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:
- Homeowners upgrading windows and doors
- Builders working on custom homes and renovations
- Architects and specifiers looking for technical product confidence
- Commercial and high-performance project teams
- Customers looking for fiberglass instead of vinyl, aluminum, or wood alternatives

Clear Support for Product Partners

Depending on the partnership fit, dealer support may include:
- Product information and sales resources
- Technical documents and specification support
- Dealer training on Inline product offerings
- Product samples and showroom displays
- Dealer locator visibility for approved partners

01 — Tell Us About Your Business
Submit your dealer inquiry with your company details, market area, product interest, and the type of customers you serve.
02 — Inline Reviews Market Fit
The Inline team reviews your business, showroom presence, target market, and product interest. Inline is currently accepting new dealer inquiries and does not offer exclusive territories at this time.

Approved dealers can receive guidance on product resources, product training, display or sample availability, dealer locator listing, and how to represent Inline products accurately.
Become an Inline Dealer or Distributor
This page is for showroom-based companies that sell, distribute, specify, or support premium window and door products.
Inline may be a fit for:
- Window and door dealers with a showroom
- Building product distributors with a showroom or display space
- Window and door showrooms
- Building envelope product suppliers
