A material that stands the test of time

Aluminium windows and doors

Technology has evolved

Undoubtedly more durable than PVC, aluminium also provides superior insulation for doors and windows. Plus, technology has improved over the years—aluminium doors and windows can be on trend too. Whether it’s the wide range of colours that don’t fade over time, or the option for larger windows in offbeat designs, aluminium doors and windows will have what you’re looking for.

Reviews from our customers

I had three windows replaced in my house by David and his team. They arrived at 7am and were finished by 10:30 am. They both worked very hard and the house was very clean when they left. They were both very polite and very knowledgeable about the product they were installing. Thank you GIT for a great experience, I would recommend GIT products and service any time.

Very efficient. I had my kitchen window enlarged and replaced the main bathroom windows. They did a super job. Would definitely order my next window/s with Eco Lite. Faran is a pleasure to work with and very professional.
