Why choose SIPS for your tiny house?
Let’s start with what they are. SIPS stands for Structural Insulated Panel System. It is a composite building material, typically consisting of a foam core and an OSB skin. SIPS replaces the lumber, sheathing, insulation and vapor barrier of a typical building envelope.
SIPS is not a new building technology, it has been around since the 1930’s. Within the last X number of years the technology has advanced to where it has now become more economically viable than ever to build with SIPS. Combined with homebuyer’s increasing need to conserve energy and precious resources, SIPS are a clear winner in a burgeoning tiny home industry.
The panels we use are comprised of an extruded polystyrene core sandwiched between two sheets of OSB (oriented strand board, a wood product made up of fast growing trees and shrubs once considered waste by the lumber industry). Using this method, fewer trees will be cut down to build your tiny home. Also, the panels are delivered cut to size so there’s significantly less job site waste.
- Energy efficiency:
Properly constructed SIPS building envelopes are vastly more airtight than conventional stick framed buildings. They also have a higher insulating value than typical walls of the same thickness. This helps make them more energy efficient and comfortable – homeowners can expect up to 60% energy savings!
- Mold mildew and pest resistant:
Another benefit of a tighter building envelope is that, structurally speaking, it also helps the home stand up to the elements better. This is because there are no pockets for moisture to collect or pests to nest.
Compared to stick framed tiny homes SIPS-built tiny homes are 20-30% lighter. This means you can go bigger without having to upgrade your trailer or buy a heavy hauler to move the tiny home for you.
- Structural rigidity:
In your traditional tiny home every joint acts as a hinge, which, to a certain degree, causes the structure to twist and rack in high winds during transportation. SIPS-built tiny homes contain as few as twelve joints and thus maintain their structural rigidity even at highway speeds and on rough roads.
- Shorter build time:
Using SIPS we can assemble the building envelope in as little as a day, where as a traditional envelope can take up to two weeks.
