What is thermofiber board?
THERMAFIBER Industrial Board is an economical, semi-rigid, preformed mineral fiber insulation that offers excellent thermal and acoustical performance in both hot and cold applications.
How does thermofiber insulation work?
Thermafiber insulation reduces the transfer of heat (and cold) through building structures or envelopes by providing a thermal resistance range of 3.7 to 4.2 per inch depending on product type. Thermafiber Insulation not only reduces energy use and therefore CO2 emissions, but in addition, also provides thermal comfort. Thus the same holds true for the industrial/manufacturing sector.

Does hemp insulation hold moisture?
Here is one of the benefits of hemp and grass insulation – they both have the ability to safely store higher levels of moisture than most materials. This can be a hard concept to grasp at first, so think of it the same way thermal mass absorbs and releases heat (meaning - the way stone, concrete, wood, water, substances with a lot of mass absorbs and holds heat). When relative humidity levels inside your home or walls change, some of that moisture will be absorbed and released by the materials in your home. And, as it's that time of year when condensation on windows can indicate a problem, having some safe passive humidity storage is never a bad thing in homes.
Is natural insulation good for a house?
Some natural insulations are better suited to slip into the more ‘mainstream’ yet ‘green home leaning’ building industry than others, which are the ones that can replace existing products without being too noticeable. By being ‘noticeable’ I mean things like straw bale home construction which is a thing of its own, or recovered sheep wool insulation from local fields as another example, which might apparently make your house smell like an old barn in the Sottish Highlands during prolonged rainy weather. That....would be noticeable. (unless of course using an actual cleaned and manufactured natural wool insulation product which is now possible.)

And while fiberglass insulation can contain up to 30 percent recycled glass, it’s no match for the impressive 80 percent recycled content that some insulation options can offer. For something with such a simple concept, insulation comes with a huge variety of options. But have no fear, our complete eco-friendly insulation guide is here!
How is insulation effectiveness measured?
Insulation effectiveness is measured by its thermal resistance value, or R-value, a number between 1 and 60 that reflects the material’s resistance to heat transfer. The better the insulation, the higher the R-value. This number is determined by the type of insulation, its thickness, density, and where and how the insulation is installed.
Why is insulation important?
Insulation is one of the most important factors that contribute to a home’s energy efficiency – or inefficiency. With improper insulation, a homeowner spends more on heating and cooling, which uses more resources to run, and costs more money.
Why is insulation needed in roofs?
The point of insulation is to combat the movement of air. And since air can move in all sorts of directions , insulation is needed in roofs, ceilings, walls, and floors to prevent air from entering and leaving.
Why do you need an air exchanger for a ventilation system?
Because its sealing powers are so strong , a ventilation system needs to be installed – and if you live in a cold climate, the ventilation system also needs an air exchanger. Icynene costs three times as much as fiberglass and with the additional systems required, the upfront costs are expensive.
What is sheep wool used for?
You’ve heard of using sheep’s wool in clothing and blankets to keep us warm – but what about in our walls and ceilings? The plush yet fire-resistant material works just in our homes as it does on a sheep. Compressed wool fibers form air pockets that trap air to keep us cool in the summer and warm in the winter. The breathable material’s inner layers absorb moisture without feeling damp or affecting its ability to retain heat. Because of wool’s properties, you don’t need to constantly adjust your heating and cooling systems, which saves energy and money.
