{"title":"Louvre Vent","description":"\u003cp\u003eShop our full range of louvre vents, the angled slat ventilation covers used to keep air moving through walls, doors, ducting and outbuildings while keeping rain and debris out. Our louvre vent range covers plastic and aluminium options in 9x3 inch, 9x6 inch and 9x9 inch sizes, circular louvred vents, and louvred ducting grilles with spigots for kitchen, bathroom and utility extraction points, in white, brown, black and grey finishes.\u003c\/p\u003e\u003cp\u003eA louvre vent works through a simple set of angled slats, usually set between 30 and 45 degrees, that let air pass freely through the opening in both directions while the angle of the slats sheds wind driven rain and stops larger debris being blown through. It is one of the simplest and most reliable ways to provide background ventilation to a room, subfloor void, shed or garage, and is a common requirement under UK building regulations for controlling condensation, damp and mould in enclosed spaces.\u003c\/p\u003e\u003cp\u003ePlastic louvre vents are the lightweight, cost effective choice for general background ventilation and come with either a fixed or removable flyscreen to keep flies and larger insects out. Aluminium louvre vents cost a little more but are stronger, more weather resistant, and are the ones rated suitable for venting gas appliances, since plastic is not rated to sit close to flue heat. Whether you need a straightforward airbrick replacement, a vent for a shed or greenhouse, or a louvred grille to finish a ducting run, you will find the right size and finish in this collection.\u003c\/p\u003e","products":[{"product_id":"securit-white-plastic-louvre-vent-9-x-6","title":"Securit White Plastic Louvre Vent 9 x 6 Inch - Fixed Flyscreen","description":"\u003cp\u003eThis Securit white plastic louvre vent is a 9 x 6 inch (approximately 229 x 150mm) ventilation cover designed to fit into an airbrick opening, plaster vent frame, or door to provide background ventilation for suspended timber floors, sub floor voids, utility rooms, and outbuildings.
