Over the years we have invested a lot of time and put thought into different types of wall finishes for our timber frame homes. Visiting our shop will give you the opportunity to see a score of different wall finishes and applications of a dozen materials. Many of our clients utilize gypsum board (sheet rock or drywall) as the interior wall material. (½” gypsum board used in conjunction with a structural insulated panel (SIP) meets the residential fire code for burn rating) Regardless of whether or not you use SIPs , infill walls, or a built up wall system for enclosing your timber frame there are many types of substrates that can be utilized, some of the most common are: ½” cement board, 2 layers of ¼” tile backer board (Hardi-plank), ½” gypsum board, metal (or wood) lathe with lime based plaster and 5/8” gypsum board (Fire rock).
Plastering over these various substrates ranges from a simple sanded mud coat to more complex systems like clay plaster. We have utilized American Clay Plaster on our projects in recent years and have found it to be a fantastic product. Due to the high levels of interest and demand for clay plaster in our homes and projects Trillium Dell regularly offers workshops in clay plaster work, and has a plasterer on staff skilled in the application of this product. One of our favorite features of American Clay plaster is that the pigment is in the plaster itself, so scratches don’t show up as they do in a conventional system of sheetrock and joint compound, there is also an inherent depth and beauty to clay walls that is simply not achievable using gypsum or lime based products.
In some cases our clients choose to infill their walls with a mixture of straw clay, or in the case of straw bale homes stucco over the straw. In these cases American Clay is a natural choice for the finish. The range of pigments and textures available are stunning and lend themselves well to rounded shapes and live edge work. We often incorporate live edge or free form timbers in our timber frame homes; these found timber shapes are carefully scribed together by our carpenters. Once the timber frame is complete the utilization clay plaster to work around these found shapes and curves is much simpler than conventional gypsum based products that have less workability and much shorter set up times. Whatever your choice of products clay, lime, or conventional methods Trillium Dell has the knowledge and experience to help you make the most appropriate decision for your project.
