Installing bubble insulation

New Metal Walls open interior. Bubble insulation can also help block radiant heat in post frame building structures inhibiting dew point condensation problems. Our bubble insulation also does not provide a growth medium or nutritive value for fungus, insects, or rodents. WHITE bubble reflective insulation is the ideal choice for insulating new concrete floors against loss of heat.

It can be used in conjunction with, or without, radiant heat tubing to help keep floors warm. The foil side is faced downwards to eliminate the concrete from coming in contact with it which could cause the foil to corrode due to the alkaline in the fresh concrete.

The Reflective Insulation Manufacturers Association consulted a firm specializing in thermal performance to help explain how reflective insulation works in a concrete slab application. Below is a direct quote from this study:. Thermal efficiency calculations were used to generate an estimate for a typical case involving reduction in heat loss for a common concrete floor system. The calculation is based on steady-state thermal conditions with an isothermal plane at the heating pipes and a plane between the gravel and the ground.

The ground temperature was 55 degrees Fahrenheit, while the temperature of the heating pipes was degrees Fahrenheit. The calculation assumes two inches of concrete R A reflective insulation material R The system R-value of R Reflective insulation is excellent as a basement wall insulator.

It performs as a vapor retarder, resists fungus and mold, and also controls dew point problems. There may be screws around each edge and in the center of the panel, so unscrew them all before lifting the panel. Write the panel number on the back side of each panel with a permanent marker, then place the panel on the ground. For the first panel you remove, write the number "1. Unroll the foil bubble wrap insulation over the metal joists, or purloins, that create the frame for the roof.

Attach it to the purloins with double-stick tape to hold it in place until you reinstall the roof. Go across the roof with the insulation so the seams are perpendicular to the purloins and roof panel seams. Cut it along the edges with a utility knife. Overlap the insulation seams by 2 inches. Seal the seams with reflective tape. Continue attaching the insulation and sealing the seams until the roof is completely covered. Why is bubble wrap a bad insulator of heat? It is not a good thermal insulator.

It does some airsealing which causes some decreases in energy use. The use as an air sealing solution ignores the concern for vapor issues. Visqueen sheeting is not used in walls and attics of buildings without damage from trapped moisture, and mold. What is double bubble insulation used for?

Double Bubble Insulation - Our most popular bubble insulation that is used for applications in metal buildings, pole barns, basements, crawl spaces and many other places that require a vapor barrier. Double bubble has a double layer of polyethylene bubbles to act an extra thermal barrier to prevent condesation. How well does reflective insulation work? Most common thermal insulation materials like fiberglass work by slowing conductive heat flow, but reflective insulation works a little differently.

Reflective insulation, installed in the attic ceiling, reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic. What is the R value of double bubble foil insulation? Since the product often costs more per square foot than 1-inch thick rigid foam rated at R-5, why would anyone use bubble wrap as insulation? Which side does the vapor barrier go on?

Vapor barriers are sheets of plastic or other material placed on one side of insulation sheets. This barrier is meant to keep moisture from getting to the insulation in the walls and ceilings, and it is required by building codes when insulating most houses. In any case, the vapor barrier must point to the warm side.

How thick should foam board insulation be? Foam board insulation is easy to use and is a great DIY way to add some insulation.

Some types of thicker foam board insulation are available, but they may need to be special ordered. Which way up does foil underlay go?
