Hardwood Grade Can Raise Shutter Price

Hardwood grade measures the percentage of clear, defect-free surface a board yields, not its strength. For shutters, that clear yield decides whether a panel is fit to stain or should be painted, and it shifts the price per square metre significantly. Most homeowners do not need the top grade everywhere; they need the right grade matched to the finish they actually want.

TL;DR:

  • Homeowners should prioritize finish type first, as stain finishes require higher grades like FAS or Selects, while paint finishes can use lower grades such as No.1 or No.2 Common.
  • The price difference between FAS and No.1 Common grades can be significant, mainly because higher grades need less timber wastage, especially for wider or longer louvres.
  • Grain and species choice impact durability and appearance more than grade alone, with species like oak being harder and better suited for high-traffic areas, while basswood or poplar are ideal for painted finishes.
  • Always request a sample in the actual species and grade under your lighting before purchasing, since grade labels are averages and do not guarantee specific board quality.
  • Properly kiln-dried and acclimatized timber, along with a professional survey, ensures the grade and species match your room’s needs and reduce post-installation movement.

What hardwood grade means for shutters: the clear-yield basics

Grading rules for hardwood come from the National Hardwood Lumber Association (NHLA), and they measure appearance, not load-bearing capacity. A board graded FAS is judged on how much of its face is free from knots, stain, and other defects, not on how well it would hold a shelf. That distinction catches a lot of homeowners out, because “top grade” sounds like it means “strongest” when it actually means “cleanest”.

The AHEC/NHLA grading guide sets out four grades relevant to shutter makers, each defined by clear-cutting yield:

  • FAS requires roughly 83⅓% clear yield and targets high-end millwork, the kind of stock used for visible, stained joinery.
  • FAS-1F/Selects allow one poor face while the other meets FAS standards, useful when only one side of a component will show.
  • No.1 Common yields less clear surface per board and works well where boards get re-sawn into smaller parts.
  • No.2 Common carries more visible character and defect, and it belongs almost exclusively in painted work.

Grading exists because millwork buyers need a shared shorthand. Without it, a manufacturer would have to inspect every board by eye and negotiate price from scratch, which slows production and raises cost for everyone downstream, including you.

Which grades shutter makers actually use

Shutter manufacturers rarely buy one grade for an entire order. They match grade to what the finished component will look like, and that decision runs through every quote you receive.

  1. Stain-grade panels demand FAS or Selects. When grain and colour will show under a clear or tinted finish, manufacturers need long clear runnings, so they buy the higher grades and accept the higher raw material cost that comes with them.
  2. Paint-grade louvres tolerate No.1 or No.2 Common. Paint hides mineral streaks, small knots, and colour variation, so manufacturers can specify a lower grade, or re-engineer boards into laminated blanks that give consistent, paintable louvres at a lower cost than top-grade solid stock.
  3. Louvre width and length dictate the ceiling. Wide, long louvres need bigger clear areas to cut from, which pushes production toward higher grades regardless of finish. Narrow slat shutters have more flexibility because shorter clear runs are easier to find in lower grades.

The price gap between a full FAS specification and a No.1 Common paint-grade order can be substantial, driven almost entirely by how much usable clear timber a mill has to discard to hit the higher standard.

Paint or stain: how grade decides your finish options

Your finish choice should come before your grade choice, not after. Trying to reverse that order, picking a grade first and hoping the finish works out, is how homeowners end up disappointed by blotchy stain or a paint job that still shows every knot underneath.

  • Stain finishes are honest about the wood beneath them. A clear or lightly tinted stain lets every grain line, colour variation, and mineral streak show through, so it only looks right on FAS or Selects stock.
  • Paint is forgiving of small imperfections. A painted shutter can use lower-grade stock because filler and primer handle minor knots and colour shifts before the topcoat goes on.
  • Mixed grain within one room reads as a mistake in stain, not in paint. If you want a stained hardwood look, ask for boards from the same batch and grade to avoid visible colour jumps between panels.
  • Sample panels settle the argument faster than grade names do. A grade label tells you what to expect statistically across a batch. It does not guarantee the exact piece in front of you, so always ask to see a finished sample under your own lighting before committing.

Species and hardness: the factor grade alone won’t tell you

Grade tells you how clean a board is. Species and hardness tell you how it will behave once it’s cut, finished, and living in your window for the next decade, and the two considerations pull in different directions more often than people expect.

Pro Tip: Ask for the species and the Janka hardness rating together, never just one. A high grade in a soft species still dents easily; a hard species in a low grade still shows every flaw once painted.

Basswood and poplar are the standard paint-grade species: light, stable, and cheap to work, but they take stain poorly and mark relatively easily under knocks. Basswood sits at roughly 410 on the Janka hardness scale, a rough measure of how much force it takes to dent the wood.

Oak, by contrast, sits closer to 1,290 on that same scale, roughly three times harder, which is why it’s the default choice for stained hardwood shutters in busy rooms like kitchens and hallways. Paulownia splits the difference: notably light and dimensionally stable, which makes it a favourite where you want a hardwood stain look without the weight or cost of oak.

How to choose the right hardwood grade for your shutters

Work through finish first, then let that decision drive everything else, including which questions you put to a supplier.

  1. Settle paint or stain before you get a quote. This single decision determines the realistic grade range and removes most of the guesswork from comparing prices between suppliers.
  2. Set your budget ceiling second. Once finish is fixed, budget tells you whether you’re shopping within FAS, Selects, or Common grades, and stops you being upsold to a grade you don’t need.
  3. Ask for the exact grade name, not a vague description. “Premium hardwood” means nothing on its own; “FAS” or “No.1 Common” tells you precisely what clear yield you’re paying for.
  4. Ask for the species and a sample louvre in that species and grade. A physical sample under your own window light settles more doubts than any spec sheet.
  5. Ask about kiln-drying and acclimatisation. Properly kiln-dried timber, acclimatised on site before fitting, moves far less after installation than stock fitted straight from the factory.
  6. Ask about lead time and waste allowance. Higher grades and wider louvres often mean longer waits, since mills need more raw stock to hit the same clear yield.
  7. Ask what the guarantee actually covers. A grade name is worthless reassurance if the warranty doesn’t cover warping, splitting, or finish failure.

Pro Tip: If a supplier can’t name the grade, species, and Janka figure without checking, treat that as a red flag rather than a formality. Precise answers on the first ask usually signal a supplier who actually controls their supply chain.

How Shutter World applies grade and species in practice

Ken has spent more than 25 years in the shutter trade, and the lesson that has stuck hardest is simple: the grade on paper only matters once it’s matched correctly to the room, the finish, and the species.

Shutter World’s process reflects that:

  • Every hardwood order starts with a sample approval stage, so you see and feel the actual grade and species before manufacturing begins.
  • Timber is kiln-dried to specification and given time to acclimatise before final fitting, cutting the risk of post-installation movement.
  • Louvre sizing and finish are agreed together, not separately, so the grade chosen genuinely fits what the panel needs to do.
  • Installation tolerances are built in at the survey stage, so a hardwood panel that has settled slightly after acclimatisation still closes and aligns properly.

The grade obsession homeowners don’t need

Most of the advice online treats hardwood grade as the single number that determines quality, and that’s the part worth pushing back on. Grade only tells you how clean a board’s face is. It says nothing about how the finished shutter will wear in your home, how the species handles humidity in a bathroom, or whether a supplier’s kiln-drying process is actually up to standard.

The grade obsession homeowners don't need — overview diagram

The homeowners who end up disappointed are rarely the ones who chose a “lower” grade. They’re the ones who picked a grade without first deciding paint or stain, then discovered the wood couldn’t do what they’d pictured. A No.1 Common paint-grade basswood shutter, correctly specified and well fitted, will outperform a badly matched FAS stain-grade panel in the wrong species every time.

If there’s one thing worth prioritising above the grade name itself, it’s the sample. See the actual board, in the actual species, under your actual window light, before you sign anything. Grade names describe an average across a batch. Your window only cares about the piece it gets.

FAQ

Are shutters outdated in 2026?

No. Demand for made-to-measure hardwood and composite shutters remains strong because they offer light control, insulation, and durability that curtains and blinds don’t match. Grade and species choices, covered above, are what keep them looking current rather than dated.

Are hardwood shutters better than MDF?

Hardwood offers a natural grain and stain option that MDF cannot replicate, plus generally higher dent resistance depending on species. MDF with a polypropylene coating, such as Shutter World’s Seattle range, holds up well in humid rooms and costs less, so the better choice depends on finish preference and room conditions rather than one material being universally superior.

What is the most durable material for window shutters?

Durability depends on the exact use case: harder hardwood species like oak resist dents better, while coated MDF resists moisture and warping better in bathrooms and kitchens. Species and Janka hardness matter more than grade alone when comparing long-term wear.

What are the best brands of wooden shutters?

The right brand depends on whether you want off-the-shelf sizing or a bespoke fit for irregular windows. Shutter World specialises in made-to-measure hardwood shutters, including bay, arched, and skylight shapes, with a professional survey and installation service included.

Does a higher hardwood grade always cost more?

Generally yes, because higher grades like FAS require more clear, defect-free timber per board, which increases waste during milling. For painted shutters, a lower grade often delivers the same visual result at a lower price, so paying for FAS only makes sense when you’re planning a stained finish.
