By: John Myers, Sales Representative – Architectural Products


You wear a cap on your head to keep warm in the cold weather or keep cool in the hot sunny weather, buildings like people need to be protected from the heat and cold as well. This starts at the roof.  The easiest path for heat loss and heat gain. ACH Foam Technologies’ Foam-Control® and Foam-Control Plus+® roof insulations are excellent choices to “cap” a building.

Building codes dictate the minimum amount of R-Value that commercial buildings need to be energy efficient. This R-Value is used in the calculation of other components of the building such as HVAC systems.  Designers and building owners are not investing in these properties and equipment for a short term, but instead are looking to capitalize on their investment over the long term.  Foam-Control® and Foam-Control Plus+® roof insulations help with that investment by offering the only stable long-term R-Values available in roofing market today.

Alternative insulations are subject to R-Value loss over time, as evidenced by LTTR mathematical calculations used by polyisocyanurate insulation. This calculation averages the R-Value over 15 years and publishes the median R-Value rather than the long-term final R-Value.  ACH Foam Technologies has test results that show the R-Value of EPS remains stable after 30 years!

HVAC equipment designed at an overstated R-Value may become underused and less efficient if not designed to a predictable stable R-Value. This causes the equipment to fail prematurely and is a major expense to the building owner. Replacement equipment is likely to be sized as the original, thus repeating the cycle of inefficiency..

ACH Foam Technologies has a variety of “caps” from which to choose to match your climate zone. If you are protecting your building from heat gain or heat loss, Foam-Control® and Foam-Control Plus+® roof insulations are the effective long-term and affordable choices. Designers and building owners need only speak to one of the knowledgeable representatives at ACH Foam Technologies to find out more information. We have independent verification of R-Value field performance that is valuable information when designing your roof’s headwear.

“EPS Saves the Day”

 By: Terry Meier, Sales Representative – Architectural Products

These are the words of Rich Lowe, Structural Manager for W.W.Clyde, at the conclusion of a job using EPS Fabricated foam shapes.

Before the project began, W.W.Clyde sent ACH Foam Technologies a number of detailed drawings showing the shapes of pier columns being used on the South Valley Connector in Portneuf Idaho.

5-11-15 (1)

5-11-15 (4)

To help W.W.Clyde accomplish this task of producing these columns, ACH Foam was able to fabricate EPS into the desired shapes which were then used as a concrete form. The concrete was then poured into the EPS form. Once the concrete dried the EPS foam shape was easily removed leaving a beautifully formed concrete pier column.

The customer indicated that they saved a great deal of time and over $2,600.00 per pier column by using EPS Fabricated foam instead of wood.


Because EPS foam is lightweight, inexpensive and easy to fabricate into just about any shape, it makes it an ideal medium for small or large three dimensional shapes.

ACH Foam Technologies was grateful to be part of this project by providing a service and a product which in the words of our customer “saves the day”.

Geofoam: The Problem Solver

By:  Nick Harvill, Sales Representative, Architectural Products

The Atlanta, Georgia storm water system is tied to the city’s sanitary sewer system. So when heavy rains come down, the system is frequently overwhelmed. As the rainstorm continues, the sewer system begins to fill up, water only being able to leave it as fast as it can be processed by the sewage treatment plant. The City of Atlanta was getting hit with heavy fines for sewage overflow bypassing the plant into the rivers. Sewage was backing up into people’s homes and special valves were being installed to prevent the backflow. More sewage water storage was needed.

The City engineers came up with a plan to build sewage storage vaults around the city. Placed under parking lots and vacant lots, the vaults were to provide millions of gallons of storage each. One vault was being placed under the media parking lot at Turner Field, Home of the Atlanta Braves. As they progressed with the construction, they hit a snag. As part of the project, the parking lot had to be replaced with the pre-existing contours to match the surrounding elevations. One corner of the vault would require about 12 ft of fill and the vault was not designed for that extra weight. It would cost over a quarter million dollars to reinforce it. There was also a hard completion date to meet. They needed another solution.

Nick - Geofoam - July1

They turned to Geofoam and ACH Foam Technologies. Geofoam is a cellular plastic material that is strong but has a very low density. Weighing less about 1% of conventional fill materials, it has enough compressive strength to support the parking lot and the cars that would be parked on it. Geofoam would reduce the load of fill material on the vault at 20% of the cost of modifying the vault. ACH Foam Technologies took the vault design plan and the elevations and created a shop drawing of tapered and square blocks to illustrate where the Geofoam fill is placed.

Nick - Geofoam - July2

ACH Foam Technologies also helped the contractor acquire Hot Wire Cutting tools to do jobsite cutting and shaping modifications. With Geofoam and the assistance of ACH Foam, the job was completed on time.

Geofoam provides solutions to many fill problems. Weight reduction, reducing lateral pressure on foundation walls, and reducing construction time are some of the ways Geofoam solves problems. It comes in seven grades to meet load requirements. While field cutting is usually needed, special cuts and tapering are often provided to reduce the amount of field cutting needed. Shop drawings are provided for placement. We at ACH Foam Technologies are proud to be able to provide solutions with our Geofoam product line.

The Polar Advanatge

Jim Nugent, Regional Sales Manager

The primary function of rigid insulation on a building is to thermally protect the building envelop and provide energy savings and comfort to the occupants. Energy codes and experience are driving the growing of placing insulation on the outside of the building rather than inside the building. The new International Energy Code Conference (IECC) now has new standards for use of continuous insulation on the outside of a structure.

Products with higher vapor permeance like Foam-Control® Plus+® are proving to be ideal for perimeter foundations, under-slab, and cavity walls applications. Foam-Control® Plus+® has shown the characteristic to shed moisture in drying conditions which helps insure long-term R-value retention.  Less permeable insulation products like extruded polystyrene and polyisocyanurate have shown to retain moisture longer which impacts long-term R-value. Rigid insulation is not intended to be a waterproofing product, but in “real world” conditions, exterior insulations will be exposed to moisture.

Architects are starting to design certain wall assemblies where the air, water, vapor and thermal protection are all achieved with the insulation layer on the outside of the structure. In these assemblies a  product like Polar-R®, with low permeability, would be preferred. Polar-R® laminated sheathing is your solution for this application. Polar-R® is a composite of EPS rigid insulation thermally laminated on 2 sides with a film facer. Polar-R® with the appropriate detailing, provides thermal protection in addition to an air and moisture barrier in a single layer.

The versatility of the Polar line of film laminated EPS insulation products extends into the commercial roofing market with Polar Fold® roof recover board. Polar Fold® roof recover board is now the preferred insulation material when rebuilding over an existing roof with a new mechanically attached thermal plastic roof membrane. The lightweight moisture resistant insulation comes in a continuous 4’x50’ sheet (folded every 2’). The facer is specifically designed to be compatible with both TPO and PVC membranes.


Roofing contractors appreciate the lightweight yet very durable insulation and the large sheet that speeds installation and building owners appreciate the cost savings when the existing roof does not need to be removed but but a new roof can be installed directly on top.  The versatility of the Polar line of film laminated EPS products are giving contractors and owners new options to insulate and protect their building.
