Preserving the charm and integrity of heritage buildings requires a delicate balance of respect for the past and modern upgrades for real-world functionality. When it comes to choosing the right windows for heritage buildings, fiberglass offers a compelling blend of historical accuracy, performance, and long-term value.
The Beauty of Fiberglass: A Nod to the Past
- Historic Accuracy: Fiberglass windows can be meticulously crafted to replicate the look of traditional wood windows, complete with intricate profiles, classic muntin patterns, and rich woodgrain finishes.
- Colour Customization: Fiberglass offers a vast colour palette, perfectly matching your heritage building’s original scheme. Companies like SunRay understand the importance of colour accuracy for heritage spaces and Duxton Windows, our supplier can accommodate almost any colour or style.


Why Fiberglass Outperforms Traditional Materials
- Unmatched Durability: Unlike wood, fiberglass won’t succumb to rot, warping, moisture damage, or insect infestations. This helps maintain the structural soundness of your heritage building.
- Weather Resilience: Fiberglass handles extreme temperature swings without significant expansion or contraction, minimizing the risk of air and water leaks.
Windows for Heritage Buildings: Energy Efficiency Matters
- Superior Insulation: Fiberglass is naturally energy-efficient, and when paired with advanced glazing options, it drastically outperforms single-pane windows common in heritage structures. SunRay Windows specializes in windows ideal for colder climates.
- Improved Comfort, Lower Bills: Airtight fiberglass windows help regulate indoor temperatures and reduce energy waste, saving money.
Minimal Maintenance, Maximum Lifespan
- Easy Care: A simple cleaning routine keeps fiberglass windows looking pristine—no laborious sanding or repainting necessary.
- Built to Last: High-quality fiberglass windows and doors installed properly can last for decades, adding value to your heritage property.
