Technical Confidence Starts With Clear Product Information
Architectural projects need more than attractive windows and doors. They require products that align with the design intent, performance targets, budget, schedule, and overall building envelope strategy.
Inline Fiberglass helps architects, specifiers, builders, and project teams navigate key specification decisions early in the process by providing access to product data, performance information, CAD drawings, PDF details, and technical guidance.
The goal is to make specification decisions clearer and more efficient before the project advances into tendering, procurement, or construction.
Built Around Fiberglass. Supported With Documentation.
Inline Fiberglass is focused on fiberglass windows and doors for projects where long-term performance, comfort, durability, and clean design matter.
For architects and specifiers, that focus matters because the product decision is not just visual. It affects thermal performance, dimensional stability, glass selection, envelope detailing, and long-term building operation.
Available technical support may include:
- Product specifications
- Window CAD drawings and PDF details
- Performance documents
- Glazing and configuration information
- Certification documents where applicable
- Passive House / PHIUS-related product information where applicable
- AAMA, NFRC, IGMAC, and other certification references where applicable
- Commercial and high-performance project examples
- Guidance on product selection, sizing, colours, and options
A Material Choice That Supports Performance and Design
Fiberglass windows and doors are often selected for projects where ordinary window materials may create design or performance trade-offs. Inline fiberglass products are designed to support:
Thermal performance
Fiberglass helps reduce unwanted heat transfer through the frame, supporting better building envelope performance and improved thermal efficiency
Dimensional stability
Fiberglass expands and contracts at a rate closer to glass than many common window frame materials, helping support long-term unit stability.
Strength and slim profiles
Strong frame materials can help support larger glass areas and clean sightlines, depending on the selected product series and project requirements.
Design flexibility
Inline offers fiberglass windows, entrance doors, sliding patio doors, glass options, colours, grilles, and hardware choices for a range of residential and commercial applications.
High-performance goals
Select Inline products may support Passive House, PHIUS, and high-performance project requirements. Contact Inline to confirm the right product, certification detailsfor your project.
Technical Support
Access product data, CAD drawings, installation resources, and technical guidance to support specification, coordination, and project planning before getting started.
