External Flush Door Faces

Our flush exterior doors and frames come in a variety of finishes, each offering unique benefits. Choose pre-finished doors for immediate installation, or select your preferred size, colour and style to create a fully bespoke door. We also offer unfinished doors, which you can paint or stain to your preference. Our door faces include:

• Hardwood Veneer: Hardwood is durable, highly resistant to scratches and comes with a lovely grain. These door faces are heavier and require secure hinges.

• GRP Veneer: A glass-reinforced plastic layer which mimics wood and is highly weather and impact-resistant, offering a cost-effective option with strength and insulation.

• Oak Veneer: An affordable wood face, oak flush doors offer a light brown grain and a resilient nature. These door faces pair well with our oak-veneer door frames.

FAQs about External Flush Doors

Here are a few common questions about our external flush doors for sale. If you have any more, feel free to contact our team.

What finishes do I use on external flush doors?

For the best results, always use supplier-recommended paints and stains to ensure the doors are treated correctly. For wooden veneers, a durable exterior gloss or weather-resistant paint is often recommended. Applying multiple coats ensures long-lasting protection, and painting before installation helps prevent missed areas and uneven coverage.

What are flush composite doors made of?

The exact make-up of flush composite doors can differ depending on the manufacturer and door type. They generally consist of a solid timber or composite core, with an outer skin made from materials such fibreglass, uPVC, foam and laminate.

How do I insulate flush external doors?

Ensure the external flush door matches the handle pack and door frame. This prevents small gaps that allow draughts through. You can also use specialised brush-style draught excluders, with foam or vinyl strips. Avoid installing door furniture such as letterboxes before fitting to maintain insulation.
