As container houses continue to gain popularity in both residential and commercial construction, interior material choices have become increasingly important. Among the most practical and aesthetic wall finishes is the SPC wall panel (Stone Plastic Composite). But how do you choose the right one?
In this article, we’ll guide you through the key factors to consider when selecting SPC wall panels specifically for container homes.
What Is an SPC Wall Panel?
SPC (Stone Plastic Composite) wall panels are made from a combination of limestone powder, PVC, and stabilizers. They are:
-
Waterproof & moisture-resistant
-
Fire-retardant
-
Durable and impact-resistant
-
Eco-friendly and formaldehyde-free
-
Easy to install and maintain
All these make SPC panels ideal for compact, high-efficiency structures like container houses.
Key Factors to Consider
1. Panel Thickness
Common thicknesses range from 3mm to 7mm:
-
3–4mm: Saves space, ideal for small interiors
-
5–6mm: Balanced choice; durable yet space-efficient
-
7mm+: Better for insulation and soundproofing (e.g., office or studio containers)
💡 Recommendation: 5mm is typically the sweet spot for container homes.
2. Fire Rating
Safety is crucial in a metal-structured home. Look for SPC panels with:
-
At least B1 fire rating (flame-retardant)
-
A-class fire resistance if extra protection is required
3. Environmental Standards
Because container houses are often used as living or working spaces, indoor air quality matters. Ensure the SPC panels are:
-
Formaldehyde-free
-
Certified (SGS, CE, ISO, etc.)
4. Installation Method
SPC panels come in various installation formats:
-
Click-lock system: Quick and tool-free assembly
-
Glue-down: Offers strong adhesion, best for flat surfaces
-
Keel-mounted (frame-based): Ideal for structural strength and long-term use
💡 Tip: Use click-lock or keel-mounted systems for easier maintenance in container spaces.
5. Design & Color
With limited space, visual impact matters:
-
Light colors (e.g., white, beige, light gray) make interiors feel more spacious
-
Wood grain or stone textures can enhance aesthetics in commercial settings
6. Price vs. Brand
Prices range from $7–$20 per square meter depending on quality. Stick with reputable brands that offer:
-
Product warranties
-
Certifications
-
Customer support
Examples: LG Hausys, DÖRF, or local certified SPC manufacturers.
