Premium Fiberglass Windows and Doors for Serious Dealers

A dealer partnership built on premium fiberglass products, technical credibility, responsive manufacturer support, and support throughout the sales process.

Become an Inline Fiberglass Dealer

Inline Fiberglass manufactures premium fiberglass windows, entrance doors, sliding patio doors, and high-performance product options for residential, commercial, and architectural projects.

Inline is accepting dealer inquiries from qualified window and door dealers, building product distributors, and showroom-based partners interested in carrying Inline products. Dealer opportunities are not exclusive at this time, and Inline does not currently sell in Quebec.

A Product Line Built Around Long-Term Performance

Inline is not a general window company that happens to offer fiberglass. Fiberglass is the material Inline is built around.

That focus gives dealers a clear product story: strong, durable, energy-efficient fiberglass windows and doors designed for customers who care about comfort, design, and long-term value.

For dealers and distributors, Inline can support a premium product offering across several buyer types:

A Complete Fiberglass Product Portfolio

Provide customers with premium fiberglass windows and doors backed by manufacturing expertise, technical documentation, and design flexibility.

Fiberglass Windows for Homes

Inline offers a range of fiberglass window systems for different project needs, including fixed, casement, awning, tilt and turn, slider, single hung, and double hung options.

Best for: residential replacement, custom homes, commercial projects, energy-conscious buyers, and design-focused projects.

Fiberglass Entrance Doors

Inline’s fiberglass entrance doors support curb appeal, durability, and energy performance for premium residential and project-based applications.

Best for: front entries, custom homes, renovation upgrades, sidelites, transoms, and design-driven projects.

Fiberglass Sliding Patio Doors

Inline sliding patio doors are built for larger openings, natural light, and smooth indoor-outdoor transitions.

High-Performance Options

Select Inline products may support high-performance and Passive House project needs. Product suitability, certification details, and documentation should be confirmed with Inline.

Best for: architects, builders, performance-led homeowners, and project teams that need technical product information.

Clear Support for Product Partners

Inline’s dealer program should make it easier for qualified showroom-based partners to understand the product line, present it clearly, and connect customers with the right Inline products.

Depending on the partnership fit, dealer support may include:
