This modular component seamlessly connects to the main vent body, increasing the effective depth between the external air brick and the sub-floor void. Crafted from UV-stabilised, weather-resistant polypropylene, this extension offers long-term durability even in damp or below-ground conditions. By maintaining a continuous and unobstructed air pathway, it ensures efficient air exchange, drawing in fresh air and expelling moisture-laden air, regardless of deeper foundations or uneven ground levels.\u003c\/p\u003e\u003cdiv style=\"margin-top:30px;\"\u003e\n\u003ch2 style=\"font-size:22px;font-weight:700;color:#1a1a2e;margin-bottom:16px;\"\u003eProduct Specifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;border:1px solid #e0e0e0;border-radius:4px;overflow:hidden;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background:#1a1a2e;\"\u003e\n\u003cth style=\"padding:12px 16px;text-align:left;color:#ffffff;font-weight:600;text-transform:uppercase;font-size:12px;letter-spacing:0.5px;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:12px 16px;text-align:left;color:#ffffff;font-weight:600;text-transform:uppercase;font-size:12px;letter-spacing:0.5px;\"\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:12px 16px;font-weight:600;color:#333;border-bottom:1px solid #e9ecef;width:45%;\"\u003eSales Unit\u003c\/td\u003e\n\u003ctd style=\"padding:12px 16px;color:#555;border-bottom:1px solid #e9ecef;\"\u003eEach\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:12px 16px;font-weight:600;color:#333;border-bottom:1px solid #e9ecef;width:45%;\"\u003eColour\u003c\/td\u003e\n\u003ctd style=\"padding:12px 16px;color:#555;border-bottom:1px solid #e9ecef;\"\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ch2\u003eFeatures \u0026amp; Benefits\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncreased Vertical Adjustment:\u003c\/strong\u003e Extends the reach of the main underfloor vent to accommodate deeper foundations and varying ground levels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecure System Integration:\u003c\/strong\u003e Precision-engineered for seamless connection with compatible vent units, ensuring full airflow continuity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction:\u003c\/strong\u003e Made from high-impact polypropylene, it is resistant to decay, moisture, and soil chemicals for a long service life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreserved Airflow Efficiency:\u003c\/strong\u003e Ensures a clear ventilation path from the external air brick to the sub-floor void.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimplified Installation:\u003c\/strong\u003e Allows straightforward on-site adjustments without the need for bespoke ducting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCost Effective:\u003c\/strong\u003e An economical solution to extend ventilation systems for non-standard depths.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegulatory Compliance:\u003c\/strong\u003e Supports UK Building Regulations, including moisture control and ventilation standards.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSub-Floor Ventilation Extension:\u003c\/strong\u003e Extends the vertical depth of vent systems to reach lower sub-floor voids.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDeep Foundation Adaptation:\u003c\/strong\u003e Ideal for air brick positions above standard height due to uneven ground.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNew Build Installations:\u003c\/strong\u003e Ensures compliant underfloor ventilation in varied foundation designs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefurbishment Projects:\u003c\/strong\u003e Adapts existing systems to meet modern standards or altered floor levels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMoisture Management:\u003c\/strong\u003e Prevents damp, condensation, and timber decay in underfloor spaces.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Guidance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection to Vent Unit:\u003c\/strong\u003e Securely attach to the primary vent body for a tight fit that maintains airflow.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight Adjustment:\u003c\/strong\u003e Stack one or more extensions as needed to achieve desired depth.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"londonbricks-uk.co.uk","offers":[{"title":"Default Title","offer_id":55516343533953,"sku":"MM_LB172","price":9.48,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0687\/5329\/3624\/files\/d6a36e15320a08dad9e75a1597a7037c.png?v=1775833179","url":"https:\/\/londonbricks-uk.co.uk\/products\/telescopic-vent-extension-for-underfloor-ventilation","provider":"London Bricks UK","version":"1.0","type":"link"}
