Q:What are the insulation values for the Hormann sectional doors?
The four important characteristics of thermal insulation, acoustic insulation, tightness and sealing, and wind loading for garage doors are all tested and certified by Hormann.
These are important factors for the choice of door over and above the mandatory safety requirements. The thermal and acoustic insulation properties for the modern garage, sealing against adverse weather effects and resistance to wind pressure in particularly windy regions are all far more important in the UK than ever before.
Hormann LPU42 and LPU67 insulated sectional garage doors offer the very best performance in all these areas.
Thermal insulation
Double-skinned steel doors 42 mm - LPU42 Section U = 0.5 W/(m2/K) Door leaf U = 0.9 W/(m2/K) Fitted door 1) U = 1.4 W/(m2/K)
Doors with solid timber infill LTH40 Door leaf U = 2.5 W/(m2/K) Fitted door 1) U = 3.0 W/(m2/K)
Acoustic insulation Double-skinned steel doors 42 mm R = approx. 25 dB
Sealing
Air
Single-skinned steel doors Class 0
Double-skinned steel doors Ribbed (not L-ribbed) Class 2
