Whether a building features a traditional storefront or a complex system of curtain walls and paneling, LCL provides full-service engineering for office and retail space, warehouses, arenas, manufacturing, government, and various other specialty structures.

Our engineered products include:

• Curtain Walls

• Storefronts

• Total Vision Glass

• Skylights and Canopies

• Exterior Cladding

We offer engineering services for traditional windows and doors, residential construction projects including skylights and window wall systems, and even commercial products used for residential applications. Our homes are castles, so we consult for new and remedial construction, whether yours is an estate home, townhouse development, or high-rise apartment.

We also provide engineering sign-off for:

• Guardrails and Balustrades

• Glass Fins, Stairs, and Floors

To meet the increasing demand for innovative designs, we specialize in designing and certifying systems that incorporate glass in unique applications.

Our professional engineers also evaluate and model support structures, which is essential for upgrading older buildings to enhance performance and aesthetics.

Being an NFRC certified Simulation Laboratory our team of simulators regularly conducts thermal analyses for all types of windows and doors in all development and construction phases. We work with extruders and manufacturers to rate their windows as part of NFRC or CSA certification, Glazing companies who need to prove the thermal performance of un-certified products, Architects & General Contractors who require a site-specific fenestration thermal performance calculation, as well as property owners & bylaw officers seeking thermal performance verification. Depending on the application, some of the main ratings we provide in our reports are:

• U-value/U-factor (this is how much heat will pass through your window). The lower the number, the better your product keeps heat in.

• Solar heat gain coefficient (how much your window will gain unwanted heat; particularly important during summer cooling seasons). The lower the number, the less money you’ll spend on air conditioning.

• Visible transmittance (how easily you can see through the window). The higher the number, the more natural light that can pass through.

• Condensation resistance (how much condensation collects on your window). The higher the number, the better a product resists condensation.

We are excited to announce the launch of our latest service: Environmental Product Declarations (EPDs), designed specifically for window and door manufacturers in North America.

As sustainability continues to be a growing focus within the construction industry, having a clear, reliable, and verifiable environmental impact profile is essential. Our EPDs are developed in full compliance with North American standards and are crafted with a deep understanding of fenestration products. This expertise allows us to capture the time and energy you have invested in your products, allowing you to:

• Demonstrate environmental responsibility through verified lifecycle data

• Attract environmentally conscious buyers looking for sustainable products

• Ensure compliance with green building certifications like LEED

• Enhance transparency and identify weak points in your product lifecycle

With our expertise, we aim to simplify the process of creating EPDs for fenestration products, providing you with an invaluable tool for displaying the performance of your designs.

Contact us today to learn more about how we can help you achieve sustainability goals and enhance your market position with EPDs.

Our shop drawings provide clients with highly detailed, precise technical drawings that ensure accurate fabrication and construction. With extensive experience, we specialize in creating shop drawings that align with your project specifications, avoiding errors and delays during construction. Our Drafting Services offer organized, precise, and meticulously crafted drawings; using AutoCAD, we enable efficient project execution. We pride ourselves on delivering accurate, high-quality work that supports your project’s success from start to finish.
