Thermal Insulation included

The facades are mainly responsible for the ener-

gy balance of a building. The excellent thermal

insulating effect of bonded double or triple

glazed units with coated glass can save much of

the energy otherwise consumed for heating or

cooling.The air trapped between the bonded

panes is a poor heat conductor and therefore

forms a good insulating layer between the out-

door and indoor air.

The insulating glazing edge seals are predomi-

nantly made of bent aluminium or stainless steel

spacers filled with a desiccant,thermoplastic

polyisobutylene (PIB) as a primary seal and in-

stallation aid, and an elastic sealant as a sec-

ondary edge seal.Only high-modulus silicone is

approved as a secondary seal in structural glaz-

ing facades.Sikasil IG silicone sealants

were specifically developed to meet require-

ments of insulating glazing and feature special

advantages:

UV and weathering resistance

Durability

Material compatibility

Natural Stone Sealing perfect even in sensitive Areas

Sealants suitable for naturalStones

Natural stones such as granite,marble and

sandstone are highly sensitive materials

when used on facades.Where an inappro-

priate sealant is used, there may be stain-

ing of the joint edges or streaking,which

greatly impairs the optical appearance of

the facade.Sika therefore recommends

special system-compatibleSikasil WS

silicone sealants ideally suited for use with

extremely sensitive natural stone ele-

ments,or connecting metal facades and

curtain walls to natural stone elements.

They contain no volatile compounds that

could migrate into the pores of the natural

stone.We therefore describe them as non-

staining.These non-staining silicone

sealants are also recommended for glass

facades in order to reduce streaking on

glass panes and metal panels and to mini-

mize the need to clean the facade.

Important

Since all natural stones are verysensitive materials, a on-staining

test should be carried out at one

of our Facade Competence Centres

before any natural stone sealing

operation.This is an essential pre-

condition for non-staining warranty.
