Alitherm Heritage aluminium windows have been designed to offer a modern solution to traditional steel windows and are most often used for listed building renovations and large scale replica-refurbishment projects where regulations demand a like-for-like replacement.

Because our range of aluminium windows features signature slim sightlines and attractive contours, they are the most popular choice for heritage building conservation areas

Why choose aluminium?

Alitherm Heritage aluminium windows will give you peace of mind and are a sound investment for anyone looking to upgrade.

They are aesthetically pleasing

Alitherm Heritage aluminium windows have an ultramodern appearance. They have slim, sleek frames, allowing for more light in the room and providing more glass than frame. Filling a room with natural light can make it appear larger and feel brighter. 

Not to mention resilient

Because aluminium is so strong, but also lightweight, it holds larger panes of glass compared to other window materials. It's also an extremely durable material, giving you windows that will last for years to come

And energy efficient

The efficiency of Alitherm Heritage aluminium windows is unbeatable. With a thermally broken profile, insulation is quickly boosted - and with higher insulation comes lower bills. You can say goodbye to draughts and hello to a comfortable temperature.

They are virtually maintenance free

The durability of aluminium means Alitherm Heritage windows are very easy to look after and they will look pristine all year round. Aluminium windows won't rust, corrode or fade.

You can choose your colour to suit your style

 Alitherm products are available in a choice of standard or non-standard colours, including metallic, dual colour, Smart’s Sensations textured, and Alchemy anodised effect finishes - so regardless of your taste or style, there will be something for you. Whatever colour you choose will stay looking good for years to come.

They offer high security, too

Security is a priority for all property, that's why Alitherm Heritage windows come with effective locks to provide maximum safety. Aluminium’s strength is a further barrier against intrusion.

If that wasn't enough - they are environmentally friendly

Protecting the environment is important to us and choosing aluminium is the environmentally friendly choice. Aluminium is recyclable and our manufacturers follow rigorous recycling processes as well as doing their best to become carbon neutral.
