This listing is for a quality commercial hollow core internal door. Our doors are manufactured to the highest standard and are finished with quality real-wood veneer, or a smooth paint-ready finish, depending upon your selection. Real-wood veneers are a naturally occurring product and natural variation in finish is characteristic and a desirable feature in all cases. If you require matching doors, which is a particularly common when ordering pairs of doors for double sets, a book matching service is available at an extra cost. Our doors are constructed with high quality wood and wood derivatives, and are available in a range of stiles, designs and finishes. Our internal doors are compatible with a huge range of ironmongery, from anti-panic bars, suited locks, self-closing control gear, to electronic locks and access control products. All these components are readily available from Nationwide. Our fire doors are fully certified and independently accredited. Cellular or Hollow Core doors cannot be fire rated. Where higher levels or acoustic performance are required we have a range of tested door-sets and complimentary hardware to achieve sound reduction levels of up to 45dB, system dependent. These levels of sound insulation may require upgrading to a solid core door. All vision panels are factory fitted with complimentary beading and fire accessories. All modifications to fire rated doors and door-sets are carried out by qualified and certified engineers. Full certification is available upon request. Our doors and frames are guaranteed for 10 years against faulty materials or manufacture, provided that doors are maintained according to our recommendations. Our guarantee period begins from the date of invoice and stipulates that said products, when sold as new, are in accordance with the manufacturer's technical speci?cations and free from defects in materials or workmanship. Should you have any questions or require help selecting the correct door configuration to meet your requirements please contact us directly and speak to a member of our sales team who will be able to advise you. . .
