Basement Insulation – Washington

Easy & Efficient Basement Insulation For Washington

The X-Bracket System is the new and better way to install basement insulation! Closed cell spray foam is installed continuously, creating a continuous vapor, air, moisture and radon barrier in a continuous, monolithic layer of spray foam.

Electrical rough-in is easy with the X-Bracket System – simply clip wires into the built-in electrical clips. There is no need to drill holes for electrical wires. The X-Bracket System provides flood-resistant durability, minimizing water damage and preventing mold growth. 

You and your basement deserve a fast & effective way to insulate your Washington basement!

Making Basement Insulation Easier In Washington!

Increase space in your basement with the low-profile X-Bracket System, while maximizing energy efficiency. The X-Bracket System allows closed cell spray foam to be used continuously on a basement wall without air gap framing, meeting building code with less spray foam. The continuous layer of spray foam also acts as a soil gas barrier to protect your home from radon.

Zero Thermal Bridging
The X-Bracket System allows spray foam to be used continuously without thermal bridging, achieving maximum performance from your basement insulation insulation, lowering energy bills and providing maximum comfort.

Easy Electrical Rough In
Romex or metal clad wire can be easily clipped into the electrical clips on the X-Brackets, then are locked in place when spray foam is installed. There is no need to drill holes in the studs to pull electrical wires, speeding up electrical installation. 

Engineered for Simplicity & Speed
The X-Bracket System is pre-engineered to handle loads
of TV’s and cabinets. The X-Brackets incorporate a
proprietary glue surface to create a, extremely strong
bond with the concrete 

Flood & Moisture Resistant Construction
The spray foam and polymer X-Brackets are resistant to mold and decay. In addition, metal hat channels can be used instead of wood furring strips to eliminate the possibility of water damage or mold.

Protect the Home From Radon
Only 1.25″ of closed cell spray foam is required to effectively mitigate radon infiltration into your basement. Spray foam is also much easier to install than traditional radon mitigation systems, and all penetrations are completely sealed.

Maximize Space In Your Basement
The low profile design of the X-Bracket System maximizes space with a profile 2″ to 4″ less than traditional basement insulation & framing methods.
