Frequently Asked Questions
What are Murus SIPs?
Murus Structural Insulated Panels (SIPs) are high-performance building panels made with an insulated foam core sandwiched between two structural skins. They provide superior energy efficiency, faster construction, and increased structural integrity compared to traditional building methods.
What applications are Murus SIPs used for?
Murus SIPs are used in exterior walls, roofs, and floors for residential and light commercial construction. They offer an energy-efficient and structurally sound alternative to conventional framing.
How do Murus SIPs improve energy efficiency?
Murus SIPs provide continuous insulation with higher R-values per inch, reducing thermal bridging and minimizing air infiltration. This leads to lower heating and cooling costs and improved indoor comfort.
What types of foam cores are available?
Murus SIPs come with three types of foam cores:
- Polyurethane (PUR) Core – Highest R-value per inch, offering superior insulation.
- Expanded Polystyrene (EPS) Core – Cost-effective and energy-efficient.
- Graphite Polystyrene (GPS) Core – Enhanced with BASF’s NEOPOR® technology for a 20% better R-value than standard EPS.
How does the Murus patented Cam-Lock System work?
The Cam-Lock System speeds up installation by securely locking SIPs together along the tongue-and-groove edges. This ensures an airtight seal, reducing energy loss and moisture infiltration.
Are Murus SIPs environmentally friendly?
Yes! Murus SIPs are LEED-qualified, made without CFCs, HCFCs, or other ozone-depleting compounds. They are a sustainable building solution with FSC-certified OSB skins available.
Are Murus SIPs faster to install than traditional framing?
Yes! The precision factory pre-cutting and Cam-Lock System significantly reduce installation time, making SIPs faster to install than conventional stick-frame construction.
Can electrical wiring be installed in Murus SIPs?
Yes. Murus SIPs come with built-in electrical chases for easy wiring integration, with additional chase locations available as needed.
How fire-resistant are Murus SIPs?
Murus SIPs have a Class 1 fire resistance rating—the highest rating available for combustible materials.
Do Murus SIPs come with a warranty?
Yes.
- Polyurethane SIPs – Lifetime warranty against delamination.
- EPS & GPS SIPs – Limited 10-year warranty against delamination.
How do Murus SIPs compare to traditional construction in terms of durability?
Murus SIPs are stronger and more durable due to their composite construction and proprietary bonding process, offering better structural integrity than traditional stick-frame walls.
