FAQ
  • What are the Louisiana Pacific LP (Inner Seal) Siding failures?
    Two types of siding produced since 1985 by Louisiana Pacific, and these are known as "innerseal" siding and comes as lap siding and in panels. Siding of this type tends to absorb moisture and deteriorate prematurely due to a manufacturer's defect. Many homes in the Pacific NW have been sided with this kind of siding, and have not been able to hold up due to the weather and moisture conditions.
  • What is the Louisiana Pacific Innerseal Siding Litigation?
    The Louisiana Pacific Inner-Seal siding is subject of a class action suit which was settled in October, 1995. Visit the official Louisiana-Pacific Inner-Seal Siding Litigation Claims Administration Information Web site for more information.
  • Can I replace my LP siding with vinyl siding?
    No. If you are planning to replace your LP siding, please remember that vinyl siding is not an option under the Diamond Hills HOA covenants.
  • Can I use any color to repaint my house?
    If you are planning to paint your house using something other than the original color, please contact the Architecture Committee before painting.
  • What is the difference between LP (Inner Seal) "Lap" Siding and LP (Inner Seal) "Panel" Siding?
    Louisiana Pacific sold two basic types of LP (Inner Seal) siding, "Lap" or horizontal siding and LP (Inner Seal) "Panel" Siding. Many people refer to the "Panel" Siding as T1-11. This is not a correct reference as T1-11 siding is a true plywood siding and it is made quite differently from the LP (Inner Seal) Siding and has held up better than the older LP Siding.
    Most builders placed either chip board or plywood behind the "Lap" Siding. So, if you take off a piece of "Lap" Siding you have another protective layer of material before you get to the cavity of your wall. The "Panel" Siding is what we call a "single wall construction" type product. If you pull off a piece of panel siding it will immediately open up the cavity of your wall. You will be able to see your wiring, insulation, plumbing etc. This is one of the reasons so many siders suggest siding over the panel siding. By siding over the "Panel" Siding it gives you a second layer of protection. Thus the terms... "single wall construction" (panels only) and "double wall construction" (lap siding followed by a layer of plywood or chipboard). It is not advisable that you side over any panels that are seriously damaged. Usually the most damaged panels can be found in the non-insulated areas of your fireplace chimney or over the garage entrance. Chipboard products are often called "OSB" - oriented strand board.
  • Is it OK to just re-side over the LP panel siding instead of pulling all the panel material off?
    Most siding companies pull off all of the LP lap product and install new hardi-plank or cedar. However, some siding companies re-side over the LP panel siding instead of pulling the panel material off. This process can have cost benefits; but, prior to siding over the panels you should look to see how much damage there is to the panels. If the damage is severe, it is not advisable siding over the panels.
