Doors FAQs

Most frequent questions and answers about doors in Dundee

Indeed, our Dundee uPVC doors can be customised to include glass panels, which can add a touch of charm and elegance to your home. Whether you’re looking to let more natural light into your space, want a clear view of your outdoor area, or desire a beautiful design feature. Notably, we offer double and triple-glazed glass options. 

This offers an excellent balance between aesthetics and functionality, as double and triple-glazing provide excellent insulation and noise reduction. So, when opting for a uPVC door with a glass panel, you won’t have to compromise on energy efficiency or comfort.

Although uPVC doors are celebrated for their durability and minimal maintenance, it’s typically not advisable to paint or stain them. The material’s surface is non-porous, meaning paint or stain may not adhere well, leading to peeling or flaking over time. 

However, the beauty of uPVC doors lies in their wide range of colours and finishes available from the outset. You can select a design that perfectly aligns with your home’s exterior without the need for extra customisation.

Definitely, uPVC doors are an excellent choice for patio or balcony entrances. Their robust nature makes them capable of withstanding various weather conditions, including rain, snow, and even intense sunlight, without warping, cracking, or fading. Moreover, the high insulation properties of uPVC doors make them ideal for these larger openings, helping to maintain the internal temperature of your home regardless of the season. This means you can enjoy your patio or balcony view year-round without worrying about drafts or heat loss.

Yes, uPVC doors possess impressive resistance to UV light. This is a significant advantage over wooden doors, which can fade or discolour when continuously exposed to the sun’s rays. uPVC doors are designed to maintain their vibrant colour and sleek finish for years, requiring minimal maintenance. This makes them a long-lasting and practical choice for any home, ensuring you enjoy the aesthetic appeal of your doors for many years to come.

One of the key benefits of choosing uPVC doors is their ease of maintenance. Their smooth surface makes cleaning a breeze; a quick wipe with a damp cloth and mild detergent is usually enough to keep your uPVC door looking fresh and clean. It’s best to avoid harsh chemicals as they may damage the surface finish, but most marks or dirt can be easily removed with warm soapy water. So, even if your doors are exposed to the elements, you’ll find that maintaining their appearance is a simple, straightforward task.

Absolutely, uPVC doors are highly resistant to insects and other small pests. Unlike wood, which can be prone to infestation by termites or other wood-boring insects, uPVC is an unappealing material for pests. It doesn’t absorb moisture, which is a major attraction for many types of insects. With a uPVC door, you can have peace of mind knowing that it serves as a steadfast barrier against unwelcome critters, contributing to the overall wellbeing of your home environment.

Yes, uPVC doors can indeed assist in reducing condensation in your home. The insulating properties of uPVC and its typical pairing with double or triple glazing mean that there is less of a temperature difference between the interior and exterior surfaces of the door. This effectively reduces the likelihood of condensation forming, which usually happens when warm air comes into contact with a cold surface and cools rapidly. With a uPVC door, the inner surface of the door remains closer to room temperature, thereby minimising the chances of condensation, keeping your living spaces clearer and more comfortable.

A multi-point locking system is a high-security feature often found on uPVC doors. This system involves multiple locks engaging at different points along the door and frame when you turn the key or handle. Instead of relying on a single lock, a multi-point system spreads the locking points, distributing the force exerted when someone tries to force the door open, thereby significantly increasing security. This feature can deter potential intruders and provide homeowners with an added level of safety and peace of mind. When combined with the robustness and durability of uPVC doors, a multi-point locking system helps create an extremely secure entrance to your home.
