Visible Installation, Comprehensive Protection: Blue Film EVA Underlay
In the world of flooring installation, the most costly expenses often stem from invisible mistakes—a misaligned seam, an accidental uneven overlap, an imperceptible tiny gap.
These overlooked details will gradually surface over the years: squeaking noises, local bulges, edge deformation—all are cumulative consequences of minor installation oversights. Traditional underlays hide all these beneath their monochromatic surfaces, remaining undetected until problems arise. We are determined to change this passive protection model, thus creating the blue film EVA underlay—making the protection process visible and ensuring perfect results from the very start.
Frequently Asked Questions
Q
What is the blue film on the EVA underlay for?
The blue PE film (0.04mm) acts as a moisture barrier and a visual installation guide. It makes seam alignment and overlap positions clearly visible during installation, helping prevent common errors such as misaligned joints or uneven overlaps.
Q
What types of flooring is this EVA underlay compatible with?
This 3mm EVA underlay is suitable for use under laminate, hardwood, and bamboo flooring. Its cushioning and thermal insulation properties make it a versatile choice for various residential and commercial flooring projects.
Q
What are the IIC and STC ratings of this underlay?
The EVA 30-4 model achieves an IIC (Impact Insulation Class) rating of 73dB and an STC (Sound Transmission Class) rating of 72dB, providing excellent sound reduction for both impact noise and airborne sound transmission.
Q
How is this EVA underlay packaged and what sizes are available?
The underlay is available in roll sizes of 100 sq.ft and 200 sq.ft per roll. It can be packaged nude (unboxed), on a pallet, or in a carton, depending on your shipping and storage requirements.
Q
What is the water absorption rate of this EVA underlay?
The water absorption rate is less than 0.1%, making it highly resistant to moisture. This low absorption rate helps protect your flooring from moisture-related damage such as warping, mold, and swelling over time.
Q
How much product can be loaded into a shipping container?
