Specifying a rug for a commercial or high-end residential project is not the same as selecting one from a showroom floor. Architects working within formal construction documentation need rug specification sheets that satisfy the same rigor applied to any other finish material in the project. This guide covers what those sheets should contain, how they integrate into construction documents, and how to request them from manufacturers.
Where Rugs Sit in Construction Documents
Area rugs and custom carpets fall under CSI Division 12: Furnishings, specifically Section 12 48 00 (Rugs and Mats). In some project structures, particularly hospitality and institutional work, they may also appear under Division 09 (Finishes) if they are being treated as a floor finish rather than a furnishing. The classification matters because it determines where the specification lives in the project manual and who is responsible for procurement.
For most architectural projects specifying Kapetto products, Division 12 is the correct home. The specification should be written in three-part format (General, Products, Execution) consistent with CSI MasterFormat standards.
What a Rug Specification Sheet Must Include
A complete specification sheet for an area rug should contain the following categories of information. If your current vendor cannot provide all of these, that is a signal to find a vendor who can.
Material Composition
The sheet must identify the primary fiber content by percentage. For a Kapetto hand-knotted wool rug, this would read something like "100% New Zealand wool pile on cotton warp and weft." For blended products, each fiber and its percentage must be listed. The construction method (hand-knotted, hand-tufted, flatweave, loom-knotted) should be stated explicitly, along with knot density expressed in KPSI (knots per square inch) for knotted products.
Dimensional Data
Standard dimensions and available custom size ranges should be documented. Include pile height (expressed in millimeters or inches), total thickness including backing, and weight per square foot or square meter. For Kapetto's cashmere loom-knotted collection, pile height is 15mm — a detail that matters for transition strips, door clearances, and ADA threshold compliance.
Performance Characteristics
Architects need quantifiable performance data, not marketing language. The specification sheet should include:
- Colorfastness ratings per AATCC standards (lightfastness, crocking, washing)
- Abrasion resistance per ASTM D4966 (Martindale) or ASTM D3884 (Taber)
- Dimensional stability after cleaning
- Soil resistance and cleanability ratings
- Static propensity per AATCC 134 (relevant for commercial installations near electronics)
Fire Testing and Compliance
This is non-negotiable for commercial, hospitality, and multifamily residential projects. The specification must reference applicable fire test results:
- ASTM E648 (Critical Radiant Flux) — required for commercial corridors and exits
- ASTM E662 (Smoke Density)
- CPSC FF 1-70 / ASTM D2859 (Methenamine Pill Test) — the baseline federal standard for all carpet and rugs sold in the United States
- NFPA 253 (Flooring Radiant Panel Test)
- California TB 117 where applicable
Natural fiber rugs, including wool and jute, inherently perform well in fire testing due to wool's natural flame resistance and high ignition temperature. Kapetto provides fire test documentation upon request for any product specified in a commercial project.
Sustainability Certifications
For projects targeting LEED, WELL, or Living Building Challenge certification, the specification sheet should document relevant third-party certifications. Kapetto holds eight certifications: GoodWeave (child labor free), GOTS (organic textiles), RWS (responsible wool), GRS (global recycled standard), SA8000 (social accountability), SEDEX (ethical trade), ISO 9001 (quality management), and C-TPAT (supply chain security).
GoodWeave certification is particularly relevant for LEED Social Equity credits and WELL Community features. GOTS and RWS certifications support Materials credits in both LEED v4.1 and WELL v2.
Maintenance Protocols
The specification should include manufacturer-recommended maintenance procedures, including daily care (vacuuming frequency and method), periodic professional cleaning protocols, stain treatment guidelines, and any restrictions on cleaning chemicals that could damage the fiber or void warranties.
The Submittal Package
Beyond the specification sheet itself, architects assembling a submittal package for owner or construction manager review will typically need:
- Product data sheets with all technical specifications
- Physical samples — either a swatch or a strike-off for custom work
- Shop drawings showing rug placement, dimensions, and relationship to adjacent finishes
- Certifications and test reports as described above
- Warranty documentation
- Care and maintenance manual
Kapetto provides complete submittal packages for trade account holders. The process begins with a request through the trade portal, and a dedicated account representative assembles the documentation specific to the product and project type.
How to Request Specification Sheets
The process varies by manufacturer, and the ease of obtaining specification documentation is itself a useful filter for evaluating trade partners. Some manufacturers treat spec sheets as an afterthought, producing them only when pressed. Others, including Kapetto, maintain specification documentation as a standard part of the product offering.
To request specification sheets from Kapetto:
- Apply for a trade account if you do not already have one
- Contact your account representative with the product name, project type, and any specific compliance requirements
- Specify whether you need the documentation in CSI three-part format, a condensed product data sheet, or both
- Request physical samples simultaneously to include in the submittal binder
Common Specification Mistakes
Architects new to rug specification often make a few predictable errors worth noting.
Specifying by brand name alone. A proper specification includes "or approved equal" language unless the project is sole-sourced. If you want a specific Kapetto product, write a proprietary specification with justification (unique construction method, specific certification, custom colorway matched to project palette).
Omitting transition details. Where a rug meets hard flooring, the specification should address edge treatment, potential for rug pads or anti-slip underlays, and any transition strip requirements. This is especially critical in ADA-compliant projects where threshold heights are regulated.
Ignoring lead times in the schedule. Custom hand-knotted rugs require 23 to 30 weeks of production time. This must be accounted for in the project schedule, and early specification is essential to avoid delays during the furnishing phase.
Underspecifying for hospitality. Hotel and restaurant projects demand more rigorous performance data than residential work. If the rug will be in a public space, ensure the specification addresses commercial fire testing, not just residential standards.
Why This Level of Documentation Matters
Rigorous specification documentation protects everyone involved in the project. It protects the architect by demonstrating due diligence in material selection. It protects the owner by ensuring the product meets the performance requirements of the space. And it protects the manufacturer by establishing clear expectations for what was ordered and what will be delivered.
For architects accustomed to working with tile, stone, wood, and textile manufacturers who provide comprehensive technical documentation, rugs should be held to the same standard. Kapetto's artisans produce work that meets that standard, and the documentation reflects it.
Request your specification package through the trade program and give your construction documents the same level of completeness for floor coverings that you demand for every other finish in the project.
