Insulating Glass Windows and Doors: Tools to consider

Window glass and doors need insulating spacers and sealants to protect against weather induced expansion or contraction. Sealants and spacers also provide protection against fogging of windows due to condensation by providing a moisture barrier.

CRL Edgetech Super Spacer®: #SS31666

CRL Edgetech Super Spacer® is made from superior insulating silicone foam. The spacer essentially eliminates perimeter edge condensation and substantially reduces overall window heat loss. Because of the unique design features of Super Spacer® there are advantages in using this product for the fabrication of specialized insulating glass designs, including curved and odd shaped units, sound insulating, and triple-glazed units with art glass inserts.

For long-term durability, UV resistant silicone material is used to prevent spacer degradation. The flexible foam spacer accommodates glass bowing and thermal movement, and also helps ensure improved edge seal.  The permeability of the foam allows for fast moisture pickup with the 40% desiccant composition. To reduce moisture vapor transmission and inert gas loss, the Super Spacer® is backed by a high performance, multi-layer barrier film. Rolls are 66' (20.1 m) long.  Other colors and bulk rolls are available on special order.

CRL Black Silicone Foam and Metal Spacer I.G. Sealant:#:877

The sealant is compatible with the super spacer. Being made of urethane, the sealant is highly resistant to moisture and has long term durability. It is a single component urethane for the fabrication of quality single seal insulating glass units. Simply attach a SGT Polyethylene Sealant Guide to match your Super Spacer® width and backfill to the edge of the glass.

No. 877 is a special low-solvent formulation that is made to be compatible with Super Spacer's adsorbent, and does not require a polyisobutylene primary seal. No. 877 may also be used with adsorbent filled aluminum spacers. 877 Silicone Foam and Metal Spacer I.G. Sealant works best for assembly of Insulating Glass units when temperature is over 40°F (5°C), and when humidity is more than 40%. Tack free time is 45-60 minutes at 77°F (25°C). Cure time is 3/16" (4.8 mm) per 24 hours.  NOTE: Insulating Glass units should be totally sealed with Cat. No. 877 within one hour of exposing Super Spacer® adsorbent or adsorbent filled aluminum spacers to the atmosphere. Minimum order is one each.

CRL TruSeal Duralite: #DS6614

The CRL TruSeal combines spacer and sealant in one tape and can be used for both special shaped and standard windows. Duralite® takes optimum advantage of laminates and adhesives to reduce thermal conductivity, while improving surface and corner appearance over other insulating glass spacers. The CRL TruSeal features a multicomponent spacer assembly that has the dual advantage of both flexibility and stability. Duralite® allows the window fabricator to produce Insulating Glass units with one spacer system. The fabricator can increase productivity and flexibility, while eliminating customer concerns over having dissimilar spacers in special versus standard windows. The standard rolls are of 66 inches length, while eight different options in width are available.

CRL Clear Anodized 3/16" Wide Single Seal Spacer:  #3934

Heat loss costs money and energy, but it can be prevented. Insulating glass is the most effective product that we can provide to save energy and cut your heating and cooling costs. Traditional metal spacers for the fabrication of Insulating Glass units are available in both single and dual seal type. The CRL Single Seal spacer is available in bronze and clear anodized finishes.  The spacer is laser welded and is highly suitable for providing insulation of glass. Efficient insulation prevents heat loss which means lesser costs in cooling or heating for customers. Single Seal Spacers have deep shoulder that can allow for perfect sealant penetration.
