Frequently Asked Questions

What is the STC rating of this door, and how is it measured?

This door achieves an STC rating of 35 when tested according to ASTM E90 standards, measured in a laboratory setting with standard frame and perimeter seals. The rating reflects reduction in sound transmission for frequencies between 125 Hz and 4000 Hz, covering typical speech, television, and household noise.

Can the door be customized to match existing wood tones in my home?

Yes, the door is supplied pre-primed for on-site painting or staining to match any existing wood finish. For factory-applied lacquer, we offer custom color matching based on a physical sample or RAL code provided by the buyer, with a lead time extension of 5 working days.

Is this door suitable for use in a home theater with high sound levels?

For home theaters with peak sound levels above 85 dB, we recommend upgrading to our acoustic package with double perimeter seals and a sweep at the door bottom, which raises the STC rating to 40. This modification reduces bass frequency transmission more effectively than the standard configuration.

How do I order a non-standard size for an existing door frame?

Provide the exact width and height of your frame opening, along with the desired swing direction (left or right). We manufacture to your dimensions within the maximum size limit of 1200mm x 2400mm, and the door is pre-drilled for hinges and lock preparation based on your hardware specifications.

What is the lead time for custom-sized orders, and how are they shipped?

Custom-sized orders require 20-25 working days from order confirmation. Each door is individually crated in a wooden box with foam padding and corner protectors. Shipping is via sea freight FOB China, with typical transit times of 25-35 days to North American or European ports.
