Window Glass Gets the Attention. The Frame Matters Too.

Two low-maintenance frame materials homeowners may compare are:

• Vinyl
• Fibreglass

Vinyl Windows

Vinyl is popular because it is generally:

• Low maintenance
• Cost accessible
• Available in many configurations
• Thermally efficient when properly designed

Fibreglass Windows

Fibreglass offers:

• High strength
• Good dimensional stability
• Resistance to rot and corrosion

Pella describes fibreglass as generally stronger and more weather-resistant than vinyl, although usually at a higher upfront price.

Is One More Energy Efficient?

Do not judge by material name alone.

Performance depends on:

• Frame design
• Glass
• Spacers
• Air leakage
• Installation

Use the actual U-factor and Energy Rating where available.

Which Should You Buy?

Compare:

• Budget
• Available product lines
• Colour
• Window size
• Maintenance
• Performance ratings

Window Material Is One Part of the Complete Unit.

Envirotech Exteriors can help homeowners compare available window systems using actual performance rather than assuming one frame material always wins.
