Protect and Connect

Protect structural timber and build safely and efficiently with Stora Enso protective solutions and accessories. Multi-functional coatings and membranes increase construction speed on-site, and deliver outstanding results both during and after construction.

Protect

Come rain or shine Stora Enso has you covered!

At Stora Enso, we want to make it as easy as possible for you to build with Sylva™ by Stora Enso, and that includes offering simple and effective coatings and membranes to protect against, moisture, UV damage, and insects. Many of our coatings come in a variety of hues to enhance the overall visual surface and have minimal environmental impact.  

Add another layer of prefabrication to your Sylva™ by Stora Enso products

Coatings and membranes can save thousands of valuable construction hours and resources, reduce the risk of expensive remedial work, and dramatically extend a building’s lifespan. With the rise of low-carbon design, we’re experiencing incredible advances in the development of protection available for mass timber. But how do you know which products are appropriate for your building project? And how do you know the site contractor will apply the necessary coatings and best practices on-site according to the climatic and regional regulations?

The simple solution is to let Stora Enso protect your wood products for you. We offer a comprehensive service to advise you with experienced technicians on the right protective measures. We operate an automated state-of-the-art coating line that applies the highest quality water-based coatings - an investment of over nine million euros that we put towards our customers’ success.

Hydrophobic Coating

The hydrophobic coatings we apply repel water and protect Sylva™, helping maintain a stable moisture content during construction.

Applied in factory-controlled conditions, they prevent water and dirt from entering and at the same time allow moisture to escape. The coating is highly weather resistant and is not affected during lifting and handling.

Benefits

  • No need for additional drying time on site 

  • Reduced risk of water damage 

  • Enables year-round construction 

Key facts

  • Water-dilutable varnish based on acrylate and biocide-free 

  • Temporary moisture protection for approximately 12 weeks 

  • Environmental Product Declaration (EPD) certificate available 

  • Suitable for Sylva CLT Walls and Floors 

  • Compatible with other coatings offered by Stora Enso  

UV Hydrophobic Coatings

Because Sylva is made from solid wood, it naturally contains lignin which is sensitive to UV radiation. While lignin degradation has no structural impact, it can affect the visual appearance over time.

Benefits

  • Reduced risk of moisture and UV damage 

  • Saves valuable construction time 

Key facts

  • Suitable for Sylva CLT Walls and Floors 

  • Satin finish for all colour options 

  • Compatible with other coatings offered by Stora Enso  

  • Biocide-free with low environmental impact 

  • Environmental Product Declaration (EPD) certificate available 

End Grain Sealer

Regardless of the visual surface quality, some end grain is always exposed to the elements and is susceptible to absorbing moisture, and swelling.

But, with the highly weather-resistant sealer we apply, it’s possible to prevent water from getting trapped in the wood during construction. This avoids costly delays waiting for the wood to dry out or expensive remedial work from any mould or rot that might have developed.

Benefits

  • Water-dilutable based on acrylate, allowing the wood to breathe with open diffusion 

  • No costly construction delays while wood dries out

  • Reduced risk of end grain damage 

  • No need for time-consuming on-site application  

  • Ensure tight tolerances 

Key facts

  • Environmental Product Declaration (EPD) certificate available 

  • Effective sealing of the CLT microstructures to reduce water damage 

  • Biocide-free with low environmental impact 

  • Compatible with other coatings offered by Stora Enso  

  • Temporary moisture protection for approximately 12 weeks 

Insecticide Coating

When insects enter an infrastructure, they can cause incredible damage. Stora Enso offers a highly effective bio-based solution with insecticidal and fungicidal properties to tackle this issue.

Benefits

  • High level of protection during transport, site storage and installation as materials arrive pre-treated, securely wrapped and with our just-in-time delivery service. 

  • Effective against wood-eating larvae (house buck, lyctus, rodent beetle), termites, fungi, and basidiomycetes (brown and white rot).  

Key facts

  • Preserves the natural appearance of Sylva 

  • Available as a colourless coating

  • CTB-P+ certified

Temporary Membrane

We offer heavy-duty protection if you anticipate your Sylva CLT Floors being exposed to standing water on the construction site.

The membrane can be applied in our factory or sealed with specialised tape on-site. It works very well because it is breathable, so residual moisture can dry out.

Benefits

  • Reliable moisture protection during transportation, assembly and construction 

  • Translucent so wood structure remains visible 

  • Robust and non-slip

Key facts

  • Available for Sylva CLT Floors 

  • Ideal in combination with our end grain varnish

  • Not suitable for visual grade Sylva elements

Let us do the heavy lifting for you!

Preinstall Sylva™ Walls, Floors, and more with safety lifting equipment

Many contractors install lifting devices on-site using local labour to hoist mass timber building elements into place. With multiple hardware options available and trans-international regional guidelines, this step in the construction process can be time-consuming. Failure to install lifting equipment with the exact weights and balance points before installation can result in damage to products, property and life.

At Stora Enso we offer a comprehensive service to reduce those risks and headaches by preinstalling lifting devices in factory-controlled settings with computer-aided design and precision. Our technical team of experts advise on the best equipment and oversees every detail so you can stay focused on your project and the final inspection checks for a smoother overall construction process with a quick and efficient uptime.

Lifting Devices (reusable and non-reusable)

We offer a range of reusable and non-reusable lifting devices, everything from, anchors, yokes and lightweight to heavy-duty rigging equipment.

Our technical experts have a comprehensive body of knowledge of many leading industry products available and can best advise you on the most appropriate device for your project’s needs.
