To illustrate this, the Department of Energy’s Oak Ridge National Laboratory (ORNL) tested the performance of large section wall assemblies. The resulting whole-wall R-value data revealed that a 4-inch SIP wall rated at R-14 outperformed a 2×6-inch wall with R-19 fiberglass insulation. The whole-wall R-value was R-21 for a 6-inch SIP wall or 96% higher than the whole-wall R-value of R-11 for the 2×6-inch wall using theoretically R-19 fiberglass insulation. ORNL also tested a SIPs structure side by side with a conventional 2×4 structure to evaluate air leakage.
thoughts on “What Are SIPs (Structural Insulated Panels)?”
Also in Chile, La Dacha Mountain Hut builds its entire perimeter with SIPs 21 centimeters thick, providing a lightweight solution for remote construction while ensuring optimal thermal insulation. The panels form continuous walls around much of the volume and are clad with burnt pine boards (shou sugi ban) on the outside. Used as the shell of custom homes for more than 50 years, Premier SIPS roofs, walls, and floors create superior homes across North America.
How are SIPs Used in Residential and Commercial Construction?
With minimal thermal interference from the air outside, indoor air in SIPs buildings maintains the desired temperature for longer, which reduces the need for the AC. Being an excellent thermal insulator is largely due to the included insulating foam core, an airtight construction, and an energy-conserving ventilation system. By considering these factors during the SIP house design process, you can create a well-planned and functional home that meets your specific needs while maximizing energy efficiency and sustainability. Welcome to this comprehensive guide on designing a SIP (Structural Insulated Panel) house.

They also use significantly less energy during the manufacturing process compared to traditional construction methods and have lower embodied energy than traditional construction materials, such as steel, concrete and masonry. Externally wrapped with black quadroline metal panels, Cristián Romero Valente's WV House is composed of a metal structure that forms its walls and ceilings. To provide thermal insulation, an interior skin and SIPs have been added to the exterior, eliminating thermal bridges and incorporating a high-performance heat recovery ventilation system.

Thinking about a bespoke project?We can help!
One of the unique benefits of SIPs structures stems from the fact that they don’t need roof trusses. This means you have the option to convert the space under the roof into a habitable living space. So if you have a three-bedroom home, for instance, you can easily turn it into a five-bedroom house without having to construct another room. If you are already working with an architect, they can help you determine the right panel thickness to balance cost and energy efficiency. SIP panels used as flooring is typically the final step in creating a tight seal and energy efficient home. Incorporating SIP panels in the walls of your home can create unparralleled air tightness.

SIPs panels are also delivered to the job site with door openings and pre-cut windows, meaning you won’t need to frame out openings on site. Additionally, SIPs structures don’t require bricklayers to build the inner leaf of a structure – a common process with conventional building systems. SIPs structures can withstand harsh weather conditions and extreme climates because when complete, they form a monolithic shell that is seven times stronger than traditional timber frame structures. Beyond providing great structural strength, the monolithic shell gives buildings a solid and robust feel and makes them less susceptible to shifting.
How To Design A SIP House
It is essentially a spin-off of ply-wood sheathing and has been engineered for maximum strength and durability by cautiously orienting the strands of lumber rather than pressing them randomly. Even if you don’t need to change the design and/or features of your building, chances are you’ll need to renovate several years down the line due to normal wear and tear caused by things like moisture or pest damage. Unfortunately, the possibilities in this regard are usually limited in SIPs buildings, and the few structural changes you can make will likely be costly. Such limitations mean that you have to get your building’s design and features right during the planning phase. This is rarely the case because property owners’ needs often change with time, calling for structural tweaks.
This high mechanical resistance is achieved by adhering the panel's different components with polyurethane emulsion. In addition, each panel can include cavities for the passage of installations and other ducts. Thanks to prefabrication, it is estimated that the use of SIPs can reduce construction times by more than 50% compared to traditional methods, also eliminating a large amount of waste typical of on-site construction. SIPs are the simple way to build high-performance structures that meet or exceed building requirements and energy codes.
Therefore, when you build a structure with SIPs, there are far fewer “bridges” allowing the heat to penetrate or escape. So just to clarify, we are not talking about a “sip” out of a drink, we are talking about Structural Insulated Panels. A paneling system that can be installed in your structure that helps save time on construction, money on utilities, and can drastically reduce your carbon emissions. While the airtightness of SIPs is great for insulation, it can compromise ventilation, especially in buildings made entirely of this material. Since SIPs structures come prefabricated, it’s easier to estimate the total cost of any given project. Everything is customized to each project’s specific dimensions and design requirements, making it easier to know beforehand how much of the material you’ll need so you can budget ahead.
SIPs are precisely manufactured under factory controlled conditions and fit nearly any building design. Since the panels are fabricated off-site, they can be quickly assembled on-site, reducing labor requirements and construction time. This not only saves costs but also allows homeowners to move into their new homes sooner. Moreover, SIP construction produces less construction waste compared to traditional methods, making it an environmentally-friendly choice. The panels consist of an insulating foam core sandwiched between two structural facings, typically oriented strand board (OSB).
