With a lapped felt construction, it effectively combats condensation build-up while ensuring ease of installation and durability against environmental factors. ## Description 15 x Felt Lap Vents Prevents Loft roof Condensation. Attic Space Ventilation ## Features - The Manthorpe G630 Felt Lap Ventilator is a refurbishment product that is designed to increase the amount of ventilation into existing roof spaces with a lapped felt/ membrane construction. - The product is intended to be fitted retrospectively to properties that have had additional loft insulation recently installed. The vent will help to combat the problem of condensation build up caused by the extra insulation by adding additional ventilation into the roof space. - The product will not meet the requirement for roof space ventilation solely on its own it will only provide airflow through the felt laps into the batten void. - The product has been designed as a remedial solution to help overcome the build-up of condensation in the roof space, however like all products that open the felt lap to provide ventilation it does not meet the code of practice BS 5534:2014+A2:2018 6.2.1.1 - The specifier or user should be aware that the opening of felt laps on the roof may adversely affect the driving rain resistance of the slates, tiles or shingles, as well as increase the wind uplift forces acting on them. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Manthorpe | | Package Dimensions | 30.5 x 23.6 x 11.1 cm; 1.22 Kilograms | | Batteries included? | No | | Batteries Required? | No | | Item Weight | 1.22 kg | ## Images ![Manthorpe Felt Lap Vents Attic Roof Loft Ventilation Cures Condensation 15 Pack - Image 1](https://m.media-amazon.com/images/I/61UAz2PSz0L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Roof vents *by A***R on Reviewed in the United Kingdom on 4 February 2024* Good value easy to fix ### ⭐⭐⭐⭐ 4.0 out of 5 stars Useful but expensive ( with other options!) *by W***. on Reviewed in the United Kingdom on 25 February 2021* These quickly resolved a condensation problem I had in an old house attic . They were however quite expensive for what they were . It is possible to use a cut length(s) of 12mm plastic tube slipped down between the sarking felt and it does exactly the same job by introducing air into the roof space . ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Happy *by B***T on Reviewed in the United Kingdom on 22 January 2021* Well made and did the job --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/250285402-manthorpe-felt-lap-vents-attic-roof-loft-ventilation-cures-condensation](https://www.desertcart.tn/products/250285402-manthorpe-felt-lap-vents-attic-roof-loft-ventilation-cures-condensation) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-23*
