Installation guidelines

G2.01



RESEARCH TOPIC: INSULATION

INSULATION

Three types of insulation were researched for rehab applications; spray foam, batt, and blown.

Insulation helps reduce building energy demand while improving thermal comfort for the occupants.

Attic - insulation is essential for keeping out cold air in the winter and hot air in the summer

Floors and Walls – Adding insulation to floors and walls will help improve noise control in the home as well as thermal performance.

G2.02



RESEARCH TOPIC: INSULATION

SUMMARYBatt insulation

Use: Any exterior wall where drywall or exterior siding has been removed. Floors over unconditioned spaces.

Brand: Owens Coring Fiberglass, contains 20% post-consumer and 30% pre-consumer recycled content

Spray foam insulation

Use: Any exterior wall where drywall or exterior siding has been removed. Floors over unconditioned spaces. Rim joist or anyplace the structure meets the foundation. In attic where interior walls meet attic space.

Brand: Eco Tec Insulation uses Icynene spray foam which are PBDE-free. Made with castor oil rather than petroleum-based polyol.

Blown insulation

Use: Un-insulated attics or adding to existing attic insulation.

Brand: Owens Coring Fiberglass, contains 20% post-consumer and 30% pre-consumer recycled content

G2.03



RESEARCH TOPIC: HOUSE WRAP

HOUSE WRAP

Housewrap functions as a weather-resistant barrier, preventing water from getting into the walls while allowing water vapor to pass to the exterior. If moisture from either direction is allowed to build up within stud or cavity walls, mold and rot can set in and the insulation will lose its R-value due to heat-conducting moisture.

House wrap will also serve as an air barrier if it is sealed carefully at seams.

G2.04



RESEARCH TOPIC: HOUSE WRAP

SUMMARYPrevent bulk water intrusion.

Reduce air infiltration.

Water vapor permeance.

Brand: DOW WEATHERMATE Plus

Takes ten times longer for water to infiltrate than Tyvek.

Six times better at reducing air infiltration than Tyvek.

Optimal vapor permeability of 6.7 perms. Tyvek has a permeability rating of 58 perms.

Higher tear resistance, twice the strength of Tyvek.

G3.07



RESEARCH TOPIC: Cabinets & Countertops

Cabinets & Countertops

The kitchen is often the most useful part of the remodel and can really help to enhance the home. Because of this, making it an efficient space, easy to clean and maintain as well as a safe environment to be and prepare food in is an extremely important part of the rehab.

Countertop Options

-Laminate

-Bamboo

-Concrete/Cement/Resin (w/ recycled glass)

-Recycled Paper

Cabinet Options

-Bamboo

-Wheat-board

-Wood-fiber

G3.08



RESEARCH TOPIC: Cabinets

Bamboo

Bamboo cabinets qualifies for LEED credit MRc6.

Highly renewable

Durable and attractive

Constructed with low-VOC and or formaldehyde-free adhesives makes for a safe indoor environment.

G3.09




Wheat-board

Wheat-board cabinets are composed of wheat straw fiber.

Annually renewable resource material

Made from wheat waste product that would otherwise be burned and pollute the air.

Superior moisture resistance.

G3.10




Wood-fiber

Wood-fiber cabinets are composed of reclaimed FSC certified wood salvaged from demolition sites.

Bound together by a water-based resin formula that is both petroleum-free and VOC-free.

Veneered with FSC certified products to give any appearance.

G3.11



RESEARCH TOPIC: Countertops

Laminate

Laminate still seems to be used as the “best practice” available when it comes to countertops. Its cost effective, sufficiently durable, attractive, easy to clean and readily available.

Generally not environmentally friendly, especially through production.

Formaldehyde adhesives and finishes are often still included in finished product manufacturing process.

G3.12




Concrete/Cement/Resin

Depending on the skill level of the volunteers or other experienced crew members, concrete, cement and resin countertops have become a popular sustainable product. For added sustainable purposes, as well as appearance, broken, recycled glass has been mixed into countertops. (This often ends up with a finished look somewhat resembling expensive quartz countertop.)

G3.13




Bamboo

End grain bamboo countertops have become another sustainable option for countertops.

The most important aspect to the sustainability with this type of surface is the way it is assembled, specifically the bonding adhesive used to assemble it. Like all other adhesives, it is best as a formaldehyde-free product.

This type can be cut with any wood-working tools, proving a volunteer friendly material.

G3.14




Recycled Paper

Recycled Paper countertops are assembled with a nonpetroleum, formaldehyde-free resin base. Some are even made from a cashew nut shell liquid.

They use postconsumer recycled paper that is FSC certified.

This type can be cut with any wood-working tools, proving a volunteer friendly material.

Typically ends up looking like a laminate surface, or a Corian top.

G3.15



RESEARCH TOPIC: LOW VOC PAINTS

LOW VOC

•Using low VOC paints improves air quality in the

home.

•Current Valspar paints in use.

•Interior Primer (#44-990)

•Latex Ceiling Paint (#27-1426 )

•Interior Eggshell Wall & Trim ( # 27-4400 )

•These interior paints are Low VOC and they range

from $25 to $37 per gallon.

G3.16



RESEARCH TOPIC: LOW VOC PAINTS

SUMMARY

•Consider using Valspar no-VOC paints.

•High quality no-VOC paints can be equally as durable as low-voc.

•Low VOC paints are generally white. Adding color pigments will increase the VOC level, with the darker the paint having higher VOC levels.

G3.17



RESEARCH TOPIC: LUMBER

FSC LUMBER

•Lumber should be produced in an environmentally responsible manner.

PRESSURE TREATED LUMBER

•The greenest treated-wood option for lumber today involves a sodium silicate and heat treatment. The resulting material is nontoxic and highly resistant to insects and decay.

G3.18



RESEARCH TOPIC: LUMBER

SUMMARY

•The Forest Stewardship Council (FSC) is the only certification system to offer genuine certainty about responsible forest management.

•Do not let retailers talk you into buying any other certified product.

•There is a FSC product database where you can search for manufacturers and distributors, but not retailers. [www.fsc-info.org]

•During the ACQ and CA treating process, wood becomes saturated with a chemical solution carried in water. After this process, the wood takes several months to dry depending on the climate region.

•Some treated wood has large amounts of copper, standard steel fasteners will corrode up to five times faster than when used in untreated wood.

G3.19



RESEARCH TOPIC: ALTERNATIVE FLOORING

CURRENTLY IN USE

•VCT

•price: $2 per square foot.

BAMBOO

• Rapidly renewable material that is as durable as other wood flooring, if not more. •Price: $2-6 per square foot

LINOLEUM

•Made from natural and renewable materials.•Price: $5 per square foot

G3.20



RESEARCH TOPIC: ALTERNATIVE FLOORING

SUMMARY

•Depending on the finish, bamboo flooring can range from 2-6$ per square ft.

•There are 3 native species in North America. Research is being done to aid the bamboo production in the United States.

•Most manufacturers are not FSC certified.

•Linoleum is an organic product made from linseed oil and wood flour or cork dust over a burlap or canvas backing.

•Vinyl is made from Poly Vinyl Chloride (PVC) resins combined with plasticizers.

-Vinyl requires the use of petroleum based chemicals and comparative large amounts of energy to manufacture.

G3.21



RESEARCH TOPIC: REUSE OF MATERIALS

WHAT?

•The reuse of salvaged materials in the same or related capacity minimizes the need to produce more, or buy more.

•Also limits the amount of waste going to landfills.

G3.22




SUMMARY

•Materials can be salvaged by the volunteers.

•Some materials may have been exposed to hazardous materials and would require an evaluation.

•Consider making a list of materials usually found in rehabs and have potential to be reused: Old doors, shelves, hardware, furniture, bricks, stones, plants, etc.

G3.23




SUMMARY

•Proposition: A more concrete cabinet reclaiming system through which both the contractor and DHFH can benefit more frequently.

•Information

•Marketing

•The contractor could then sign up for a service scheduling a pick-up date for DHFH at their project’s site.

•DHFH provides IRS form #8283

•Quality/condition of materials determines use in a remodel, or to be sold at ReStore.

-If quality/style of cabinets received is considered too variable and fairness is an issue, the cabinets should go directly to ReStore.
