Duct Board Insulation for an Attic or Basement

Insulation is among the house improvement solutions that help homeowners make dramatic savings on energy bills. Additionally, it leaves your house convenient to live in. The loft and the cellar are two areas in your house which may gain from insulation. Duct board insulation basement walls and loft roofs maintain your house warm in the winter and cool throughout the summer when keeping moisture out.

There are various sorts of polyurethane insulating material and you have to find the one which gives you the sum of insulation and moisture control which you want. Efficient duct board insulation is sprayed on walls into hard-to-reach places. It might be retro fitted, which makes it perfect for insulation present structures and attics and basements where there could be unsightly ceilings or walls.

Different types of Duct Board Insulation Materials

• Cementitious: This can be cement-based foam called sprayed-board or foamed-in-place insulating material.

• Phenolic: Phenolic or even phenol-formaldehyde foam has been widely used from days gone by as stiff duct board insulation. It's a comparatively high insulation material property. Its key disadvantage is the fact that it could shrink as many as 2 per cent after healing. 

• Polyurethane: This is actually a closed-cell duct insulating material and also one of the finest insulation materials you are able to find. Polyurethane insulation can be found as stiff duct board and liquid coated foam.

How To Make a Duct-Board Plenum

Duct board is made up of compacted fiberglass supported by a foil vapor barrier. The insulating material properties of compacted fiber glass lessens the temperature loss from air flowing throughout the plenum and prevents condensation from forming on the surface of this duct plenum. Excessive condensation will probably damage finished compounds enclosing the plenum and lead to mold to develop inside dampened metal framing components.

Step 1 : Set a sheet of duct board onto a firm surface with the foil vapor barrier sitting on the work surface. To get more information you can search duct boards panels and duct board insulation through online resources.

Step 2 : Pull the tape measure across the part of the duct board. Mark 1-1/2 inches from 1 end of this duct board having a soapstone. By the 1-1/2-inch markers, assess the elevation of one's own duct and 1-3/4 inches and then place the next soapstone markers. Place the brief side of this t square against the face of the duct board. Align the extended border having cut markers. Pull the soapstone across the edge of this T Square to indicate the lineup. 

Step 3 : Twist the duct board knife over the diameter of the duct board. Drag the knife vertical across the 1-1/2-inch markers. Remove the inch – 1/2-inch part of cut insulating material.

 Step 4 : Pull the V Groove tool together each marked line. Maintain the horizontal area of this V Groove tool flat against the surface of the duct board to guarantee the top are at the appropriate thickness. Eliminate the searing insulation from every groove.

Step 5 : Twist the foil flap-over and basic the flap into the strand board. Seal the bond with a period of foil tape.

Step 6 : Secure the end caps into the plenum. Push the trim bits in each open end of this plenum. Slit the foil vapor barrier stretching beyond the borders of the duct board having a duct tape knife. Staple the transparency into the strand board. Tape the flaps down using foil tape to fill out the duct board plenum.
