10 x Felt Lap Vents Prevents Loft roof Condensation. Attic Space Ventilation

Product Information

The water literally ran down the felt and dripped off the beams, mould was starting to form and it smelt damp and musty. So, for example, if your roof is 8m long, you would need 8m (=8,000mm) multiplied by 10mm =80,000mm2. Previously, despite built-in vents under the eaves, the loft was slightly damp all year round, and in winter there was a problem with condensation. Daniel Woodley is a former roofer and has over 18 years of experience in the construction and home improvement industries. If you live in a modern house and can't see any evidence of ventilation don't panic, it's there (Building Control insists it's installed) but you may not be able to see it, as it's likely hidden behind your gutters.

This amount includes seller specified domestic postage charges as well as applicable international postage, dispatch, and other fees.Made from an injected molded polypropylene they are a lightweight solution that is fully recyclable. 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.

An incorrectly installed vapour barrier can cause condensation spots on the ceiling and I have seen cases where the condensation in the home went up after the barrier was fitted. G630 Lap vents are fitted inside the loft by simply clipping individual vents onto the edges of the felt or membrane close to the eaves. However, when the loft is cold (from late autumn into winter and spring), the underside of the roofing felt and the timbers will be cold.Well it’s true and I know because I worked as a roofer for 17 years and have fitted this product to hundreds of lofts but you don’t need to pay for a roofer. These are the same tiles that provide a terminal for soil vent pipes or mechanical extraction units most commonly bathroom extraction. It can be hard to tell if it’s condensation or the roof is leaking, particularly as it can be astounding how much moisture can condense in the right (or should we say, wrong) conditions. Essentially there are two elements to dealing with condensation; the first is to understand where comes from, and the second is how it is removed from your home. Every winter, people go into their lofts to put away items they won’t need until next year or to take out the Christmas decorations.
