Monmouth's first choice for composite doors

Composite Doors Monmouth

Home to beautiful structures like Shire Hall and Monnow Bridge, Monmouth is a market town that’s full of character. So if you’re a Monmouth homeowner, you’ll be eager to emulate the town’s charm within your own property. If you’re looking to change the exterior of your home by fitting a new front door, then Thermotech has a vast selection of elegant composite doors that are sure to look beautiful, whatever style of property you live in.

A door style for every type of property

With over 20 different door styles, and seven different colours to choose from, Thermotech has the best selection of composite doors south Wales has to offer. So whether you live in one of Monmouth’s iconic Georgian townhouses, or a picturesque cottage overlooking the River Wye, you’ll be able to find a door in a style and colour that blends in perfectly with your home’s exterior. Even if you live in a more modern dwelling, there is plenty of choice if you want to give your home’s exterior a bit of a facelift.

Classic charm with modern features

Composite doors combine the best of both worlds: stylish design and the latest technological developments. Comprising of a solid timber frame that’s reinforced with an ultra-tough material such as galvainised steel, your new front door will provide your home with a strong and secure entrance way. The outer frame is made from high-quality uPVC, which is usually designed with a woodgrain pattern to make it appear more like a traditional wooden door.

Safe and secure

Even if you don’t live in a fortified building like Monmouth Castle, Thermotech believes all their south Wales customers should feel safe and secure in their homes. That’s why all the composite doors we sell come fitted with the best security locking systems that are currently available on the market. This, combined with the door’s reinforced frame, will ensure that potential intruders remain on the outside of your property.
