Environmental Frequently Asked Questions


FSC® COC Certification

What is FSC?

The Forest Stewardship Council (FSC) promotes environmentally appropriate, socially beneficial, and economically viable management of the world's forests.

Environmentally appropriate forest management ensures that the harvest of timber and non-timber products maintains the forest's biodiversity, productivity and ecological processes.

Socially beneficial forest management helps both local people and society at large to enjoy long term benefits and also provides strong incentives to local people to sustain the forest resources and adhere to long-term management plans.

Economically viable forest management means that forest operations are structured and managed so as to be sufficiently profitable, without generating financial profit at the expense of the forest resources, the ecosystem or affected communities. The tension between the need to generate adequate financial returns and the principles of responsible forest operations can be reduced through efforts to market forest products for their best value.

What is FSC® Chain of Custody (COC)?

FSC® Chain of Custody (COC) is the path taken by raw materials, processed materials and products, from the forest to the consumer, including all successive stages of processing, transformation, manufacturing and distribution.

The main objective of FSC® COC certification is to ensure that FSC certified material is tracked through the supply chain between operations and production processes within operations. Only FSC® COC certified operations are allowed to label products with the FSC trademarks.

A certified Chain of Custody up to the final point of sale enables end customers to identify and choose FSC certified products knowing there is a system in place to verify the sources of the wood used to manufacture the products. The FSC label thus provides the link between responsible production and consumption.

VT chain of custody numbers: SCS-COC-004128 (Holstein-License #: FSC-C005590) and SW-COC-001518 (New Albany-License #: FSC-C018924)

What makes VT doors FSC Chain of Custody (COC) certified?

FSC® COC certified doors are manufactured using FSC certified and FSC Controlled Wood components. These doors are sold by FSC® COC certified manufacturers and distributors. FSC doors hold an “FSC Claim”. These claims are printed on invoices and shipping documentation (Bill of Lading, Packing Slips) on a line by line basis. An example of a FSC claim for a certified door is ‘FSC Mixed 97%’. Also, doors with a FSC claim of 70% and above are eligible for on-product labeling. VT doors with FSC claims meeting this criterion are identifiable with a FSC label reading ‘FSC Mix’ on the door tag.

Is FSC available on Stile and Rail/Profile doors?

Yes. Stile & Rail doors are available from VT’s Artistry and Heritage Collections. All components are available as FSC.

Can VT provide a door with FSC certified core without any additional FSC Certified or controlled wood components?

Yes. However, the door would not have an FSC claim or assist with LEED credits.

What about FSC Veneer Only and when do I need that?

VT doors with FSC Certified veneer only are available. These doors are not eligible to carry an FSC claim. These doors can be specified when there are no LEED requirements or using another green building rating system that does not require a FSC claim for the product.

As a door distributor, do I need FSC® COC Certification if the doors are shipped directly to the job site?

For LEED projects registered after April 2008, distributors must hold a valid FSC® COC certification and invoice doors per FSC requirements to assist a project with LEED for New Construction Materials and Resources (MR) credit 7: Certified Wood. Door distributors who are installing doors on the project are not required to have FSC® COC as they are defined as a project contractor or subcontractor per LEED requirements.

Is FSC Particleboard available?

Yes. FSC particleboard is readily available.

Are agrifiber core doors available with an FSC claim?

Yes. Agrifiber doors are available with FSC claims. These doors are manufactured with agrifiber cores, FSC Certified (Stiles, Rails, Crossband, Veneer), and FSC Controlled Wood (Edges). Agrifiber is a wheat based product and is excluded from FSC claim calculations. These doors carry claims of FSC Mixed 90% and above and contain 30% new wood by weight.

Is Bamboo FSC?

FSC certified Bamboo is available. Bamboo is not required to be FSC certified or FSC Controlled Wood to be used on FSC certified doors as it is not wood, it is a grass.

FSC Controlled Wood


What is the difference between FSC Controlled Wood and FSC certified veneers and when do I use which one?

FSC veneers are veneers that are FSC certified. FSC Controlled Wood veneers are non-FSC certified veneers used in the manufacture of a FSC certified door. FSC COC Certification requires that all non-FSC wood meet their Controlled Wood standards. For more information view Controlled Wood User Guide

FSC Certified veneers should be used for face materials when a door specification states “FSC Certified Veneers”. In most other cases Controlled Wood veneers will meet specifications with FSC requirements.

LEED Green Building Rating System

What is LEED?

LEED (Leadership in Energy and Environmental Design) is a voluntary, consensus-based national rating system for developing high-performance, sustainable buildings.  Developed by U.S. Green Building Council (USGBC), LEED addresses all building types and emphasizes state-of-the-art strategies for sustainable site development, water savings, energy efficiency, materials and resources selection, and indoor environmental quality. LEED is a practical rating tool for green building design and construction that provides immediate and measurable results for building owners and occupants. LEED is the most widely accepted green building system.

LEED Rating Systems Credit Requirements

What is the difference between LEED Silver and Gold and how do I achieve each of them?

LEED has four certification levels; Certified, Silver, Gold and Platinum. The levels are achieved based on the amount of credits earned by a project. The credits do not change for each level of certification. When specifying LEED assistance, individual credit needs must be stated. Listing LEED Gold or LEED Silver is not specific enough to know what credit assistance is needed. See below for LEED NC certification levels.

Certified - 40–49 points
Silver - 50–59 points
Gold - 60–79 points
Platinum - 80 points and above

How are LEED and FSC related?

For LEED green building rating systems, FSC Certified products assist with MR credit 7: Certified Wood. FSC is the only certified wood certification accepted for LEED projects.

MR 4: Recycled Content


What percentage of recycled content do our doors contain?

Recycled percentages vary by door type. Agrifiber cores (70% by weight), Particleboard cores (70% by weight), and HDF crossbanding (20% by weight) are composed of 100% pre-consumer recycled fibers. Standard particleboard and agrifiber doors contain 90% pre-consumer recycled content by weight. Below are door types and recycled content by weight (as related to LEED criteria). For LEED, FSC materials cannot count for both MR 4 and MR 7 credit. FSC Particleboard and FSC HDF crossbanding will be counted as FSC by default.

What % of VT doors are recycled content both by weight and by cost?

VT calculates recycled content by weight to match LEED requirements. This compliant % is then multiplied by the distributor cost of the doors to get the total LEED assistance for a project under LEED credit MR 4.

MR 5: Regional Materials

What are the qualifications for MR Credit 5: Regional Materials?

For LEED for New Construction (most common), Schools, and Core & Shell products must be extracted, harvested or recovered, as well as manufactured, within 500 miles of the project site. A point is available for reaching 10% regional materials, and an additional point (Total of 2 points) for achieving 20% regional materials for the total material cost of a project.

For LEED for Commercial Interiors, 1 point is available if 20% of materials and products used are manufactured (extraction point not needed) within 500 miles. An additional point is available if 10% of materials are extracted, harvested or recovered, as well as manufactured, within 500 miles of the project site

What cores assistance with MR 5 credit?

Several cores qualify for regional material credit. Click below for list of extraction locations.

EQ 4.4: No Added Urea Formaldehyde (NAUF)


What does NAUF mean?

NAUF is short for “No Added Urea Formaldehyde”

Does VT have a NAUF only product available (without FSC)?

Yes. All door types are available as NAUF without FSC. The only doors types not available as NAUF are 5540H, 5P40H, 1240H, and 1P40H.

Does VT offer any “formaldehyde free” door options?

No. We offer no added urea-formaldehyde options. A formaldehyde free wood product is not possible, as formaldehyde is naturally emitted from wood.

Most green building programs specify no added urea-formaldehyde composite wood, agrifiber and laminating adhesives. This means that no urea-formaldehyde binder resins were used in the production of composite wood (particleboard, MDF, SCL, Stave etc.) and agrifiber products, and also not present in the adhesives used to manufacture the final assembled product.



Where will I find LEED requirements in the specifications?

LEED credit requirements should be written into the wood door section of the specification. Each LEED credit should be spelled out in these sections. If not, Section 1 may hold the LEED requirements. Either of these sections should have a LEED specific reference.



How do I fill out the LEED paperwork?

VT quotes, acknowledgements, and invoices state LEED credit assistance for each door type quoted, ordered, or supplied. These percentages can be used to complete forms needed for LEED projects. Most forms are generic and not door specific, so additional credits may be listed that are not applicable to VT doors. Label these sections as Not Applicable and move on. Many times a separate form must be filled out for each door type used on a project, as each door type may assist with different credits or percentages. Distributors must also supply costs associated for each door type for proper credit calculations. All forms are different, fill the forms based on provided VT information and submit VT’s letter as backup documentation.

What do I list if the form asks for weight?

VT calculates all weight percentages for you. If a form asks for these amounts, list the compliant % provided by VT. No need to break down the components, as you supplied the % for the entire door. The supplied manufacturer documentation meets all submission requirements for a LEED project.

Can VT doors assist with EQ 4.1, 4.2, 4.3?

These credits are not applicable to factory finished wood doors. EQ 4.1 and EQ 4.2 are requirements for adhesives, sealants, paints, and coatings “used on the interior of a building (i.e. inside of the weatherproofing system and applied on-site).” EQ 4.3 applies to flooring systems. These are often included because forms are not product specific.

What if they require a Binder Type?

EQ 4.4 requires composite wood, agrifiber, and laminating adhesives contain no added urea-formaldehyde resins. Compliance with this credit does not require the resin type used or VOC content. A letter from the manufacturer stating the composite wood, agrifiber, and laminating adhesives is the only documentation required.

Does one manufacturer have more LEED credits than another one?

All door manufacturers can assist with the same LEED credits. The amount of assistance can vary based on the construction of the doors. The thickness and width of the core, crossband, stiles, rails, faces, and edges has an effect on the compliant percentages because of the weight differences. These differences are often very slight.

Also the location of manufacture and source of materials can affect the amount of regional material available. For example, a door manufacturer located in the western US, may be able to supply MR 5 credit for customers in this region, while a manufacturer in the Midwest or East may not be able supply credit assistance.

Manufacturers may use rapidly renewable materials, such as agrifiber, and another may not offer such materials for door manufacture.

For FSC doors, one manufacturer may use higher amounts of FSC certified material, while another may use higher amounts of FSC Controlled Wood materials. Every manufacturer is going to have differences that will affect the amount of LEED credit assistance.



Does AWI QCP give me any credit towards LEED?

There is not a specific LEED credit associated with AWI QCP. Doors that are manufactured to meet AWI QCP specification may qualify for LEED credit assistance.
