What it's used for

  • Subfloor decking on timber joists in new builds and refurbishments
  • Loft boarding to create usable storage space over ceiling joists
  • Flat roofing decks as a structural sarking layer beneath the waterproof finish
  • Wall and ceiling sheathing where a structural panel with moisture resistance is required

Fitting and handling

Allow boards to acclimatise in the installation area for at least 24 hours before laying, particularly in loft or ground-floor subfloor situations where temperature and humidity can vary. Fix through the face into joists at 150mm centres around the perimeter and 300mm centres internally, using ring-shank nails or screws appropriate for the joist depth. Leave a 3mm expansion gap at walls and perimeter edges to allow for seasonal movement.

FAQ

What is the difference between OSB2 and OSB3 flooring boards?

OSB3 is rated for structural use in humid conditions under EN 300, whereas OSB2 is only suitable for dry interior conditions. For subfloors, loft boarding or roofing decks where moisture exposure is possible, OSB3 is the appropriate choice and is widely specified by UK building regulations and warranties.

Can T&G OSB3 be used as a finished floor surface?

OSB3 tongue and groove boards are intended as a structural subfloor rather than a decorative finish. They are designed to receive floor coverings such as carpet, vinyl, ceramic tiles (with suitable adhesive) or engineered flooring. The surface texture is not suitable as a standalone wear layer in occupied spaces.

What joist spacing is 18mm OSB3 rated for?

18mm OSB3 T&G flooring boards are generally suitable for joist centres up to 600mm, which aligns with the 600mm board width so joints always fall on a support. For spans up to 450mm centres the boards perform well under standard domestic loading. Always confirm with your structural requirements and local building control where applicable.

An incredible guide for your Advent journey.
Format: Paperback
Thank you Miriam for bringing us this beautiful and deep guide for our Advent journey. I used it for the first time in 2023, and will definitely be using it again in 2024. I loved and looked forward to every day that I sat with the daily passage. Miriam guides us into daily Scripture, and includes questions for us to meditate on and apply those passages. In addition, she adds her own meditation, which offers a rich perspective. It is accompanied by Lilias Trotter's own perspective through her words and wisdom and gorgeous art. The author invites us into self-reflection multiple times through each daily passage and includes poetry and song that binds each daily message. I will definitely give these as gifts for next year, and I am so looking forward to walking through it again next Advent. It will be interesting to see the Lord's living and active wisdom reveal itself year after year. I would highly recommend keeping a journal as you dive in to this rich, rewarding journey.

Good news, bad news.
Format: Paperback
I like the product, but because it was inadequately packaged, the top of the book is imperfect. It's certainly readable, but if I am paying full price, I expect a perfect copy.

Deep Into the Financial Nuts and Bolts
Format: Paperback
This a very, very informative book about the financial crash of 2008 and its lengthy recovery. The British author is a fine writer and definitely appears to master the subject. His background is as an economic historian and his approach to the financial collapse is thru the lens of political economy. For a European, he is very charitable towards the failures of the US markets and the responses of the US govt in the crisis. In fact, he is much more critical of the Germans and the British and the EU govts in their involvement in the crisis and their failure to more effectively guide the Eurozone out of the financial crisis. The book is somewhat dense and daunting and is 616 pages of text. Definitly not for the faint of heart or those who are not somewhat financially and economically literate. It does not lend itself to speed reading. A glossary and list of abbreviations would have been very helpful--as other commenters have suggested. Abbreviated acronyms of organizations, treaties, agreements,govt agencies, etc. come flying fast and furious. Still, with due and diligent effort on the part of the reader, you can see how very well the author knits his technocratic financial narrative together. The negative reviews often seem poorly informed. It's a difficult book to get thru. Some readers appear to dislike the author because he is a Keynesian liberal. I understand that, but they should note that he tends to be very positive about US govt financial leadership leading the world out of the crisis. Some don't like the fact that he thinks Trump is a grifter. Unfortunately, Trump is, irrefutably, a grifter and a con man. The only areas where I found myself disagreeing with the author were on the issues of immigration and protectionism. The Eurozone and the US cannot support unrestricted immigration. There are too many millions in the world of 8 billion people who would kick down the gateways of either entitity to gain entry. Unrestricted immigration is an existential threat to all the Western countries involved. Sober assessment of reality is something other than "racist". "Realistic" is a far more accurate term. The author is a classic liberal and against national "protectionism". However, this is 2023. The book was written in 2017. Much water has passed under the bridge since then. Countries are political entities with borders. Too often--as the writer points out--economic and financial advisors forget the "political" part of "political economy". Trump's legions are there to remind them. At least they are good for something. Protecting your economy from essential foreign supply chain failures and from hostile foreign competitors is just good governance. And insuring that others share in general prosperity besides coastal elites is another part of good governance. "Flyover Country" is every bit as important as the two coasts. Probably more so. Never forget the "political" part of "political economy".
