What Information Is Required to Get a Building Envelope System Quotation?

Obtaining an accurate building envelope quotation is an important step when planning an industrial facility, airport terminal, hospital, sports arena, commercial building, or steel structure warehouse.

A building envelope system includes exterior wall and roofing materials that protect the building from external weather conditions while meeting architectural and performance requirements.

However, requesting a quotation involves more than providing the total wall or roof area. Manufacturers need to understand the building design, panel specifications, supporting structure, and required installation accessories.

For construction projects, architectural drawings and structural drawings are recommended for detailed material calculations. For distributors and wholesale buyers, product dimensions, quantities, and accessory lists can be used to request a quotation without complete construction drawings.

This guide explains what information to prepare, how building envelope materials are calculated, and how Glostar supports international construction projects.

1. What Is Included in a Building Envelope System Quotation?

A building envelope quotation can cover different products depending on the project application and agreed supply scope.

Typical materials include:

The quotation should clearly identify which components are included and which are excluded.

For preliminary quotations, provide the estimated exterior wall and roof areas in square meters.

If available, include a bill of quantities (BOQ) or panel schedule.

Also specify the expected purchasing date, delivery destination, and whether the quotation should include accessories.

3. What Architectural Drawings Are Required for a Building Envelope Quotation?

For project-based material calculations, Glostar recommends providing architectural floor plans, elevation drawings, and section drawings.

These drawings help the technical team understand the building geometry and determine the required materials.

3.1 Architectural Floor Plans

Floor plans show the overall building layout, dimensions, and arrangement of major building elements.

They help identify building length and width, exterior wall locations, building perimeter, and major openings.

3.2 Architectural Elevation Drawings

Elevation drawings are particularly important for facade material calculations.

They show:

• Exterior wall heights
• Facade panel arrangements
• Door and window locations
• Architectural projections and recesses
• Different facade materials and colors
• Panel installation directions

Elevation drawings help the technical team calculate facade panel quantities and identify locations requiring metal flashing, corner trims, and customized connection details.

3.3 Architectural Section Drawings

Section drawings show the relationships between walls, roofs, floors, and supporting structures.

They help identify:

• Wall-to-roof connections
• Roof slopes and levels
• Eave and parapet details
• Wall base connections
• Roof and facade interfaces
• Insulation and weatherproofing requirements

These details are important when calculating metal flashing, sealing materials, and installation accessories.

3.4 Roof Plans and Construction Details

For roofing projects, roof plans help identify:

• Roof dimensions and slopes
• Ridge and valley locations
• Eaves and parapets
• Roof openings and penetrations
• Drainage arrangements
• Roof panel installation directions

These details help determine roofing material quantities and accessory requirements.

4. Why Are Structural Drawings Important?

Structural drawings show how the building envelope connects to the supporting framework.

Useful information includes:

• Steel column and beam layouts
• Wall girt spacing
• Roof purlin spacing
• Supporting framework dimensions
• Structural connection locations
• Relevant design loads and movement requirements

For example, wall girt spacing influences panel spans and fixing arrangements, while roof purlin spacing affects roofing panel selection and fastening requirements.

Architectural and structural drawings should be reviewed together to prepare a more accurate building envelope material calculation.

If your project also requires the primary steel structure, read our related guide:

This article explains the information required for steel structure quotations, including building dimensions, structural loads, crane requirements, and supporting design information.

5. What Product Specifications Should You Provide?

Product specifications directly influence building envelope material costs.

Panel Thickness and Insulation

Panel thickness and insulation material should be selected according to the building application and project requirements.

For insulated wall and roof systems, provide the required thermal performance, fire performance, and panel thickness where available.
Thermal insulation performance is an important consideration when selecting building envelope materials. For general guidance on insulation performance and thermal resistance, refer to the U.S. Department of Energy’s Insulation Guide.

Explore Glostar’s Rock Wool Sandwich Panels for relevant product options. 

Panel Width and Length

Available panel widths and maximum lengths depend on the selected product system, manufacturing capabilities, and transportation restrictions.

For large projects, panel dimensions should be coordinated with the architectural layout and supporting structure.

Surface Coatings and Colors

Glostar offers different coating and color options according to the selected building envelope system.

Customers can provide RAL color references, architectural finish requirements, or project specifications.

Final coating and color availability should be confirmed before production.

6. How Does Glostar Calculate Metal Flashing and Installation Accessories?

A complete building envelope quotation should consider not only the main wall and roof panels but also the materials required for installation.

Based on architectural and structural drawings, Glostar’s technical team can assist with calculating metal flashing, fasteners, sealing consumables, and other installation accessories.

6.1 Metal Flashing and Folded Components

Metal flashing is used to finish building edges, protect interfaces, and support weatherproofing details.

Common components include:

• External and internal corner flashing
• Ridge caps
• Eave flashing
• Parapet flashing
• Window and door opening trims
