Channel Anchor Insulation Pocket for Masonry Veneer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring systems for insulated masonry veneer walls often compromise insulation integrity by piercing or tearing the insulation during installation, especially with thicker insulation requirements, leading to air and moisture infiltration.
Innovation Solution
A channel anchoring system that secures both the veneer and insulation to the framing or backup wall without using invasive fasteners, utilizing a pocket compartment formed by channel anchors to house the insulation without tearing or puncturing it, and includes a wire formative veneer tie for seismic reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional wall anchors with pronged legs are used to secure insulation, then mechanical stability is provided, but insulation integrity is compromised by piercing and tearing
Solution Approach 1:
The invention extracts the harmful fastening function from the insulation itself and relocates it to the masonry veneer. The channel anchor secures to the veneer through embedment in mortar joints, while the insulation is retained by friction and compartmentalization within the channel, eliminating the need to pierce or tear the insulation for attachment.
Solution Approach 2:
The channel anchor acts as an intermediary element between the masonry veneer and the insulation. It provides the mechanical anchoring function to the veneer while creating a protected compartment that holds the insulation without direct fastening to it, thus mediating between structural attachment requirements and insulation integrity requirements.
2Quantity of substance
If thicker insulation is installed to meet energy code requirements, then thermal insulation performance is improved, but the risk of tearing and infiltration increases
Solution Approach 1:
The invention removes the source of infiltration by eliminating the tearing mechanism. The channel anchor system allows thick insulation to be installed without piercing it, as the anchor secures to the veneer and creates a compartment that accommodates the insulation thickness while maintaining the insulation's continuity and seal integrity.
3Strength
If invasive fasteners are used to secure insulation, then attachment strength is improved, but insulation continuity and seal integrity are compromised
Solution Approach 1:
The invention extracts the fastening action from the insulation and applies it to the masonry veneer instead. The channel anchor is embedded in the veneer's mortar joints to provide attachment strength, while the insulation remains continuous and unperforated, maintained only by friction and the compartmentalizing effect of the channel.
Solution Approach 2:
The channel anchor serves as an intermediary that bears the attachment load from the veneer and transfers it to the insulation through friction and compartmentalization, rather than directly fastening to the insulation. This maintains insulation continuity while providing secure attachment.

AI summary
A channel anchoring system for cavity walls is disclosed and includes a channel anchor and veneer tie. The anchoring system is used in conjunction with building structures that have a masonry construction veneer anchored to a steel stud frame or a masonry backup wall. The channel anchoring system secures both the veneer and the insulation to the framing or backup wall. The channel anchor includes a pocket compartment for the insulation that provides a non-invasive means for securing the insulation, thereby maintaining the insulation integrity.
