Flat Roofing Insulation

As of June 23, 2008, we now offer our customers a choice of using Recycled on New Poly-Iso insulation.

Benefits of using recycled insulation include instant and continuous financial benefits. Since we get recycled ISO board at a discount we pass on the savings to you, and with more insulation for the same amount of money you would spend on a new ISO, you will continue to save money on your energy costs year round.

But that’s not all! Although ISO insulation is not “green” per-se, using recycled insulation is a green choice since by reducing your energy consumption, it will also reduce carbon monoxide emitted into the atmosphere. It will also not go into our nation’s land-fills, therefore it will benefit the environment.

Types of insulation we use:

By default we use a 1/2 inch fan-fold Styrofoam insulation, which is mostly used when there is already some insulation on the roof. Fan-fold insulation comes with 2-R value, so it will add some insulating value to the roof. It also acts as a separation barrier between the deck or old roofing material and IB membrane. Fanfold insulation is attached with heavy-duty screws and corrosion-resistant insulation plates. It is light-weight, features quick installation and is ideal for a roof layover. It is also the most economical option.

As an option you may choose to use a common ‘new-construction’ and complete roof replacement choice of insulation – Poly ISO board, which comes in a wide range of sizes and features high R-values from 3 to 20-R. Sizes include 1/2, 1, 1.5, 2, 2.5, 3 and 3.3 inches and R-value is calculated using 6-R per 1 inch of insulation.

If drainage is a concern, ISO insulation comes in tapered design which has different thicknesses at each end, and is used to create pitch ( slope ) on a completely flat roof. Slope is usually directed toward drains or drip edges and diverts the water flow to where it can exit the roof.
