CornersealsCornerseals

To retrofit seals to a hinged swing window or door is simple if you use the CT Corner Grooving Tool. The hand held Grooving Tool cuts a 45° kerf into the corner of the jamb without removing most windows or doors. Tool comes complete with a vacuum hose and fittings to allow attachment to most vacuums. Openings can be cut in as little as 5 minutes and seals can be installed in less than 10 minutes with practice. CT Silicone Cornerseals are made from high quality silicone in various sizes and are flexible to -40°F. Gaps from zero to 3/8" can be sealed when choosing the correct size cornerseal. Customer find they can trim the barb off one size and insert it into the next size up to allow them to seal varying size gaps. We have reports that some older doors have used four or five different size seals on one side of the door! CT Cornerseal System has been approved for use on many historical buildings. Check with your local inspectors before using. CT Silicone Cornerseal are available in black, bronze or white and sold in 100 ft rolls. (View PDF of Corner Grooving Tool Instructions)

FoamFoam

During the construction of buildings, gaps and openings are created that need to be sealed to prevent unwanted movement of air circulating throughout the building frame. Building codes have a requirement that all penetrations in vertical or horizontal surfaces are to be sealed. By sealing all penetrations, the building framework can become compartmentalized, like a submarine, to prevent air movement. This means sealing both interior & exterior walls. When gaps are greater than 3/8" in width then installing low expansion foam is preferred over caulk.

Spray foam is available in single use cans and are supplied with a 6" straw to direct uncured foam to the desired location. Once these cans are started they must be used completely to avoid foam from curing in the straw.

If you need to have the ability to stop and start repeatedly, then you will need cans of foam designed to attach directly to a foam gun. The gun can be closed down between uses to prevent foam from drying in the nozzle. See Foam Gun Instructions.

VentilationVentilation

New building codes are requiring greater air tight construction, and ventilation is a major item that requires proper design and installation. Our occupant-sensing ventilation system allows several room grilles to be connected to a single, centrally located, continuously operating, exhaust fan. This system uses less energy and requires 44% less building penetrations than typical room fan systems.

Our room exhaust grilles were designed to open and close based on the amount of moisture in the air or movement sensed. Grilles are Humidity Activated, Motion Activated, Humidity/Motion Activated or Humidity/Switched Activated, all allowing a baseline amount of air to continually exhaust to meet minimum ventilation rates required by code. As the humidity level increases a damper on the grille opens to allow more air to pass. Humidity Activated grilles require NO electricity to operate. Using the natural hygroscopic properties of polyamide, an array of strips control the damper in the airflow. This array expands or contracts according to the relative humidity to which it is exposed. This ensures that the ventilation damper in the grille will always be opened when the relative humidity is high and will proportionally close as the humidity level decreases until it reaches the baseline ventilation setting. Motion Activated grilles will open to their maximum capacity for a predefined time period. At the end of this timed period the sensor will search for movement. If movement is detected then the grille will remain open an additional amount of time and then search again. This cycle will continue until there is no movement detected. Switched Activated grilles allow for manual over ride and will open damper to the maximum ventilation rate for a predefined period. Non-humidity activated grilles are operated using batteries or a central low voltage transformer.

BV21.010000Room Grille - Humidity Activated
BV21.010000

Humidity Activated room grilles allow a baseline amount of exhaust air to meet minimum ventilation rates required by code. As humidity level increases a damper on the grille opens to allow more air to pass. A great feature of this Humidity Activated exhaust grille is that it requires NO electricity to operate. Using the natural hygroscopic properties of polyamide, an array of strips control the damper in the airflow. This array expands or contracts according to the relative humidity to which it is exposed. This ensures that the ventilation damper in the grille will always be opened when the relative humidity is high and will proportionally close as the humidity level decreases until it reaches the baseline ventilation setting. Damper range is 8 CFM @30% RH - 50 CFM @74% RH. Unit is 6.9" x 6.7" x 1.8".

BV23.010009Room Grille - Humidity/Motion Activated
BV23.010009

Humidity/Motion Activated grilles can open based on humidity or movement and proportionally close by the relative humidity after the movement ceased. These are desired as a secondary exhaust grille in rooms where a water closet is located, separate to a larger bathroom, where higher ventilation rates may be required at times. Damper range is 8 CFM @30% RH - 50 CFM @74% RH if activated by humidity & 8 CFM - 50 CFM for 25 minutes if activated by motion. Unit is 6.9" x 6.7" x 1.8".

BV30.010009Room Grille - Motion Activated
BV30.010009

Motion Activated grilles open to their maximum capacity for a 25 minute period. At the end of this timed period the sensor will search for movement. If movement is detected then the grille will remain open an additional three minutes and then search again. This cycle will continue until there is no movement detected. Motion only grilles work well in powder rooms where the relative humidity does not vary. Damper range is 8 CFM - 50 CFM for 25 minutes if activated by motion. Unit is 6.9" x 6.7" x 1.8".
