You may ask, “Are fibreglass doors more expensive than steel?” The answer is “They can be”. While the initial cost can be higher, the durability often outweighs this concern.

Extra Safety and Security

For extra safety and security, consider adding features like reinforced locks and tempered  glass to your chosen door. These additional features can provide you with peace of mind and protect your home and loved ones from potential intruders. Reinforced locks are designed to withstand forced entry attempts, making it much more difficult for burglars to break into your home.

Tempered glass, on the other hand, is designed to prevent break-ins by making it nearly impossible for intruders to gain access through the door. By investing in these security features, you can create a strong barrier between your home and the outside world, ensuring that you and your family feel safe and secure.
