Keystone Lintels are manufactured from high quality grade galvanised steel with minimised spangle finish. All cut edges are treated with corrosion resistant paint.
The Keystone Lintel core is entirely filled with ‘CFC free’ insulation, which completely fills all voids in the lintel, particularly at the apex ensuring continuity with wall insulation and reducing cold bridge effect in this area. This ensures that the Keystone Lintel range is one of the most thermally efficient lintels available with a thermal conductivity of 0.033 W/mk.
Keystone Lintels are manufactured to the highest quality and are continually assessed by the BSI to ensure our quality assurance systems comply with BS EN ISO 9001: 2008.
Keystone Sun Lounge Lintel
A Sun Lounge Lintel is an easy way to add space at low cost when building a new house, or extending a property. An extra room rather than an add-on, a Sun Lounge is comfortable all year round while allowing you to watch the seasons come and go in comfort.
It is universally recognised amongst home owners and house builders that a Sun Lounge is a more practical, user friendly room than a conservatory. Furthermore it is agreed that a Sun Lounge floor area can be included in the overall measurement of your house size, adding much more value to your home.
