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
Q1
What is the blue film on the EVA underlay for?
The 0.04mm blue PE film serves as a visible moisture barrier and installation guide. It allows installers to clearly see seam alignment, overlaps, and coverage during the flooring installation process, helping to prevent common mistakes such as gaps or uneven joints before they become permanent problems.
Q2
What types of flooring is this EVA underlay compatible with?
This 3mm EVA underlay (Model EVA 30-4) is specifically designed for use with laminate, hardwood, and bamboo flooring. Its density and thickness make it an ideal choice for floating floor installations across all three flooring types.
Q3
What are the IIC and STC ratings, and why do they matter?
The IIC (Impact Insulation Class) rating of 73db measures the underlay's ability to reduce impact noise such as footsteps, while the STC (Sound Transmission Class) rating of 72db indicates its effectiveness at blocking airborne sound. Both ratings are industry-leading figures, making this underlay an excellent solution for multi-story buildings and noise-sensitive environments.
Q4
What is the water absorption rate and does this underlay provide moisture protection?
The water absorption rate is less than 0.1%, which is exceptionally low. Combined with the integrated blue PE film layer, this underlay provides reliable moisture protection for your subfloor and flooring, making it suitable for installation in kitchens, basements, and other areas with potential humidity concerns.
Q5
How is the product packaged and what roll sizes are available?
The EVA underlay is available in roll sizes of 100 sq.ft and 200 sq.ft. Packaging options include nude (unpackaged), pallet, or carton to suit different shipping and storage requirements. For large commercial orders, a 20GP container holds up to 8,000 sqm (86,000 sq.ft), and a 40HC container can accommodate up to 18,000 sqm (195,000 sq.ft).
Q6
What is the thermal insulation value of this EVA underlay?
The thermal insulation coefficient of this underlay is 0.04 W/mk. This low thermal conductivity value means the underlay effectively retains heat underfoot, contributing to a warmer floor surface and improved energy efficiency in residential and commercial settings.
