The process that Paxton Restoration uses to draught proof has been tried and tested over the years and provides excellent results. The nylon brush pile is inserted into a channel on the rear of the staff bead and parting bead. This brush pile is made of high density polypropylene yarn, is siliconised to repel water and is tested to BS7386.
Our draught proofing is discreet, simple and has a minimum lifespan of 10 years. Without draught proofing, a building with sash windows may have 2.5 – 3.0 air changes per hour, with draught proofing, air change rates are significantly reduced to 0.4 per hour – a 750% fold improvement.
