The floor can be designed properly from the start with insulation, screed, pipework or electric matting, floor finish, thresholds and heating controls all considered together.\r\n    <\/p>\r\n    <p>\r\n      It is most worthwhile when you want a clean open-plan layout without radiators taking up wall space, or when the extension has large glazing, bifold doors or a modern kitchen layout where radiator placement becomes awkward.\r\n    <\/p>\r\n\r\n    <div class=\"kws-highlight\">\r\n      <strong>KWS Builders advice:<\/strong> underfloor heating is not just a heating choice. It affects the floor depth, insulation, screed, programme, finishes and heating design.
