the gap had been filled with mortar, a material that does not meet the thermal requirements of an insulating material.<\/p>\n<p>Please note that <strong>all of this can perfectly well be claimed <\/strong>if you are within the time limit. <a href=\"https:\/\/dpcon.es\/en\/contact-us\/\">Get advice<\/a>.<\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=&#8221;1&#8243;
