"I have known about Walco and they have worked with me for over 30 years. I have always considered them the go-to company when I needed information or help with any of their products. I’ve received same or next day in person delivery of product data, samples, technical information and if that was not available, advice on other or similar products that might solve my problem, not to mention contact data for manufacturer’s reps.

Frequently Asked Questions

Your Contractor Questions, Answered

Can you help me spec my project?

Yes, we are happy to assist. Please contact, and request Job Specific Questionnaire to get started.

What is the solar heat gain on your skylights?

Solar heat gain varies with the type of skylight you order. Heat gain depends on the type of skylight that is ordered as well as the lens material and glazing. We can help you determine the appropriate choices for your building project.

When it comes to roofing, what are the differences between TPO vs PVC roofing membranes?

The main difference is cost: TPO membranes are less expensive than PVC membranes, and they’re also more eco-friendly. On the other hand, PVC is somewhat more durable and easier to install.

What is the thermal resistance value Oklahoma needs to design for?

Currently, Oklahoma uses the 2015 IBC Building Code which requires R-20 but more people are designing to R-25 standards. Although Arkansas uses the 2012 Building Code, the same standards are advisable in both states.
