In recent years significant changes have taken place to the timescales of building programmes, with ever shortening lead times requiring faster and more innovative building systems.<br> <br> Such a product is Speedset Plus from Premdor. Speedset Plus is a fully adjustable door set with pre hung doors, Premdor explains.<br> <br> The system allows for rapid installation by a lower skilled worker and is easily and quickly adjusted by 10mm to take up variation in wall thicknesses, Premdor says.<br> <br> This system can be supplied direct to site with most Premdor door options, and comes complete with fixing brackets and screws, all of which are hidden by the architrave.<br> <br> The finishing touches are the architraves which are cut to length and mitred yet again saving time and cost of a skilled craftsman.<br> <br> Due to speed and flexibility of the system and the attendant money saving benefits, Speedset Plus has enjoyed success with builders large and small, Premdor says.
