From 1st July 2013 it was made mandatory in the UK for building products to comply with CE Marking requirements when the current Construction Products Directive was replaced by the Construction Products Regulation. Most external windows and doorsets need CE Marking and it is the responsibly of installers, fabricators and suppliers to comply.
CE marking is a declaration of performance against relevant standards and regulations and is not a quality mark. AccentHansen products have always met high quality demands of the customer and have numerous certifications for security, fire and acoustic performance. In addition, AccentHansen now adhere to the new CE marking requirements for external doors and mark all external doorsets with a CE mark. Declaration of Performances are available on request from AccentHansen.
U-Value'U' values for external non fire and fire rated steel doorsets are listed within Building Regulations and DHF member companies offer CE marked insulated products that are 'U' value rated.
The thermal insulation value of a door is expressed as a 'U'= W(m2)K. The value should only apply only to the entire doorset(inc. frame), not the individual panel section or insulated lath, as detailed in BSEN 12428-2000.
AccentHansen steel doorsets are available with a range of U-values, and have fully certified performance. From a basic 3.6W/m2K for a honeycomb filled 46mm flush door through to an industry leading 83mm high performance acoustic doorset that can achieve upto 1.6W/m2K.
The intended usage of the door should be evaluated before the decision on its ideal 'U' value is taken. For example, it is not necessary for a warehouse doorsets that is in constant use to be highly insulated if it spends most of the time in the open position. It is better to specify a rapid action door with low insulation in this circumstance.
If the building under construction must achieve a 'U' of 0.7 or better it does not necessarily follow that the doorset or roller shutter should meet this 'U' value. Uninsulated products, or products with a lower 'U' value, can be used as long as compensations are made elsewhere in the building design. It is the building itself that must meet overall energy efficiency standards, and the installation of insulated doorsets is just one of many ways of helping to achieve this.
