You may have had your conservatory installed five or ten years ago. In recent years glazing technology has revolutionised the use of the domestic conservatory as a functional addition to a dwelling! Many older conservatories use 16mm polycarbonate with a u-value of 2.6. Today, roofs accommodate 35mm polycarbonate which greatly increase the insulation as u-value’s of 1.5 can be achieved! In addition, the increased thickness greatly improves sound insulation.

Self-cleaning glass, with coatings that protect from the sun’s excessive heat and reflect energy back into the building, have transformed conservatory roofing. Added to this, the cavity between the glass can be filled with Argon gas which improves thermal insulation even further and reaches u-values of 1.0.
