Can I get aluminium windows and doors in different colours?

Absolutely! Aluminium windows and doors can be powder-coated in a wide range of colours to match your home's aesthetic. You can choose from standard colours or custom options to create the perfect look.

Why might I want inward-opening windows?

Inward-opening windows are particularly easy to clean and provide ventilation control. They are also safer for upper floors and can be fitted with secure locking mechanisms. If you have limited outdoor space or obstacles like trees or balconies, inward-opening windows can be a practical solution.

Your questions answered

Are aluminium windows and doors energy-efficient?
Yes, modern aluminium windows and doors are designed with thermal breaks and advanced glazing options that provide excellent insulation. This helps to keep your home warm in the winter and cool in the summer, reducing energy costs and increasing comfort.
Can aluminium or steel windows and doors be customised?
Yes, both materials offer great flexibility in design. You can customise the size, shape, and finish to suit your specific needs and preferences. This allows for unique architectural designs and personal touches.
What are tilt/turn windows?
Tilt/turn windows are European-style windows that open in two ways: They tilt inwards with an opening at the top for controlled ventilation and swing inwards for easy cleaning and access. Known for their modern design and versatility, these windows provide greater flexibility and can often be constructed larger than casement windows.
