Modern Heritage Windows & Doors

Timeless Appearance

We understand that the crittall windows and doors look can bring out the best in a property, or it may have become ingrained in the character of the building. Our range of heritage double glazing is designed to reflect the crittall style that is becoming more popular. They can be applied to both new and old buildings alike to bring a complementary feature that is sure to be worthwhile. Opt for us for the perfect fit today!

Thermally Efficient

Unlike the double glazing that they emulate, our heritage windows and doors have been designed to achieve an impressive level of thermal efficiency. This is made possible via an intelligently designed polyamide bridge, which is fitted into the aluminium profile to prevent heat loss from your property by increasing heat retention. With this, you’ll be able to keep the winter winds out without reducing the style of your home.

Highly Secure

To ensure you feel more comfortable in your home, all our crittall style windows and doors can offer an exceptional standard of inherent security to keep you safe. This is enhanced by high security, multi-point locking system that we integrate into the frame to ensure outstanding security is kept consistent across the whole frame. These windows will be able to withstand prolonged attack, even from the most determined intruder. Enjoy peace of mind in a classic way, with Direct Trade Windows.

Designed to Last

Standing as a modern alternative to timber windows, our heritage windows are manufactured from materials that won’t rot, warp, discolour, bow or crack over time or when exposed to the weather. Our windows will prove to be a fantastic investment for your home, continuing to bring value time and time again. All colours are applied with a durable powder coating which prevents them from flaking or fading, so you’ll also be able to enjoy a full and vibrant look.

Crittall Style Windows & Doors

Crittall windows and doors are an increasingly popular style of heritage windows & doors. This is because they offer a form that can be adapted to suit both contemporary and traditional structures. They offer style for both residential and commercial properties too.

As a stylish way to separate larger rooms without making space seem smaller, why not opt for crittall windows and doors? They offer an attractive solution helping to create more dynamic space. For those who love interior design choose these ideal and stunning modern fit today. Get in touch for more information.
