What is BS 5422?
BS 5422:2009 is the industry wide standard for determining and specifying the requirements for thermal insulation to pipework & equipment. BS 5422 is arguably the most important industry-wide standard for determining and specifying the requirements for thermal insulation used on pipe-work and equipment.
Which pipe insulation is best?
For many residential plumbing applications a PE pipe insulation product like Tubolit® and Tundra® is the perfect option. Economical and easy to install, PE foam insulation will prevent pipes from freezing and keep hot pipes hot and cold pipes cold.
Which British Standard outlines the thickness of insulation required in a domestic property?
Standard BS 5422
British Standard BS 5422 – an update.
What is ArmaFlex used for?
Select closed-cell foam insulation: ArmaFlex is the closed-cell elastomeric insulation invented to prevent condensation, moisture intrusion and loss of thermal efficiency. Use the Armacell ArmWin™ program to calculate the insulation thickness needed to maintain the surface temperature above the dew-point temperature.
What is the minimum recommended thickness for loft insulation?
between 250mm and 270mm
Current government recommendations are for loft insulation to achieve a depth of between 250mm and 270mm but some new properties are increasing their level of loft insulation to 300mm. Again, as long as the loft has adequate ventilation, this is fine. You may lose a little storage space but you will save money!
What is the thickness of Rockwool?
Depending on the application ROCKWOOL can make a board product up to 6” thick and a batt product 7.25” thick. ROCKWOOL products can also be layered to achieve a higher R-value when needed.
What pipe insulation has highest R-value?
Best Options Most foam pipe insulation is 3/8 inch thick with an R-value of 2, but heavy-duty foam pipe insulation, which is 5/8 inch thick, has an R-value of 4. Self-sealing foam insulation sleeves with R-values of 2 and 3 are also available.
Will pipe insulation keep pipes from freezing?
Insulation can help keep a pipe closer to the temperature of the water inside the pipe, but it does not add heat to the pipe and will not prevent freezing if the pipe is exposed to prolonged freezing temperatures.
How thick should the insulation be in an attic?
about 10 to 14 inches
Insulation levels are specified by R-Value. R-Value is a measure of insulation’s ability to resist heat flow. The higher the R-Value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate to R-38 or about 10 to 14 inches, depending on insulation type.
What is AP armaflex?
AP Armaflex, the world’s most recognized brand of closed-cell foam insulation, provides superior protection against thermal losses, condensation and moisture accumulation that leads to mold. It is the ideal choice for insulating mechanical piping systems.
What is the R value of armaflex?
aP armaflex Sheet and roll Insulation meets the energy code requirements of International energy Conservation Code (IeCC) and aSHrae for R-Value 4.2 at 1” wall thickness and r-Value 8 at 2” wall thickness.
Can I put too much insulation in my attic?
It’s possible to over-insulate an attic as too much will cause moisture buildup and eventually result in mold. Eventually, adding more insulation leads to diminishing returns in trapping heat as well.
