Continuous Insulation (CI) vs. Non-CI Assemblies
Continuous Insulation (CI) vs. Non-CI Assemblies
When designing rainscreen systems for Type V wood frame construction, understanding the difference between continuous insulation (CI) and non-CI assemblies is essential for meeting energy code requirements and performance goals.
Continuous Insulation (CI)
CI systems incorporate a continuous layer of insulation—typically rigid foam, rigid mineral wool, or structurally insulated sheathing - installed on the exterior of the stud wall uninterrupted by framing members. EQUITONE panels are then mounted on vertical wood battens or furring strips, which sits outboard, or on the face of the insulation, maintaining a ventilated cavity between the cladding and insulation.
-
Improves thermal performance and energy efficiency
-
Reduces thermal bridging through studs
-
Supports compliance with IECC and local energy codes
-
Requires detailing for drainage, ventilation, and secure fastening through insulation
Non-CI Assemblies
There are two types of non-CI systems. Either insulation is placed outboard of the exterior sheathing, between the wood battens or furring strips that EQUITONE is mounted to, or there is no exterior insulation used and all the insulation is between the structural studs behind the sheathing.
-
Simpler detailing and lower material costs
-
Suitable for moderate climates or where CI is not required by code
-
Compatible with standard sheathing and fastening methods
-
Maintains effective ventilation behind the cladding
Fasteners
Fasteners
EQUITONE panels can be face-fixed to wood framing using stainless steel screws designed for long-term performance, visual consistency, and ease of installation in residential and light commercial projects.
UNI- Wood Screw DP (Drill Point)
The UNI-Wood Screw DP features a drill point tip that eliminates the need for predrilling, providing faster and more consistent installation on timber frames.
-
Self-drilling to help prevent wood splitting and and also allows for installation through light gauge flashings.
- Color-matched, two-layer coated head for a seamless appearance.
- 304 [A2] Stainless steel with optional marine-grade protective coating for long-term durability.
- Designed for use in vertical facades, soffits, and ceilings.
Design tips
To ensure a durable and visually clean installation on Type V construction, follow these best practices when face fixing EQUITONE panels with UNI-Screw DP fasteners.
Use Oversized Holes to Accommodate Movement
Drill 7 mm diameter holes in the panel to allow for thermal expansion and contraction. This helps prevent stress cracks or panel distortion over time.
Use of EPDM
EPDM placed between the panel and wood elements protects the back of the panel and prevents staining from occurring due to chemicals within the wood leaching into our materials.
Choose the Right Screw Type for the Job
Use UNI-Screw DP (Drill Point) for faster installation with no predrilling required on most timber substrates.
Protect Finished Surfaces with Sleeves
When installing EQUITONE [natura] PRO or [pictura], always insert a stainless-steel screw sleeve into the panel hole before fastening. This prevents damage to the PU topcoat during installation.
Maintain a Ventilated Cavity
Install furring strips or battens to create a consistent ventilation gap behind the panels. This promotes air circulation and supports rainscreen performance.
Align Fasteners for a Clean Finish
Plan panel layout and screw placement to ensure visible fasteners align uniformly across the façade. Use color-matched screw heads for a refined, integrated look.
