Scope*1.1 This specification establishes requirements for insulatedvinyl siding, which is vinyl siding with integral foam plasticinsulating material, where the vinyl sid
3、ing is manufacturedfrom rigid PVC compound. Compliance with this standardrequires insulated vinyl siding to demonstrate a thermal insu-lation value of R-2.0 or greater. Other performance require-ments and test methods addressed by this standard includematerials properties and dimensions, warp, shrin
4、kage, impactstrength, expansion, appearance, thermal distortion resistance,and windload resistance. Methods of indicating compliancewith this specification are also provided.NOTE 1Insulated vinyl siding is composed of two major components:the vinyl siding and the insulating material. It is intended
5、that the vinylsiding portion comply with Specification D3679. Applicable portions ofSpecification D3679 are included in this specification. Additional require-ments that pertain only to the insulation as a separate material, or to thecombination of vinyl siding and insulation as a whole, are also in
6、cluded.For further explanation, see Appendix X1.1.2 Insulated vinyl siding shall be tested with the insulationmaterial in place or removed, as specified in the applicablerequirement or test method.1.3 The use of PVC recycled plastic in this product shall bein accordance with the requirements in Sect
7、ion 4.1.4 Insulated vinyl siding produced to this specificationshall be installed in accordance with Practice D4756. Refer-ence shall also be made to the manufacturers installationinstructions for the specific product to be installed.1.5 The values stated in inch-pound units are to be regardedas sta

Each block is to be 2.0 inches square. Theadhesive shall be applied and cu

45、m-patible with the adhesive according to the manufacturers guidelines, canbe used in place of the Douglas fir-larch blocks. Because in accordancewith 4.3.1.4.1 at least 75 % of samples must fail in a cohesive mode, asubstrate should be selected that is expected to be stronger than theadhesive and wh

Only specimens that failcohesively or do not fail are counted. Specimens that failnon-cohesively under a load at or below 100 psi are discardedand another specimen is tested until five specimens have eitherfailed cohesively, or have not failed at
