Aluminium windows are generally more expensive than uPVC windows, however, they give you more value for your money. Our aluminium windows are supplied with slim sightlines which result in superior views of the outside world. The windows come in a bespoke selection of options, so give your client the choice of stepped, flush stepped, contemporary, or flush contemporary frames.

While uPVC windows are easy to fit and cost-effective, our aluminium windows offer better strength and durability.

Thermal Efficiency

uPVC is a strong insulator of heat, as the double glazing will keep heat inside. However, our aluminium windows offer incredible energy efficiency, as they come with multiple chambers to significantly improve the insulation. Inform your client that this could help save money on costly energy bills.

We also offer triple glazing, which gives customers low U Values of 0.9W/m2K. The U Values are low due to Sheerline’s patented Thermlock technology and full-depth Eurogroove, which makes sure that every property is warmer in the long term. Our windows offer some of the most thermal efficient designs on the market with state of the art technology. This ensures you are making the right choice for your client’s build.


Most uPVC windows are available with advanced double glazing that provides exceptional security standards which could prevent intrusions. At Direct Roofing Systems, all our aluminium windows meet Secured by Design standards. This is an initiative that is supported by the British police to make sure every home or business is protected against intruders, keeping the buildings protected. 

But that’s not all. Feel assured that the sturdy frames will keep you protected from the toughest weather conditions. Our aluminium windows are built to last, with safety measures that are stronger than ever. What’s more, our frames are available with a corner design that seals glass in the unit, giving you excellent protection.


When it comes to maintenance for aluminium and uPVC windows, both are easy to look after. The only thing they need is to be wiped down with a cloth and they will look in excellent condition. Our aluminium windows are some of the strongest on the market.
