Lifetime Sash is the less expensive, more durable alternative to wood window preservation. It’s gaining more and more traction among smart historic building owners, contractors and business owners who believe in cost-effective, gorgeous replicas that last a lifetime.

In fact, our clients insist we use it. It simply doesn’t make sense to use any other wood product to replicate their windows. Lifetime Sash lasts… well, a lifetime. We guarantee it!

We’ve gathered the most frequently asked questions from our clients and partners.

1. Is the wood used to make Lifetime Sash like natural wood?

Yes. Lifetime Sash is like natural wood.

2. Can I use Lifetime Sash in extreme situations, like my beach house windows?

Yes. In fact, Lifetime Sash’s durability against rot makes it ideal for windows and all exterior applications subject to the elements. Fungi doesn’t recognize it. Insects can’t eat it. It won’t swell or rot. Lifetime Sash is ideal for every window application.

3. Is Lifetime Sash similar to old-growth lumber?

Yes – but better. Durable woods like old-growth species are typically slower growing. Our Lifetime Sash wood is made using fast growing, sustainably forested radiata pine. Therefore, old growth forests are not threatened or depleted to create Lifetime Sash. This is good news because it means our Lifetime Sash can keep up with the demands and volume of our country’s aging historic windows.

4. What’s acetylated wood? How is Lifetime Sash (LTS) made?

Lifetime Sash is treated wood. The treatment? Acetylation. It’s a process that transforms what’s already in the wood’s chemical makeup into something more ideal.

Wood contains chemical groups called hydroxyls. As you can guess from the name, this is the chemical responsible for wood’s water absorption and release. It’s why wood swells and shrinks, depending on the conditions the wood is in. Enzymes that eat wood also originate in hydroxyl sites.

Eaten wood? That’s rotted wood.

In acetylation, the wood is kiln-dried, soaked in acetic acid (yep, like in vinegar) and kiln-dried again. The hydroxyls are transformed into acetyls: hydrogen, oxygen and carbon, already present in all wood. They make the wood indigestible to those enzymes that cause decay, and it greatly reduces water absorption properties.

These acetyl groups therefore transform wood into a dimensionally stable, more durable form. And because they were already in the wood, only coaxed out by the treatment, acetylation is natural. It’s the result of 75 years of scientific research to make wood less prone to decay.

And remember, LTS has been made indigestible. It won’t rot, and won’t be eaten!

Pests that try to eat it will only starve to death. Fungi don’t recognize LTS as wood at all.

5. Does that mean Lifetime Sash is stronger wood?

Acetylation doesn’t change the wood, essentially. So, for example, you can’t expect the ‘strength’ of hickory on an aspen wood.

But unlike other processing that makes wood brittle, acetylation does increase wood hardness by 10%. No other wood window can match our Lifetime Sash. LTS is going to be a more durable replica that lasts a lifetime – every time.

6. Does it change the color of the wood?

Nope. We are able to paint Lifetime Sash like any other wood to match your existing windows.

7. Is Lifetime Sash treated on the surface only?

No. LTS is acetylated all the way through. When you cut LTS, you’ll see no unacetylated sections. No further treatments or preservatives are necessary.

8. What’s the difference in Lifetime Sash to other treated, modified wood?

Unlike other wood treatments that make wood inhabitable to bacteria, fungi and rot, LTS is non-toxic. Meanwhile, the non-toxic thermal modifications meant to break down wood’s edibility, to prevent decay, also weakens the wood. Wood Window Makeover’s Lifetime Sash is not weakened in any way.

You can rely on the durability of Lifetime Sash. Guaranteed.

Yes, guaranteed.

Through sophisticated analysis techniques for acetyl content measurements, we ensure every single Lifetime Sash is of consistent quality.

9. Are Lifetime Sash paintable?

Yes. You’ve seen our wood window makeover projects on the website. Those are Lifetime Sash, painted a variety of glorious colors! And because LTS doesn’t shrink or swell, coat adhesion is so much better than on any other wood, and get this… maintenance is three to five times the normal lifecycle!

10.How do you create a Lifetime Sash replica of my window?

We custom make each sash in our state of the art facilities in Tampa, Florida where we use modern equipment to replicate exact duplicates of their historic counterparts.  We have two standard profiles, ogee and ovolo, that we use on 90% of our lifetime sash. Custom profiles are available for your unique sash.

11. Do you treat existing windows? That is, remove them, turn them into Lifetime Sash, and reinstall them?

Yes.  We call this a “hybrid” restoration because it combines the best of every possibility.  Historic homes keep their historic style windows, wavy glass, ropes and pulleys. Our restorations are guaranteed for life.

We think you’ll agree that Lifetime Sash are pretty impressive.
