Are you searching for a high-quality breathable felt that offers exceptional value for money? Then you’re in luck, as here at JJ Roofing, we stock and supply exceptional Wonderbuilds WonderVent 140 Premium Breathable Felt – guaranteed to provide that much-needed finishing touch to any roofing project.

Measuring just 0.60mm in thickness, the Wonderbuilds WonderVent 140 Premium Breathable Felt comes in two convenient sizes – 1.5m x 50m and 1m x 50m. So, you’re sure to find a felt that is suited to your specific requirements. The overall weight of this felt is just 140g/m² which is great news as this means it won’t exert any additional strain on your roofing system.

As the name suggests, the Wonderbuilds WonderVent 140 Premium Breathable Felt is brought to you by Wonderbuilds who are a leading and highly respected name in the roofing industry. You can be assured that selecting this felt for your rooftop is a decision that you won’t regret. The felt is manufactured by thermally bonding two layers of non-woven polypropylene with a microporous film between the layers.

This forms a breathable waterproof membrane that will keep out unwanted moisture and protect your home from cold spots. Handling and installation is also a breeze, and this is largely thanks to the lightweight characteristic that means you won’t have to use specialist equipment to lift it into place.

Plus, Wonderbuilds WonderVent 140 Premium Breathable Felt boasts a tear strength of 195/295N. You won’t have to worry about damaging the material during installation, and the felt will stand up to the rigours encountered by most roofing systems. Wonderbuilds are fully BBA certified which means that all of their products come with a high level of assurance.

Here at JJ Roofing, we’re confident that you’ll find our prices to be most competitive. Furthermore, when you place your order for Wonderbuilds WonderVent 140 Premium Breathable Felt with us, you can expect to receive your felt within 3-5 working days.
