When it comes to delivering quality, performance and reliability in home improvement, the choice of composite door manufacturer can make all the difference—especially for installers and trade professionals.
Sliders UK supplies exclusively to registered installers and tradespeople, offering high-quality composite doors built to perform, backed by technical support, and delivered with the needs of professionals in mind.
What Is a Composite Door?
A composite door is engineered using multiple materials—typically a solid timber core inside a uPVC or GRP (Glass Reinforced Plastic) skin. The result? Exceptional strength, energy efficiency and minimal maintenance.
Ideal for front or back door installations, composite doors offer:
- Outstanding thermal efficiency
- High-level security features
- Weather resistance and longevity
- A premium appearance with versatile design options
