Interior MDF Shiplap and Tongue & Groove Planks - Both Nickel Gap & V-Groove.
The Best Alternative to Dry Wall To Make Your Cottage Look Good.

Due to their expandability and flexibility, MDF Planks are the perfect alternative to drywall in building a Muskoka or Coastal Cottage. In extreme weather, drywall tends to expand, contract and separate, while Planks will move, allowing for expansion and contraction through summer and winter. The interlocked tongue and groove combined with the ½” or ⅝” thickness is more than enough to keep these planks from sagging. These Planks or Wallboards have been designed to replace drywall. If the drywall is existing, you may want to consider thinner "Shiplap Planks" as they can be fastened or glued. Sagging will not be an issue.  Save on the Cost of Drywall Taping, Mudding, and Priming!
They look great on walls, the sides of staircases, and ceilings. The advantage of using MDF is that there are no cracks and knots to bleed through the paint. These Planks, or the Shiplap version, are often used for wainscoting and included in our Beadboard / Wainscoting Kits.

Our MDF V-Groove Planks have a deep "V" groove often found only in tongue and grooved planks ¾” thick. We not only made the "V" groove deeper, but we made the "tongue" thinner. While other manufacturers may have problems shipping a profile this delicate, our many years of experience in shipping nationwide have taught us how.
You have several options when it comes to exposed joints, bevel the ends or stager the planks, just like hardwood flooring. Adding some Ceiling Beams is another way to hide seams. This not only hides the seams but adds a unique architectural detail.  Tips on installing interior T&G Mouldings.
