What can Qora be installed over?
Qora Cladding and accessories should be installed over structurally rated sheathing with an appropriate water-resistive barrier. Qora can also be installed over dimensional lumber or metal framing when used as in an underpinning or skirting application.
Can Qora be installed over existing siding?
The Qora Cladding Collection can be installed over existing siding panels as long as they are structurally rated and have a weather-resistive coating or overlay. Examples would be Duratemp® Siding, Metal Panel Siding, T-111 Plywood, Huber’s Zip System®, GP ForceField®, LP WeatherLogic®, or LP SmartSide®.
Qora siding panels and accessories cannot be installed over existing lap siding or lap siding covered with fanfold insulation.
Can Qora be installed over Concrete Masonry Units?
Qora siding panels and accessories can be installed over CMU foundations. Low profile Masonry (Tapcon) screws should be used to ensure proper adhesion and fit of Qora fastener veneer covers.
Can Qora be repaired/touched up once installed?
There are several options for repairs and/or touch up of Qora once installed:


  • For filling in excessive gaps, use a high-quality, exterior-grade caulk to fill in the gaps and finish with a brush or sponge to mimic the texture of the mortar. Color-coordinated caulk can be found at most local paint stores and color-matched caulk is available from Arcitell if needed.

  • In the case of cosmetic repairs, use high-quality, exterior-grade paint to touch up scuffed areas. On www.qoracladding.com/documentation is information on the PPG colors used in the manufacturing process and the corresponding Sherwin Williams codes for matching colors. Additionally, touch up kits of PPG paint are available from Arcitell if needed.

  • In the case of significant damage, replace the panel or fill in the damaged area with a high-grade epoxy to recreate the panel surface, then use a high-grade exterior paint to finish the repair area to match the color pattern.
How does Qora perform in freeze/thaw climates?
The Qora Cladding Collection is approved for use in all climates. Arcitell has rigorously tested Qora siding panels and accessories by completing multiple cycles of complete water submersion and -20°F deep freeze with no adverse impacts on the material.
What is Qora’s warranty?
The Qora Cladding Collection and accessories is covered by a 20-year warranty for excessive and uneven fade on the finish and substrate degradation (excessive cracking, chipping, buckling, peeling, separation). Please click here to see complete warranty details. 
Since Qora is new, how can I address questions/concerns about a new technology from a new company?
While The Qora Cladding Collection is a new product line, the core technology, and companies behind it are not.

  • Phenolic resin has been a common ingredient in exterior building materials since the 1970s, with many advancements in durability, performance, and safety.
  • Arcitell sources materials from large trusted, and reliable companies such as Bakelite Synthetics (resin), Owens Corning (fiberglass), and PPG (paint) who have been integral to the development and testing of Qora Cladding.
  • Qora’s technology is manufactured under the license of Acell Industries Ltd who has successfully manufactured and installed similar claddings throughout Europe for 20 years.
  • Arcitell’s parent company, Belden Brick Company, has been a market leader in masonry manufacturing for over 135 years with an emphasis on quality and workmanship. This tradition and adherence to quality standards are foundational to Arcitell’s key operating principles.
