High-quality and energy-efficient aluminium windows
What makes heroal aluminium windows superior?
Whether it is a new house, a renovation or a modernisation project: heroal aluminium windows offer almost unlimited design possibilities for enhancing the appearance of your property. With aluminium windows, you get high-quality, integrated solutions with low maintenance requirements and high durability.
For effective burglar resistance, the police recommend at least burglar-resistant windows of resistance class RC 2. heroal security windows offer you burglar protection up to resistance class RC 3. Combined with heroal security roller shutters, you can even achieve resistance class RC 4.
Insufficiently insulated windows often result in costly energy loss. Aluminium windows by heroal minimise energy loss with their optimum profile construction and fitting technology. Replacing old windows is an investment that pays off in the long term. As an added benefit, it visually enhances your property.
