L F Replacement Windows Aluminium range of windows and doors offers all you would expect from a quality system - greater comfort, better insulation, minimised maintenance, aesthetically pleasing appearance and enhanced security. In short, the Alitherm product range offers our customers peace of mind and represents a sound investment.

Our exclusive Classic-al range of windows is fully compatible with our Aluminium range.

 The range of windows we provide offer the ultimate in elegance and practicality whether your project is a new build, an extension or a property undergoing renovation.

Our products are particularly suited to developers, architects and builders who want their projects to feature stunning design and future proof products.

At L F we understand that the pressures on every build are different, which is why unlike other aluminium window suppliers we offer our own first class installers for those who need everything taken care of with minimum interruption.

For others who would prefer to handle this part of the project using their own installers, then we are happy to work on a “Supply Only” basis.

We offer what is widely regarded as one of Europe’s leading Aluminium Window Systems and we believe that although it’s not the cheapest product in the market, it will be well worth your while to pay the slight premium on the price.

Aluminium windows offer strength, durability and are highly resistant to rust and corrosion. They provide slim-lines, more glass area and less visible frame. Our aluminium windows are a premium product, maintenance free and built to last, with the life span of aluminium being measured in decades rather than years.

Aluminium is very sustainable endlessly recyclable and very environmentally friendly.

Another benefit of aluminium is the ability for your windows to be coloured any of over 200 different RAL colours. You can even have your windows manufactured to have different colours inside and out. Our Aluminium Products are painted in a polyester powder coat finish, which is baked on for a tough and resilient paint finish that will not flake or fade over time.

We supply a wide variety of aluminium windows from the biggest names in the industry. If you are looking for a feature, or a specific design then please contact us and we can recommend the system that best meets your requirements.
