Hardwood vs Softwood Windows: Which Is Right for Your Home?

Timber windows bring warmth and authenticity that uPVC simply cannot match — but should you choose hardwood or softwood? Both make excellent bespoke windows; the right choice depends on your property, budget and how much maintenance you want to take on.

Softwood windows

Softwood (typically slow-grown redwood or Accoya®) is the traditional choice for painted joinery. It is easier to work, takes paint beautifully, and is more affordable.

• Lower cost than hardwood
• Excellent for painted finishes — period-correct on many homes
• Needs repainting every 5–8 years to stay protected
• Modern engineered softwood and Accoya® offer outstanding stability and 50-year-plus lifespans

Hardwood windows

Hardwoods such as oak and sapele are denser, more durable and naturally beautiful when stained or oiled rather than painted.

• Exceptional durability and resistance to wear
• Stunning grain — ideal for a natural oiled or stained finish
• Higher cost, but a longer life with less frequent maintenance
• A natural fit for oak-framed and high-end properties

Cost comparison

As a rule of thumb, hardwood windows cost roughly 15–30% more than the equivalent softwood units. However, the lower maintenance and longer lifespan of hardwood can close that gap over 20–30 years.

Which should you choose?

Choose softwood if you want a painted finish, a period-accurate look, or a lower upfront cost. Choose hardwood if you want a natural timber finish, maximum longevity, or are matching an oak-framed home. Either way, a well-made timber window will comfortably outlast a plastic one and can be repaired rather than replaced.

We handcraft both storm-proof and traditional flush-casement windows to suit any property. See the windows page, or read about period window restoration if you own a listed or older home.

Hardwood vs Softwood Windows: What's the Real Difference for Your Home?

The terms are botanical, not a measure of strength. Hardwoods come from broadleaved, usually deciduous trees such as oak and sapele. Softwoods come from conifers such as pine, spruce and larch. That is the whole distinction, which is why a few softwoods are tougher than some hardwoods, and why balsa, one of the lightest timbers going, is technically a hardwood. Judge a window by the species and the quality of the stock, not by the label.

On heat, timber of either type insulates far better than aluminium or steel, and softwood is marginally better than dense hardwood because air pockets in lighter timber slow heat loss. In practice the glazing unit, the draught seals and the fit of the sash make a far bigger difference to your U-value than the choice of frame timber.

For exposed hillside plots, coastal properties or any elevation that takes the weather, we usually steer people towards a durable hardwood or a modified timber such as Accoya®, paired with a good paint or oil system and a sensible maintenance routine. Salt air and driving rain punish a thin finish more than they punish the wood itself.

We can specify timber from certified, responsibly managed forests for any window we make, so just ask when you enquire.

Common questions

What's the actual difference between hardwood and softwood trees, not just the windows?

Hardwood trees are broadleaved and typically lose their leaves in winter, while softwoods are conifers with needles and cones. Hardwoods generally grow more slowly, which tends to give a denser, tighter grain. It is a classification of the tree, not a guarantee of how hard or strong the finished timber will be.

Which is better for a house near the coast, hardwood or softwood windows?

In salty, wind driven conditions we would normally recommend a durable hardwood such as oak or sapele, or a modified softwood like Accoya® that is designed to resist moisture movement. Whichever you choose, the finish does the real work, so expect to check and refresh the paint or oil more often than you would inland.

Do hardwood windows keep the heat in better than softwood ones?

Not really. Lighter softwoods insulate very slightly better than dense hardwoods because of the air held in the timber, but the difference is small. Your double glazed unit, the seals and how accurately the sash is fitted will decide how warm the window feels.
