Quad Lock Building systems has been in business since 1994. At the time of their launch, Quad Lock was a pioneer in flat-wall insulating concrete form (ICF) systems.
Today, Quad Lock remains a leader in ICFs, and their systems can be used to construct a variety of structures.
Quad Lock Concrete Building Solutions
Unlike other ICFs, Quad Lock’s solution is highly versatile and offers a true R-value of up to R-59.
Quad Lock also offers a complete wall form solution and not just the foam. The system provides exceptional support, is less expensive to ship and is ISO 9001 and 14001 certified.
ICF Walls
Quad Lock offers 3” ICF walls with an R-28 value. High Density Polyethylene and Expanded Polystyrene create the ideal formwork for the concrete along with reinforcing steel.
Quad Lock’s ICF walls offer 2–4-hour fire resistance ratings, high durability and low maintenance. In addition, the system provides plenty of space for running utilities and additional insulation layers.
A variety of wall and insulation options are available for wall components.
EPS Panels
- Thickness: 2-1/4,” 3,” 3-1/8,” 4-1/4″
- True R-values: 22, 28, 38, 43, 53, 59
HDPE Ties
- Lengths: 18,” 16,” 14,” 12,” 10,” 8”
Brackets
- Corner
- Straight
- Angle
- Endcap
Brackets eliminate the need for corner bracing and allow for insulation without the need for extra bracing.
Additionally, wire top ties and metal tracks are available to complete the wall assembly.
Corner Brackets
The corner brackets from Quad Lock allow you to create 90-degree corners quickly and easily without any additional bracing.
Made with galvanized steel, corner brackets fit over Quad Lock’s panels and are fitted at 90-degrees to each other.
There are two bracket options to choose from:
Inside Corners
Inside corner brackets are used on each row of inside panels (except for the top row), on the interior corners of T-walls and to create 90-degree corners.
Outside Corners
Outside corner brackets are also used on each row of outside corner panels (except for the top row), but they can also be used to reinforce T-walls.
Angle Brackets
With Quad Lock’s hinged angle brackets, wall angles can be braced and formed at virtually any angle. As a result, brackets are only needed along the outside of the angle, and there’s no need for additional bracing.
Straight Brackets
The straight bracket can be used to secure a 4-way intersection. Simply place two 34” straight brackets across intersecting walls to create a solid connection.
Straight brackets can help provide support for heavy roof components or the reinforcement of large retaining walls.
Endcap Brackets
An endcap bracket helps create insulated endcaps using foam pieces. These brackets are meant to replace plywood or lumber forms. They do not leave any exposed concrete.
ICF Floors & Roofs
Quad Lock’s ICF roof systems and flooring systems are ideal for both commercial and residential use. Known as Quad-Deck, the company’s ICF floor and roof systems offer energy efficiency, strength, quick construction and comfort.
The expanded polystyrene panels feature two steel beams that are molded into the product for support and reinforcement. Quad-Deck is self-supporting.
Compared to a traditional slab, Quad-Deck:
- Uses 33% less steel
- 50% less concrete
By using less steel and concrete, you also reduce your mass and shoring by 50%.
ICF Safe Room Construction
Quad Lock systems can be used to create safe rooms that provide shelter and safety in the event of a natural disaster.
A safe room that meets FEMA’s guidelines would protect against wind gusts up to 250mph and debris.
Quad Lock wall systems and Quad-Deck roofing can be used to create a safe room that meets FEMA’s guidelines. Here’s what their safe room can provide:
- Protection against winds up to 250mph
- Walls with a high fire rating of 3 hours
- Reinforced concrete that protects against extreme wind and flying debris with minimal or no structural damage
The safe room must be properly designed and installed to realize these benefits.
Quad Lock’s safe rooms can be added to a new home construction, or they can be retrofitted into an existing home.
The Benefits of Quad Lock ICF
Quad Lock’s ICF systems provide many advantages over other ICFs, including:
Exceptional Durability
Quad Lock buildings are exceptionally durable compared to buildings with wood frames. Reinforced concrete walls provide up to 8.5 times more strength than wood-framed structures.
When properly designed, Quad Lock walls are highly resistant to tornadoes, earthquakes and hurricanes. They also provide 2-4-hour fire resistance ratings.
Made from Safe Materials
Quad Lock’s panels are made with non-toxic, safe and fire-retardant expanded polystyrene, or EPS. As a result, panels are free from HCFCs, CFCs, polyisocyanurates and other potentially harmful chemicals. As a result, there’s no need to worry about off-gassing or the panels breaking down over time.
Better Indoor Air Quality and Comfort
Quad Lock structures offer an R-value of up to 59, which helps provide a more consistent and comfortable indoor temperature.
Low air infiltration ensures fewer allergens and improves indoor air quality.
The materials used to create Quad Lock structures do not contribute to mold or mildew growth either. They’re not a food source for insects, so there’s no need to worry about pests or mold. Eliminating both of these further improves indoor air quality.
Quad Lock Green Roof Study
To demonstrate the benefits and effectiveness of Quad Lock’s ICF systems, the company partnered with the British Columbia Institute of Technology as part of a green roofs study. The 2-year study looked at the effectiveness of green roof structures.
The company’s test structure featured:
- R-10 insulated slab foundation
- R-22 Quad-Lock walls with 6” concrete
- R-22 Quad-Deck system for the roof structure
- A green roof layer
The study looked at several things, including:
- The roof’s thermal performance and cost savings
- Stormwater quality and quantity
- Carbon emissions savings
- Plant growth performance and maintenance
Data showed that, compared to a control roof structure, Quad Lock’s green roof:
- Reduced heat loss by 50-75%
- Reduced heat gain by 99% throughout all seasons
- Retained about 69% of rain, and 31% of that rain could potentially be reused or disposed of through a municipal system
The data also showed that interior temperatures were nearly constant throughout the study. These findings support claims that Quad Lock structures are more comfortable and energy efficient.
Green roofs, like the one in this study, reduce stormwater runoff, lower energy costs and even reduce noise. They also help demonstrate the effectiveness of ICF forms when used in roof structures or entire building constructions.
Quad Lock systems offer a variety of benefits, are exceptionally durable and highly versatile. Energy savings, greater indoor comfort and better air quality are just a few of the many reasons why Quad Lock remains a leader in the industry.
