54″ Wide WoolSafe Schedule 3 Crib 5 Interliner Barrier Felt

WoolSafe Schedule 3 Crib 5 Upholstery Barrier Felt, 54" Wide

WoolSafe Schedule 3 Crib 5 Upholstery Barrier Felt is a specialist fire-retardant interliner used between upholstery fillings and outer covering fabrics in suitably specified furniture constructions.

Its primary purpose is to provide a barrier layer where the chosen decorative covering does not independently meet the required fire-performance standard and the furniture design permits an appropriate interliner.

The felt-style construction makes WoolSafe suitable for consideration on upholstered seats, backs, arms and shaped furniture components where a conventional woven barrier cloth may be less convenient to fit.

Supplied in a 54" width (approximately 137cm), it is available by the linear metre or in 30-metre rolls.

see Calico, Interliner & Cambric range for related fire-barrier and upholstery lining products.

Where Is WoolSafe Barrier Felt Used?

A specialist upholstery fire interliner may be incorporated into furniture where a barrier layer forms part of the approved upholstery construction.

Potential applications include:

• Sofas and armchairs: Providing a specified barrier between fillings and the decorative cover.
• Upholstered headboards: Covering suitable padded sections where the construction requires a fire barrier.
• Dining and occasional chairs: Incorporating a barrier into appropriately tested upholstery assemblies.
• Furniture restoration: Replacing or introducing an interliner where the applicable construction and regulations permit it.
• Contract furniture: Use in hospitality, commercial and other settings where the specified assembly and test evidence support the application.

The suitability of WoolSafe must be checked against the intended furniture use and the full materials specification. Contract furniture may be subject to requirements different from those applying to domestic furniture.

Understanding Schedule 3 and Crib 5

describes this product as a Schedule 3 Crib 5 interliner barrier felt.

These terms relate to fire-performance testing and barrier applications, but they should not be taken as a blanket declaration that any upholstery fabric can be used safely or legally simply by adding the interliner.

The complete upholstery construction matters, including the covering, foam, other fillings, barrier continuity, seams and manufacturing method.

Where a fire barrier is needed, confirm the supplier's current test documentation, the applicable regulatory requirements and whether the proposed combination of materials is acceptable.

This is particularly important for contract furniture and projects requiring documentary evidence of compliance.

Fitting WoolSafe Upholstery Interliner

WoolSafe is installed between the upholstery filling and the outer cover as part of a suitable furniture construction.

Before cutting, measure the full upholstery area, including curved sections, seam allowances, fixing areas and any changes in surface direction.

The 54" width may allow some furniture panels to be covered without joins, reducing potential gaps in the intended barrier layer.

When preparing the material, take care not to create unnecessary tears or openings. Any joins, stitching, fixing methods and covered areas should follow the relevant upholstery specification.

For preparation, browse Upholstery Shears & Snips and Measuring & Marking Tools.

The interliner should remain correctly positioned when the outer cover is fitted. Do not assume that ordinary adhesives or alternative fixing methods are acceptable unless permitted by the documented construction.

WoolSafe Felt or Cotton Crib 5 Barrier Cloth?

offers two specialist barrier materials within this range.

The 60" Wide 100% Cotton Schedule 3 Crib 5 Interliner Barrier Cloth provides a woven cotton alternative, available by the metre or in 80-metre rolls.

WoolSafe offers a felt-style construction in a 54" width, with 30-metre rolls available.

The choice depends on how the material needs to fit around the furniture, the required covering width and, most importantly, the test evidence supporting the intended upholstery assembly.

Conventional Natural Calico Lining Cloth serves a different purpose. It can provide a lining over fillings but should not automatically be substituted for a specialist Schedule 3 barrier.

For feather-filled cushion interiors, 60" Waxed Cambric is another specialist fabric with a different function.

Ordering WoolSafe Barrier Felt

Before ordering, confirm the material specification, required quantity, project fire-performance requirements and compatibility with the complete furniture construction.

WoolSafe Schedule 3 Crib 5 Upholstery Barrier Felt is a specialist fire-retardant interliner designed to provide a protective layer between upholstery fillings and outer covering fabric.

Used in suitable furniture constructions where the decorative fabric does not independently meet the required fire-performance standard, this felt-style interliner provides an additional barrier beneath the finished upholstery.

Product specifications:

• Product: WoolSafe Schedule 3 Crib 5 Interliner.
• Width: 54" (approximately 137cm).
• Material type: Fire-retardant barrier felt.
• Supply options: Per linear metre or 30-metre roll.
• Applications: Upholstered sofas, chairs, headboards, furniture panels and suitable contract upholstery.
• Purpose: Providing a fire-retardant barrier between fillings and covering fabric.

The felt-style construction can be shaped around suitable upholstered panels, arms and padded furniture sections.

For a woven alternative, consider the 60" Cotton Schedule 3 Crib 5 Barrier Cloth.

The correct barrier must be selected according to the intended furniture use, applicable requirements and relevant test documentation. An interliner alone does not guarantee compliance of the finished item.
