FAQs
Is your foam made with ozone depleting agents?
No. The foam is a polyisocyanurate based product. Like most self-foaming plastics, a blowing agent is used to create the bubbles. This agent is in liquid form, but when exposed to the other agents in the foam mixture, becomes a gas and creates bubbles. Many older self-foaming plastics use Chlorofluorocarbons, or CFC’s, in their blowing agents. These chemicals are believed to deplete the ozone layer when released into the atmosphere. However, IPS uses newer blowing agents that have more environmentally friendly non-CFC ingredients.
I’ve heard that polyisocyanurate foam loses its insulation value (R-value) over time. Is that true?
Not for IPS panels, but in general, yes. The reason is that the gases in the foam placed there by the blowing agent are heavy, inert gasses that convect poorly, adding to the insulation value of the product. However, in un-faced foams these gasses leak out and are replaced with air, which convects much easier. The result is a loss in insulation value. However, the dual steel skins on IPS panels trap the gasses in place. Therefore, the insulation value does not fall.
How do I know which skin gauge to use for my project?
This is a decision for your design professional. Thicker gauges, which are lower numerically, are stronger than thinner gauges. However, it is pointless and costly to use a thicker gauge if it is not required for structural or functional reasons. A design professional should optimize the structure and panel gauge to obtain a least-cost solution for your project. The more skin options there are, the easier this is to do.
Will the panels provide a continuous air barrier?
Generally, yes. Continuous air barriers (CABs) are becoming required in more and more building energy efficiency codes. The purpose of a CAB is to cut energy losses in the building due to air leaking in or out. Although CAB requirements vary from code to code, IPS panels meet the requirements for the most common ones.
What R-value are the panels?
The actual R-values are primarily a function of the panel profile and foam thickness. Because there are so many options, it is advisable to consult the technical information for each individual panel. However, a general rule of thumb is 7.14 times the panel thickness.
What information is needed to receive an estimate from IPS?
IPS does not publish a price list but is always willing to quote prices over the phone, by fax or email. For the best possible price, it is always a good idea to provide as much information as possible. Name the panel profile, gauge of the skins and overall thickness. Be sure to mention required thermal ratings, fire testing, wind uplift testing, paint finishes and any performance data that may be listed in the project specifications. IPS can provide unit prices for the panels and hardware or a lump sum price on a project, which will include a complete set of shop drawings.
Can I use my typical trim?
In many cases, yes. IPS can provide standard details showing the recommended method for treating various conditions on a given building. The shape of the trim items can vary. However, the connection points of the trim should be consistent with the IPS standard shapes. We will gladly review your trim shapes for compliance with our standards.
Can IPS provide the clips, fasteners, and other hardware that is needed for my project?
Yes. An IPS lump sum quote will include these items. If a cut list is provided for the project, IPS will provide the items requested by the customer.
What is the typical lead time for providing materials?
The typical note on a lump sum quotation states 4 to 6 weeks after receipt of approved drawings, color selection and/or credit approval. Alternate methods of payment and a provided cut list will sometimes shorten the delivery time. We recommend contacting one of our sales representatives for a projected delivery date.
What are the spanning capabilities of the panels?
Insulated metal panels typically offer very good spanning capabilities because of the chemical bond between the foam and the metal skins. The thickness of the metal skin and insulation can vary and there are many combinations for each panel profile. Please refer to the load tables in our CAD Library or contact an IPS sales representative for complete information.
How heavy are the panels?
The overall size of the panel includes the gauge of the metal skins, along with the insulation thickness, dictates the panel weight. It can vary from slightly over two pounds to almost four pounds per square foot without the addition of any specialty coatings that can be provided by IPS. For handling considerations, it is always wise to consider the total weight of a panel before placing an order. An IPS sales representative can provide this information.
Do IPS panels have fire ratings?
Yes and no. The panels do not provide a one, two or three hour fire rating due to the fact they are comprised of a foam plastic core that will burn. The panels have a Class 1 fire rating which basically means they will burn at a controlled rate that can help contain a fire. They have also been tested for and received excellent flame spread and smoke development values. In addition, the products qualify for a Class A fire rating.
What’s the difference between Stucco Embossed and the Synthetic Stucco Coatings offered by IPS?
The stucco-embossed pattern provided in IPS panels is a physical impression in the metal that is designed to simulate a stucco appearance. The Textured Finish and NaturalStone products are synthetic stucco coatings that are spray applied to the surface of the metal, resulting in a stucco-like appearance.
Why does the panel surface look “wavy” in certain light?
A certain amount of waviness, called “oil canning” is inherent in any product made from coiled sheet metal. Any flat area has the potential for oil canning. Viewing the panels from certain directions and under certain light can reveal stress in the metal known as oil canning. The appearance of waviness, or oil canning, can be caused by the use of lighter gauges, dark colors and framing conditions. Oil canning is cosmetic only and does not affect the structural integrity of the panel and is not cause for rejection.
I’ve seen what appears to be “bubbles” in the face of some panels at different times of the day. What causes this condition?
“Blisters” can sometimes occur when the exterior face of the panel is exposed to the sun. This condition is caused by the thermal expansion of the blowing agent trapped under the panel face and is a common phenomenon of foamed-in-place panels. Blisters are easily repaired and are not cause for product rejection.
