Internal roof insulation

Thermal insulation, which is required mainly for homes in order to slow down the flowing in or out of heat, is often added to walls, roof, ceilings, or floors.  As heat primarily escapes through conduction or physical contact with the colder temperature outside, construction and insulation of walls and roofs are crucial to keeping heat inside.


For buildings that were built with poor roof or wall insulation, remodeling could become a big burden, which usually involves taking off of the original roofing panels, and purchasing new insulation panels.


Steel sandwich panels are among the most commonly used material for building either industrial, commercial, agricultural, or public domains.  Sandwich panels can often be tailored to suit various thermal, acoustic or strength requirements by combing layers of different materials in different thicknesses to achieve the desired effect.


Self-Drilling Screws for metal roof installation

As mentioned in our other article: Step by step tutorial on choosing the correct screw type for roofing applications, it is important to understand and choose the correct screw type of the job.  BDN Fasteners offer a complete fastening solution which consists of various screw types for your insulated roofs or walls.
