The Manthorpe G630 Felt Lap Vent is a refurbishment ventilation product that is fitted retrospectively to assist in overcoming the problems with condensation, often found when additional loft insulation has been recently installed. The product can be easily installed by one person in joist openings from 400mm to 600mm wide to provide 3,000mm² of airflow per unit. The product will not meet the requirement for roof ventilation solely on it's own, it will only provide airflow through the felt laps. Other measures may need to be in place to ensure that the adequate amount of ventilation is provided for the roof space. The specifier should also ensure that the opening of felt laps on the property will not adversely increase the wind uplift load on the tiles/slates or the driving rain resistance of the roof, for more information see BS 5534:2003, 5.8.1 & 6.2.1.1.
Product Benefits

FAQ
All of our C16 and C24 graded timber is regularised
Regularised timber is timber that has been processed to have a uniform shape and size. This means that the wood has been sawn and planed to remove any irregularities and ensure that each piece of wood has consistent dimensions. Regularised timber is often used in construction, particularly in the framing of buildings, as it is easier to work with and can be more efficiently installed than irregularly shaped timber.
We have one of the largest ranges of timber lengths, dimensions and grades available to buy online.
The variation you require will determine the exact lead time and delivery method.
