However, replacing the ductwork can be complex if there is no access to the apartments. No access. No problem with Rytons A1\u00ae Fire-rated Retrofit Ducting Kits.<\/p>\n
Whether the requirement is for round or rectangular ductwork, we have a comprehensive range of non-combustible, A1 classified, retrofit ducting kits. Unlike our standard kits which pass through the cavity board to the inner leaf, retrofit kits are fixed to the cavity board by a wide flange at the end of the duct. The oversized metal ducting then encases and protects in-situ plastic ducting that passes through the cavity board and cannot be replaced due to access issues.[\/vc_column_text][\/vc_column][\/vc_row][vc_row rt_row_background_width=”default” rt_row_style=”default-style” rt_row_borders=”” rt_row_paddings=”true” rt_bg_effect=”classic” rt_bg_image_repeat=”repeat” rt_bg_size=”cover” rt_bg_position=”right top” rt_bg_attachment=”scroll” rt_bg_video_format=”self-hosted”][vc_column width=”1\/4″ rt_wrp_col_paddings=”false” rt_border_top=”” rt_border_bottom=”” rt_border_left=”” rt_border_right=”” rt_border_top_mobile=”” rt_border_bottom_mobile=”” rt_border_left_mobile=”” rt_border_right_mobile=”” rt_bg_image_repeat=”repeat” rt_bg_size=”auto auto” rt_bg_position=”right top” rt_bg_attachment=”scroll”][\/vc_column][vc_column width=”1\/4″ rt_wrp_col_paddings=”false” rt_border_top=”” rt_border_bottom=”” rt_border_left=”” rt_border_right=”” rt_border_top_mobile=”” rt_border_bottom_mobile=”” rt_border_left_mobile=”” rt_border_right_mobile=”” rt_bg_image_repeat=”repeat” rt_bg_size=”auto auto” rt_bg_position=”right top” rt_bg_attachment=”scroll”][vc_single_image image=”43766″ alignment=”center” style=”vc_box_outline_circle” onclick=”img_link_large” img_link_target=”_blank”][vc_column_text]<\/p>\n
