Ever wonder why you see more houses with light-coloured vinyl siding than dark? Vinyl siding colour comes down to personal preference but also differs in price with darker coloured vinyl siding often costing more than light coloured. But why the difference in price? Dark coloured siding requires enhanced heat resistance properties to resist the sun’s heat. Kaycan vinyl siding uses HELIOS thermal diffusion technology to resist distortion of the vinyl siding from heat. This technology adds to production costs and explains why darker coloured vinyl siding costs more. Everything Exterior Store in Edmonton carries high quality vinyl siding in both dark and light colours.
