![]() ![]() Many homeowners build from a sketch or rough plans, but when working with SIPs, you need a technical 3D rendering to have it thoroughly planned out beforehand as the SIPs are built and cut to fit the plan. But one thing to keep in mind is that you will have to use an AutoCAD computer program when designing your home. Metal SIPs have drawbacks and can be challenging to work with, but they are used in light commercial construction and home construction in places like Florida because of hurricane resistance. They’re often used by tiny house builders who are looking for something more efficient that traditional framing. Pro: SIPs Have A High Insulation Ratingįirst, as I mentioned before, SIPs have an excellent insulation rating. Let’s expand a little on the pros and cons of SIPs mentioned above. The Pros And Cons Of Building A Tiny House Using SIPsĪside from the incredible efficiency and insulation properties of these tiny house wall panels, SIPs have many other pros as well. The polystyrene acts as a vapor barrier and an air barrier as well as a thermal layer. You don’t have to worry about insulation slumping over time because it’s one solid, rigid piece. Either way, they’re very energy efficient.Īnother benefit is that because prefab SIP panels are bonded in a factory, there are no air gaps. You can go even thicker with SIPs as well, should you desire, just keep in mind that your window sills will be deeper and your interior space will be smaller because of it. The R-values are around 7 per inch, and with SIP panels that are 4 inches thick, that’s an R-rating of 28 - more than double the rating of a traditional wall with studs. ![]() The polystyrene foam is closed cell, making it an excellent insulator that is both high in R Value and rigid in strength.Īs tiny house wall panels, they provide plenty of protection. You then roll the insulation between the studs, but the studs themselves act as a thermal bridge that allows cold and heat to seep into your home.īuilding a tiny house using SIPs, on the other hand, means you’ve got a super-efficient, airtight construction. Wood is a pretty poor insulator, and when you construct a traditional wall, you usually have studs spaced every 16 to 24 inches. Building with SIPs eliminates the need for studs and framing, which results in more efficient walls. They can be challenging to modify after they leave the factory, so designers and builders usually work within the parameters of the standard sizes - like constructing with blocks.įor those who are interested in engineering, SIPs are a fascinating option - a material created by modern technology. Prefab SIPs come in various sizes, but most are between 4×8 feet and 8×24 feet. SIP panels are highly engineered products that are almost always created in a factory setting using machines to apply glue and pressure to bond the SIP together and cure just right. Others may use outer layers of plywood, fiber cement, gypsum, or even metal. Some use other insulators like polyurethane. Now, not all SIPs are made from OSB and polystyrene. These layers are bonded together to create rigid four to 12-inch thick prefabricated panels that make excellent building materials for tiny homes. The “cookie” layer is comprised of OSB (oriented strand board) and the inner “ice cream” layer is made of expanded polystyrene foam. Why? Because that’s exactly what these structural insulated panels look like. I must admit that researching SIPs left me craving an ice cream sandwich.
