Abstract
A heated wheelchair ramp system includes a ramp constructed from at least one structural insulated panel (SIP) having a foam core sandwiched between two oriented strand board (OSB) panels. A polyaspartic coating covers the SIP panel for allowing the SIP panel to be resistant to outdoor elements. One or more heating elements are configured within channels in the SIP to provide heated to the SIP. A metallic sheet is configured adjacent to the heating element(s) to provide heat distribution to the OSB panel(s). Finally, at least one guardrail or handrail is secured to the side of the SIP for providing a safety barrier to persons using the ramp system.
