Roof & Soffit Protection
Evaluate ArkiShield within project-specific roof cover-board, soffit, and eave details.
Fire-conscious construction
Fire-Resistant Building Solutions
Wildfire, urban fire, and structure-to-structure exposure are changing how we think about building materials. Arkitor provides mineral-based systems that can help reduce combustible materials in selected locations—from the roof and exterior envelope to interior walls, floors, and decorative finishes.
The Building Envelope Is Part of the Defence
WHOLE-BUILDING APPROACH
Where Mineral-Based Systems Can Fit
Start with the part of the building you need to solve, then confirm the current product and assembly information with Arkitor.
Explore ArkiShield
Exterior Wall Protection
Consider mineral-based panels within evaluated sheathing and building-envelope applications.
Interior Walls & Ceilings
Use ArkiCore as a starting point for partitions, wall linings, ceilings, and prefabricated interiors.
Floors & Subfloors
Evaluate ArkiFloor within approved residential, commercial, modular, and prefabricated floor assemblies.
Architectural Finishes
Coordinate ArkiDecor mineral finishes with the performance and design requirements of the interior system.
When Wildfire Reaches Home
LYTTON, BRITISH COLUMBIA · 2021
A Community Changed in Minutes
On June 29, 2021, Lytton recorded 49.6°C, Canada’s highest officially recorded temperature. The following day, wildfire swept through the community, destroying approximately 90% of Village buildings and claiming two lives.
The event reinforces the need to consider the complete Home Ignition Zone and the building itself: roofs, soffits and eaves, vents, exterior walls, decks, attachments, interior assemblies, and surrounding combustible materials.

WEST KELOWNA, BRITISH COLUMBIA · 2023
The Fire Did Not Need to Touch the House
A post-fire investigation of the Grouse Complex fires found that neighbourhood ignition occurred almost exclusively through wind-driven embers rather than direct contact from the main flame front. Embers travelled more than 2.5 kilometres across Okanagan Lake, and combustible materials close to structures strongly influenced outcomes.
The study also found that failed combustible soffits allowed fire to enter a number of homes and spread into attic spaces—making the roof-to-wall transition a critical design consideration.

A House Can Ignite from the Outside In
THE ARKITOR WHOLE-BUILDING APPROACH
Protect the Building From Exterior to Interior
Arkitor's opportunity is not one individual board. It is the ability to coordinate mineral-based materials across multiple vulnerable areas while confirming the current product information and complete assembly requirements for the project.

MATERIALS AND ASSEMBLIES
A Board Is One Part of the Fire Strategy
Terms such as fire-resistant, non-combustible, flame-spread classification, and fire-resistance rating describe different properties. A required hourly rating must be tied to the complete tested construction—not assumed from one panel alone.
PROJECT-SPECIFIC SELECTION
Confirm the Right Product Before Specification
Application, framing, fasteners, joints, finishes, penetrations, exposure, and local requirements can all affect the appropriate solution. Contact Arkitor for current approved information relevant to your project.
