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 and what is its purpose?
The blue film is a 0.04mm PE (polyethylene) moisture barrier laminated onto the EVA foam. Its distinctive blue color makes it easy for installers to visually confirm correct placement, seam alignment, and overlap during installation—eliminating guesswork and reducing costly mistakes.
Q
What types of flooring is this 3mm EVA underlay compatible with?
This EVA underlay is suitable for use with laminate, hardwood, and bamboo flooring. Its density and thickness provide reliable support and cushioning across all three flooring types, making it a versatile choice for residential and commercial applications.
Q
What are the IIC and STC ratings, and why do they matter?
The IIC (Impact Insulation Class) rating of 73dB measures how well the underlay reduces impact noise such as footsteps, while the STC (Sound Transmission Class) rating of 72dB measures its ability to block airborne sounds. Both ratings are high, indicating excellent acoustic performance for noise-sensitive environments.
Q
How does this EVA underlay perform in terms of moisture resistance?
With a water absorption rate of less than 0.1%, this EVA underlay offers excellent moisture resistance. The integrated blue PE film acts as an additional vapor barrier, protecting your flooring from subfloor moisture and helping to extend the lifespan of your floor installation.
Q
What container load quantities are available for bulk orders?
For a 20GP container, the load quantity is approximately 8,000 sqm (86,000 sq.ft). For a 40HC container, the capacity increases to approximately 18,000 sqm (195,000 sq.ft), making it highly efficient for large-scale flooring projects and international wholesale purchasing.
Q
What packaging options are available for this EVA underlay?
This product is available in three packaging options: Nude (unpackaged rolls), Pallet, and Carton. The choice of packaging depends on your shipping requirements and storage preferences. Each roll covers either 100 sq.ft or 200 sq.ft, offering flexibility for projects of different scales.
