Packed: 1
- Designed to provide a clear airflow passage to a void beneath an insulated suspended floor - 8,000mm² airflow
- Current and future requirements of Part L of the Building Regulations along with other standards and regulations have led to an increase in the depth of thermal insulation in suspended floors along with an increase in cavity widths to accommodate greater amounts of cavity wall insulation
- This has meant that clear access to an underfloor void may be as far as 6 or 7 brick courses (525mm) below the level of an airbrick and potentially as much as 350mm from the outer face of the external leaf - traditional telescopic underfloor ventilators would not be able to achieve this without the use of additional vertical and horizontal extension sleeves
- The dual extended underfloor vent offers vertical telescopic adjustment of between 5 and 8 brick courses (318mm-575mm) without the need for an extension sleeve
- The horizontal outlet is long enough to bridge through an overall wall thickness of 350mm without the need for an additional extension
- The front aperture is designed for use with a combination airbrick or it can be used in conjunction with a traditional clay airbrick, although this would reduce the overall airflow through the system
- Regulations - BRE Digest 17, BRE Digest 262, Building Regulations C4, NHBC Standards 5.2 and BS 5250:2011 Control of Condensation in Building

Worth every penny
Format: Paperback
This book is in a class of its own compared to other security and pentesting books. I would highly recommend to anyone interested or currently working in network security. Instead of simply explaining how to use common pentesting tools, Wil Allsopp explains how they work and how to write your own custom tools from the ground up. Even if you do not have a programming background, it is worth understanding how an attacker can infiltrate a "secure" network without being detected.

Typos in the code make this a somewhat frustrating read. The content itself though raises good points and does a good job outlining some more advanced concepts

Format: Paperback
Bought yesterday, can't put it down -- will reread it again this week. This book is a solid gold mine on pulling our InfoSec heads out of our InfoSec tailpipes and focusing on the modes and methods our real adversaries are using. (Pro Tip: They aren't using crappy malware, so if you're InfoSec program is built on stopping malware you should be concerned.)
We all hear about the social engineering component to an effective attack, but to see it so effectively used over and over again with Wil's case studies really drives home the point.
If you're involved in either the management of an Information Security program, or involved in the more tactical parts of penetration testing, I'd put this on your short list of books to read this year. I hope he does a follow-up.

A well-written and updated book that covers Advanced Persistent Threats (APT) in detail.
Format: Paperback
The author truly knows his art. As a penetration tester, I feel that many books just re-hash the same old material and tools. This book covers much more than just pentesting, it covers APT and gives realistic scenarios and tools that actually work. This is a book for everyone who works offensive and defensive security because it covers how real malicious actors approach companies and steal their critical data.

Excellent Red Team InfoSec Book
Format: Paperback
One of the better books on the market on real penetration testing and creating advanced persistent threats. Great coding examples/strategies and how to think outside the box when it comes to attacking systems/companies. Elite guys like Wil Allsopp create their own custom tools all the time for real penetration testing. This is what nation-state actors are doing. Highly recommended.
