1. What is a Roadstone Thermal Liteblock?
2. What is the strength, weight and size of the block ?
Compressive Strength 7.5N/mm2
Weight 11.2kg
Dimensions 440mm(L) x 100mm(W) x 215mm(H)
3. What is Part L of the Building Regulations?
The requirements regarding conservation of fuel and energy for new dwellings are laid out in Building Regulations (Part L Amendment) Regulations 2011 including the limitation of thermal bridging in the building fabric.
4. What is fabric first approach?
Energy efficient design begins with a fabric first approach whereby the buildings shape, orientation, thermal mass and a focus on detailing that limits thermal bridging will save energy.
5. What is a Y factor calculation ?
The DEAP calculation accounts for thermal bridging at junctions between building plane elements and around openings using a (y) factor.
6. What is a thermal bridge ?
Thermal bridging is a localised area of the building envelope where the heat flow is increased in comparison with that of adjacent areas due to the discontinuation of insulation at building junctions.
7. Where do I use Roadstone Thermal Liteblocks ?
The Roadstone Thermal Liteblock is required at key junctions to provide reductions in thermal bridging and heat loss.
8. Do I need to use a special mortar / plaster ?
Roadstone Thermal Liteblock provides excellent adhesive properties with traditional mortars and renders.
9. Is the Roadstone Thermal Liteblock CE marked?
The Roadstone Thermal Liteblock is CE marked in accordance with the requirements of I.S. EN771-3 to system 2+.
