I decided to upgrade my windows with Horizon. John, the salesperson who visited my house, was incredibly knowledgeable and explained all the different security features their windows offered. I ended up getting windows with multi-point locking mechanisms, and I feel so much safer now! Plus, the windows are really sleek and modern-looking, which was a nice bonus. Horizon's service was top-notch from start to finish, and I wouldn't hesitate to recommend them to anyone looking for new windows.

The constant Dublin street noise was driving me crazy! I finally decided to invest in new windows from Horizon, and I'm so glad I did. Their entire process, from the initial consultation with David to the installation, was smooth and professional. The windows themselves are fantastic - they've made a huge difference in how much noise comes into the house. Now I can finally relax and enjoy some peace and quiet in my own home.

Plus, I'm sure I'll see a reduction in my energy bills this winter.

FAQ’s​

To tell if a door is composite is by examining the materials and construction. Composite doors are typically made from a combination of materials like uPVC, wood, insulating foam, and GRP (glass-reinforced plastic). Key indicators include: 

Multi-layer construction: Look for layers or a mix of materials when inspecting the edge of the door. 

GRP skin: Composite doors often have a woodgrain effect with a tough, durable GRP outer skin, which feels different from solid wood or metal. 

Insulating core: Composite doors typically have a dense foam core, which provides excellent insulation. You can sometimes identify this by checking the weight or feel of the door. 

Weight: Composite doors tend to be heavier than uPVC doors but lighter than solid wood doors due to the mixed materials. 

Composite doors typically last 20 to 30 years or more, depending on the quality of materials and installation.

Yes, composite doors are designed to be waterproof. They are made from a combination of materials like uPVC, wood, and insulating foam, with a durable outer layer typically made of GRP (glass-reinforced plastic). This GRP skin provides excellent resistance to water and prevents swelling, warping, or rotting, which is common in traditional wooden doors. The multi-layered construction and weather seals on composite doors also enhance their ability to keep water out, making them highly effective in wet or harsh weather conditions.

Composite doors are generally designed to be highly resistant to leaks, thanks to their durable construction and weatherproof seals.

Yes, the sun can affect composite doors, but they are designed to withstand UV exposure better than many other door materials. High-quality composite doors have a durable GRP (glass-reinforced plastic) outer layer, which is resistant to fading, warping, and cracking from sunlight. However, prolonged and extreme exposure to intense sunlight over many years can cause minor fading or discoloration, especially with darker-colored doors.

Yes, composite doors are better than wood. They offer superior durability, better insulation, enhanced security, and require minimal maintenance. Unlike wood, composite doors won’t warp, crack, or rot, and they maintain their appearance without needing regular upkeep. While wood doors may have classic appeal, composite doors provide a more practical, long-lasting solution with modern benefits like energy efficiency and weather resistance.

No, composite doors do not typically split. They are made from a combination of durable materials, including uPVC, wood, insulating foam, and GRP (glass-reinforced plastic), which prevents splitting. The multi-layered construction of composite doors is specifically designed to resist common issues that affect wooden doors, such as splitting, warping, or cracking, even in extreme weather conditions. With proper installation and care, composite doors remain intact and highly durable over time. 

No, composite doors are generally not noisy. In fact, they are designed to provide good sound insulation due to their multi-layered construction, which includes materials like high-density foam, uPVC, and a durable GRP (glass-reinforced plastic) outer layer. These materials help block external noise, making composite doors quieter compared to some other door types, like hollow uPVC doors. If installed properly, composite doors should reduce noise levels and contribute to a quieter indoor environment.

No, composite doors do not scratch easily. The outer layer of a composite door is typically made of GRP (glass-reinforced plastic), which is highly durable and resistant to scratches and everyday wear. This tough outer skin is designed to withstand impacts and environmental factors like weather and UV exposure. However, like any surface, if subjected to sharp or abrasive objects, minor scratches can occur, but they are generally less noticeable compared to other materials. Regular care and cleaning can help maintain the door’s finish and appearance.
