In direct response to the increasing trend to improve the insulation of our homes in order to improve energy efficiency and thereby help to reduce energy bills, we’ve introduced WARMER DOOR, a range of Part L compliant external doors, that are fully factory finished with the acclaimed Sikkens Finishing system, so they can be purchased and hung as a replacement door without the need for further finishing (NB - hinge and lock cut-outs and/or planed edges must of course be resealed to ensure the integrity of the door is maintained and the LPD Guarantee is validated).

What’s more, because each model has been independently tested and certified as achieving full Part L compliance, WARMER DOOR can be specified on new build projects too.
