U-Values:

• ProLite ( softwood frame ) – 2.0W/m2K
• Pro30 ( softwood frame ) – 1.8W/m2K
• Pro60 ( hardwood frame ) – 1.6W/m2K

Additional Installation Instructions:

Guidance for various methods of sealing the frame to structural opening gap is given in BS 8214:2008, code of practice for Timber Fire Door Assemblies.

For exterior applications and in high humidity environments all door edges should be lipped with hardwood using a weather proof glue line.

Three hinges should be fitted for all exterior applications, for doors weighing over 20kg and for interior doors where opposing sides are exposed to extreme variations in temperature and humidity, such as bathrooms and airing cupboards.

When installing in exterior locations, doorframes should be set back from the outer face of the wall, be protected by a canopy or the head of the frame should be provided with a projecting head drip. Particular attention should be given to the protection provided for an outward opening external door.

Painting & Finishing:

At least one of the finishing coats should be applied to exterior doors and frames as soon after delivery or installation as possible. If any deterioration of the applied primer or base coat is detected it should be re-coated before further finishing coats are applied. Finishing of exterior doors and frames should be carried out in dry weather using good exterior quality materials in accordance with the manufacturer’s instructions.

The finish for exterior doors should be exterior quality paint or ‘high build’ stain. ‘Low build’ stains are not suitable for external applications. Please note that if dark coloured paint finishes are used on exterior doors this may result in high surface temperatures on the door and can increase the risk of distortion. It’s important to sufficiently coat the bottom edge of the door before installation to prevent moisture ingress.
