INTRODUCING<\/h2>\n

[\/vc_column_text][vc_column_text css=””]<\/p>\n

Rytons A1\u00ae FlowRyt\u00ae Air Brick Extender<\/h6>\n

[\/vc_column_text][vc_column_text css=””]We are often asked how to maintain sub-floor ventilation when existing air bricks become obstructed by patios, paving, landscaping or raised ground levels. Restricted airflow beneath suspended floors can lead to moisture build-up, condensation, and timber decay, making effective ventilation essential. However, until now, there has been no simple retrofit solution.<\/p>\n

To address this challenge, Rytons A1\u00ae FlowRyt\u00ae Air Brick Extender<\/strong><\/a> has been developed to raise air intake above finished ground level and help improve underfloor ventilation.<\/p>\n

Designed for retrofit applications, the two-piece grille and back plate system can extend ventilation by up to three brick courses. Installed at existing air brick locations, it requires only minimal clearing and cutting around the air brick, helping to reduce installation time and disruption. The FlowRyt\u00ae grille design provides a high free area of 8,000mm\u00b2, to help maximise ventilation to the sub-floor void.<\/p>\n

Manufactured from A1 classified non-combustible galvanised steel, the unit offers long-term strength and durability. It is finished with a Class A2-s1, d0 powder coating and is available in three RAL colours, with additional colours available on request. Colour-matched screws are supplied for a neat finish.[\/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\/2″ 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=”49342″ img_size=”large” style=”vc_box_rounded” css=””][\/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_column][\/vc_row][vc_row rt_row_background_width=”default” rt_row_style=”default-style” rt_row_borders=”” rt_grid=”true” 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\/3″ 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_text css=””]<\/p>\n
