BMI Redland Veltitech 145

If you’re looking for exceptional roofing components and solutions, there’s only one company that you need to call; JJ Roofing. Founded in 1989, we have amassed a reputation for providing products that not just meet, but exceed, our client’s expectations. We focus on delivering both our trade and commercial customers with exceptional quality products at highly competitive prices.

Our BMI Redland Veltitech 145 (Product Code 92030) is a strong, yet lightweight, non-breather underlay. This product is particularly ideal as a replacement for a vapour-permeable underlay where eaves and high-level ventilation are already included.

NHBC requirements updated in Jan 2011 state that a vapour-permeable underlay must have high-level ventilation on New Build projects. At JJ Roofing, we’re proud to offer our BMI Redland Veltitech 145, which has just that. This product can also be used in conjunction with eaves and ridge ventilation as a price sensitive alternative to vapour-permeable underlay, making it suitable for a variety of uses.

With its robust construction, our BMI Redland Veltitech 145 can withstand the highest wind loading found in the UK, as well as other harsh weather conditions. Our non-breather underlay is high tear resistant, features tensile strength and excellent protection against rain,

For extra peace of mind, this product also features exceptional nail tear resistance, making it ideal for traditional work site construction. This is in addition to being suitable for conventional vented roof systems.

With delivery in just 3-5 working days, you can rest assured that your exceptional new BMI Redland Veltitech 145 will be with you in no time at all. Therefore, our outstanding products and superb delivery times will allow you to complete your project with minimal interruption.
